I use gmrender with my old chumby that has glib 2.18.

Every time I need to recompile I've to apply a simple patch in order to
support old way of initializing thread in glib

What is happening with the old glib ? Does it not have the symbols, or does
the code break ?

In general, sounds good, I'll have see that I can get that applied later
tonight.
It looks like you're comparing against a particular version of glib, this
should probably be a less-than/larger-than thing ? Can you figure out the
exact cut-off version for me ?

Thanks,
Henner.

Here the snippet if you really want I can do a merge request:

It doesn't have the 'g_thread_get_initialized' function (introduced in glib 2.20) but only the g_thread_supported () [1]

According to the docs g_thread_init wasn't necessary anymore from 2.32 [2]

Regarding the check the name of the macro is a bit measleading but the docs says:

TRUE if the version of the GLib header files is the same as or newer than the passed-in version.

Last but not least, I had to move function call at the beginning of the main function to prevent some gstreamer 0.10 warning (or error? I don't remember exactly) even when just parsing the options without threads initialized.
