Thanks for the testing! This error seems to be difficult to reproduce since it is a makefile dependency problem. I think appending loongarch-multilib.h to $(GTM_H) instead of $(TM_H) could help. > And when this is fixed, it might be a nice idea to have a > --with-multilib-list config in ./contrib/config-list.mk . Thanks, will add this later too. P.S. Currently support for "f32" is not active, and it should probably be avoided if you want to build a working rootfs. Yujie
