The Bison package contains a parser generator. Estimated build time: &bison-time; Estimated required disk space: &bison-compsize; &aa-bison-down; &aa-bison-dep;   First fix a minor compilation problem that Bison has with some packages, the patch is backported from CVS: patch -Np1 -i ../&bison-patch; Now prepare Bison for compilation: ./configure --prefix=/usr Compile the package: make This package has a test suite available which can perform a number of checks to ensure it built correctly. Should you choose to run it, the following command will do so (and takes a long time): make check And install the package: make install &aa-bison-shortdesc; &aa-bison-desc;
