Cross compiling for OpenWRT mips

[magnusja]

Hey guys,

I am trying to get this library to work on a carambola2 (MIPS; OpenWRT) as described here: https://forum.openwrt.org/viewtopic.php?id=47600

I downloaded the most recent carambola2 toolchain from here: http://pkg.8devices.com/carambola2/v2.8/

Unfortunately I am only getting errors:

Any hints?

Unfortunately I don't know anything about cross-compiling python modules. If someone who knows how this should be done wants to write up a section in our docs we could review/merge it though.

Hey guys,

@amiralis Unfortunately not, because I am not creating opkg packages out of the python module.

Nevertheless I succeeded in cross compiling, the problem was that distutils passed the wrong optimazation flags to the compiler. I had to modify /usr/lib/python-2.x/distutils/sysconfig.py as described here: http://stackoverflow.com/questions/19779416/remove-all-default-compilar-arguments-in-setup-py

Very strange issue/bug of disutils, but it worked in the end!

@mjdev Great! Glad you got it sorted.
