Configure breaks by build

[Sascha Manns]

Hello list,

i'm preparing some autotools files for my new project.

I have in my configure.ac:

GDK30_MINIMUM_VERSION=2.99.0
GTK30_MINIMUM_VERSION=2.99.0
ATK_MINIMUM_VERSION=2.99.0

PKG_CHECK_MODULES(gdk-3.0 >= $GDK30_MINIMUM_VERSION
                  gtk+-3.0 >= $GTK30_MINIMUM_VERSION
                  atk >= $ATK_MINIMUM_VERSION)

After running the autogen.sh i'm getting:

configure.ac:48: error: AC_SUBST: `gdk-3.0 >= $GDK30_MINIMUM_VERSION 
                  gtk+-3.0 >= $GTK30_MINIMUM_VERSION
                  atk >= $ATK_MINIMUM_VERSION_CFLAGS' is not a valid
shell variable name

But what to do now?

Greetings
Sascha

Try instead

m4_define([GDK30_MINIMUM_VERSION], [2.99.0])
m4_define([GTK30_MINIMUM_VERSION], [2.99.0])
m4_define([ATK_MINIMUM_VERSION], [2.99.0])

PKG_CHECK_MODULES([
gdk-3.0 >= GDK30_MINIMUM_VERSION
gtk+-3.0 >= GTK30_MINIMUM_VERSION
atk >= ATK_MINIMUM_VERSION
])

I don't know that this will work, but it looks like PKG_CHECK_MODULES
can't handle shell variables in its argument, so the obvious thing is
to try m4 variables instead.

That one works. Thank you very much.

Hello list,
i'm preparing some autotools files for my new project.
GDK30_MINIMUM_VERSION=2.99.0
GTK30_MINIMUM_VERSION=2.99.0
ATK_MINIMUM_VERSION=2.99.0
PKG_CHECK_MODULES(gdk-3.0 >= $GDK30_MINIMUM_VERSION
gtk+-3.0 >= $GTK30_MINIMUM_VERSION
atk >= $ATK_MINIMUM_VERSION)

The autoconf package does not maintain the PKG_CHECK_MODULES() macro, so
your question is probably better asked on the pkg-config development
list. However, it appears to me that you are getting an error because
your usage of the macro is incorrect. Here's an example I picked up
from a package that uses the macro correctly:

PKG_CHECK_MODULES([LIBNL_ROUTE3], [libnl-route-3.0])

which makes it look like you forgot a first argument.
