Installation of EsounD

Install EsounD by running the following commands: 

LIBS=-lm ./configure --prefix=/usr --sysconfdir=/etc &&
make

This package does not come with a test suite.

Now, as the root user: 

make install docdir=/usr/share/doc/esound-0.2.41

If you have DocBook-utils installed, still as the root user: 

chown -v root:root /usr/share/doc/esound-0.2.41/*

Command Explanations

LIBS=-lm: Make sure the linker uses the math library.

--sysconfdir=/etc: This switch puts configuration files in /etc instead of /usr/etc.

--disable-static: Prevent the static libraries being built.
