Dear Donggyu —
The latest SDK is known to experience a problem compiling MESA 25.12.1. The problem can easily be fixed by removing a few lines of code from mtx/public/mtx_solve_routines.inc — specifically, the lines highlighted in red on this page:
https://github.com/MESAHub/mesa/commit/03ef2a55b0bbd02cb5310d146b5e0ebc8673a0b3
For those that don’t want to modify the code, I recommend downgrading to MESA SDK 25.12.1.
cheers,
Rich
