Building & Installing ===================== +For full information on building GHC, see the GHC Building Guide [3]. +Here follows a summary - if you get into trouble, the Building Guide +has all the answers. + NB. you need GHC installed in order to build GHC, because the compiler is itself written in Haskell. It is possible to build GHC using just a C compiler, but we don't recommend this as the normal route. If you -*really* want to do it this way, then see the Building Guide (link -below). +*really* want to do it this way, then see the Building Guide. + +If you're building from darcs sources (as opposed to a source +distribution) then you also need to install Happy [4] and Alex [5]. -You also need a few other tools installed: Happy [4], Alex [5], and -Haddock [6] (for building library documentation), and a good DocBook -XML toolchain if you want to build the compiler documentation. +For building library documentation, you'll need Haddock [6]. To build +the compiler documentation, you need a good DocBook XML toolchain. Quick start: the following gives you a default build: - $ autoreconf - $ ./configure - $ make - $ make install + $ sh boot + $ ./configure + $ make + $ make install -The autoreconf step is only necessary if this is a tree checked out +The "sh boot" step is only necessary if this is a tree checked out from darcs.

It can take a long time.
