Subject: build: check for python-config in configure
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9ed02fc793b332773658f3ba09f45a058e75b0a8;p=qemu-gpiodev%2Flibgpiod.git

build: check for python-config in configure

Currently, configure succeeds when python is installed without its
development components, i.e. python-config and headers. The subsequent
make will fail when gcc cannot locate Python.h.

This patch fixes that behavior by throwing an error at configure-time if
python-config cannot be found.
