On Linux, Vavoom 1.25 and later fails to compile if FLAC support is enabled (--with-flac) and [u:46mj1zv5]flac-1.2.1[/u:46mj1zv5] is installed. The error is:

[EDIT] It occurs only on Linux X86_64, on x86 systems it builds fine.

Confirmed on my box.

Hopefully fixed. Check it out.

The error is partially solved. The second part of the error output remains:

s_flac.cpp: In static member function ‘static VAudioCodec* VFlacAudioCodec::Create(VStream*)’:
s_flac.cpp:604: error: cannot allocate an object of abstract type ‘VFlacAudioCodec::FStream’

[EDIT] Wow, i figure out how fix this issue <!-- s8) --><img src="{SMILIES_PATH}/icon_cool.gif" alt="8)" title="Cool" /><!-- s8) --> Here's the missing patch:

I tried compiling this on winblows myself, but the game freezes when playing the flac samples <!-- s:( --><img src="{SMILIES_PATH}/icon_sad.gif" alt=":(" title="Sad" /><!-- s:( -->. Maybe there's some other change in the new version of libflac.

Should compile fine now.

[quote="Janis Legzdinsh":2ixt3rtf]Should compile fine now. Yeah, it's finally fixed. i can confirm it. <!-- s8) --><img src="{SMILIES_PATH}/icon_cool.gif" alt="8)" title="Cool" /><!-- s8) -->
