Compiling with gcc fails

[baerbock]

I've prepared it with CC=gcc cmake .. -DCMAKE_INSTALL_PREFIX=/usr

Thanks for reporting this. Apparently our cmake build is out of date. I'll work on it, but probably not until after the first of the year.

I am having trouble reproducing this issue. Can you provide the full outputs of your cmake and the make VERBOSE=1 commands?

[baerbock]

@khsa1 I was able to fix the compilation. SETSM seems to

• need OpenMP
• need empty CFLAGS / CXXFLAGS
• need gcc manually set with CC=gcc

I wish you a Merry Christmas and will investigate default.txt in the new year!
And I'm very sorry if I've wrongly guessed your religion, Самуил Хувис.

@baerbock Yes, you will need OpenMP to compile the code, but I am surprised that you needed empty CFLAGS/CXXFLAGS and CC=gcc.

I was able to reproduce the issue with a non-empty CFLAGS or CXXFLAGS and will look into it. But I can compile without manually setting CC=gcc. I would appreciate any additional information or log files you can provide to help debug this.

No problem, have a merry Christmas.
