I want to compile an R package with specific linker flags. In my case, I want to use -rpath to "hard code" some library paths for the package so I don't have to have them always in my LD_LIBRARY_PATH.
If I simply try to do so using R's environment variables, it seems to have no effect:
Sys.setenv(LDFLAGS="-Wl,-rpath,/stornext/System/data/tools/proj/proj-4.9.3/lib -Wl,-rpath,/stornext/System/data/apps/geos/geos-3.7.0/lib")
install.packages("sf")
The final gcc invocation is:
/stornext/System/data/apps/gcc/gcc-11.1.0/bin/g++ -std=gnu++11 -shared -L/stornext/System/data/apps/R/R-4.2.1/lib64/R/lib -L/usr/local/lib64 -o sf.so RcppExports.o bbox.o gdal.o gdal_geom.o gdal_read.o gdal_utils.o gdal_write.o geos.o hex.o mdim.o ops.o polygonize.o proj.o proj_info.o raster2sf.o sfc-sfg.o signed_area.o stars.o wkb.o zm_range.o -L/stornext/System/data/tools/proj/proj-4.9.3/lib -lproj -L/stornext/System/data/tools/gdal/gdal-2.4.4/lib -lgdal -L/stornext/System/data/apps/geos/geos-3.7.0/lib -lgeos_c -L/stornext/System/data/apps/R/R-4.2.1/lib64/R/lib -lR
And when I check the final .so file with readelf -d, I can see that the RPATH headers are missing.
If I try to add them via configure, that doesn't work either:
install.packages("sf", configure.vars="LDFLAGS=-Wl,-rpath,/stornext/System/data/tools/proj/proj-4.9.3/lib -Wl,-rpath,/stornext/System/data/apps/geos/geos-3.7.0/lib -Wl,-rpath,/stornext/System/data/tools/gdal/gdal-2.4.4/lib")
This gives me:
sh: -Wl,-rpath,/stornext/System/data/apps/geos/geos-3.7.0/lib: No such file or directory
In this case, the flags are being passed through numerous stages in order to finally get to the makefile: they go from R to R CMD INSTALL in the shell, then to the configure script, so escaping quotes and spaces seems incredibly difficult here.
Can anyone offer help as to how to provide multiple linker flags when compiling an R package?
I can’t figure out how to give my R package’s shared library’s debug symbols source line information. What am I missing?
I create the following src/Makevars file:
PKG_CXXFLAGS=-O0 -ggdb
PKG_LIBS=-O0 -ggdb
I compile the package using R CMD INSTALL --no-multiarch --with-keep.source:
* installing to library ‘~/.local/lib/R/3.6’
* installing *source* package ‘reticulate’ ...

installing to ~/.local/lib/R/3.6/00LOCK-reticulate/00new/reticulate/libs
I debug like this:

Why does my function not have line numbers even though I specified -ggdb in both compilation? I see that only RcppExports.cpp is mentioned in the command line, is that the problem? If so, how can I change this?
Changing the Makevars doesn’t prompt recompilation.
I needed to rm -f src/*.o src/*.so before the object files get recompiled.
This is specifically for Windows. The simplest way to do it is to set the R_MAKEVARS_USER environment to point to the Makevars.win file. That seems to work. However, debug break points have stopped working!!!!
Since I installed Catalina, any attempt to compile an R package fails. My system is set up to use home-brew. The failure messages look like this:
/usr/local/clang8/bin/clang -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -I../inst/include -I/usr/local/clang8/include -I/usr/local/Cellar/gcc/8.3.0_2/include -fopenmp -fPIC -Wall -g -O2 -c R_register_native.c -o R_register_native.o
In file included from R_register_native.c:1:
/Library/Frameworks/R.framework/Resources/include/R.h:55:11: fatal error: 'stdlib.h' file not found
# include <stdlib.h> /* Not used by R itself, but widely assumed in packages */
After googling I found this link in the home-brew site on GitHub. I can't follow much of the discussion but it seems that Apple removed the usr/include directory and that the home-brew folks are looking for a solution. I don't immediately have a need to compile these packages so my plan is to wait until home-brew finds a solution. But if there is an easy one now, please share.
