New submission from David <[email protected]>:
Hi all,
I fail on cross compiling Python 2.7.14 for ARM using a self built toolchain.
Build host: Linux x86-64 CentOS 7
Target: arm cortex-a9
My steps are compiling python for the host, after that compiling python for the
target using the PYTHON_FOR_BUILD flag with the prior built python.
Compile settings:
cd /home/op/Projekte/Cross_Linux/src/Python-2.7.15 && ./configure
--host=arm-cortexa9_neon-linux-gnueabihf ac_cv_file__dev_ptmx=no
ac_cv_file__dev_ptc=no ac_cv_have_long_long_format=yes --enable-shared
--disable-ipv6 --build=x86_64-pc-linux-gnu
PYTHON_FOR_BUILD=/home/op/Projekte/Cross_Linux/hostsrc/../root/bin/python
--prefix=/home/op/Projekte/Cross_Linux/src/Python-2.7.15/_install || exit 11 ;\
make -C /home/op/Projekte/Cross_Linux/src/Python-2.7.15 V=1 || exit 12
;\
make -C /home/op/Projekte/Cross_Linux/src/Python-2.7.15 install V=1 ||
exit 13 ;\
Last snippet from the build log for the target:

I can't get rid of the wrong compiler flags -m64 and -mtune=generic.
Target python build log attached.
