Compiling aoTuV

The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.

This information is older and requires a rewrite. It may or may not work on some of the newer AoTuV forks.

Here are notes for compiling aoTuV under Linux in case you do not want to use the pre-compiled binaries. If for example you want to optimize for your CPU, want to link other programs, or if you don't use an Intel-compatible CPU henceforth (AMD64 architectures).

Get the patched libvorbis source code from the aoTuV website
unpack the tarball and change into a temporary directory then you can use to build the software.
If you want to overwrite your existing vorbis libraries:

CFLAGS=-fno-strict-aliasing sh ./configure

make

make install

If you want to keep your existing libraries:

CFLAGS=-fno-strict-aliasing sh ./configure --prefix=/usr/local

make

make install

Call oggenc as

LD_PRELOAD=`echo /usr/local/lib/libvorbis*.so` oggenc -q4 foo.wav

The flag -fno-strict-aliasing is necessary if you compile with gcc 4, see the thread on HydrogenAudio.
