Patch: change RTS to work with ARM EABI
by Brian McKenna 10 Jul '11

10 Jul '11

I've attached a Darcs patch to make compilation work with arm-eabi-gcc (uses the defined __ARM_EABI__). This lets me compile to Nintendo DS! http://twitpic.com/5nsjzy Thanks, Brian McKenna

JHC fails to build with ghc 7.0.3
by Robert Clausecker 02 May '11

02 May '11

Hello all! I recently upgraded my development platform to GHC 7.0.3 and the latest platform. After manually patching the cabal package for DrIFT (it had a dependency base<4 which was not satisfiable on my system, so I changed it to base-all) I tried to build jhc. Both version 0.7.7 fail to build, but there are different reasons: - -XTypeFamilies is required to build JHC with GHC 7.0.3, so I added this flag to Makefile.am - jhc 0.7.7 fails to build at the module "Options" with the following error message: [ 73 of 169] Compiling Options ( drift_processed/Options.hs, src/Options.o ) src/Options.hs:396:19: Couldn't match expected type `[Char]' with actual type `Char' Expected type: [String] Actual type: [Char] In the second argument of `(==>)', namely `version' In the expression: "version" ==> version - jhc TRUNK fails at E.SSimplify with a rather long error, so I put it onto a paste service: http://goo.gl/tpKvZ I hope these errors are helpful. Yours, Robert Clausecker

Strange error message when using Parsec
by Dr. ERDI Gergo 11 Feb '11

11 Feb '11

Hi, I'm trying to use jhc with Parsec. However, while reimplementing some Parsec.Token functionality, I've encountered a strange error message. I've created a hopefully minimal example (see attached). The error message for this particular version (using the latest version from darcs or the 0.7.7 release): jhc -flint -p parsec-2.1.0.1 -o parsec-error.jhc parsec-error.hs jhc 0.7.7 (0.7.7-14) Finding Dependencies...

ANNOUNCE: jhc 0.7.7 is out.
by John Meacham 31 Jan '11

31 Jan '11

Announcing jhc 0.7.7! This release fixes a large number of bugs that cropped up when compiling haskell out in the wild as well as adds some more features. A major one being the garbage collector is enabled by default. http://repetae.net/computer/jhc/ Changes: (including some changes from the unannounced 0.7.6 release) * The Garbage Collector is now enabled by default. * new standard libraries * transformers * parsec * QuickCheck * report proper errors with line numbers for various issues with compiled code. * New option '-C' that compiles to C code and stops, useful for targeting other platforms or building shared libraries. * Nintendo Wii added as target (thanks to Korcan Hussein) * Fix major performance bug that kept WRAPPERs from being inlined in certain places. * Typechecking speed greatly increased. * monomorphism-restriction flag is now respected * empty class contexts now work * unicode in haskell source supported now * Type Defaulting now works properly * RULES parse like ghc now for compatibility * 'do' 'where' on same indent now parses * Build system fixes and cleanups * irrefutable lambda pattern bindings desugar properly now. * GHC parsing regression tests have been ported to jhc, helped find and fix many bugs. * Certain optimizations would discard RULES, these have been fixed. * Removed quadratic behavior in optimizer, speeds things up noticibly. * Garbage collector improvements, caches are pre-initialized. * Fix shiftL/R implementations for built in types. * All Num, Real, and Integral magic removed from compiler. This is a very good thing. * improved help messages John
