Connecting kdb+ to R - r

I'm trying to run a make file to install qserver on my OSX machine.
The make file gives me an error when I try to run. see code below:
make
/Library/Frameworks/R.framework/Resources/bin/R CMD gcc -g -O -fpic -m64 -shared -D KXVER=3 -I. -I/Library/Frameworks/R.framework/Resources/share/include base.c c.o -lpthread -L/Library/Frameworks/R.framework/Resources/share/lib -lR -o qserver.so
/Library/Frameworks/R.framework/Resources/bin/R: /Library/Frameworks/R.framework/Resources/bin/R: cannot execute binary file
make: *** [all] Error 126
Hoping someone can give me a pointer here on how to fix it.

Do you have the right version of gcc? I build with gcc-4.8 and have no issues. I recall a thread on the kdb list that mentioned the build required some features available only in later gcc versions. Give that a try.
[EDIT]
Nevermind, just saw that the error says the R binary was not found. Edit the make file to use the appropriate path for your R installation. If you don't have R installed, I suggest installing with homebrew:
brew tap homebrew/science
brew install r
After that you can replace the path in the Makefile as appropriate. I personally changed the Makefile to use $(shell R RHOME) to find the R home path, rather than assume a specific location.

JPC was partially right about gcc.
My system had two different versions of gcc loaded and the default was the standard one. I changed the makefile to run 'gcc-4.8'.
Once I finished that I got a new error: the make file couldn't locate my 'R.h' file...so i just had to reference where my r h-files were located....once I did that the make problem executed.

Installing R on OSX Big Sur (EDIT: and Apple M1) for use with Rcpp and openMP

There's probably a gazillion threads on OSX+Rcpp+openMP, but the bottom line right now appears to be this (per coatless):
Unfortunately, with R 4.0.0 the CRAN distributed version of R loses
the ability to use OpenMP without a custom setup.
I came across other ideas, including compiling llvm yourself, using homebrew or macports to install R and/or llvm and/or gcc, and then figuring out how to use the right compiler and/or flags with (R)cpp. However, I find this all very confusing.
I am not a mac user, but it seems to me that setting up a mac to compile Rcpp packages or code snippets with openMP seems to be too difficult for most mac users. However, I would like my R package on github to be used by more users, and since it relies on openMP, I am losing that audience.
Can someone provide the necessary steps to set up R on mac in a way that it can compile Rcpp code with openMP? I'd like to turn that into a quick tutorial.
EDIT: I should have added - on Apple Silicon, because there are some extra confusions where things go - /usr/local vs /opt
I spent a day figuring this out (original post here); here are the steps I used to compile R packages from source with openMP:
Install xcode from the app store (instructions for installing xcode) then install/reinstall the xcode command line tools from the terminal:
# To delete an existing command line tools installation:
sudo rm -rf /Library/Developer/CommandLineTools
# To install the command line tools
sudo xcode-select --install
Install gcc via Homebrew (instructions for installing Homebrew) or, if you already have gcc installed, skip to step 3.
# WARNING: This can take several hours
brew install gcc
To avoid "legacy" version issues:
brew cleanup
brew update
brew upgrade
brew reinstall gcc
Link some headers into /usr/local/include
sudo ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/* /usr/local/include/
# You can ignore warnings like this:
#ln: /usr/local/include//tcl.h: File exists
#ln: /usr/local/include//tclDecls.h: File exists
#ln: /usr/local/include//tclPlatDecls.h: File exists
#ln: /usr/local/include//tclTomMath.h: File exists

