I made up a script from Fabian's "HOWTO MANUALLY INSTALL" to build
from the open source components etc.
When this had completed successfully, I simply tar/gzipped the /usr/NX
directory tree:
tar -czvf freenx-0.7.3.tar.gz /usr/NX
This was useful as I wanted to install FreeNX on a second server
running RHEL5.
My /usr/NX/lib directory looks like this:
libcrypto.so -> libcrypto.so.0.9.8
libcrypto.so.0.9.8
libjpeg.so -> libjpeg.so.62.0.0
libjpeg.so.62 -> libjpeg.so.62.0.0
libjpeg.so.62.0.0
libnxredir.so.0
libpng12.so -> libpng12.so.0
libpng12.so.0 -> libpng12.so.0.1.2.8
libpng12.so.0.1.2.8
libX11.so -> libX11.so.6.2
libX11.so.6 -> libX11.so.6.2
libX11.so.6.2
libXcompext.so -> libXcompext.so.3.2.0
libXcompext.so.3 -> libXcompext.so.3.2.0
libXcompext.so.3.2.0
libXcompshad.so -> libXcompshad.so.3.2.0
libXcompshad.so.3 -> libXcompshad.so.3.2.0
libXcompshad.so.3.2.0
libXcompsh.so -> libXcompsh.so.3.2.0
libXcompsh.so.3 -> libXcompsh.so.3.2.0
libXcompsh.so.3.2.0
libXcomp.so -> libXcomp.so.3.2.0
libXcomp.so.3 -> libXcomp.so.3.2.0
libXcomp.so.3.2.0
libXext.so -> libXext.so.6.4
libXext.so.6 -> libXext.so.6.4
libXext.so.6.4
libXrender.so -> libXrender.so.1.2.2
libXrender.so.1 -> libXrender.so.1.2.2
libXrender.so.1.2.2
libz.so -> libz.so.1.2.3
libz.so.1 -> libz.so.1.2.3
libz.so.1.2.3
If yours is the same I can't see why you're getting these error
messages.
Good luck
Chris
