GumROS log4cxx compilation problem

I want to install GumROS to my Overo Fire. I have followed the tutorial on the ROS wiki[1]. Before compiling ROS, I need to compile and install patched version of log4cxx. I got source then configure it with:

./configure --prefix=/opt/gumros \
            --host=arm-linux \
            --with-apr=/opt/gumros \
            --with-apr-util=/opt/gumros \
            ac_cv_file__dev_zero=yes \
            ac_cv_func_setpgrp_void=yes \
            apr_cv_tcp_nodelay_with_cork=no \
            apr_cv_process_shared_works=no \
            apr_cv_mutex_robust_shared=no \
            ac_cv_sizeof_struct_iovec=8

and then i have managed to make install. Everything was fine up to this point. But while i was trying "sudo make install", i got following error:

libtool: install: warning: relinking `liblog4cxx.la'
/usr/bin/ld: ~/overo-oe/tmp/sysroots/armv7a-angstrom-linux-gnueabi/usr/lib/crti.o: Relocations in generic ELF (EM: 40)

make: *** [install-recursive] Error 1

I especially do not understand the error:

~/overo-oe/tmp/sysroots/armv7a-angstrom-linux-gnueabi/usr/lib/crti.o: could not read symbols: File in wrong format

PS: GCC v4.3.3 (which: ~/overo-oe/tmp/sysroots/i686-linux/usr/armv7a/bin/gcc)

Thanks in advance

Libtool is relinking when doing the install step. Ive not had any other toolchain I've tried with log4cxx, but the angstrom one built from open-embedded does. Oddly enough, it only does it for log4cxx as well, not apr_util, so it maybe a problem with its linking on c++ targets (apr_util is c).

The symptom: when relinking in the install step it links differently than it did in the build step - the notable problem is that it adds -L/usr/lib to the library search path (you should be able to see this a little above the error message), which means it brings the wrong format libraries to the table.

This seems to be a recent common problem with openembedded and their toolchains, see here for details. Lots of other links if you google about it too.

I'm currently looking to see if there's a workaround I can put in eros_log4cxx and also testing to see if the more recent versions of openembedded versions have fixed this problem (I read they addressed it in head).

Quick update : just built a toolchain targeted for the beagleboard via open embedded, and it has no problem when relinking. Who builds your toolchain?
