I'm trying to install gnuplot 4.2.5 on centOS. I extract the tar.gz file, run the command ./configure and then run make. This is when i get the following errors on the screen towards the end:

/usr/bin/ld: skipping incompatible /usr/lib/libfontconfig.so when searching for -lfontconfig
/usr/bin/ld: cannot find -lfontconfig
collect2: ld returned 1 exit status
make[3]: *** [gnuplot] Error 1
make[3]: Leaving directory `/home/powder/software/gnuplot-4.2.5/src'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/home/powder/software/gnuplot-4.2.5/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/powder/software/gnuplot-4.2.5'
make: *** [all] Error 2

What can I do to fix this ??

# yum install gnuplot
or
# yum install gnuplot-emacs
... provides version 4.0.0

If you want the latest version :
http://sourceforge.net/projects/gnup...ar.gz/download
> > gnuplot-4.2.6.tar.gz
( The documentation for 4.2.5 says .. problems ..
.. use later version ..)

'gnuplot-4.2.6' : No errors on CentOS 5.x , x86. ( 32 bit )

What have you got ?? x86_64 ( 64 bit ) ? ?
.....
In fact, you have one error only :
" incompatible /usr/lib/libfontconfig.so "
.....

Yes. I have a x86_64. I shall try installing 4.2.6 and let you know if I get the same problem.

Thank you very much

I get the same error when installing gnuplot 4.2.6. Is it because I have a 64bit kernel?

No, the kernel is not involved when compiling this application.
Some 64-bit libraries are. Though, I don't see any arch issues in
the config files. May be in the source code ?
.....

And here ... another possible solution ...
( But still, is tested on 32 bit only.)
http://download.fedora.redhat.com/pu...1.fc12.src.rpm
> gnuplot-4.2.6-1.fc12.src.rpm = source code + a patch,
used to build " gnuplot-4.2.6-1el5.noarch.rpm " etc.
with the command : # rpmbuild -bb gnuplot-el5.spec
( The 'noarch' should be x86 ( or x86_64 ) : is a harmless bug.)
The edited spec file is attached as gnuplot-el5.spec.txt

Please install ( unpack ) gnuplot-4.2.6-1.fc12.src.rpm
to /usr/src/redhat/SOURCES/ , with the command
# rpm -Uvh gnuplot-4.2.6-1.fc12.src.rpm
May not work ... if so, please ...
1) cd /usr/src/redhat/SOURCES/
2) # rpm2cpio gnuplot-4.2.6-1.fc12.src.rpm | cpio -idmv

I got it fixed! My friend suggested the following:
yum install fontconfig fontconfig-devel

Then I tried installing and it worked.

Thanks for your help, anyways.
