Title: Which includes to use for C compilers
Post by: asrael22 on June 20, 2024, 08:23:57 PM

Hi.

Most C compilers (vbcc, sas/c, etc). come with their own set of Amiga includes.
But there is also the AOS NDK includes.
How should this be used? Does one should have precedence over the other?

I have been setting this up as assigns where the NDK includes/libs are first and then the compiler specific includes ADDed to the assign.
Is this the right way?


Cheers

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.

Alright, thanks.

When you say "I prefer to replace NDK inlines with compiler provided ones", what do you mean with 'replace' here, how do you replace them?

I've checked, SAS/C actually comes with a full set of Amiga headers, probably 3.1 based.
VBCC does not.

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.
