libstc++ libtool problem, cross lamanger broken

Hi,

I've been getting failures when ARM apps try to link with x86_64
libxml2, and I started to do some digging:

grep L/OE/angstrom-dev/sysroots/x86_64-linux/usr/lib
/OE/angstrom-dev/staging/armv7a-angstrom-linux-gnueabi/usr/lib/*.la |
more | awk -F: '{print $1}' | sed
s:/OE/angstrom-dev/staging/armv7a-angstrom-linux-gnueabi/usr/lib/::glibaspell.la
libatkmm-1.6.la
libcairomm-1.0.la
libetpan.la
libFLAC++.la
libgdkmm-2.4.la
libgiomm-2.4.la
libglibmm-2.4.la
libglibmm_generate_extra_defs-2.4.la
libgnutlsxx.la
libgtkmathview_custom_reader.la
libgtkmathview_libxml2.la
libgtkmathview_libxml2_reader.la
libgtkmm-2.4.la
libmathview_backend_gtk.la
libmathview_backend_ps.la
libmathview_backend_svg.la
libmathview_frontend_custom_reader.la
libmathview_frontend_libxml2.la
libmathview_frontend_libxml2_reader.la
libmathview.la
libpangomm-1.4.la
libpcrecpp.la
libpoppler-glib.la
libpoppler.la
libpspell.la
libschroedinger-1.0.la
libsidplay.la
libsigc-2.0.la
libstdc++.la
libsupc++.la
libtiffxx.la
libwebkit-1.0.la

So pretty much anything with a c++ dep gets a bogus .la file, so lets
look at libstdc++.la:

dependency_libs=' -L/OE/angstrom-dev/sysroots/x86_64-linux/usr/lib
/OE/angstrom-dev/sysroots/armv7a-angstrom-linux-gnueabi/usr/lib/libstdc++.la'

So it looks like the cross.bbclass lamangler needs some more work.

regards,

Koen

Koen

my sysroots/armv5te-oe-linux-gnueabi/usr/lib/libstdc++.la file has
dependency_libs=' -lm'
I am not able to reproduce the problem on my end
What am I missing ?

Thx

this -L only gets in with gcc 4.3 and not with gcc 4.4

Using gcc 4.4.x isn't an option for angstrom, it generates way too slow
code for arm. Those regressions are fixed in gcc 4.5.x, though, which
incidentally is what the angstrom-next branch is using.

nice to know. So probably you have to wait a little for 4.5 to mature.
anyway I have committed a fix for 4.3 problem, try it out. I have done limited
testing myself. Let me know if it breaks anything else.
