Bug#588409: perf (linux-tools-2.6.32) fails to build on many architectures
Package: linux-2.6 Version: 2.6.32-16 Severity: serious Justification: fails to build from source perf fails to build for several reasons. 1. Its default CFLAGS include -fstack-protector which isn't available on all architectures. 2. It has a configuration test which relies on linking with an output file of /dev/null, which doesn't work on HP-PA. 3. The perf events feature requires architecture-specific code in the kernel which hasn't been done for all architectures; thus some don't even have a system call number assigned yet. The first two problems are fairly easy to fix. The third will be addressed by restricting the architectures for which perf is built.

Bug#588409: perf (linux-tools-2.6.32) fails to build on many architectures
Regarding the perf tools: Commit 5d7bdab75cd56d2bdc0986ae5546be3b09fea70a upstream should give the -fstack-protector-all test. Regarding the Alpha architecture the following commits that are in v2.6.33 of the kernel upstream provide the performance event interface: Commit fcd14b3203b538dca04a2b065c774c0b57863eec upstream adds the Alpha specific part for perf tools. Commit a582e6f01b90211933e70edcec9bc0bbb1157402 upstream provides minimal support for performance events in the kernel for Alpha. However it probably won't apply cleanly to 2.6.32 without commit 21797c599c710d3851d241c4b50690f2482bf618 which wires up quite a number of missing syscalls, which in turn depends on 6e17e8b9fb74b9fb9f6ea331f7f4a049c5b4c4b8 which wires up the syscall for recvmmsg that is new in 2.6.33. Thus a modified 21797c599 is required for 2.6.32 to do all this; I think I might still have the patch somewhere, but in any case I could regenerate it should you wish to have it.

Thanks; I've applied this and several other upstream build fixes and improvements: perf tools: Display better error messages on missing packages perf tools: Add 'make DEBUG=1' to remove the -O6 cflag perf tools: Test -fstack-protector-all compiler option for inclusion in CFLAGS perf tools: Support static build perf tools: Add V=2 option to help debug config issues perf tools: Suggest static libraries as well perf: Use default compiler mode by default perf tools: Move QUIET_STDERR def to before first use perf tools: Check if /dev/null can be used as the -o gcc argument > Regarding the Alpha architecture the following commits that are in > v2.6.33 of the kernel upstream provide the performance event interface: > > Commit fcd14b3203b538dca04a2b065c774c0b57863eec upstream adds the Alpha > specific part for perf tools. > > Commit a582e6f01b90211933e70edcec9bc0bbb1157402 upstream provides > minimal support for performance events in the kernel for Alpha.

I'll be happy to apply backported patches. However, Alpha is no longer a Debian release architecture and I don't intend to spend any significant time on it.
