Source: nettle
Version: 2.4-3
Severity: wishlist
User: debian-...@lists.debian.org
Usertags: port-x32 ftbfs-x32
Here's the interim patch I'm currently using to build nettle on the unofficial
Debian x32 port. Two issues it addresses:
- The camellia test fails. I'm currently working around this by passing
--disable-assembler to configure on x32.
- The des-compat test segfaults. It turns out compiling with -O1 instead of -
O2 fixes this, so this might be a compiler bug with the version of gcc I'm
currently using. Since it's closely related to the i386/amd64 target, it's
entirely possible that this might hit on i386 and/or amd64 as well with gcc
4.7.2-18 (or -19) from experimental. I haven't checked.
So, I'm currently not tagging this as "patch" since you probably wouldn't want
to include the -O2 -> -O1 part in a general Debian upload.
