FFI Addendum Typo

In subsubsection 4.1.5 C Argument Promotion, the C example function void foo (a) { float a; ... } should instead read void foo (a) float a; { ... } The former declares a local variable that shadows the parameter. Cheers, Wolfgang

I just wanted to remove the inquiry from the newsgroup list. The build was originally with cygwin tools and libraries, on the C/C++ side, which caused big trouble. Now MinGW is used, and everything does fit together. Thank you for your attention Hans > > Cheers, > Simon >

Could you describe in more detail exactly what you're doing? We need to know: - what version of GHC - what platform - the exact command lines you used - if possible, a copy of the code so we can reproduce the problem Cheers, Simon

Errors from Haskell, C/C++ Objects Linkage

When linking a program with Haskell Code (also the main program), and interfacing to C functions (a lib*.a C++ application library is also combined), the following error occurs: c:/ghc/ghc-6.0/libHSrts.a(Main.o)(.text+0x86):Main.c: undefined reference to `__stginit_Main' c:/ghc/ghc-6.0/libHSrts.a(Main.o)(.text+0x9b):Main.c: undefined reference to `Main_zdmain_closure' In the contrary, the error does not occur when linking a few functions to the Haskell Main only. Comments welcome ! H. Groh <<Groh, Hans.vcf>>
