[Bf-committers] Bf-committers Digest, scons issues with new ffmpeg package

[João Eduardo]

Yes blenderplayer is broken for me too under Linux 32 bits.

Compiling ==> 'buildinfo.c'
Linking program ==> 'blender'
Linking program ==> 'blenderplayer'
/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../lib/crt1.o: In function
`_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status
scons: ***
[/home/katana/monografia/blender/novo_blender/build/linux2/bin/blenderplayer]
Error 1
scons: building terminated because of errors.

Cya...
