[SOLVED] python-gpios-module-for-a20-olinuxino-mic

[Mouchon]

Hi
i try to install it from package
with following command:

python setup.py install

first time the CHANGES.TXT was missing.

doing a touch CHANGES.TXT resolve the problem. But after i have this

python setup.py install
running install
running build
running build_py
running build_ext
building 'A20_GPIO' extension
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c source/gpio_lib.c -o build/temp.linux-armv7l-2.7/source/gpio_lib.o
source/gpio_lib.c:39:22: fatal error: gpio_lib.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1


So seem that gpio_lib.h is missing from the package too.

Get last version of the packages and compile and work fine.

Looks like the pre-requisite is to
apt-get install python-dev

before attempting to build this library

[martinayotte]

The error comes because you missing the package python-dev.

Simply execute the command "apt-get install python-dev", then redo "python setup.py install"

Thanks, I just tried that, it works! (post updated)
