I think it is set. If I try with explicit ./configure --with-pic to be sure, it still fails. If I try with explicit ./configure --without-pic, I can't build gmp: ``` [...] /usr/lib/gcc/aarch64-unknown-linux-gnu/14/../../../../aarch64-unknown-linux-gnu/bin/ld: mpn/.libs/bdiv_q_1.o: relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `__gmp_binvert_limb_table' which may bind externally can not be used when making a shared object; recompile with -fPIC mpn/.libs/bdiv_q_1.o: in function `__gmpn_bdiv_q_1': ``` with __gmp_binvert_limb_table being the symbol you and Jannik mentioned.. > > Regards, > /Niels best, sam
