Currently I am doing git bisect to pinpoint the issue: Looking at current status of bisect, this commit is likely a culprit: commit 1cb4614f1d5e482b88ea372d1841a6c313a49941 Author: Eric BENARD <eric@eukrea.com> Date: Sun Feb 26 08:49:42 2012 +0100 gdb-cross-canadian: build gdb with python support * python support is needed for providing finer scripting control in gdb, and for remote controling gdb for example from qtcreator * gdb/configure tries to autodetect python using python executable with --includes --ldflags --exec-prefix to get the right flags As it's difficult to achieve in OE's context, we generate a script which will return the right values and make gdb's build system happy. This idea was taken from the following article : http://www.mentby.com/doug-evans-2/python-enabled-gdb-on-windows-and-relocation.html * tested using angstrom & armv7 target & qtcreator 201005 & 2.4.0 * MJ: updated paths to python as disscussed here http://lists.linuxtogo.org/pipermail/openembedded-core/2012-February/018222.html now it's easier with cross-canadian staging dir and SDKPATH fixed :) (From OE-Core rev: 73a90b88541c373aa5b83a939dd3b5f1fe05b9b8) Signed-off-by: Eric Bénard <eric@eukrea.com> Cc: fcooper@ti.com Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

khem pushed a fix for this: commit 45bc21c2752bdfe46a2ae262fec5acd0da185853 Author: Khem Raj <raj.khem@gmail.com> Date: Fri Mar 23 05:50:41 2012 -0700 gdb-cross-canadian: Fix linking issues when python support is enabled gdb-cross-canadian was linking with static version of libpython and looking for build host python when run. This could be mismatch between python-nativesdk and build host provided python. So we make it consistent to always use python-nativesdk Instead of adding bunch of -L we add -rpath and -rpath-link so that gdb finds all needed libraries in SDK and does not reach out into host This should fix yocto PR# 2077 as well.
