Installation of Speex

This package consists of two separate tarballs. They need to be extracted and built independently.

Install Speex by running the following commands:

./configure --prefix=/usr    \
            --disable-static \
            --docdir=/usr/share/doc/speex-1.2rc2 &&
make

This package does not come with a test suite.

As the root user:

make install

Now extract and install the speexdsp package:

cd ..                          &&
tar -xf speexdsp-1.2rc2.tar.gz &&
cd speexdsp-1.2rc2             &&

patch -Np1 -i ../speexdsp-1.2rc2-build_fixes-1.patch &&

./configure --prefix=/usr    \
            --disable-static \
            --docdir=/usr/share/doc/speex-1.2rc2 &&
make

Again, as the root user:

make install

Command Explanations
