Package: dpkg-dev
Version: 1.18.4
Severity: normal
Hello,
In Objdump.pm, we use debarch_to_gnutriplet(get_host_arch()).'-objdump';
to run dpkg-shlibdeps on package objects.
When building a cross-compiler, this is however not working. The
cross-compiler itself is fine (since it's host), but the cross-compiler
package also ships a few *target* objects, and for them one would have
to use something like
debarch_to_gnutriplet(get_target_arch()).'-objdump';
That however doesn't seem to exist in libdpkg-perl yet. Also, dpkg-shlibdeps
will probably need to try both, because it can't know which objects are
for the host or for the target.
Otherwise, we for instance get this while building a cross gcc:
dpkg-shlibdeps -Tdebian/gcc-5-x86-64-linux-gnu.substvars
debian/gcc-5-x86-64-linux-gnu/usr/bin/x86_64-linux-gnu-gcc-5

/usr/bin/objdump: debian/libgcc1/lib/x86_64-linux-gnu/libgcc_s.so.1: File
format not recognized
That happens when the build and host are a 32bit architecture which
doesn't have multilib support and target is a 64bit architecture, and
thus its native objdump probably does not understand 64bit binaries.

hated the Mighty Mouse at work whenever I set up a Mac for somebody.
<D> I decided to give it one last chance when I set up my new Mac
<D> And golly, I like it at home.
<D> Maybe mine is defective in a way that makes it good.
