Description Raimund Steger 2011-11-13 22:55:38 UTC 
When compiling gtk+-3.0.12 with Solaris Studio 12.2 on Solaris 10 x86, I get the following error:

  "/usr/include/sys/feature_tests.h", line 332: #error: 
  "Compiler or options invalid for pre-UNIX 03 X/Open applications 
  and pre-2001 POSIX applications"
  cc: acomp failed for gtksearchenginesimple.c

It works after I apply:


--- ./gtk/gtksearchenginesimple.c.orig	Sun Nov 13 20:58:42 2011

-#define _XOPEN_SOURCE 500
+#define _XOPEN_SOURCE 600
 #define _GNU_SOURCE 
 
 #ifdef HAVE_FTW_H


However, I'm not sure about the implications of making this change on other platforms.

I run the build with -std=c99, which is what the default was.

Not limited to Solaris Studio compiler, also with gcc the same happpens.  C99 implies at minimum _XOPEN_SOURCE=600.
