Top Forums Programming how to create variable for all thread in c++ Post 302311059 by Corona688 on Monday 27th of April 2009 08:02:58 PM

The compiler may have optimized it away. It sees 'hmm, this value never changes! Therefore I can assume it is a hardcoded zero' and does so. If you instead declare it as 'volatile int var1' then the compiler will not make such assumptions.

NAME
g-ir-compiler - typelib compiler. SYNOPSIS
g-ir-compiler [OPTION...] GIRFILE DESCRIPTION
g-ir-compiler converts one or more GIR files into one or more typelib. It can either emit the raw typelib blob (default behavior) or C code (--code). The output will be written to standard output unless the --output is specified. OPTIONS
---help Show help options ---code Emit C code which is suitable for including in a shared library instead of a raw typelib. ---output=FILENAME Save the resulting output in FILENAME. ---verbose Show verbose messages ---debug Show debug messages ---no-init Do not include an initialization snippet to register the typelib in the respository. This can only be used if --code is also speci- fied. ---includedir=DIRECTORY Adds a directory which will be used to find includes inside the GIR format. ---module=MODULE FIXME ---shared-library=FILENAME Specifies the shared library where the symbols in the typelib can be found. The name of the library should not contain the leading lib prefix nor the ending shared library suffix. BUGS Report bugs at http://bugzilla.gnome.org/ in the glib product and introspection component.