#ln: /usr/local/include//tk.h: File exists
#ln: /usr/local/include//tkDecls.h: File exists
#ln: /usr/local/include//tkPlatDecls.h: File exists
Check your version of gfortran (cd /usr/local/gfortran/lib/gcc/x86_64-apple-darwin19/; ls) then edit your ~/.R/Makevars file (if you don't have a file called Makevars in your ~/.R/ directory) and include only these lines:
LOC = /usr/local/gfortran
CC=$(LOC)/bin/gcc -fopenmp
CXX=$(LOC)/bin/g++ -fopenmp
CXX11 = $(LOC)/bin/g++ -fopenmp
CFLAGS=-g -O3 -Wall -pedantic -std=gnu99 -mtune=native -pipe
CXXFLAGS=-g -O3 -Wall -pedantic -std=c++11 -mtune=native -pipe
LDFLAGS=-L$(LOC)/lib -Wl,-rpath,$(LOC)/lib
CPPFLAGS=-I$(LOC)/include -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include
# (check that the version of gfortran - in this case 10.2.0 - matches the version specified in FLIBS)
FLIBS=-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin19/10.2.0 -L/usr/local/gfortran/lib -lgfortran -lquadmath -lm
CXX1X=/usr/local/gfortran/bin/g++
CXX98=/usr/local/gfortran/bin/g++
CXX11=/usr/local/gfortran/bin/g++
CXX14=/usr/local/gfortran/bin/g++
CXX17=/usr/local/gfortran/bin/g++
Open R and install a package to test that it compiles with openMP enabled (when asked, compile from source = "Yes"):
install.packages("data.table", type = "source")
Unfortunately, I do not believe a more "simple" setup exists.
Eventually, I found a process that works on a M1 mac with Big Sur.
Head over to https://mac.r-project.org/, it contains most things you will need
Download and install R via R-4.1-branch.pkg. The CRAN version might also work, but I used the installer from mac.r-project.org, which required opening the osx security settings to allow the installation.
Install RStudio, start it, and let it install the developer tools. Alternatively, run sudo xcode-select --install in Terminal.
Head to https://mac.r-project.org/openmp/. Download openmp-11.0.1-darwin20-Release.tar.gz and install it (see Terminal commands below).
curl -O https://mac.r-project.org/openmp/openmp-11.0.1-darwin20-Release.tar.gz
sudo tar fvx openmp-11.0.1-darwin20-Release.tar.gz -C /
Now we need to add compiler flags so that clan uses openMP. In Terminal, create the Makevars file.
cd ~
mkdir .R
nano .R/Makevars
in nano, paste these additional compiler flags into the Makevars file:
CPPFLAGS += -Xclang -fopenmp
LDFLAGS += -lomp
Hit Control+O, Control+X to save and close
Head over to the gfortran page: https://github.com/fxcoudert/gfortran-for-macOS/releases
Use the installer gfortran-ARM-11.0-BigSur.pkg to install gfortran.
For some reason it appears to install in /usr/local/gfortran, but R expects it in /opt. The mac-R team likes to separate arm64 and intel related files. We could go and fix paths, or simply also install gfortran under /opt. Download the tar file gfortran-ARM-11.0-BigSur.tar.xz. You can use curl, or just download it and point tar in the command line to it.
cd /opt/R/arm64/
sudo mkdir gfortran
sudo tar -xzyf gfortran-ARM-11.0-BigSur.tar.xz -C /opt/R/arm64/
(replace gfortran-ARM-11.0-BigSur.tar.xz with /users/YOURUSERNAME/downloads/gfortran-ARM-11.0-BigSur.tar.xz)
Now it should work.
Not an expert in OSX, but doing this so others can figure out how to use my R package. I'd like to streamline the process some more, but wiping the mac, reinstalling osx and testing it takes so much time.

'RcppArmadillo.h' file not found when installing RcppArmadillo from source

RcppArmadillo 0.8.400.0.0 works just fine on my computer, both from sourceCpp and cxxfunction. Now I want to upgrade to 0.8.500.0, which requires compilation from source. Then I got the error
ccache /usr/local/clang6/bin/clang++ -std=gnu++11 -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -I"/Library/Frameworks/R.framework/Versions/3.5/Resources/library/Rcpp/include" -I/usr/local/include -I/Applications/CPLEX_Studio128/cplex/include -I/Applications/CPLEX_Studio128/concert/include -DIL_STD -fPIC -Wall -g -O2 -c RcppArmadillo.cpp -o RcppArmadillo.o
RcppArmadillo.cpp:22:10: fatal error: 'RcppArmadillo.h' file not found
#include <RcppArmadillo.h>
^~~~~~~~~~~~~~~~~
1 error generated.
I got this error whether I ran install.packages("RcppArmadillo") in RStudio or in R console outside RStudio. My compiler is clang4, and I have no problem installing RcppParallel or compiling my own Rcpp code that uses RcppArmadillo and RcppParallel. R version: 3.5.0, MacOS High Sierra.
Edit: I looked at https://github.com/RcppCore/RcppArmadillo/issues/143, which is very relevant. I did install clang6 and gfortran 6.1, both downloaded from the CRAN website. I also changed the .R/Makevars file to reflect the changes to clang6. I have also installed ccache as suggested, to make compilation faster. Here's my Makevars:
F77 = /usr/local/gfortran/bin/gfortran
FC = $F77
FLIBS=-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin16/6.3.0 -L/usr/local/gfortran/lib -lgfortran -lquadmath -lm
CC=ccache /usr/local/clang6/bin/clang
SHLIB_CXXLD=ccache /usr/local/clang6/bin/clang++
CXX= ccache /usr/local/clang6/bin/clang++ -Wall

