I'd really appreciate some help with this.
I have bucked up on this sort of issue b4 and it has come back to haunt me so I would like to better my understanding.

I'm trying to install a package that uses the gtk+-2.0 libs.
configure complains that `pkg-config --modversion gtk+-2.0` returns 2.6.10 but 2.6.9 is found.

How shall i re-educate pkg-config or remove 2.6.9 ?
I can't find any record of a gtk+-2.6.9

Thnks in advance

It has occasionally happened to me in the past that I have had two versions of a particular lib file installed at /usr/lib and at /usr/local/lib and/or two pkgconfig directories, one at /usr/lib/pkgconfig and the other at /usr/local/lib/pkgconfig, with pkg-config files for the two different lib files in each directory. It gets pretty frustrating when you know you have the right version installed, but pkg-config keeps finding the "wrong" one.

I recommend looking to see if you have two (or more) pkgconfig directories, and then if you do, determine if they each contain pkg-config files for gtk+-2.0.

When you do an `echo $PKG_CONFIG_PATH` what do you get? Does it include the path to the gtk+-2.0 pkg-config info for the 2.6.10 version? If not, you can use

`export PKG_CONFIG_PATH=/path/to/right/version:$PKG_CONFIG_PATH`

Hi
thnks for the response.

I do indeed have two pkgconfig directories as u described.


My million dollar question is ,.. u guessed it;how do I know which directory relates to which release of the 2.6* gtk libs ?

By the way,there was no enviirment variable set for PKG_CONFIG_PATH.

thnks

The gtk+-2.0*.pc files are text files, so you can read them with less, more or cat. They are also fairly self-explanatory, so you will be able to figure out pretty quickly which file belongs to which version.

Since you don't have a PKG_CONFIG_PATH set, you can set one using the export method I mentioned above. When you do, be sure that the first path you use in the expression is the one under which pkg-config will find the information for the version of gtk+-2.0 that you want. As you've already noticed, pkg-config stops looking as soon as soon as it finds a match for the program name, whether the version matches what you need or not.

i tried export PKG_CONFIG_PATH=/usr/lib/pkgconfig(for 2.6.10)

still same error.

so then I moved /usr/local/lib/pkgconfig(for 2.6.9) onto a usb hard drive.

still same.

I then set LD_LIBRARY_PATH to /usr/lib, and this fixed it !?

Thnks for setting me on the right path.(no pun intended.)

I just noticed that gtk+-2 went to version 2.8.11 in current, in case that matters to what you are compiling.

Glad you got it working.
