error #20: identifier "float_round_style" is undefined

Hi,

While trying to build on HP-UX B.11.23 U ia64, using thirdparty front end to compile, I am getting the following error:

"/usr/include/math.h", line 1147: error #77-D: this declaration has no storage
class or type specifier
__inline float fabsf(float __x) { return _Asm_fabs(__x); }

In addition, I have provided the following includes while builing the front end compiler using aCC 6.15.

#if defined(__ia64)
v_argv[n++] ="-I/opt/aCC.06.15/opt/aCC/include";
v_argv[n++] ="-I/opt/aCC.06.15/opt/aCC/include/iostream";
v_argv[n++] ="-I/opt/aCC.06.15/opt/aCC/include_std";
v_argv[n++] ="-I/usr";
#endif

Any suggestion would be appreciated.

Regards,
Neel

Unless your third party preprocessor matches exactly with what aCC6 is doing, you'll continue to have problems like this and your previous threads:

>error #77-D: this declaration has no storage class or type specifier
__inline float fabsf(float __x)

Just pass in -D__inline=inline.

>error #20: identifier "_Asm_fabs" is undefined

All _Asm_* functions are builtin.

>/opt/aCC.06.15/opt/aCC/include/limits: error #20: identifier "float_round_style" is undefined
static const float_round_style round_style;

I'm not sure what's wrong here? You should be using the includes from include_std. float_round_style should be defined before use.

#if defined(__ia64)
"-I/opt/aCC.06.15/opt/aCC/include";
"-I/opt/aCC.06.15/opt/aCC/include/iostream";
"-I/opt/aCC.06.15/opt/aCC/include_std";
"-I/usr";

These are incorrect. There shouldn't be any #if. There needs to be a set for -AP and another set of -AA. The above set is a miss mash of the two.

Use -v to see the paths for -AA (the default) and -AP.

Thanks for reply.

I will try to defined the above declaration for thirdparty.
