Subject: [ruby-core:68376] [Ruby trunk - Bug #10906] Problem building on Solaris 10 - symbol rb_infinity not found

Issue #10906 has been updated by Naohisa Goto.


Thanks.
The output of the commands suggest that the macro INFINITY was defined when compiling numeric.c but was not defined when compiling ext/date/date_core.c.
I still couldn't find why.

INFINITY is C99 feature, and whether INFINITY is already defined or not is checked in include/ruby/missing.h: 

~~~
#ifdef INFINITY
# define HAVE_INFINITY
#else
/** @internal */
RUBY_EXTERN const union bytesequence4_or_float rb_infinity;
# define INFINITY (rb_infinity.float_value)
#endif
~~~

The concrete definition of rb_infinity is in numeric.c:

~~~
#ifdef HAVE_INFINITY
#elif !defined(WORDS_BIGENDIAN) /* BYTE_ORDER == LITTLE_ENDIAN */
const union bytesequence4_or_float rb_infinity = {{0x00, 0x00, 0x80, 0x7f}};
#else
const union bytesequence4_or_float rb_infinity = {{0x7f, 0x80, 0x00, 0x00}};
#endif
~~~

Hi,

Solaris 10
gcc 4.8
ruby 2.2.0 current stable

I did configure/make, and it works until it tries to generate rdoc:
