(pasting the error line here) - Program received signal SIGILL, Illegal instruction. 0x00007ffff5fddce4 in ffi_closure_alloc () from /usr/lib/libffi.so.6 I really struggle when I have to use gdb, but are you able to list the instruction at that address ? What CPU is this, specifically ? There have been problems in the past with low-end recent intel CPUs where gmp thought an instruction should be available but it wasn't. See the note in 6.17.1 - the configfsf files make gmp do the right thing. I've seen a few invalid opcode messages myself, on Ryzen, probably related to missing instructions (according to gentoo, four were removed in Fam17h but I've no idea *which* instructions) and my problems were in BLFS. ĸen -- This email was written using 100% recycled letters. -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
