I was trying to compile an ada program using gnat but I got this error:

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':
array.c:(.text+0x5829): undefined reference to `GOMP_parallel'

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.
I am having the same problem:

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 want to install netgen and try to compile the source code.
During this I got the error message:
U -L/usr/lib/x86_64-linux-gnu -ltk8.6 -ltcl8.6 -lGL -lXmu -lX11 -fopenmp -Wl,-rpath -Wl,/opt/netgen/lib
/usr/bin/ld: cannot find -lXmu
collect2: error: ld returned 1 exit status
make[2]: *** [netgen] Error 1
Maybe I have to install an additional package?
Does anyone have an idea?
You can check, depending on your specific OS, if you are not missing the missing the non-versioned named (i.e. libXmu.so).
Check for ls /usr/lib/libXmu*.*, and if not found, type:
ln -s /usr/lib/libXmu.so libXmu.so.6
ln -s /usr/lib/libXuu.so libXmuu.so.1
If you don't have any libXmu*.* files, then you need to install first libxmu-dev:
sudo apt-get install libxmu-dev
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 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.

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

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...
