I am trying to install Concorde linked with QSOPT following these instructions. Regarding QSOPT, I downloaded files from section Intel MacOS 10.6 (64-Bit). But, as I have Apple M1 chip, it does not work. I think that the problem is in the arm64 architecture in terms of QS, however with other more commercial software for Intel processor, I do not face any issue thanks to Rosetta.

The error I am facing when I run

./configure --host=darwin --with-qsopt=fullpath/QS


ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [concorde] Error 1

Thanks to the support of Bill Cook, it is now available a version of qsopt.a for the M1 Apple Chip on the QSOPT download page. This perfectly worked for me by run

./configure --host=darwin --with-qsopt=fullpath/QS
