I try to install Corrfunc on macos Big sur. With all dependencies installed, after git clone and make install, I get the following error:

MacBook-Pro:Corrfunc $ make install
mkdir -p lib
/Applications/Xcode.app/Contents/Developer/usr/bin/make -C theory install

I guess the problem is the library should be libomp5, instead of liomp5? But I couldn't find where to change it so couldn't confirm this. Any comment would be very helpful.

@manodeep I'll leave this to you as I'm pretty useless at Mac!

@ziarriall I've lightly edited your comment for formatting

[manodeep]

Ohh crap - totally missed this one!

@ziarriall Did you manage to find a work-around?

[manodeep]

I have not encountered clang-omp in quite a few years now - but these are the two relevant lines that would need to be commented out/changed

[ziarriall]

Sorry for the late reply. I changed the line 267 to -Lmypathtolib -lomp, now it works. Thanks a lot.

Looks like this was resolved
