I am not sure whether this is the correct place for this post. If not,
my apologies.
tcltklib is an extension to the Ruby code located in ext/tcltklib. It is
needed for tcl and tk programs to work with Ruby.
My problem is that there are problems which need to be overcome
to get it to build on linux systems, which seem not to be
documented.
In a nutshell, the Ruby build process from tar.gz distribution
attempts to compile it and sometimes does and sometimes doesn't.
It depends on whether or not the headers for tcl, tk and X11 are
available on the system and locatable. My experience is that if the
make process doesn't find all it needs it just leaves out tcltklib and
doesn't give an error message. In addition, when it finds tcl and tk
headers but not X11, the extconf.rb says that it cannot find tk.h,
which is there, and does not mention the X11 at all.
I had encountered this problem previously when installing Ruby
onto a version of Red Hat linux (9 I think) and solved that by
installing the X11 development files.
I have recently had a similar problem with SuSE Linux 9.2 (64 bit
version) which has a distribution of Ruby 1.8.1. which does not
contain a compiled tcltklib. I installed their (patched) Ruby sources
for the 64 bit edition, but still had trouble getting tcktklib to compile.
There is a dependence on the X11 headers, but also on something
else which I have not tracked down although I have been able to
compile it by hand. I have created
http://www.rubygarden.org/ruby?TclTkLib
where I have explained how I did this.
If there is documentation on tcltklib please let me know about it. If
not perhaps what I have said can help build something up.
Thanks
