Description Yeti 2005-12-12 23:42:50 UTC 
gtk-doc.m4 only invokes any AC_MSG_CHECKING() when all following conditions are met:

* gtk-doc was already found via pkg-config
* version check is requested

Therefore when for example gtk-doc.pc is not found, it looks like configure did
not attempt to check for gtk-doc at all.  This is quite confusing.
Comment 1 Stefan Sauer (gstreamer, gtkdoc dev) 2006-03-21 11:12:09 UTC 
but if there is no gtk-doc.pc, than this should mean that there is no gtk-doc at all. What scenario can you imagine where gtk-doc has been installed without gtk-doc.pc.
Comment 2 Yeti 2006-03-21 11:21:27 UTC 
If configure comes to conslusion there is no gtk-doc.pc (and thus no gtk-doc), then it checked for gtk-doc.  Therefore I expect it to print:

Checking for gtk-doc... no

What scenario can you imagine configure can determine presence or absence of some package without checking for it?

I submitted a patch to bug 450338 that fixes this issue among other things.

Yeti, is the patch in bug #450338 fine for you too?

At the expense of calling pkg-config twice, yes, as one gets a diagnostics when gtk-doc is not installed at all.

What do you mean? If anything my patch removes calling pkg-config twice.

Sorry, too early in the morning, not enough coffee...
