I do not succeed to install CPLEX (version 22.1.1) on a MacBook with M1 chip (macOS Ventura - 13.1).
The installer keeps installing the files for the wrong architecture, i.e., x86_64 instead of arm64.
/Applications/CPLEX_Studio2211/cplex/bin/x86-64_osx
When I try to use the Python API, I get an error containing the following message:
(mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64'))
Using the C++ API, a similar error occurs:
building for macOS-arm64 but attempting to link with file built for macOS-x86_64
uname -m in the used terminal yields arm64
The installer is a Java-Application though. So I created a Java- Programm to see what architecture Java returns, and
System.out.println(System.getProperty("os.arch"));
returns x86_64.
So my guess is that this is the underlying issue.
Edit: I removed all java installations - just to make sure the installer can't use any existing installation, but the installer installs its own JRE anyways. I executed the installer again, and the same issue occurs. What's strange is that I can actually solve a model in OPL without problems.
Seems like IBM has added support for the new architecture, but not tested it properly.
