Building on MacOS X
Get the latest development tools
Certain versions of Apple's Xcode tools are known to cause problems when building ghc 6.6. You should download the latest Xcode from the Apple Developer Connection website. Downloading requires that you sign up for a free membership in the Apple Developer Connection.
Once upon a time Apple distributed updates to Xcode by using their Software Update service but not anymore. You must download the development tools manually.
Successful builds have been reported using Xcode 2.4 and 2.4.1 on Intel and PowerPC Macs. Xcode 2.2.1 is known not to work out of the box on Intel Macs.
Getting Readline to work
Thanks to Paul R Brown for the following instructions.
Building GHC 6.6 out of the box on MacOS X will leave you with a GHCi binary that has no readline support. This is because MacOS X comes NetBSD's libedit and Apple has made /usr/lib/libreadline.dylib a symlink to libedit. libedit does not support all of the libreadline API that GHC requires, so the GHC configure script decides not to use it.
To get readline working, you first need to install GNU readline:
cd ~/work mkdir gnu-readline cd !$ curl -O ftp://ftp.cwru.edu/pub/bash/readline-5.2.tar.gz tar xzvf readline-5.2.tar.gz cd readline-5.2 ./configure make && sudo make install
Now you have to tell the GHC build about readline:
cd ~/work mkdir ghc cd !$ curl -O http://www.haskell.org/ghc/dist/6.6/ghc-6.6-src.tar.bz2 curl -O http://www.haskell.org/ghc/dist/6.6/ghc-6.6-src-extralibs.tar.bz2 tar xjvf ghc-6.6-src.tar.bz2 tar xjvf ghc-6.6-src-extralibs.tar.bz2 cd ghc-6.6 ./configure --with-readline-includes=/usr/local/include \ --with-readline-libraries=/usr/local/lib make -j && sudo make install
(-j tells make to spawn lots of processes building in parallel, it will probably save some time especially if you have a multi-core machine).
Building the distrbution
The following instructions are from Audrey Tang
Install the 6.4.1 bindist, download both source tarballs from http://haskell.org/ghc/download_ghc_66.html and extract both;
cd into ghc-6.6; sh configure; make; make install.
Then create mk/build.mk with one line:
then "make binary-dist", and tar the ghc-6.6/ directory produced.
Building using MacPorts
ghc 6.6 can be built from source using MacPorts on Intel and PowerPC Macs. Follow the instructions on the MacPorts website for installing the infrastructure and port files, then type
> sudo port install ghc
to build and install ghc. Dependencies will be built and installed automatically. There is no need to follow the instructions above for installing readline; this is handled by MacPorts dependency mechanism. If you want to see how the build is progressing, type
> sudo port -dv install ghc
The "-dv" flags indicate verbose debugging output. Using these can also help diagnose build problems.
If the build is interrupted or fails for some reason you must clean up before trying again. Do
> sudo port clean ghc
A nice feature of MacPorts is that you can put its installation directory tree anywhere. This allows installations without administrator privileges.
