Hello @mlund

Sorry for late reply. Finally, I could install Faunus 2.5.0 using GCC10.3.0 on my Linux machine where I don't have root access. GCC10+ module, which was having problem in gathering some parallel libraries support. This was solved by editing the CMakeLists.txt file. Further, I was getting other errors, which I searched on Google and found that GCC 9 and 10 does not have some library support for TBB, then I disabled it in CMakeLists.txt and tell it to not to search with GCC instead in TBB ../lib directory. This leads to successful building of the Faunus. Two edits in the CMakeLists.txt are shown below:

add_definitions(-D_GLIBCXX_USE_C99_MATH=1)
add_definitions(-D_GLIBCXX_USE_TBB_PAR_BACKEND=0)

In addition to this, let me point out that installation of the Faunus directly from Conda only gives its 2.4.0 version, which does not have OpenMP/TBB parallelization. I don't know why it does not add the latest version.

Thank you

Thanks for posting your solution here; I completely missed this post and only saw it now. This was/is a known problem with some GCC versions that oddly rely on TBB (but do not bundle it). Another trick is to add -DENABLE_OPENMP=false to CMake.
I think the compilation should be smoother on newer compiler and Faunus combinations.
