Accodring to the man page of cpp there is -nostdinc. But even after trying it,
the problem remains.

h2pas only does the simple direct stuff.
All the rest needs manual replacement.
As much as I know unsigned corresponds to unsigned int.
static inline seems to be the problem.
Example (line 393):
static inline unsigned NI_USUAL_PFI_SELECT(unsigned pfi_channel)
{
if(pfi_channel < 10)
return 0x1 + pfi_channel;
else
return 0xb + pfi_channel;
}
unsigned int NI_USUAL_PFI_SELECT(unsigned int pfi_channel);
there are about 15 similar cases. At least this gives a start.
Maybe you need a translation of the function in the implementation section.
You may also need to add functions for the macros in /* range stuff */ and /*
packs and unpacks a channel/range number */
check for " { was #define dname(params) para_def_expr } " in the resulting .pp
file.
Finally, I prefer to use ctypes. So, unsigned int becomes cuint, float cfloat
and so on. It makes checking easier.
