Using BLT version 2.4i with TCL 8.3

[Katherine Bryce]

Hi,

The read-me for BLT version 2.4v through 2.4x say that they are compatible with TCL versions 8.0-8.3.

I'm wondering about version 2.4i, would it compatible with version 8.3? I realize that there would probably be some problems, and that downloading a newer version would be ideal, but can these run together?

I am trying to run BLT with ANSYS 6.0, and 2.4i is already on the network (HP Unix system). I have ANSYS finding the BLT install, but it doesn't like the version it's being asked for.

I get the error:

tcl generated the following stack trace:
version conflict for package "Tk": have 8.3, need 8.0
     while executing
"load /tools/tcl/blt2.4i/lib/libBLT24.sl BLT"
     ("package ifneeded" script)
     invoked from within
"package require BLT"

Any advice would be appreciated

thanks

The README may be a little misleading.  You can
compile BLT with any version of Tcl/Tk 8.0 - 8.3.
But once you build the BLT library (libBLT24.sl)
with a particular version of Tcl/Tk, it can only
be used with that version.  A libBLT24.sl built
with Tcl/Tk 8.3 can load into any tool (including
wish) built with 8.3 too.

So the error that you are seeing is that
libBLT24.sl was compiled with Tcl/Tk 8.0, but you
are loading it into a 8.3 interpreter.

The solution is to either build 2.4i with Tcl/Tk
8.3 or find an ANSYS built with 8.0. [And if
you are going to the trouble of rebuilding BLT,
you might as well build the latest version.  BLT
2.4y will be released hopefully this weekend.]
