Created attachment 255053 [details, diff] dbus-glib-0.86.ebuild.patch Fix the build error by instructing the build system to use the native dbus-binding-tool
Wouldn't it be even better to set this parameter always so that it also benefits prefix setups ?
I don't think prefix is affected by this, they compile for the same architecture as the host so running the just compiled dbus-binding-tool will not fail. And setting it all the time is dangerous as it might break regular builds, if the system did not previously have dbus-glib installed or are upgrading from a version that is too old.
this tool is owned by dbus, not dbus-glib :) My comment was not about the arch problem but the location of the tool on a prefix system. CCing prefix anyway so they can give us the word :)
(In reply to comment #6) > this tool is owned by dbus, not dbus-glib :) but dbus-glib seems to have it included (and built) as well :/ > My comment was not about the arch problem but the location of the tool on a > prefix system. CCing prefix anyway so they can give us the word :) It works fine because: [DBUS_BINDING_TOOL=$withval],[DBUS_BINDING_TOOL=\$\(top_builddir\)/dbus/dbus- binding-tool]) In other words, if you don't set that argument, it will always use the included version of the tool, which in Prefix is also correct. It probably saves you some compilation (/me likes) if you don't use the included one, by indeed unconditionally doing something like: --with-dbus-binding-tool="${EPREFIX}"/usr/bin/dbus-binding-tool on an EAPI=3 ebuild.
(In reply to comment #7) > (In reply to comment #6) > > this tool is owned by dbus, not dbus-glib :) > > but dbus-glib seems to have it included (and built) as well :/ erm, forget that, it's not in dbus package after all, my qfile foo failed me :) so I guess the attached patch will do.

I don't think it's okay to depend on a host binary for this. Is building the examples really required?

Prefix outta here
still a thing, as new firefox-69.0 always needs dbus-glib as a compile time dependency. it's possible to cross-compile the package and thus the library, by adding --with-dbus-binding-tool=/usr/bin/dbus-binding-tool to local myconf=() dbus-binding-tool is part of dbus-glib, so for this the host has to have dbus-glib installed before it can be cross compiled. I really hope this mess of depending on a long depreceated library get's cleaned up in the near future at mozilla.
Created attachment 674389 [details] Fix cross-compiling Here is a proper fix for this ebuild so you don't have to worry about whether a CBUILD dbus-glib was installed or not.

I have no problems building for armv7a from amd64. It seems odd that your CBUILD compiler says libraries in /usr/lib are incompatible. Maybe you have a bad pkgconfig file adding -L/usr/lib when it should default to /usr/lib64? My native linking command looks like this when cross-compiling: libtool: link: x86_64-pc-linux-gnu-gcc -O1 -pipe -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align -Wfloat-equal -Wsign-compare -fno-strict-aliasing -o .libs/test-profile test-profile.o ../../dbus/.libs/libdbus-glib-1.so ../../dbus-gmain/tests/.libs/libtest.a -ldbus-1 -lgio-2.0 -lgobject-2.0 -lglib-2.0 Maybe try adding tc-env_build before the emake call to reset the environment.
Oh, nevermind, I see your linking command didn't fail. The program segfaulted. I don't know what to tell you about that. Try to reproduce it in gdb and see what broke.
