Trouble with make NJOY21 in Cygwin64 Virtual Linux Environment, Windows 10 OS about njoy21

Hi CK,

Thanks for reaching out. I haven't seen issues like this before, but I also don't have much experience on using NJOY on Windows either.

This looks like a compiler bug. What version of GCC are you using? Do you have access to another compiler or another version on your system?

Thanks,
Nathan

Hello Nathan,

Thanks for getting back to me. And sorry for my slow response. I tried updating GCC and Cygwin to solve the issue, and indeed I am no longer getting the seg fault error. However, I am now faced with a new problem when compiling:

[ 84%] Building CXX object CMakeFiles/njoy21.dir/src/main.cpp.o

This is with the updated version of GCC (9.3.0-2), but I can try previous versions (9.2 or 7.4).

Again, grateful for any and all assistance you are willing to offer.

Cheers,

CK

Hello again Nathan,

Just to follow up, I seem to have successfully installed NJOY2016 in this environment (0 of 55 tests failed in the make test stage). I am not sure if this information is diagnostically helpful, but I thought I would share it anyway.

Cheers,

CK

Thanks for the information. You seem to be getting the same issue as #110, which just came in last night, so it's good to know this is a consistent problem in Cygwin. Using NJOY2016 was my suggested workaround, so you already found that solution.

I'll try to get a Windows machine up and running to see if I can fix the compile flags leading to that problem.

Thanks,
Nathan

Yes I solved this problem. See my updates to #110.

Thanks everybody. I am less savvy than the rest, so I'll stick with NJOY2016 until the Cygwin fixes get implemented. I appreciate all the help!
