Description David Michael 2020-11-28 19:20:32 UTC
The pkg_post* functions have bare calls to gnome2_giomodule_cache_update in glib-networking, which only works when compiling natively.  In glib, there is a cross-compiling conditional block that allows the build to succeed.  Compare:

Can that condition be copied to the calls in glib-networking?  Maybe just move it to the eclass so it's fixed everywhere?

Reproducible: Always

Steps to Reproduce:
1. cross-emerge -v net-libs/glib-networking

Actual Results:  
 * .ppc: running multilib_pkg_postinst
 * Updating GIO modules cache ...
/var/tmp/portage/net-libs/glib-networking-2.64.3/temp/environment: line 1630: /usr/powerpc-gentoo-linux-gnu/usr/bin/powerpc-gentoo-linux-gnu-gio-querymodules: cannot execute binary file: Exec format error                            [ !! ]
 * ERROR: net-libs/glib-networking-2.64.3::gentoo failed (postinst phase):
 *   Update GIO modules cache failed (for ppc)

Expected Results:  
It should build and install.

    gnome2-utils.eclass: skip executing cross-compiled tools
    Executing tools installed in ROOT will fail when cross-compiling,
    so this prints a warning about manually running the command instead
    in that case.  The warning is copied from dev-libs/glib.
    This also reorders the exception handling by increasing severity so
    that the "nothing to do" non-error returns first, otherwise the
    expected problem of unexecutable cross-compiled commands returns,
    otherwise the unexpected problem of missing commands returns.
    The immodule cache functions were updated to handle a different
    problem.  They run native tools from BROOT, but they are not
    guaranteed to exist while cross-compiling (e.g. gtk+ can't BDEPEND
    on itself, so the cross-compiled gtk+ can be installed before the
    native gtk+, which fails from gtk-query-immodules not existing).
