BLT Patch (Re: Tcl Plugin?)

[Ken Cline]

Thanks Glen.

Update:

   I actually found the patch already on the mailing list
archives (you'd posted it on 11 Feb 97) and it worked great.
(Suggestion: Maybe the patch should be placed at the
needed-software site (in a BLT-README file perhaps), for
those who don't start searching the list archives at the
first sign of trouble. What'd ya think?)

   BTW, upgrading to 7.6/4.2 makes no difference to the
libtclobjc configure script, that is I get the exact same
error:
    Tcl_AppInit failed: version mismatch: library scripts
    expect Tcl version 7.5b1 or later but the loaded version
    is only 105

It appears that the libtclobjc configure script is hard
coded to search for either tcl7.5/tk4.1 or tcl7.4/tk4.0.

I decided to just ignore this problem and charge forward.
So far I've gotten heatbugs to work :) but not without some
problems with our X11R6/lib (e.g. "libXpm.so: could not read
symbols: Invalid operation", etc) ... we were able to fix
this temporarily but looks like the (acting) sys-admin and I
will have to take a closer at that directory.

Again, thanks for your help.

Ken.
