Compiling on Fedora 19, 64bit & gnucash python bindings 64 bit

[Alex Aycinena]

Geert,

I noted that you are using Fedora 19, 64bit from your message to John:

I recently upgraded my laptop to Fedora 19, 64bit, and my desktop is still
Fedora 18, 64bit. The latest release, r23146, builds fine on F18, but when
I try to build this same release on F19, I get a bunch of swig errors as
follows:

My F18 has swig 2.0.8-1 while F19 has 2.0.10-1. Perhaps that is the cause.

What did you do to get gnucash to build on F19?

I also wanted to ask on the list about compiling gnucash for the python
bindings in a 64bit environment. When I configure with --enable-python, I
get:

configure: error: cannot find Python.h in /usr/include/python2.7

In have python 2.7 installed (in fact a lot of python related packages). I
don't know if the problem is a missing package or a 32-bit vs. 64-bit issue.

Have you compiled with --enable-python and gotten it to work on F18 or 19
64bit? Can you, or anyone else give me some pointers as to what to do?

Thanks and regards,

Alex
