Bug 62288

What do you mean, exactly? 
 
In the generated Makefile, do you see that symbol be defined? Or is it a problem with the 
GUI?

I've just checked admin/acinclude.m4.in. There's no test for LIB_KDEGAMES there. It's only 
defined if you add this to your configure.in.in: 
 
if test -d $srcdir/libkdegames ; then 
        AC_SUBST(LIB_KDEGAMES, "\$(top_builddir)/libkdegames/libkdegames.la") 
        AC_SUBST(LIB_KDEGAMES_DEP, '$(LIB_KDEGAMES)') 
else 
        AC_SUBST(LIB_KDEGAMES, "-lkdegames") 
        AC_SUBST(LIB_KDEGAMES_DEP, "") 
fi 
 
(taken from kdegame's configure.in) 
 
Still, the wish for Gideon checking of entered parameters is valid. Gideon will have to scan 
the generated Makefile.in to see if it's defined and warn if not. 
 
(yes, it's a wishlist item; it's a feature that doesn't exist) 

Sorry, this is not possible at all. The autoconf stuff is a jungle of 
shell-scripts, there is no way we can find out which variables are set or not. 
If you want less brain-damage, please tell the automake/conf guys to fix their 
system and make it more transparent. 

/me points Harald to autoconf --trace=AC_SUBST

Exactly my problem, Harald ... "jungle" is a good word ... or perhaps it's
like Schrodinger's cat.  From a developer's point of view, you cannot tell
if your application is alive or dead until you open the box (i.e. try to
build and run it).  That's why I'm looking to KDevelop to provide some
early diagnostics of undefined's in the "make" environment.

Please do.  I don't know who or where they are.  Here are some stats ...
2319 lines of Makefile's for a minimal KDE application (with source
code as generated by Gideon): 404 lines of Makefile's to compile and
build the entire Qt 3.0.2 library, examples, tutorials and non-trivial
apps like QDesigner (using QMake) ... and the Makefile's are such that
even I can understand them.  I am thinking of writing an article entitled
"Automake considered harmful", echoing Dijkstra's classic about GOTO.

Harald, KDevelop itself generates the "auto4te" subdir, with file
"traces.0", which contains evaluations of all the LIB_ symbols and
lots of other stuff too, but, as expected, LIB_KDEGAMES is
not there.  I have defined it in my Shell env now, so perhaps
KDevelop should also check there when validating input.

I would say that whoever maintains those macros should add
LIB_KDEGAMES, since it is now a standard KDE library.

Please reconsider my problem.  I am sure you can add some
needed input validation with little effort.  My other request, for a
list of commonly used symbols and their current assignments, should
not be hard to implement either.  See bugs 62289 and 62291.
