Created attachment 83908 [details] Failed compilation of systemd with error: redefinition of 'struct ia64_fpreg' Hello, Trying to compile systemd-201, 204 or 206-r1 on Gentoo ia64 Linux all fail with error: redefinition of 'struct ia64_fpreg' in src/core/execute.c. Originally reported in Gentoo bug tracker [1], I was asked to report upstream [2][3]. I've checked that this error is also present in upstream code. I've bisected it to commit 8351ceaea9480d9c2979aa2ff0f4982cfdfef58d (execute: support syscall filtering using seccomp filters). Complete build log attached. Please let me know if I can help further. Thanks, Émeric [1] https://bugs.gentoo.org/show_bug.cgi?id=480218 [2] https://bugs.gentoo.org/show_bug.cgi?id=480218#c4 [3] https://bugs.gentoo.org/show_bug.cgi?id=480218#c5
It's looks like a bug in kernel headers and/or glibc headers. It would be best if you could investigate which of those two is broken, and file the bug there.

You need to take the full list of #includes, and remove them step by step until you find the minimal set that reproduces the error.

Do you think the same systemd source code could successfully compile with a different version of kernel or glibc? I'm asking this, because it appears that Debian successfully built systemd-204 for ia64 [1][2].

You're absolutely right, this has nothing to do with systemd. I just successfully compiled systemd-204 on a Debian ia64 system. Bu contrast, the exact same systemd-204 source code fails to compile on Gentoo ia64 with error: redefinition of 'struct ia64_fpreg'. Googling a little bit, I found this 10-year old bug reported against glibc [1]. This explain why systemd compiles fine on Debian: eglibc is shipped rather than glibc. Sorry for the noise, closing bug. Émeric [1] http://sourceware.org/bugzilla/show_bug.cgi?id=762
Until glibc is fixed, maybe a workaround like the following (currently needed for "audit") could be used in systemd to allow its compilation on ia64 (since looks like glibc bug is there for really a long time without solution): http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-process/audit/files/audit-2.1.3-ia64-compile-fix.patch?view=markup
