Unable to load HSL solvers for IPOPT on M1 Mac #1494
Description
I am trying to get IPOPT with the HSL solvers on my Mac (M1 chip), but the library for the HSL solvers is missing. If I try to specify an HSL solver like ma27, I get the following:
Exception of type: OPTION_INVALID in file "IpAlgBuilder.cpp" at line 268:
Exception message: Selected linear solver MA27 not available.
Tried to obtain MA27 from shared library "libhsl.dylib", but the following error occured:
