Re: Tcl_Init failed: can't read "env(TCL_LIBRARY)": no such variable

Hi, thanks.

- How did you build insight?
A: I built it by issuing configure;make; make install
- Where is it installed, i.e., --prefix?
A: I didn't add prefix argument. So it should be
/usr/local
- Are tcl/tk/itcl installed in --prefix?
A: I didn't install them seperately. I think they were
installed when I install insight
- What does "which tclsh8.4" return?
A:/usr/local/bin/tclsh8.4
- What does "which insight" return?
A: /usr/local/bin/insight
- Can you run it from your build directory?
A: you mean ./insight under the build directory? There
is no such file.

- TCL_LIBRARY is actually defined in and used by the
Tcl libraries. Can  you run just the tcl shell that
was installed by your insight installation?
A: when I run tcl, "tcl>" is able to appear.

BTW, the same problem exists for my installation of
insight 6.4.

Thanks again.
