[gobolinux-users] Rootless problem with Expect Recipe "Can't find Tcl configuration definition"

[Johannes Grosse]

Hi, 

I managed to Compile Expect. I may have missed something,
because the Expect recipe claims to depend on Tcl-Tk,
while on http://www.gobolinux.org/?page=recipes&name=tcl
I only find Tcl and Tk as separate packages.

Anyway, the recipe could be made to work by first
symlinking the tcl8.5a4 and tk8.5a4 directories in /Files/Compile/Source
to tcl8 and tk8 respectively. The reason is that the 
configure file searches for "../tcl[regex]" and [regex] will
not match "8.5a4".  (In other words you can simulate
my troubles my simply renaming the tcl and tk directories
in /F/C/S to something different.) 
The correct solution (as opposed to the symlinking hack
would be to hand over the correct path with the 
--with-tcl configure option.
I don't think that the correct path is in the Source
directory however. More likely something like
--with-tcl=/Programs/Tcl/Current/lib/,
though I haven't tried.

The next problem I ran into was that the Recipe violates the
FiboSandbox. This can be solved by replacing in the Recipe
the line
   '--exec-prefix=${prefix}'
by
   "--exec-prefix=${target}"

Now it compiles. 

Regards,
Johannes
