Compilation instructions:
First you must download wxWidgets 2.6.x from:
http://www.wxWidgets.org/
If you install the RPM, make sure you install the devel RPM
as well, otherwise, you won't be able to compile Audacity
from source.
To compile on Linux, Mac OS X, and other Unix systems,
simply execute these commands:
./configure
make
make install # as root
To see compile-time options you can set, you can type
"./configure --help".
If you want to do any development, you might want to generate
a configure cache and header dependencies:
./configure -C
make dep
To compile on Windows using MSVC++, please follow the
instructions found in compil