CXX14= ccache /usr/local/clang6/bin/clang++
CXX17= ccache /usr/local/clang6/bin/clang++
LDFLAGS=-L/usr/local/clang6/lib
From the outputs in the R console when I was installing the package (added to the error message above), I can tell that clang6 was used for compilation. I also found the downloaded RcppArmadillo tarball, unpacked it, and ran ./configure from the command line. Nothing seemed wrong there; no config.log file was generated. This doesn't seem to be a configuration problem. Then I still got the exact same error when trying to install the package in R, after configuration, in libs. I also didn't get any message about -fopenmp. It seems that my problem is a bit different from that in the GitHub ticket.
R 3.5.x requires clang6 and adding clang6 to your system PATH variable.
Steps:
x Download and install the clang-6.0.0.pkg official package from CRAN.
x Delete your ~/.R/Makevars as it is likely set to use clang4. To do this, open Terminal and type:
sudo rm ~/.R/Makevars
x Then add to your ~/.bash_profile the following:
if [ -d "/usr/local/clang6/bin" ] ; then
export PATH="/usr/local/clang6/bin:$PATH"
fi
Note: If you are using a shell other than bash you will need to add the above into the appropriate file, e.g. for zsh add to ~/.zshrc, as this was not implemented in the official installer.
I should have a few cycles to finish writing a new unofficial Rtools installer a bit later. See: https://github.com/coatless/r-macos-rtools/issues/7
Note: Alternatively, you can remove the paths individual with
sudo vi ~/.R/Makevars
Pressing I to enter insert mode, deleting lines with clang4 in the path, and then pressing ESC + :wq to write changes to file.
Never mind, this problem went away with version 0.8.600. Later, this problem appeared again when I upgraded to RcppArmadillo 0.9.100.5.0. Somehow I only got this error when building from source; I downloaded the binary manually from the CRAN website, and used R CMD INSTALL to install the prebuilt version, and it worked; somehow R doesn't seem to know that there is a binary available for the newest version.
I did install clang6 and modified .R/Makevars to use clang6, but the same problem persisted; probably something else caused the problem.

Why is Rpy2 not installing in my OSX Sierra terminal?

I have seen a number of different people post this problem (example: Tried to guess R's HOME but no R command in the PATH. OsX 10.6 and Installing rpy2 on Mac OSX 10.8.5), but I have yet to find a viable solution.
I have ensured that I have Python-2.7 installed in my terminal, and since I had recently upgraded by RStudio, I thought that my R was also updated. But everytime I tried to run either:
pip install rpy2
or
easy_install rpy2
I kept getting the same error of Error: Tried to guess R's HOME but no command 'R' in the PATH.
After some googling, I decided to try to download the latest version of R (v 3.4.1), even though I'm very certain it was already updated to begin with. But now I get the following behemoth of an error (I should note that I have condensed it):
In file included from ./rpy/rinterface/_rinterface.c:122:

So now I have a completely different error occurring. I thought that upgrading my R would automatically add it to my environmental variable PATH, but now I'm really at a loss at how to deal with this. I have tried to google this new error but I can't seem to find any solutions that are geared towards installing Rpy2 on a Mac OSX with Python-2.7 and R-3.4. Can anybody offer any kind of advice?
ADDENDUM
I have now tried a variety of other approaches, including downloading XCODE, and updating my GCC compiler, (one such approach is delineated in http://cs.millersville.edu/~gzoppetti/InstallingGccMac.html), and I have also tried to reinstall GCC with the command brew reinstall gcc --without-multilib. I have also edited my PATH environmental variables to include R, CC, and have still had no luck.
I have now figured out that rpy2 installation is contingent upon the right kind of compiler being used. The default compiler for Apple is clang, which does not support rpy2's set up process. So, after acquiring the gcc compiler via homebrew, you can then run brew ls gcc to see the file paths of what gcc compilers are present on your computer. I then ran the following commands in the terminal to change the default compiler from clang to the file path gcc-7, then set the proper flags (which I deduced from reading the error messages yielded by the compiler before), and then install rpy2.
export CC=/usr/local/Cellar/gcc/7.2.0/bin/x86_64-apple-darwin16.7.0-gcc-7
export CFLAGS="-W"
pip install rpy2==2.8.6
I should note that I installed rpy2 version 2.8.6 since my scripts are in Python 2.7, and rpy2 2.9.0 is only compatible with Python 3.x. Furthermore, I am aware that this answer might not adequately describe the problem for everyone, so I encourage other users to expand and/or correct this solution.
The error about "no R in the PATH" is exactly about what it says. To reproduce, open a terminal and enter "R": there should not be any such command found. The solution is to have R findable in the PATH.
Now starting with R-3.4 the tools needed to compile R and and R extensions in C have changed, and the requirements are less standard than one might hope for. This can be debated to be an issue with R and OS X, and there is an open issue in the rpy2 tracker about it.
edit: Note that the issue was resolved and a precompiled binary wheel for rpy2-2.9.3 is now available on pypi.
It's possible to do the GCC switch with a single env command:
env CC=/usr/local/Cellar/gcc/7.2.0/bin/gcc-7 pip install rpy2
The reason clang doesn't work with RPy2 is because clang 4.0.0 doesn't include the -fopenmp flag, which is used by R. There's an ongoing open problem thread on the RPy2 Bitbucket about it.

