Hi all,
I am the new bie in NetBsd forum, For one of the my requirement,
I am trying to build NetBsd3.1 math library (Libm), But while building
libm I am getting
following build error :
s_isinf.c:19: error: expected identifier or '(' before 'sizeof'
s_isinf.c:19: error: expected ')' before '?' token
This error is comming because of " __fpmacro_unary_floating " define in
math.h as follows
#define __fpmacro_unary_floating(__name, __arg0)
\
/* LINTED */
\
((sizeof (__arg0) == sizeof (float))
\
? __ ## __name ## f (__arg0)
\
: __ ## __name ## d (__arg0))
and
#define isinf(__x) __fpmacro_unary_floating(isinf, __x)
The definations of isinf() present under src/lib/libm/src/isinf.c
I guess, this error is comming because of compiler not able to recognise
the
above ternary operator because if I defined it directly
#define isinf(__x) __isinfd(__x)
without __fpmacro_unary_floating macro, its working fine.
So,is it the issue with compiler ? then how to resolve it ?
Can anybody tell me which gcc compiler using for NetBsd3.1 ?
Please guide me in this respect. Waiting for reply .......
Thank You,
Amol Pise
