[isabelle-dev] Isabelle component csdp-6.x is 32-Bit [macOS]

Now here is something weird: while the SOS method definitely fails on my Catalina MacBook Pro at home, it succeeds on my Catalina iMac at work.

I was also able to compile Csdp-6.1.1 from sources this morning. It seems to require nothing but a prior installation of GCC including Fortran.

What now? Shall we ask the general mailing list? I have seen no complaints of SOS failing, but then again, it’s extremely obscure.