Install Rmpi on Centos fails with "can't find -lmpi"

I have mpi running on a cluster. It works fine for executables, as well as C programs; so I am pretty sure it works fine. However, when I am trying to install Rmpi, I get an error.
Architecture:
Centos 6.4
MPICH 3.0.3 (had the same problem with 1.4).
R 2.15
Rmpi 0.6-3
I tried different combinations. Specifically, tried to run install.packages() from inside R, and R CMD INSTALL from command line. I tried sudo, su -, and even install into non-privileged "private" directory (in case setting LD_LIBRARY_PATH screws things up). So, here is an example of what I ran:
export LD_LIBRARY_PATH=/opt/tmp/shared/mpich2-install/lib/
install.packages("Rmpi", configure.args = c("--with-Rmpi-include=/opt/tmp/shared/mpich2-install/include/", "--with-Rmpi-libpath=/opt/tmp/shared/mpich2-install/lib/", "--with-Rmpi-type=OPENMPI", "--with-mpi=/opt/tmp/shared/mpich2-install/"))
In every event I get consistent error:
gcc -m64 -std=gnu99 -shared -L/usr/local/lib64 -o Rmpi.so RegQuery.o Rmpi.o conversion.o internal.o -L/opt/tmp/shared/mpich2-install/lib/ -lmpi -L/usr/lib64/R/lib -lR
/usr/bin/ld: cannot find -lmpi
collect2: ld returned 1 exit status
Note, that if I put mpi-type as MPICH (instead of OPENMPI) I get an error about bad format.
I ran out of ideas... There is a similar post, but my problem seems different. Thanks.
Apparently, this is a known incompatibility between MPICH and Rmpi. I installed Open MPI and everything worked just fine. Maybe, it will help somebody as well...

/usr/bin/ld: cannot find -lfreetype qt

Compiling on Fedora 10.
I am using qt for the first time. I started by creating a simple GUI application with all the default settings. When I tried to build the project I got the following error messages.
However, when I did a search for -lfreetype I found it in the following directory.
/usr/lib/libfreetype.so.6
/usr/lib/libfreetype.so.6.3.18
Is there anyway to resolve this issue?
Many thanks for any advice

When executing build step 'Make'
You have to install the freetype-devel package. The devel package contains the header files which in the case of freetype shoud be located at: /usr/include/freetype.
I had the same problem on Ubuntu 8.10, QT 4.5. I "fixed" it with the following bizarre hack:
After the build fails, rename the QT lib directory to something else - e.g. "mv ../../qtsdk-2009.01/qt/lib ../../qtsdk-2009.01/qt/lib2"
Run "make" again, and it will fail again.
Restore the lib directory
Run "make" again, and now it works.
I have no idea why this happens.
Install freetype1-dev libgtk2.0-dev
and it will compile ok.
On Ubuntu 9.04, installing freetype1-dev & libgtk2.0-dev solves this problem.
But to surprise everyone the hack mentioned by Ross also works, I would really like to know how and why.. M looking into the source code of QTcreator to see if i can find out the reason why. If any one already know the reason, please let me know.
Thanks..
Just installed a newly fresh ubuntu 9.04 (dell D820)- installed qt creator nothing else - same problem
use option from S R that works because it needs libgtk2.0-dev (this will also load freetype6 ) installed from package manager.
Same effect you will see if you also install qt designer from package manager (it will install all the right packages
regards
Nico
I had same problems with Elive, freetype1-dev and libgtk2.0-dev and for the /usr/bin/ld: cannot find -lSM thing xorg-dev fixed the problem.
The first thing you have to make sure is that you have libfreetype.so installed in your computer. Use the command 'locate libfreetype.so', and you may find there is a '/usr/lib/libfreetype.so.6' in the result. The compile software can't identify libfreetype.so.6 as a shared library, so, you have to make a symbolic link to the target. Use the command 'ln -s /usr/lib/libfreetype.so.6 /usr/lib/libfreetype.so', when you compile the program again, you will find the error had gone. You can also solve the errors likely. Good Luck!
