A wdotap stage2 cross build from amd64 targeting powerpc with multilib
fails. The tail of the log[1] is:
| : # ppc 64bit build slaps libgcc and libstdc++ to powerpc64-linux-gnu
| mkdir -p debian/tmp/usr/powerpc-linux-gnu/lib64
| cp -a debian/tmp/usr/powerpc64-linux-gnu/lib64/* debian/tmp/usr/powerpc-linux-gnu/lib64/
| cp: cannot stat 'debian/tmp/usr/powerpc64-linux-gnu/lib64/*': No such file or directory
| debian/rules2:2060: recipe for target 'stamps/07-install-stamp' failed
| make[1]: *** [stamps/07-install-stamp] Error 1
| make[1]: Leaving directory '/tmp/buildd/gcc2/gcc-4.9-4.9.2'
| debian/rules:80: recipe for target 'stamps/07-install-stamp' failed
The remainder of the build log tells that this is the first mention of
"powerpc64-linux-gnu/lib64". Instead the files mentioned are installed
in the intended location (where they would be copied to).
So I attempted a build with the same configuration except for disabling
wdotap (i.e. using the supported method) and indeed the supported method
does not fail here. This is why I am filing the bug against
cross-gcc-dev.
The relevant code can be found in gcc-4.9's debian/rules2[2] (search for
"slaps"). It is conditional to:
* DEB_CROSS = yes
* multilib = yes
* DEB_STAGE != stage1
* DEB_TARGET_ARCH = powerpc
* biarch64 = yes
Likely, this should also become conditional to
with_deps_on_target_arch_pkgs != yes. The interesting bit here is that
there is similar fix above this fix for DEB_TARGET_ARCH=s390. It is not
clear whether it should also be disabled for wdotap. In particular, this
cannot be tested, because glibc no longer builds for s390, so we cannot
satisfy Build-Depends.
What do you think? Opportunistically disable both or just the one we
know to be unneeded for wdotap? (Based on this description either patch
should be trivial.)
