Source: pari Version: 2.13.0-2 Severity: wishlist Tags: patch User: debian-cr...@lists.debian.org Usertags: ftcbfs
PARI fails to cross build due to using 'cc' as the C compiler: http://crossqa.debian.net/src/pari With the attached patch, PARI successfully builds and the cross tests (by way of QEMU user mode emulation) pass as well building for arm64. This also adds support for the standard nocheck DEB_BUILD_OPTION. What the origin Makefile syntax does is that, if CC is unset by the user and is Make's implicit default, then it gets overridden with the appropriate cross-compiler. This is the recommended solution [1] and has the bonus of letting users override the compiler at build time should they please.
