Source: perl Version: 5.40.1-4 Severity: normal Tags: patch User: [email protected] Usertags: ftcbfs
The upstream changes for CVE-2025-40909 introduced a new Configure variable `d_fdopendir`. Unfortunately this broke cross builds as seen at http://crossqa.debian.net/src/perl because I didn't think of updating the bundled support files [1]. A minimal fix is to add d_fdopendir='define' to the config.sh.static files under debian/cross/, as in the attached patch. Some of those files are outdated as the architectures are not built on the buildds anymore etc., but it seems easiest to update them all for this. The extra variable should not hurt in any case. I have tested that this fixes cross building an armhf package on amd64. I'll try to get this in trixie if it's not too late. The files in debian/cross are not used for anything during native builds, so the risk of regressions is very low. [1] Building Perl currently requires running native probes with the Configure script. Fixing this to support cross builds is not trivial. So we work around it by bundling the configuration information from native builds in the source package, and using those for cross building. While this is far from the desired goal of full cross build support, the approach at least keeps the rest of the machinery working. See debian/cross/README for more information. -- Niko Tyni [email protected]
