To build this package using Cabal directly from Git, you must run
autoreconf before the usual Cabal build steps (configure/build/install).
autoreconf is included in the GNU autoconf tools. There is no need to run
configure script: the
cabal configure step will do this for you.
If you are building from a source tarball, you can just use the standard Cabal installation stanza:
cabal configure cabal build cabal install
Xinerama support is enabled by default if Xinerama headers are detected. To
disable Xinerama support, add the
--without-xinerama flag to
cabal configure --configure-option="--without-xinerama"
However, if you are building from Git, X11 uses
autoconf, so you need
autoconf installed and run
autoheader before building:
