Work has begun on replacing the build system described below with a cross platform script using scons. If you want to try this new system please read [[Yhc/Scons]]. The system described below will continue to work for some time while the Scons based system is being finalised.

If you want to build the yhc compiler itself (not strictly necessary), you will need a very recent Haskell compiler, e.g. ghc >= 6.4. The supplied configure script will not detect if your compiler version is too old, and will not accept alternative names like ghc-6.4 instead of ghc.

== Building on Windows ==
 
 
Open a console at the root of the yhc tree. There is a file called Makefile.bat, which is used to build the various components. Just typing Makefile should give you a list of the options.
 
 
The modes are:
 
 
* yhc - build the compiler, requires GHC
 
* yhi - build the runtime, requires Visual Studio 2003 (ask for support for other compilers)
 
* yhe - build the evaluator, requires GHC
 
* gyhe - build the graphic evaluator, requires GHC and Gtk2Hs (Gtk2Hs HEAD only)
 
* doc - build the documentation, requires haddock and GHC
 
* lib - build the base libraries
 
* test - run the standard tests
 
   
The standard options are:
+
{- maybe darcs get --partial http://www.cs.york.ac.uk/fp/darcs/yhc/ is more recent? -}
   
* debug - build in debug mode [default]
+
There is a buildbot script that runs on every change, the results of which are available [http://www.indiegigs.co.uk:8010/ here]. If the build is busted, hopefully the developers will fix it soon. If your build is busted, but the buildbot succeeds, [[Yhc/Buildbot| consider adding your machine as a buildbot slave]] - then it will never get broken again.
* release - build in release mode
 
   
All compiled binaries will go into \inst\bin. To compile and run the test suite do:
+
== Building ==
   
$ Makefile yhc
+
To build yhc simply type 'scons' into a console Window. This should automatically detect your build environment and place the Yhc binaries into inst/
$ Makefile yhi
 
$ Makefile yht
 
$ Makefile lib
 
$ set YHC_BASE_PATH=<current directory>\inst
 
$ Makefile test
 
   
You may wish to set your YHC_BASE_PATH globally, in which case go to My Computer, Properties, Advanced, Environment Variables, New.
+
To build parts of Yhc separately the following commands can be used:
  +
* scons configure - Just configure.
  +
* scons build - Don't update dependencies, just build.
  +
* scons build yhi - Only build the interpretor.
  +
* scons build yhc - Only build the compiler.
  +
* scons build library - Only build the libraries.
   
To ensure you have the latest version of all the source, run:
+
Other commands available are:
  +
* scons clean - Remove temporary files.
  +
* scons fullclean - Completely wipe everything created by the build process.
  +
* scons depends - Download or update the dependencies

* scons help - Show a help message

You will need to have libraries like GMP (Gnu multi-precision arithmetic) installed. Most people do this with Fink or DarwinPorts, or some such. You need the header files in addition to the library archive, and these are often distributed in a 'devel' version of the package.
+
Then try building again.
   
If your packaging system uses a separate directory hierarchy (Fink uses /sw) then you may need to set up some environment variables so that the C compiler can find the includes and libraries:
+
== Build options ==
   
LD_LIBRARY_PATH=/sw/lib # for dylibs
+
"scons help" shows some options for the build process.
LIBRARY_PATH=/sw/lib # for static linking
 
CPATH=/sw/include # for header files
 
   
Then just follow the usual unix-like procedure, as above.
+
To build with additional library/header paths, e.g. for GMP:
  +
  +
CCFLAGS="-I/.../include" LIBPATH=/.../lib scons

Contents

[edit] 1 Requirements

You need a C compiler - both gcc and MS Visual C are known to be OK.

You need scons, which in turn requires Python to be installed. We require Python 2.3 or later to be installed.

The process of building Yhc requires ghc-6.4 or later and darcs.

[edit] 2 Getting the code

The source code is stored in a darcs repo, to get the code do:

darcs get --partial http://darcs.haskell.org/york-compiler98/
{- maybe darcs get --partial http://www.cs.york.ac.uk/fp/darcs/yhc/ is more recent? -}

There is a buildbot script that runs on every change, the results of which are available here. If the build is busted, hopefully the developers will fix it soon. If your build is busted, but the buildbot succeeds, consider adding your machine as a buildbot slave - then it will never get broken again.

[edit] 3 Building

To build yhc simply type 'scons' into a console Window. This should automatically detect your build environment and place the Yhc binaries into inst/

To build parts of Yhc separately the following commands can be used:

  • scons configure - Just configure.
  • scons build - Don't update dependencies, just build.
  • scons build yhi - Only build the interpretor.
  • scons build yhc - Only build the compiler.
  • scons build library - Only build the libraries.

Other commands available are:

  • scons clean - Remove temporary files.
  • scons fullclean - Completely wipe everything created by the build process.
  • scons depends - Download or update the dependencies
  • scons help - Show a help message

To test Yhc has been build correctly type 'scons test'.

Please report any problems you have to the mailing list.

Please also note that these steps do not currently build the Javascript backend; please refer to Yhc/Javascript/Users guide for information how to build ycr2js.

[edit] 4 Scons options

Options can be given to scons by either passing the flags on the command line 'core=1' or by creating a file called options.txt in the root Yhc directory. The available flags are:

  • core=1 (default=1) - generate Yhc Core files for each file in the libraries
  • arch=X86 (default=calculated) - override the arch, useful for building 32 bit version on a 64 bit kernel.
  • type=release/debug/normal (default=normal) - enables debug information or optimisation
  • threads=0 (default=1, except on ppc where the default is 0) - disables threading

[edit] 5 If something goes wrong

If the build fails for any reason, try the following steps:

; scons fullclean
; scons depends

Then try building again.

[edit] 6 Build options

"scons help" shows some options for the build process.

To build with additional library/header paths, e.g. for GMP:

CCFLAGS="-I/.../include" LIBPATH=/.../lib scons
