Hi, I've just emerge gpp 0.6. When I start it from the command line, it just hags there with no output (no segfault output, nothing). When I run it with strace, I see that it segfaults: ---CUT---- mkdir("/tmp/gconfd-charlie", 0700) = -1 EEXIST (File exists) open("/tmp/gconfd-charlie/lock/ior", O_RDONLY) = 13 fstat64(13,

I'm unable to reproduce this behavior, but it would be a good idea if you start by lowering the optimizations you set in your CFLAGS. Try removing most or all of them and run it again. Otherwise, try to provide a backtrace, after compiling gpp without optimizations and with appropriate debug flags. Thanks.
Compile with CFLAGS="-O2" and CFLAGS="-O" was the same.

How can I compile with "appropriate debug flags" as you say ? Thanks for your help.
you'll need to use CFLAGS like "-O1 -g" for debugging symbols. but it seems like something weird in /home/charlie/.gnome because it just stops there. is there a /home/charlie/.gnome/gpp ? maybe you might want to try to delete that? if that doesn't help, run : gdb gpp (gdb)$ r ... crashes .. (gdb)$ bt that should give you a backtrace which you should paste there.
I have searched everywere in the .gnome directory, couldn't find any trace of gpp or gnome-photo-printer. I have also tried to run it as another user, didn't help.

leonardop, the version is up to 0.6.3 by now.. maybe that fixes problems with it. If you add something pretty much beta quality i expect you to work on it and keep it up to date/fix bugs, otherwise it shouldn't have been added yet. reporter, try bumping the ebuild to 0.6.3 and see if it works. I'm not sure this package should be unmasked in portage at this time,
Yes, 0.6.3 works fine.
But then, I see that a gnome menu entry is still missing. It's not very convenient to have to start a command line every time... not very HIG... ;-)
Ok, version 0.6.3 is now in the Portage tree. Thanks for your input.
