Bug #5491: build failure on Tru64 UNIX 5.1

• Status: Closed
• Assignee: -
• Target version: 1.9.2
• ruby -v: UNKNOWN

Building 1.9.2 with latest svn revision at 33531 produces a build error because <c_except.h> defines leave and except:
/* definitions of keywords and intrinsic function names */
#ifndef __cplusplus
#define try __builtin_try
#endif
#define except __builtin_except
#define leave __builtin_leave
#define finally __builtin_finally

• File patch patch added

I understand the problem, but the patch is hard to merge.
What header includes c_excpt.h?
I want to undef them just after including a header.

[twwlogin (The Written Word Inc)]

For compile.c, we have:
#include "ruby/ruby.h"
#include "vm_core.h"
#include "thread_pthread.h"
#include <pthread.h>
#include <pthread_exception.h>
#include <c_excpt.h>

So, if you #undef leave and #undef except after #include <pthread.h> in thread_pthread.h, that's a solution as well.

You mean this?

Yes, that should work.
