Good afternoon

I'm having a lot of troubles installing OpenFOAM 5.x in a server with CentOS 7.6 where I don't have root access.

I tried following the instructions of wyldckat in his forum

http://openfoamwiki.net/index.php/In...7.4_.281708.29

but I can't complete the build of Gcc 4.8.5 in step 11.

At the end of the log file I have the following:

rm gcc.pod
make[3]: Leaving directory `/home/users/p/a/palarcon/OpenFOAM/ThirdParty-5.x/build/linux64/gcc-4.8.5/gcc'
make[2]: *** [all-stage1-gcc] Error 2
make[2]: Leaving directory `/home/users/p/a/palarcon/OpenFOAM/ThirdParty-5.x/build/linux64/gcc-4.8.5'
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/home/users/p/a/palarcon/OpenFOAM/ThirdParty-5.x/build/linux64/gcc-4.8.5'
make: *** [all] Error 2
Error building: gcc-4.8.5

Any idea of what can I do?

Thank you all in advance

Quick question: But the step 11 that you are mentioning is for CentOS 6.9 and not 7.6...

The link you provided should work with CentOS 7.6, although it depends on what's already pre-installed in the system you are using.

Nonetheless, please try first scrolling down to the correct section of the page, namely section "2.2 CentOS 7.4 (1708)" and not using section "2.1 CentOS 6.9".

Sorry for the late replay, but for some unknown reasons the notification email went to the spam folder.

After I posted this question I realized that I was on the wrong section, wo then I started from scratch using the correct section.
Nonetheless the problem persist, mainly due to a problem with a linker

/opt/cecisw/arch/easybuild/2018b/software/binutils/2.30-GCCcore-7.3.0/bin/ld.gold: error: --add-needed is not supported but is required for libopen-rte.so.40 in /opt/cecisw/arch/easybuild/2018b/software/OpenMPI/3.1.1-GCC-7.3.0-2.30/lib/libmpi.so

I looked over the internet and it seems that solving that problem is not "that difficult" if you have root access, because is necessary to change the symbolic link of the gold linker to the bfd one, but in this case I don't have root access.

I contacted the system administrator of my cluster, and they also are having troubles compiling OpenFOAM, they did a first try on friday and didn't work, we will see if today goes better.

Quick answer: Check what the following command gives you:

ls -l /opt/cecisw/arch/easybuild/2018b/software/binutils/2.30-GCCcore-7.3.0/bin/ld*

If it only lists that ld and ld.gold exist, then it is necessary to get another GCC installation...

If ld.bfd is listed in that folder, then... mmm... "-fuse-ld=bfd" can be used... ah, this was already done in OpenFOAM 6 and OpenFOAM-dev...
OK, do the following commands with the OpenFOAM 5.x environment active:

foam
wget https://github.com/OpenFOAM/OpenFOAM-dev/commit/5e8593c1716490a4e74fe8136c248257123aa255.patch
patch -p1 < 5e8593c1716490a4e74fe8136c248257123aa255.patch

This will apply these changes: https://github.com/OpenFOAM/OpenFOAM...248257123aa255

Hopefully it will work as intended from this point onward.

Thank you for your answer, but lucky (and finally) the system administrator was able to install the software.
According to him wasn't "that difficult" so it seems that it took that long only because he didn't have the time to help me with the installation before.
