Package: gcl Version: 2.6.12-32 Severity: normal Tags: patch User: ubuntu-de...@lists.ubuntu.com Usertags: origin-ubuntu yakkety ubuntu-patch
In Ubuntu, the attached patch was applied to achieve the following: * Set CC to 'gcc -fno-pie -no-pie' to prevent FTBFS (LP: #1557236) The patch itself should be self-explanatory. In Ubuntu, we now default to '-fPIE -pie' on amd64, ppc64el, and s390x. Turns out that gcl, when compiled with -fPIE breaks rather spectacularly. This patch should be a no-op for Debian, but it's good future-proofing against a time when Debian may choose to change their defaults as well.
