Source: gcc-4.6
Version: 4.6.1-15
Severity: wishlist
Tags: patch
User: crossbuild@debian.org
Usertags: cross

When building in REVERSE_CROSS mode (IE: when trying to build a native
compiler for another architecture with an existing cross-compiler, the
build fails with the following error:

  $ apt-get source gcc-4.6=4.6.1-15
  $ ( cd gcc-4.6-4.6.1 && dpkg-buildpackage -apowerpcspe -b -us -uc )
  [...]
  dh_strip -pgcc-4.6-plugin-dev
  powerpc-linux-gnuspe-strip: Unable to recognise the format of the input file `debian/gcc-4.6-plugin-dev/usr/lib/gcc/powerpc-linux-gnuspe/4.6/gengtype'
  dh_strip: powerpc-linux-gnuspe-strip --remove-section=.comment --remove-section=.note debian/gcc-4.6-plugin-dev/usr/lib/gcc/powerpc-linux-gnuspe/4.6/gengtype returned exit code 1
  make[1]: *** [stamps/08-binary-stamp-gcc-plugindev] Error 29
  make[1]: Leaving directory `/srv/stuff/toolchain/CROSS/gcc-4.6/gcc-4.6-4.6.1'
  make: *** [binary] Error 2
  dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2

A brief inspection of the gengtype program shows that it is in fact a
binary built for the build system:
  $ file debian/gcc-4.6-plugin-dev/usr/lib/gcc/powerpc-linux-gnuspe/4.6/gengtype
  debian/gcc-4.6-plugin-dev/usr/lib/gcc/powerpc-linux-gnuspe/4.6/gengtype: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xfcaf9384cfcf05212c599e6334d7de5bd062c5de, not stripped

As far as I can tell, the "gcc-plugin" support is not supported when
building in REVERSE_CROSS mode and should be disabled.

Please review and apply the attached patch.

Unfortunately, the build still does not complete due to a different
error, one which I will be submitting as an additional followup bug.

Cheers,
Kyle Moffett
