Created attachment 325325 [details] Add autoconf in %prep Description of problem: During rpmbuild on s390x, ./configure fails with: [snip] checking size of mp_limb_t... 8 configure: error: Oops, mp_limb_t is 64 bits, but the assembler code in this configuration expects 32 bits. You appear to have set $CFLAGS, perhaps you also need to tell GMP the intended ABI, see "ABI and ISA" in the manual. This is solved by adding 'autoconf' in spec in %prep (see attached spec file patch). Version-Release number of selected component (if applicable): gmp-4.2.2-8.fc10
Running autoconf without aclocal and automake can break things. You have to run "aclocal && autoconf && automake -i" or you can use "autoreconf --install --force" which calls all of them and then "libtool --force". And it is more decent to do this in %build then in % prep, since the CPU requirements of these tools are much higher than for unpacking the tarball and applying the patches. Fixed in gmp-4.2.4-2.
