python-distutils_2.6.6: config/Makefile contains sysroot

python-distutils_2.6.6: config/Makefile contains sysroot

[Kartik Mohta]

The Makefile (in /usr/lib/python2.6/config) used by distutils to
compile modules contains the original sysroot used while compiling
Python on the host:

CC=        arm-angstrom-linux-gnueabi-gcc -march=armv7-a
-mtune=cortex-a8 -mfpu=neon -mfloat-abi=hard -mthumb-interwork
-mno-thumb --sysroot=/home/kartikmohta/overo-oe/tmp/sysroots/armv7a-hardfp-angstrom-linux-gnueabi
CXX=       arm-angstrom-linux-gnueabi-g++ -march=armv7-a
-mtune=cortex-a8 -mfpu=neon -mfloat-abi=hard -mthumb-interwork
-mno-thumb --sysroot=/home/kartikmohta/overo-oe/tmp/sysroots/armv7a-hardfp-angstrom-linux-gnueabi

This leads to the following error when compiling modules using distutils:
/usr/lib/gcc/arm-angstrom-linux-gnueabi/4.5.3/../../../../arm-angstrom-linux-gnueabi/bin/ld:
this linker was not configured to use sysroots


Can these sysroot arguments be removed in the do_install_append() step
using a simple sed script?

you should try to figure out why binutils was build without sysroot. 
Check the configure args for binutils-cross

I guess there was some misunderstanding, the problem is that the
Makefile on the target contains references to the sysroot on the host.

Did you ever get this issue resolved? I'm having a similar problem now trying to
build matplotlib on an embedded processor running angstrom linux (python 2.6):

gnueabi/bin/ld:
