I am working on Redhat distribution-7.0, in which i've upgraded binutils, gcc, glibc, module-init tools. The kernel I am using is 2.6.12.

As my system was using 2.2 kernel and i wanted to upgrade it to 2.6, i had to upgrade the above mentioned packages. Now, I want to upgrade the GUI interface as well, which is not working in 2.6.12.

As per your suggestions, I have downloaded the source files from x-org website. Now, after executing command
make world >world.log > 2>&1

I am getting the following errors in world.log:

I looked for expat.h and the file is there itself. So, why the file cannot be found? I am not changing the hosts.def file. Do i have to make any configuration changes there?

Hope to receive replies this time as well.

Thanks and Regards,
Nupur

I installed expat manually from the source
itself, by changing the mode of configure file in expat directory to
777 and then installed it. It was successful.

But it seems, something else is missing as well, as I am getting the
following errors:

Searched on google and someone said that install libfreetype6 on
slackware. Does it hold true for redhat as well. do i need to install
libfreetype6?

Probably that's what you need to do. Can't you upgrade to something more modern that comes with Xorg 6.8.2? Red Hat 7.0 is completely ancient so no wonder you're having trouble getting up to date software to compile on it.

That'd be like trying to upgrade a Win98 machine with the kernel and important system files from XP, its amazing you've got anything working. As a suggestion though, have you looked at the latest Centos (clone/fork of RHEL without needing to pay for updates) or Fedora distros? I can see no end of problems trying to retrofit something so ancient with something so new.

I have to upgrade the RedHat7 distribution only, as I have some settings there which I cannot afford to loose.

So, that is the issue. Rest all is working fine, all the services and all the other things are working perfectly fine, except for GUI interface. I need to get that working on RedHat 7 only.

This is called back to square one.

I installed freetype2 and fontconfig with zlib separately as i was getting errors related to them.

Now, I got the following error:

../../exports/lib/libXfont.so: undefined reference to `ssh_z_inflateEnd'
../../exports/lib/libXfont.so: undefined reference to `ssh_z_inflateInit2_'
../../exports/lib/libXfont.so: undefined reference to `ssh_z_inflate'
/usr/lib/libfreetype.so: undefined reference to `ssh_z_inflateReset'

This is the same error i got when i was trying to install XFree86. And because of the same error, I moved on to x.org. What would be the next step? I have already installed zlib from its source using the following commands:

1. ./configure --prefix=/
2. make test
3. make install
4. ldconfig

And it installed successfully.

Any suggestions?

woudln't it be --prefix=/usr? Check in /usr/include and see if there is a file zlib.h

Backup you /etc, /home and /var directories and reinstall with Centos 4.1 Seriously whatever you've got configured and setup it surely couldn't be more trouble to set it up again than go through all this.

Also RH7 already comes with a full set of packages for XFree86, KDE and GNOME - have you tried installing those?

Yes, there is a zlib.h in /usr/include and also there is libz.so in /usr/lib

Doing some more work on this, I found ssh_z_inflateEnd, sh_z_inflateInit2_, ssh_z_inflate , ssh_z_inflateReset in a header file ins/usr/local/include

That is added in my PATH as well, then also, why are they not getting recognized?

The PATH environment variable has got nothing to do with it. Its for directories containing executable files.

To specify exactly where include files are do there should be some options that allow you to specify paths to things
