Bug #1236: RUBY_VERSION not defined

• Status: Rejected
• Assignee: -
• Target version: 1.9.1
• ruby -v: ruby 1.9.2dev (2009-03-01) [i386-mswin32_90]

Building from trunk with MSVC 2008.

ruby/config.h is generated with this line:

#define RUBY_LIB_VERSION STRINGIZE(RUBY_VERSION_MAJOR)"."STRINGIZE(RUBY_VERSION_MINOR)"."STRINGIZE(RUBY_VERSION_TEENY)

But RUBY_VERSION_MAJOR, RUBY_VERSION_MINOR, RUBY_VERSION_TEENY are not defined in this file or in any file that is installed. They are defined in trunk/version.h but that is not installed.

Nor is RUBY_VERSION defined.

This is an issue because libxml-ruby uses st.h, and thus needs code that looks like this:

#if RUBY_VERSION < "1.9.0"
#include <st.h>
#else
#include <ruby/st.h>
#endif

Right now that doesn't work because RUBY_VERSION is not defined.

Actually, the code would be more like this:

#if RUBY_VERSION_MAJOR == 1 && RUBY_VERSION_MINOR < 9
#include <st.h>
#else
#include <ruby/st.h>
#endif

However, to do that with Ruby 1.8.6 appears to require including version.h, which doesn't appear to exist in Ruby 1.9.1. So how should this be done?

It's only for the purpose to initialize the load path. You
never use that macro.

This is an issue because libxml-ruby uses st.h, and thus needs code that looks like this:

#include <ruby.h>
#ifdef HAVE_RUBY_ST_H

include <ruby/st.h>

#else

include <st.h>

#endif
