I'm trying to install gtk+ 2.6.1 and it ask me for glib, atk and pango. I'd installed glib 2.6.1 but when i install pango it gives me this error:

checking for GLIB - version >= 2.5.7... no
*** Could not run GLIB test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GLIB is incorrectly installed.
configure: error:
*** Glib 2.5.7 or better is required. The latest version of
*** Glib is always available from ftp://ftp.gtk.org/.

I'd installed glib by this way:
$ configure --prefix=/usr
$ make
# make install

I'm using SUSE 9.0

Thanks.

try as root to run the command
ldconfig
and see if that helps

I'd tried with ldconfig, but nothing happens. How can i use this command?? I put it in the command line and run it. I think it's something like this "/folder_location/ ldconfig". But i don't know the location of glib.

Thanks

What's the output of echo "LD_LIBRARY_PATH" ? If it isn't "/usr/local/lib:/lib:/usr/lib:/usr/X11R6/lib", the following commands (as root) may fix your problem.

I do exactly what you told me, but it gives me same error.

The output mentions config.log will show the exact error, what does config.log say?

Thomas

Do you have /usr/lib/pkgconfig in your PKG_CONFIG_PATH variable and /usr/lib in your LD_LIBRARY_PATH variable?

Yes, i have the two variable

The config.log show this:

configure:21613: checking for GLIB - version >= 2.5.7
configure:21762: result: no
configure:21795: gcc -o conftest -g -O2 -Wall conftest.c >&5
conftest.c:27:18: glib.h: No such file or directory
conftest.c: In function `main':
conftest.c:33: error: `glib_major_version' undeclared (first use in this function)
conftest.c:33: error: (Each undeclared identifier is reported only once
conftest.c:33: error: for each function it appears in.)

conftest.c:33: error: `glib_micro_version' undeclared (first use in this function)
configure:21801: $? = 1

if your just exporting the LD_LIBRARY_PATH and not the PKG_CONFIG_PATH it will probably fail due to picking up the libraries out of /usr/local/include but using the headers elsewhere. ( which will give you undefined reference/symbol errors)

This is what i'm doing:

# LD_LIBRARY_PATH=/usr/local/lib:/usr/X11R6/lib:/usr/lib
# export LD_LIBRARY_PATH
# ldconfig
# PKG_CONFIG_PATH=/usr/lib/pkgconfig/
# export LD_LIBRARY_PATH
# ldconfig

I don't know what does this code do, but "twsnnva" told me to do that.
It's that right????
Still don't work.

I don't know, it depends on where you installed glib to. technically:

PKG_CONFIG_PATH=/usr/lib/pkgconfig

won't do anything except overwrite the rest of the PKG_CONFIG_PATH the distro sets up and b0rking any chances you have of compiling anything.

so:

don't use LD_LIBRARY_PATH for what your doing. just make sure /usr/local/lib is listed as one of the directories in /etc/ld.so.conf and run ldconfig as root (which will eliminate the need for LD_LIBRARY_PATH in this example)

then:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

if your new glib is installed in the prefix /usr/local. what this does is set /usr/local/lib/pkgconfig to the FIRST directory pkg-config will search ( if you have an old glib in /usr this is why your running into problems, but we can get around that now but you will have to set LD_LIBRARY_PATH at runtime or the program will bail).

so try these and tell me:

1). where is the new glib at?

2). do you have an old glib that came with your system installed somewhere else?

This problem is easy to solve as I had the exact same problem. What you do is install GLIB to /usr, and install ATK and pango and GTK to /usr, assuming you are trying to install GTK.

[code]
./configure --prefix=/usr
[/code[

su
make
make install

BAM! You're set.

Thanks "Micro420" but it doesn't work.

1) I think the new glib it's at "/usr/local/include/glib-2.0/glib"

2) I run "rpm -q glib" and it appears this: glib-1.2.10-482 (this one come with my distro)
I've tried to uninstall it but i don't know how. I write (as root) "rpm -e glib-1.2.10-482" but nothing happens, i think because of some programs that use the libraries

I think that "./configure" install glib in "/usr/local/include/glib-2.0/glib", and if i put "./configure --prefix=/usr" it's going to install glib in "/usr/include/glib-2.0/glib"

did you install glib-2.x ( your gonna need 2.6.0 at least for gtk-2.6 I think)?

glib-1.2.x is the older glib and has nothing to do with gtk-2.6 ( gtk-1.2.x uses glib-1.2.x).

look in /usr/local/lib/pkgconfig and see if there is a file name glib-2.0.pc or type this in a console/xterm:

and post the output, then we will know if you have glib-2.x installed and where it is

Edit: make sure if glib-2.0.pc is in /usr/local/lib/pkgconfig to export that directory to your PKG_CONFIG_PATH before running the pkg-config command above:

EDIT#2:

when you use a prefix like "configure --prefix=/usr", /usr becomes the root of the installation. So for example, if you install gtk with a root of /usr, the libraries will be placed in /usr/lib, the executable (binary) files will go in /usr/bin, the header files will go in /usr/include, man pages in /usr/man, and so on.
