Source: gcc-4.2
Version: 4.2.2-7
Severity: normal
Tags: patch
I am trying to build a cross compiler targeting amd64, using the method
described at <http://www.emdebian.org/tools/crossdev.html>:
* Build and install cross-binutils
* Convert and install libc etc. with dpkg-cross
[ NB: libc6-i386, libc6-dev-i386 and lib32gcc1 may need manual
conversion - see Bug #463588 ]
* gcc:
$ export GCC_TARGET=amd64
$ cd gcc-4.2-4.2.2
$ debian/rules control
$ dpkg-buildpackage -b -rfakeroot
Below is the tail of the output from the last step. This turns out to be
just the first of several errors in debian/rules.d/binary-libstdcxx-cross.mk:
* The commands for make target $(binary-stamp)-lib32stdcxx use variables
$(dirs_lib32) and $(files_lib32), which are not defined anywhere.
Fixed by adding definitions analogous to those for _lib and _lib64.
* In the same rule, the commands to move libraries to the debug package
directory say usr/$(DEB_TARGET_GNU_TYPE)/lib/debug where they should
be using .../lib32/... .
* In the same rule, dh_makeshlibs is not invoked, causing subsequent
shlibs manipulation to fail.
* In the lib, lib64 and lib32 rules, dh_shlibdeps either fails or finds
the wrong libraries, because it searches the build host's libraries
and not the cross lib dir. "Fixed" with -l option, but may still
misbehave if the required cross libs are not installed - arguably a
deficiency of dpkg-shlibdeps.
* The lib32 and lib64 rules run dh_gencontrol for the corresponding
debug package, but not dh_installdeb. This makes dpkg-genchanges fail
when it cannot find a deb listed in debian/files.
* lib32stdc++ is built but is left out of the generated control file.
I attach a patch for all of the above.
