Fail installation of CAMB #97

Closed rickypang0219 closed 3 years ago

rickypang0219 commented 3 years ago

Hi, everyone. I am a student doing research on cosmology and astrophysics and I need to use camb. However, I cannot install camb in my MacBook with python (ver. 3.9.1) . Below is the response of terminal while installing camb. May I ask how to deal with the current problem in order to install camb successfully. Thank you. Besides, I apologise for pasting the whole terminal output in here.

Thank you for your comment, Alexander-mead. I have looked to #96 and I installed forutils (ver.0.1) via git. However, I still cannot download the camb.

I saw the same ld: library not found for -lSystem error after recently updating my Mac OS to v11 (big Sur) and updating to gfortran 10.2. I installed gfortran via homebrew using brew install gcc, but then saw the same error whenever I tried to compile *any*Fortrancode, not justCAMB`.

I was able to solve the problem using brew install gfortran, in addition to brew install gcc, but I don't know why this works.

Thank you, Alexander-mead. This method perfectly works fine for me.

Just a note @alexander-mead that apparently this is because in Big Sur they moved the library locations. See e.g. this issue https://github.com/ponylang/ponyc/issues/3684 for a solution!
