media-libs/gstreamer-0.10.20: 'xmerge gstreamer' fails with link-time error /usr/lib/libgobject-2.0.so: could not read symbols: File in wrong format xmerge is emerge wrapper, as described in Gentoo Embedded handbook. Reproducible: Always Steps to Reproduce: 1. Setup cross-compile enviroment for arm as described in Gentoo Embedded handbook 2. xmerge gstreamer Actual Results: emerge fails to build gstreamer. Error is "/usr/lib/libgobject-2.0.so: could not read symbols: File in wrong format". Expected Results: successful build of gstreamer Here is the last command arm-module-linux-gnueabi-gcc -shared .libs/libgstreamer_0.10_la-gst.o .libs/libgstreamer_0.10_la-gstobject.o <... tons of .lib/*.o libraries ... > .libs/libgstreamer_0.10_la-gstmarshal.o -Wl,--whole-archive parse/.libs/libgstparse.a -Wl,--no-whole-archive -lpthread /usr/lib/libgobject-2.0.so /usr/lib/libgthread-2.0.so /usr/lib/libgmodule-2.0.so /usr/lib/libglib-2.0.so /usr/lib/libxml 2.so -lrt -ldl -Wl,-O1 -pthread -Wl,-soname -Wl,libgstreamer-0.10.so.0 -Wl,-version-script -Wl,.libs/libgstreamer-0.10. ver -o .libs/libgstreamer-0.10.so.0.17.0 /usr/lib/libgobject-2.0.so: could not read symbols: File in wrong format I think, that linker tries to use some HOST system's libraries like libgobject.so

I have no idea what xmerge tries to do...
This package compiles when using crossdev-wrappers vs xmerge. crossdev-wrappers provides lots of per chost config.site values.
Here is my xmerge #!/bin/sh if [ ! -d "$SYSROOT" ] ; then echo "SYSROOT is not set" >&2 exit -1 fi export CBUILD=$(portageq envvar CHOST) export PORTAGE_CONFIGROOT=${SYSROOT} export ROOT=${SYSROOT} exec emerge "$@"
Ok, i found that it is not gstreamer-related bug, but libtool-related. Here is the source http://bugs.gentoo.org/262298. Here are the similar bugs in other libs http://bugs.gentoo.org/show_bug.cgi?id=158040 http://bugs.gentoo.org/show_bug.cgi?id=261423 There are some (more or less ugly) workarounds - Temporary rename /usr/lib/libgobject.so to smth else and repeat xmerege gstreamer - Add global LDFLAGS += -L/usr/arm-unknown-linux-gnueabi/usr/lib - Patch the libtool *** This bug has been marked as a duplicate of bug 262298 ***
Note: media-libs/gstreamer-0.10.31 still suffer from libtool bug. But modern crossdev-wrappers has cross-fix-root script. I launch it and re-emerge gstreamer. It builds successfully.
