Failure to build example on mac M1 #404

Open matthagan15 opened 1 month ago

matthagan15 commented 1 month ago

I'm trying to build the matmul.c example on a mac m1 using the Macaulay2 tap. I managed to figure out the linking issues and get g++ to find the appropriate libraries and headers, but once I get that figured out I run into a massive linker error which has the last two lines 

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation).

the build command I ran to get this was gcc -o out main.cxx -L/opt/homebrew/lib -I/opt/homebrew/include -std=c++11. I've included the full error in error.txt. If anyone knows of anyway around this I would gladly appreciate it!

Unfortunately, looking at Macaulay2 on GitHub shows that Mac M1 is not supported for the provided home-brew tap (see https://github.com/Macaulay2/homebrew-tap/wiki/M2-on-M1).

Your problem is coming from the fact that LinBox/fflas-ffpack have dependency with Givaro library that need to be build for arm64, which is not provided with Macaulay2 tap. You can try to install Givaro on your own from the GitHub repo (https://github.com/linbox-team/givaro) but it would be preferable to build the whole LinBox/fflas-ffpack from their sources (you will get more optimized code).

I appreciate it. Unfortunately it looks like I can't build givaro on arm64 as I run into perl dependency issues and there does not appear to be standardized ways to downgrade the version of perl through homebrew. I went through and tried to upgrade the build scripts for givaro manually to use the version of perl provided through homebrew but the errors kept getting worse so I stopped.
