Hi all,

After merging the tip tree, today's linux-next build (powerpc64le perf) failed like this:

make[3]: *** No rule to make target '/home/sfr/next/perf/arch/x86/include/generated/asm/syscalls_64.c', needed by '/home/sfr/next/perf/util/syscalltbl.o'. Stop.

(I build in /home/sfr/next/next with objects in /home/sfr/next/perf.)

Presumably caused by commit

1b700c997500 ("perf tools: Build syscall table .c header from kernel's syscall_64.tbl")

I have reverted that commit for today (which fixes my build problem but may not be overall correct).

I'll check, should've been caught by a cross compiler build for ppc64le I have in place :-\

minimal-ubuntu-x-ppc64el: Ok

But maybe not, as this requires audit-libs-devel and that is not present on that minimal ubuntu x-compiler setup, sigh :-\

Hi acme,

I have a jenkins which builds perf on ppc64le, but it only builds Linus' tree and linux-next.

Which branch in your tree should I be building in order to catch problems like this, perf/core ?

https://git.kernel.org/cgit/linux/kernel/git/acme/linux.git/log/?h=perf/core

https://git.kernel.org/cgit/linux/kernel/git/acme/linux.git/log/?h=perf/core

yes, please, I use two normally, one for devel stuff, perf/core, and perf/urgent when sending stuff to the current merge window.

I'll continue trying to get a local, more complete, cross compiler environment, need to look again at how that multiarch stuff is in debian...

I have reverted that commit for today (which fixes my build problem but may not be overall correct).

Right, I'm trying to figure out how to bet fix that, one way would be to do:

--------------------------------------------

Now trying to figure out how to, just for x86 to add a dep for those files, but a arch specific thing shouldn't be in tools/perf/util/Build anyway...

In the end I want this syscalltbl.c thing to know about all arches, to remove the dependency on audit-libs as the way to map syscall ID to name and vice-versa.

So I'll need all arches to generate that arch/$(ARCH)/include/generated/asm/syscalls_64.c file, etc. Doing that by copying from the kernel the files where such info is kept and having a diff check as part of the perf build process, so that we can get notified when it drifts while not tying tools/perf/ to anything outside that can end up breaking the tools/ build when changes happen outside.

Jiri, I think this is enough, i.e. I think we make sure, just like the kernel, that the archheaders target in tools/perf/arch/*/Makefile is called before doing all the other build, no?

I.e. when we get to build syscalltbl.o the syscalls_64.c file will be built already, limited testing seems to agree with this :-)

perf build: Remove x86 references from arch-neutral Build

It will already be dealt with generating the syscalltbl.c file in the x86 arch specific Build files, namely via 'archheaders'.

This fixes the build on !x86 arches, as reported for powerpcle
