Build fail on MacOSX 1.4.5

Hello, been trying tobuild ghc from scratch (I'd like to fiddle with its code). I work on a PowerBook Mac under version 1.4.5 of MacOSX and the compile failed on the 1.4.2 sources from the haskell.org/ghc site. Strangely, this seemed also to be a bug on MacOSX 1.3.9 and a bug tracking report told me it was fixed. So what happened here? Can anybody help me out? Please reply to this message, since I am not a member of this group (yet). The output of the compiler is this: ...lots of stuf omitted... ------------------------------------------------------------------------ /usr/local/bin/ghc -H16m -O -istage1/utils -istage1/basicTypes - istage1/types -istage1/hsSyn -istage1/prelude -istage1/rename - istage1/typecheck -istage1/deSugar -istage1/coreSyn -istage1/ specialise -istage1/simplCore -istage1/stranal -istage1/stgSyn - istage1/simplStg -istage1/codeGen -istage1/main -istage1/ profiling -istage1/parser -istage1/cprAnalysis -istage1/compMan - istage1/ndpFlatten -istage1/iface -istage1/cmm -istage1/nativeGen -istage1/ghci -Istage1 -DGHCI -package template-haskell -package readline -DUSE_READLINE -cpp -fglasgow-exts -fno-generics -Rghc- timing -I. -IcodeGen -InativeGen -Iparser -package unix -ignore- package lang -recomp -Rghc-timing -H16M '-#include "hschooks.h"' - i../lib/compat -ignore-package Cabal -c utils/PrimPacked.lhs -o stage1/utils/PrimPacked.o -ohi stage1/utils/PrimPacked.hi utils/PrimPacked.lhs:250:0: Warning: foreign declaration uses deprecated non-standard syntax utils/PrimPacked.lhs:254:0: Warning: foreign declaration uses deprecated non-standard syntax utils/PrimPacked.lhs:257:0: Warning: foreign declaration uses deprecated non-standard syntax utils/PrimPacked.lhs:260:0: Warning: foreign declaration uses deprecated non-standard syntax utils/PrimPacked.lhs:263:0: Warning: foreign declaration uses deprecated non-standard syntax In file included from /tmp/ghc29849.hc:5: /usr/local/lib/ghc-6.4.1/include/HsUnix.h: In function '__hsunix_rtldNext': /usr/local/lib/ghc-6.4.1/include/HsUnix.h:103: error: 'RTLD_NEXT' undeclared (first use in this function) /usr/local/lib/ghc-6.4.1/include/HsUnix.h:103: error: (Each undeclared identifier is reported only once /usr/local/lib/ghc-6.4.1/include/HsUnix.h:103: error: for each function it appears in.) /usr/local/lib/ghc-6.4.1/include/HsUnix.h: In function '__hsunix_rtldDefault': /usr/local/lib/ghc-6.4.1/include/HsUnix.h:107: error: 'RTLD_DEFAULT' undeclared (first use in this function) <<ghc: 49082080 bytes, 10 GCs, 1539742/2981452 avg/max bytes residency (2 samples), 17M in use, 0.13 INIT (0.00 elapsed), 0.54 MUT (1.13 elapsed), 0.25 GC (0.36 elapsed) :ghc>> make[2]: *** [stage1/utils/PrimPacked.o] Error 1 make[1]: *** [all] Error 1 make: *** [build] Error 1 cheers, Jur(riaan Hage)

Error in shutdownHaskell() in Win32 DLL

If an exception occurs in a Windows DLL produced by GHC, the following error message appears: ghcDll: internal error: too many hs_exit()s Please report this as a bug to glasgow-haskell-bugs@xxxxxxxxxxx, or http://www.sourceforge.net/projects/ghc/ How to reproduce ---------------- 1. Make a Haskell DLL using the enclosed Dll.hs and dllMain.c, e.g. ghc -c Dll.hs -fglasgow-exts ghc -c dllMain.c ghc --mk-dll -o test.dll Dll.o Dll_stub.o dllMain.o 2. Generate an export library for the DLL, e.g. lib /DEF:test.def /MACHINE:x86 /OUT:test.lib 3. Compile the executable with Visual C++ and run it. cl -c testdll.cpp link testdll.obj test.lib /OUT:testdll.exe testdll.exe Note: if I comment out the shutdownHaskell() call from dllMain.c (the line marked with /***/), it works fine. Kind regards, Cyril --- Dll.hs --- module Dll (test) where foreign export ccall test :: IO () test = error "Exception occurred" --- dllMain.c --- #include <windows.h> #include <Rts.h> extern void __stginit_Dll(void); static char* args[] = { "ghcDll", NULL }; BOOL STDCALL DllMain ( HANDLE hModule , DWORD reason , void* reserved ) { if (reason == DLL_PROCESS_ATTACH) { startupHaskell(1, args, __stginit_Dll); return TRUE; } else if (reason == DLL_PROCESS_DETACH) { /***/ shutdownHaskell(); } return TRUE; } --- test.def --- EXPORTS test --- testdll.cpp --- extern "C" void test(); int main() { test(); return 0; }
