Isn't the emulator native? why do you need to bind Python to the ARM binaries?

Thanks Jose,
On native platform, its working for me as well. I think I have to re-compile or
cross-compile 32-bit python using ARM tools e.g. using something like
CXX=arm-none-linux-gnueabi-g++ and then rebuild robot framework.
I have to compile the emulator files using arm-tool chain and I am including
the 32-bit python in it built with native gcc toolchain.
If anyone else has some suggestions that I will really appreciate!

Asunto: Fwd: Embedding python in emulator
Hi,
Has anybody embedded python in C/C++ application. My platform is 64-bit and
python binaries I am using for Runtime/emulator is 32-bit. I have added
following flags in CFLAGS and LDFLAGS to compile and link the c/c++ files in
emulator with (#include </path/32-bit-python/include/python.h>)
CFLAGS += -I/opt/pym32/bin/include/python2.7 -fno-strict-aliasing -DNDEBUG -g
-fwrapv -O3 -Wall -Wstrict-prototypes
LDFLAGS += -L/opt/pym32/lib/python2.7/config -lpthread -ldl -lutil -lm
-lpython2.7 -Xlinker -export-dynamic
The files compiles but breaks when linking. Can anybody help with following
errors:

To: Pekka Nikander <pekka.nikander@xxxxxx<mailto:pekka.nikander@xxxxxx>>
Hi Pekka,
I am trying to include python.h in emulator/inc/register.h
I have to include cflags and ldflags in Makefile system of emulator e.g.
-I/opt/include/python2.7 -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall
-Wstrict-prototypes
-L/opt/lib/python2.7/config -lpthread -ldl -lutil -lm -lpython2.7 -Xlinker
-export-dynamic
However, I am getting:

-----------------------------------
Can you help me in including these flags in the Makefile system and link the
python with it? It will help a lot, to call from c to python independently.
