Build failure

Gentlemen,

I have recently downloaded Audacity 1.2.6 in the form of a tarball. I
have tried to build the application; the build got a long way, but
eventually terminated with a compilation error. I am compiling on SuSE
Linux 10.2.

I would very much appreciate a helpful suggestion. Here are the messages
that are reported (running make a second time):

Hmm, I have a sense of deja-vu. I'm fairly sure I've seen this error
before, but I have no idea what it was caused by or how to fix it (not
surprisingly, it builds fine for me on Gentoo).

Looking back at mail archives it seems that the problem is building
audacity using wxuniv rather than wxGTK, which is the X11 implementation
rather than the GTK implementation. This wouldn't be a problem if wxuniv
was complete, however it's quite a long way from being complete, so
audacity doesn't work with it. There was at one time a patch to fix
this, but it never made into main code, because a lot of things had to
be disabled in order to make it compile.

So in essence, get wxGTK not wxX11 and you should be rolling.

Richard

Thank you for your advice.

I have successfully compiled audacity 1.3.3-beta. It seemed advisable to move to this version rather than do any retrograde installation of gtk+ and other packages.

I have been a user of audacity (an earlier version) on Windows for a while, and I am pleased with your improvements.

Sincerely,

Arnold Kochman
