Audacity Forum

Hello,

audacity does not run on 'linux from scratch'

audacity-src-1.3.13
glibc-2.7
alsa-1.0.19
linux-2.6.30

I try to start audacity on a shell in X11. For a very short time I see the audacity window.
But the program breaks with the following message.
In VLC or MPlayer 'Alsa' runs without problems. Where is the mistake?

Unfortunately that does not tell us much. I get those messages on Ubuntu 10.10, but then Audacity launches and works correctly.
I'd suggest that you have a go at building from the current svn head (1.3.14) and see if that sorts out the problem.

If the problem persists, then you may need to build a debug version to see where the problem lies.

there is a copy and paste bug in ./src/Menus.cpp" line 598
wrong code was:
c->AddItem(wxT("ResetToolbars"), _("&Reset Toolbars"), FN(OnResetToolBars), 0, AlwaysEnabledFlag, AlwaysEnabledFlag);
working is:
c->AddCheck(wxT("ResetToolbars"), _("&Reset Toolbars"), FN(OnResetToolBars), 0, AlwaysEnabledFlag, AlwaysEnabledFlag);

Unfortunately, c->AddItem is correct (it is NOT a "checkable" menu item). This is very strange that changing it to a checkable item fixes your issue. This is the same code from 1.3.10 (about a year ago):

when I go back to AddItem call, I get a segmentation fault on startup:
backtrace:
Core was generated by `audacity'.
Program terminated with signal 11, Segmentation fault.

If the function call is okay, then it has to do something with the parameters:
I changed
c->AddItem(wxT("ResetToolbars"), _("&Reset Toolbars"), FN(OnResetToolBars),0 , AlwaysEnabledFlag, AlwaysEnabledFlag);
to
c->AddItem(wxT("ResetToolbars"), _("&Reset Toolbars"), FN(OnResetToolBars), wxT("Ctrl+Shift+T"), AlwaysEnabledFlag, AlwaysEnabledFlag);
and now startup is okay.
I also had some problems with compiling (wx stuff - reverse functionality uses a class member which does not exist, MACRO definitions are missing on the ffmpeg stuff and on other sources). I made some Q&D chnages and now it seems to work fine for me ...

Cheers
