It's quite straight-forward to split up the %.hsc-%.hs rule in two, the first one generating %_hsc_make with a cross-compiler, the second one moving the binary over to the target, executing it and piping the result into %.hs. Compiling on the target is certainly feasible, too, but I happen to have a working cross-compiler. I am, however, stuck with make, in the area of separating the build directories into stage1/stage2 for the libraries as well as transferring ./configure output over from the target to the build platform, without having that trigger recompilation of stage1 (and the package info being a bit messed up wrt. -l flags, but that's a minor concern) Compiling the stage2 libraries with actual target info also opens up the issue that we can't use the native gcc as it's quite likely to fail, not so much while compiling (at least .hc), but linking: My linux doesn't come with libutil, for example. Both using a cross-gcc and replacing gcc with touch should work, I've not had much time to investigate this. The main issue, however, is that we're infecting perfectly cross-platform .hc with platform-specific information by preprocessing Haskell instead of C: It might be feasible to generate C stubs for all hsc2hs macros and calling them via the ffi, leaving resolving of platform-specific things until later. The whole build-process depending on .o s being generated even when all you want to have are .hc s isn't helping things. And then there's David's LLVM work... I'm currently slurping his thesis because porting via LLVM looks very, very, elegant and painless, at least from afar. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/3472#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

through .hc files broken
Comment:
{{{make[1]: *** No rule to make target `rts/dist/build/Apply.o', needed by
`rts/dist/build/libHSrts.a'. Stop.}}}
I've encountered the same, I moved all .hc files to .c files, including
AutoApply.hc, which lives in dist. Seems to work out fine.
the NO_REGS/MINI_INTERPRETER issue is fixed in 6.12.0-rc1.
the primopcodes are copied over from the host according to the port
process docs, but the build system doesn't get that they're already there
and tries to build genprimopcode, anyway. I nuked the respective make
rules, and stuff seems to work out fine (that is, it compiles).
I've also encountered various linker issues (and missing symbols
beforehand, as haiku e.g. doesn't come with siginfo_t), but I guess these
are quite normal while porting to a new platform. A stub for getlocale
won't hurt the system, too.
I've also experienced segfaults in Data.List.last, but can say that ghc
would have failed differently, anyway, due to wrong args etc.
However, there's two very, very important bits missing to the porting
process:
1) Hs*Config.h (those for the libraries) aren't taken from the target
system, but the host while generating .hc's (I'm looking into making the
build system eat them, the naive approach didn't work (made make error out
due to looping))
2) the intermediate .c files generated from .hsc files are compiled with
the host's headers (which leads to fun bugs like ghc being confused about
what consists a directory and what not, due to struct stat having a
different layout). This can either be fixed by moving the intermediate
files onto the target and compile+run them there (which is awkward), or
pre-processing them on the host using the target's headers, then
compiling+running them on the host (which is convenient, and should be
safe to do). Another possibility, of course, is to switch to c2hs, which
knows of cross-compiling.
I've also had issues with too big constants in .hc files, but instead of
investigating the source, I switched to a 32-bit chroot for my host.
I'm going to flag my other bug as a duplicate of this.
