I have started using QT on Kubuntu. I first installed g++ via Package Manager. Then I installed QT 5.0.1. I then made a test project to check if everything is correct or not. Then I got following issues.
- cannot find -lGL
- collect2: error:Id returned 1 exit status
I saw in Compile Output

Please help me fix these errors.
Qt != QT
The error tells you what is wrong, the compiler cannot find libGL.so. It's usually in /usr/lib64.

I am trying to compile R in a Redhat linux environment on a HPC cluster. I have used environment modules to install recent versions of a number of tools including GCC 5.2.0. I cannot get R to build from the source. It fails with undefined reference to `GOMP_parallel'. When I compile with the --disable-openmp option it compiles fine.
array.o: In function `do_colsum':

A couple of questions
What are the advantages of having openMP enabled, I am assuming this will enhance the performance?
How do I fix the error I encounter while building? Is this related to linking the correct library? -fopenmp is correctly used while building. libgomp.* files are also in the $LIBRARY_PATH and $LD_LIBRARY_PATH.
It might be a simple thing I am missing, but I have tried to search for a proper answer without success.
Advanced thanks for any help.

Makefile:144: recipe for target 'R.bin' failed
This is a configuration problem from R (autotools problem). My computer has both gcc 4.8 (came with OS) and the latest version gcc 5.2 (I build from source). The gcc 5.2 is located in /usr/local
I saw that R is mixing these two up, and not picking up the 5.2 library locations.
I changed the Makefile (this is only one time fix since the make file is generated by the autotool).
First go to src/main directory. Then edit the Makefile:
143 $(R_binary): $(R_bin_OBJECTS) $(R_bin_DEPENDENCIES)
144 $(MAIN_LINK) -o $# $(R_bin_OBJECTS) $(R_bin_LDADD)
Edite line 144:
144 $(MAIN_LINK) -o $# $(R_bin_OBJECTS) -L/usr/local/lib64 -lgomp $(R_bin_LDADD)
This fixed my problem. I had a hard time filing a bug with the R project. If the R developers saw this, could they fix this at the auto configure level? The auto probing just have to be a little bit smarter.
I am trying to compile the wkhtmltopdf with patched qt using these instructions and when i get to the make && make install it gives me an error has anyone else done this on Ubuntu 14.04? I can't figure out what to do from here.
these are the instructions i am following i know they are not for 14.04 but i hoped they would have worked https://gist.github.com/Zauberfisch/8773593
This is the error i get:

I downloaded a binary from their site that already had the QT build and that fixed the issue for me. Thanks!
I have installed Qt 5.0 (the whole SDK) on Fedora 17. I have configured the compiler (GCC) and everything seems to be working fine, except that when I press "Ctrl-R" for having a demo of my GUI coding, I get the following error :

(The error above is that a file called -lGL is not found)
How do I go about solving this error ?
You will need to have the libGL development files installed. It's been awhile since I used Fedora, but check your package manager for a package named something like mesa-libGL-devel.
I use Xcode 4, and I currently dont have any iDevice right now to be able to test accelerometer in my application, so I googled for a while and find util named "unimotion". read me file for Unimotion says: "A Makefile is included so all you have to do is cd to the 'unimotion' directory and type 'make'." So I tried, but terminal give me a message
ls: /Developer/SDKs: No such file or directory cc -Wall -Os -g
-isysroot /Developer/SDKs/ -arch i386 -arch ppc -fconstant-cfstrings -c -o unimotion.o unimotion.c clang: warning: not using the clang compiler for the 'powerpc' architecture unimotion.c:72:10: fatal
error: 'IOKit/IOKitLib.h' file not found
include IOKit/IOKitLib.h>
1 error generated. make[1]: * [unimotion.o] Error 1 make: * [sub-unimotion] Error 2
again and again.
So, what am I doing wrong?
Thanks.
Rewrite all occurrences of /Developer/SDKs/ in the 3 Makefiles (calibrate/Makefile, motion/Makefile and unimotion/Makefile) with
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
that should help you. If you're using Xcode 4, you'll probably get further error also
llvm-gcc-4.2: error trying to exec '/usr/bin/../llvm-gcc-4.2/bin/powerpc-apple-darwin11-llvm-gcc-4.2': execvp: No such file or directory
as the -arch ppc is not supported there anymore. Just delete every single occurrence of -arch ppc in Makefiles, and it will work.

cannot find -lQtDBus
The QtDBus module is a Unix-only library. In theory it's possible to compile winDBus and then QtDBus for Windows. But it's not easy and I'm not sure about MinGW...
