fails to build with "undefined references"

[rostedt@…]

I just did a svn update (been a while since my last one).

$ svn update
$ make distclean
$ ./configure --enable-gui
$ make

it failed the final link with:

I don't see any of the libavcodec/x86 files being built, which is where those undefined variables are created.

This is unreproducible and missing necessary information. What does config.mak contain, for starters?

[rostedt@…]

config.mak

[rostedt@…]

Sorry about that. Here's the file.

Also doing a svn log gives me this as the first line:

r31411 | diego | 2010-06-14 07:46:40 -0400 (Mon, 14 Jun 2010) | 2 lines

Remove unnecessary and unused #defines.

[diego@…]

Please try a fresh checkout and reopen the bug if the problem persists. Other than that I don't see a way how these files could fail to get built...

[rostedt@…]

Thanks, it must have been something messed up with the svn update. After deleting the directory and doing a fresh checkout, it worked. Sorry for wasting your time.
