Great Frederic!, 

you can find instructions below, but first, some important comments
about some integration issues:

-These tests take a *lot lot lot* of execution time -> this might be a
problem. Maybe we should consider filtering some of them, or something
to make them a bit less painful. I'll post something about this later
on.

- Some tests seem to hang (I needed to send a Crtl+C to stop them
manually) -> this *is* a problem, at least using TET (Check provides
timeout support).

- You need an X server up and running (GTK+ requisiton).

- If we want to use Check as testing framework instead of TET (as Fer
suggests) it will take some more time. I know Fer has already done some
work on this but I do not know exactly its current state. Anyway, I'll
send what should be done to achive this in a later post.


INSTRUCTIONS
----------------------------------

These are the instructions for gtkvts using TET as testing framework,
which is the project I have tried:

1. Download TET3-lite (the testing framework) from here:
http://tetworks.opengroup.org/tet/

2. Checkout GTKVTS from gnome cvs (do it inside TET3 root directory):
cvs -d :pserver:anonymous anoncvs gnome org:/cvs/gnome co gtkvts

3. Follow instructions in gtkvts/README file.

Some tips:

- I needed to configure gtkvts with --with-no-hdr-tests=TRUE, otherwise
it complains about an empty directory.

- I needed to fix a memory allocation problem inside the tests generator
(/src/tools/testgen/):

# cvs diff func_tests_gen.c
Index: func_tests_gen.c
===================================================================

Cheers,
