Quick Start to just building GHC

Below are quick instructions for just building and installing GHC. If you are an aspiring GHC developer, read the Newcomers page instead.

The following instructions assume that you have got the sources and installed the necessary tools. In particular for Windows users, all the commands below must be executed in the MinGW shell, not Command Prompt or PowerShell.

Optionally, you customize your build by creating the file mk/build.mk using mk/build.mk.sample as a template.

If you obtained the repository via git clone --recursive, you will need to first run:

$ ./boot

This step isn't necessary if you obtained the source from a tar archive.

Next, run the ./configure script followed by make to start the build:

$ ./configure # Windows users must append "--enable-tarballs-autodownload"
$ make

On Windows you need to download some binary distributables before being able to build. This only has to be done once and can be done by adding the --enable-tarballs-autodownload flag to the call to ./configure.

By default (without any mk/build.mk customization), this will do a 2-stage bootstrap build of the compiler, with profiling libraries.

Run without installing

You can find the binaries built by make in the inplace/bin directory under the root of the ghc source tree. The binaries can be run from here without installing.

Installing

After building, to install GHC (by default in /usr/local):

$ make install

You may need to use sudo.
