[Xen-devel] configure: error: Unable to find Python development headers

[Steve Freitas <sflist@xxxxxxxxx>]

Hi,

I'm trying to do some bisection to find the cause of my VGA passthrough 
issues, but gcc 4.9 is throwing too many warnings, all of which are 
interpreted as errors, which kills the build. So I'm trying to compile 
with 4.8. Unfortunately, ./configure chokes because it says it can't 
find Python.h. However, I do have it installed on my system. (Indeed, I 
have no problem building RELEASE-4.4.1 and 4.5rc-1 with gcc 4.9, it's 
just problematic at various points between those two versions.)

steve@g2:~/git/xen$ ll /usr/include/python2.7/Python.h
-rw-r--r-- 1 root root 4329 Oct  7 11:48 /usr/include/python2.7/Python.h

I'm on Debian Jessie. Any idea what I might be doing wrong?

Thanks!
