Which includes to use for C compilers

[krashan]

Not sure about SAS/C, but VBCC does not come with includes replacing the NDK. Same for GCC. Usually compiler provides headers for C standard library and interface to AmigaOS API (it may be set of files in 'inline' or 'pragma' directory, someties with a static library). Definitions of AmigaOS structures come from the NDK. The NDK itself contains inline files too, which try to be universal. I prefer to replace NDK inlines with compiler provided ones, then place NDK includes in the include search path of the compiler.

what do you mean with 'replace' here, how do you replace them?

I replace them literally. Delete original ones and copy my files there.
Inline files in the NDK 3.2 are quite good and work with most of C compilers. However they are incompatible with GCC 2.95.3 compiler used in C++ mode. This was my reason to replace them.

GCC 2.95.3 does not support placing function arguments in specified CPU registers when in C++ mode. One has to resort to placing local variables in specified registers. For example

Code: [Select]

LONG foo(LONG argument __asm("d0"))
works in C mode, but not in C++ mode. However

Code: [Select]

LONG foo(LONG argument)
{
  register LONG _argument __asm("d0") = argument;
works in both modes.
