This is with glib-1.2.10-5.
Anyone know anything about glib's G_LOCK_DEFINE_STATIC? I have an app
that uses it like so:
/* this mutex provides a lock for stdout to avoid display conflict
between thread */
G_LOCK_DEFINE_STATIC(stdout); <--- line 39
G_LOCK(stdout); <--- line 137
And it won't compile:
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I/sw/include/glib-1.2
-I/sw/lib/glib/include -no-cpp-precomp -c display.c
display.c:39: parse error before `&'
display.c: In function `disp_msg_full':
display.c:137: parse error before `_lock'
display.c:137: parse error before `_lock'
The relevant part of glib-1.2/glib.h. All this preprocessor stuff is
almost as confusing as libtool. Theres a reason they say "The C
preprocessor is very powerful. Never use it." :)
That "## name ##" part looks bad.. is that correct?
/* these are some convenience macros that expand to nothing if GLib
* was configured with --disable-threads. for using StaticMutexes,
* you define them with G_LOCK_DEFINE_STATIC (name) or G_LOCK_DEFINE (name)
* if you need to export the mutex. With G_LOCK_EXTERN (name) you can
* declare such an globally defined lock. name is a unique identifier
* for the protected varibale or code portion. locking, testing and
* unlocking of such mutexes can be done with G_LOCK(), G_UNLOCK() and
* G_TRYLOCK() respectively.