After some additional searching I found this link with a bunch of discussion about this problem, a lot of which I didn't understand. But this bit of code seemed promising.
sudo ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/* /usr/local/include/
I ran it, rebooted my mac, opened RStudio and got the list of new package updates. Ran the update, answering yes to compile. Lots of messages and some warnings but at the end of it all, there were no errors. But all the messages start with something like
/usr/local/clang8/bin/clang -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -I../inst/include -I/usr/local/clang8/include -I/usr/local/Cellar/gcc/8.3.0_2/include -fopenmp -fPIC -Wall -g -O2 -c R_register_native.c -o R_register_native.o
When I cd into /usr/local/clang8/bin and get the version of clang it is Apple clang version 11.0.0. Also clang symlinks to clang-8 and clang++ symlinks to clang
The contents of /usr/local/Cellar/gcc is a directory called 9.2.0_1. When I go to /usr/bin and run gcc --version I get messages about this being Apple clang version 11.0.0. It seems like R is compiling using the Apple clang version. Is that a problem? Is there some way to move everything to using the brew version of clang? FYI, here's my current path - /usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Library/Apple/bin:/Library/TeX/texbin:/opt/X11/bin:/usr/local/CrossPack-AVR/bin:/usr/local/git/bin

I don't have /usr/local/lib/gcc/x86_64-apple-darwin13.0.0, so it makes sense that it can't be found. I have /usr/local/lib/gcc/i686-apple-darwin11 and /usr/local/lib/gcc/4.8 (symlink to Homebrew installation). Where is it getting x86_64-apple-darwin13.0.0 from?
There are a lot of references to a similar error online. However, all of them are related to compiling in Xcode and resolved by updating project settings, which is not applicable here.
You need to modify the ~/.R/Makevars file. For a greater overview of this see: https://cran.r-project.org/doc/manuals/r-release/R-admin.html#OS-X-packages
Alternatively, this has been answered before in a bit more depth by #kevin-ushey in Rcpp warning: "directory not found for option '-L/usr/local/Cellar/gfortran/4.8.2/gfortran'".
What is happening is your code is not being run under gcc instead it is being forwarded to clang
You will need to change your compile statements in ~/.R/Makevars/ to gcc using:
VER=-5.3.0
CC=gcc$(VER)
CXX=g++$(VER)
CFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
CXXFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
FLIBS=-L/usr/local/Cellar/gcc/5.3.0/lib/gcc/5
This assumes you have already installed gcc via homebrew under:
brew install gcc
(gfortran ships with gcc in brew now)
Incorporating previous solutions with additional help from the comments, the following solution has worked for me on Mac OS X High Sierra.
Create/edit ~/.R/Makevars with the following contents:
VER=-8
CC=gcc$(VER)
CXX=g++$(VER)
CXX11=g++$(VER)
CXX14=g++$(VER)
CXX17=g++$(VER)
CFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
CXXFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
FLIBS=-L/usr/local/Cellar/gcc/8.2.0/lib/gcc/8
Note, I am using homebrew and have gcc version 8.2.0 installed.
From http://thecoatlessprofessor.com/programming/rcpp-rcpparmadillo-and-os-x-mavericks-lgfortran-and-lquadmath-error/ you can fix this by downloading the optional gfortran libraries from http://r.research.att.com/libs/ and extracting them. To do this on the command line
curl -O http://r.research.att.com/libs/gfortran-4.8.2-darwin13.tar.bz2
sudo tar fvxz gfortran-4.8.2-darwin13.tar.bz2 -C /
I had this issue for a long time, working on a Mac. Following the other answers on this page and other questions, I did the following and it finally worked!
Step 1 - brew install gcc (it installed gcc-11 for me. If this is different for you in the future, replace gcc-11 below with the corresponding version. You can find the version by checking in the folder /usr/local/bin and seeing the latest gcc version file there)
Step 2 - xcode-select --install (this installs Xcode CLI)
Step 3 - ln -sf /usr/local/bin/gcc-11 /usr/local/bin/gcc (this makes a new gcc symlink under /usr/local/bin/. Source)
Step 4 - I did not have a ~/.R/Makevars file. Heck, I didn't even have the ~./R folder. Made the folder and the file. Here is what I wrote in the Makevars file (remember to change the GCC version in the first and last line according to the version you have. Also remember to not have the entire version number that's in the last line, in the first line. Just the overall version number - 11 in my case) -
VER=-11
CC=gcc$(VER)
CXX=g++$(VER)
CXX11=g++$(VER)
CXX14=g++$(VER)
CXX17=g++$(VER)
CFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
CXXFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
FLIBS=-L/usr/local/Cellar/gcc/11.2.0_3/lib/gcc/11
Now restart, and voila! It works.
