[Linuxsampler-devel] gigedit crashes when creating ne gig-file. pango/gtkmm3?

[Kolja K. <ko...@fr...>]

Hi all,

while testing some newly created gig-files I ran into some problems with gigedit. I think, this might have something to do with my installation of it.

When trying to install tha latest gegedit version (1.2.0), running
./configure
runs alright, but then make will give:

I'm on archlinux using
gtkmm3 version 3.24.5-2
and libgig from svn.

I managed to install gigedit by applying two patches:

gigedit-1.2.0-libdir.patch
gigedit-1.2.0-redeclare.patch

but have no clue, what exactly it is they're doing....

So far, so good.
But when trying to create a new gig -file with a sample and save it, gigedit will crash with:

** (gigedit:23922): ERROR **: 09:46:52.773: 
unhandled exception (type unknown) in signal handler

A gig-file is created though and I can load that into linuxsampler, but it wont play.
Opening it in gigedit again will show
Wav Data CRC-32: ffffffff
so my guess is, the crash appears when trying to save the sample data.

I again created a new gig-file and found that, when importing the sample and assigning it to a region, it will already show
Wav Data CRC-32: ffffffff
in gigedit before saving it.

This behavior is confirmed with different samples. 

Saving an already existing gig-file after changing it in gigedit however seems to work.


Are those issues related to each other?
- My guess is no.
Does anybody has an idea, what the root-cause might be?


Cheers,
Kolja
