Error during compiling ROOTVecOps on ROOT v6.14.04

tcoates3 · September 3, 2018, 10:38am

ROOT Version: 6.14.04
Platform: Scientific Linux 6
Compiler: gcc 4.9.1

I’m trying to install ROOT 6.14.04 on a PC running Scientific Linux 6 as the OS, and having trouble with the compilation of ROOTVecOps. It’s important that I install ROOT on this machine rather than using e.g. lxplus, as it’s a requirement for a piece of software that must also be installed locally. I’m aware that the default versions of cmake and gcc that come with SL6 are too low for compiling ROOT, but I have switched to cmake 3.4.1 and gcc 4.9.1. The output of gcc --version is:

gcc (GCC) 4.9.1 20140922 (Red Hat 4.9.1-10)

and cmake3 --version is:

cmake version 3.4.1

This is the error message given during compilation:

I searched for previous cases of this problem, and found two solutions here and here, neither of which work for me. The line set_property(GLOBAL APPEND PROPERTY ROOT_BUILTIN_TARGETS VDT) is already present in the correct place in cmake/modules/SearchInstalledSoftware.cmake and when I use the command cmake3 --build . --target VDT the terminal responds with only:

Built target VDT

and further attempts at compiling ROOT after this have the same issue as above. What am I missing for compiling this?

Note that your “gcc” compiler must not come from the “devtoolset”.

tcoates3 · September 3, 2018, 10:58am

Thanks for the quick response. Is there any workaround? Almost all resources I can find for installing different versions of gcc on SL6 involve using devtoolset.

Wile_E_Coyote · September 3, 2018, 11:12am

If you have CVMFS, you could try one of the “/cvmfs/sft.cern.ch/lcg/contrib/gcc/” compilers or the “LCG Software Elements”.

So I did manage to solve my problem! Despite the claim that devtoolset won’t work, I managed to compile using it. I had a suspicion it was because of an uncleaned build folder from previous failed attempts with lower versions of gcc, though I was hesitant to try a fresh build because of how long a ROOT build takes. But I created a clean build folder to run a build from scratch using gcc 4.9 and left it running over lunch.

The installation failed on not finding VDT, but I fixed this by going into CMakeCache.txt in the build folder, and editing the line builtin_vdt:BOOL=OFF to ON, then recompiling. This build attempt succeeded and the software I had to install that depended on ROOT also works perfectly.

You will still run into problems if you use anything C++11, like move constructors in std::string or std::chrono etc. But good if if works for you!