I'm working on MacOS Mojave (10.14.5) and on R 4.0.0. The problem here is that "CRAN R 4.0.0 builds and higher no longer use any custom compilers" (see here), so the Makevars solution does not appear to work anymore.
The solution for me was to download and install the GNU Fortran compiler from the official R-Project website. Note that you will also need Xcode and Xcode command-line tools.
After running the installer with default settings, compilation of gfortran code worked without problems.
I received the same error on MAC. All I needed to do was to install gfortran-6.1.pkg from https://cran.r-project.org/bin/macosx/tools/. Make sure that the package is installed under /usr/local/gfortran so it can be found by R.
Alternatively you can install it via homebrew typing brew cask install gfortran in the terminal (it may ask for your password).
In my case I combined this answer with this one, to produce the following code in the ~./R/.Makevars-file.
touch ~./R/.Makevars
(because it didn't exist there)
open -a BBEdit ~./R/.Makevars
(I use BBEdit as text editor)
Added the following lines to the Makevars-file:
VER=-11
CC=gcc$(VER)
CXX=g++$(VER)
CFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
CXXFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
# FLIBS=-L/usr/local/Cellar/gcc/11.1.0_1/lib/gcc/11
# FLIBS = -L`gfortran -print-file-name=libgfortran.dylib | xargs dirname`
FLIBS=`gfortran -print-search-dirs | grep ^libraries: | sed 's|libraries: =||' | sed 's|:| -L|g' | sed 's|^|-L|'`
These two lines were suggested by #KevinUshy.
# FLIBS=-L/usr/local/Cellar/gcc/11.1.0_1/lib/gcc/11
# FLIBS = -L`gfortran -print-file-name=libgfortran.dylib | xargs dirname`
I commented these out, as I figure that the final line would probably work best.
Two notes.
I have brew installed and I used brew to install gcc using the command brew install gcc.
I figure out the version-naming using brew info gcc, which gave me 11.1.0_1, but it is linked as gcc-11, so VER=-11 in the .Makevars-file.
Hope this helps others.
I am having Mac OS Catalina and in my case installation of Homebrew, the newest gcc and Gfortran 8.2.0 solved the issue.
The solution was to re-install problematic packages with Homebrew.
$ brew uninstall --ignore-dependencies --force openssl
$ brew install openssl
$ brew uninstall --ignore-dependencies --force readline
$ brew install readline
Digging this topic, if you tried these and much others approaches related to this error and got no success, I strongly recommend you to check if your OSx - just in case - deleted the .zshrc file.
If that's the case, you should create again this file in the root dir. type in your terminal:
touch .zshrc
followed by
openssl_prefix=$(brew --prefix openssl) printf "CFLAGS=-I$openssl_prefix/include \nLDFLAGS=-L$openssl_prefix/lib"
example of output:
CFLAGS=-I/usr/local/opt/openssl#3/include LDFLAGS=-L/usr/local/opt/openssl#3/lib
add them to the zshrcfile content, run
source .zshrc
to refresh the file and that`s all!
Had this problem using R on macos 12.4. It was caused by old and stale entries in my ~/.R/Makevars file. Once I commented everything out everything compiled just fine. I have XCode and brew install gcc active.
For later versions of R (R 4.0 and higher) and later operating systems, the recommended fix for this problem seems to be to install gfortran via rtools (see here, already mentioned in the answer of #lks_swrx).
When following these instructions, I ran into an additional problem, since my computer uses Apple Silicon chips (not Intel anymore), for which I wanted to add a solution here:
Download the appropriate gfortran tarball from rtools
Run tar fxz gfortran-12.0.1-20220312-is-darwin20-arm64.tar.xz -C /
Add it to your path by adding this line to your .zshrc file:
nano .zshrc (or whatever you use as text editor)
export PATH=$PATH:/opt/R/arm64/gfortran/bin
So far, so good; but the installation of DESeq2, which brought me here, did still not work, because R could not find the library. This is the fix:
Create a symlink to the gfortran library in /usr/local, so that R can find it:
ln -s /opt/R/arm64/gfortran /usr/local/gfortran (might require sudo)
