I've got a question regarding glib versions. I've installed glib 2.2.1 in order to compile gtk+ 2.2.1 and that went fine.
But now I'm trying to compile xmms and get an error:

checking for glib-config... no
checking for GLIB - version >= 1.2.2... no
*** The glib-config script installed by GLIB could not be found
*** If GLIB was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the GLIB_CONFIG environment variable to the
*** full path to glib-config.

Programs that need glib2 compile just fine.
glib2 works with pkgconfig afaik but glib1 doesn't.
If I compile glib 1.3.15 I get no glib-config file whatsoever
(due to pkgconfig I think), so how can I compile programs that need glib1 versions?

Okay - it depends where you installed Glib-1.3.15 to.

You need to search for it to make sure it is there. When I installed it, I ran:

./configure --prefix=/usr

followed by the usual to compile it. The prefix made glib install glib-config here:

/usr/bin/glib-config

If you didn't specify a prefix then you will find it at /usr/local/bin/glib-config
(BTW - I have a pkgconfig file for glib and glib-2.0).

Once you have located it, check your $PATH variable to include the directory it is held, like so:

echo $PATH

Which should show you something like this (here's mine):

.:/home/cmarch/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/opt/bin
:/opt/gnome/bin:/opt/gnome2/bin:/opt/java/j2sdk-1.4.1/bin:
/home/cmarch/test/usr/bin

You can add a directory to $PATH by typing:

export PATH=$PATH:/any/directory/bin

Obviously changing the directory! You are using LFS right? Which version? And have you followed the BLFS book for compiling xmms?

That's it, it doesn't make nor install that glib-config file.
My PATH does point to those directories but I don't understand why it's not generating that config file.
I'm using 4.0 and I did have a look at BLFS but I still don't get why that file isn't been generated (I said that already)

If it's not there - and you have searched for it - then the only thing you can do is re-install glib.

But to me it is odd for it not to be installed - have you compiled any other programs that use glib-1*???

It's ok now, installed glib-1.2.10 and that works perfectly.
I reinstalled the other one a dozen times, but as long as I don't need it, things can be done with 1.2.10.
