MFiX version 23.3 is available for download. All MFiX users are encouraged to upgrade, especially if you are having compilation issues.
The new version comes bundled with compilers and required DMP infrastructure (except for Windows) and pre-built DMP and SMP solvers are supplied. So unless you have UDFs or chemical reactions, no recompilation is needed for DMP or SMP jobs.
MFiX 23.3 also includes a new stiff chemistry solver, keyword control over floating-point exception handling, and a host of other new features and bug-fixes.
