RE: itcl in insight

[Robert Bu <robert_bu at realsil dot com dot cn>]

Hi Patrick,

RHEL has no pre-built package for itcl.
I installed itcl3.4 by "configure; make all; make install". But tcl cannot find it.  I tried to modify tclConfig.sh to tell tcl the package path of itcl. It fails.
Finally, I added the package loading script to tk/pkgIndex as following. Then everything works fine. Thank you for your help.

# Robert: cannot tell tcl the path of itcl. So I add it here
if {![package vsatisfies [package present Tcl] 8.5]} {return}
package ifneeded Itcl 3.4 [list load [file join $dir .. itcl3.4 "libitcl3.4.so"] Itcl]

package ifneeded Itk 3.4 [list load [file join $dir .. itk3.4 "libitk3.4.so"] Itk]

package ifneeded Iwidgets 4.0.0 [list source [file join $dir .. iwidgets4.0.0 iwidgets.tcl]]

Best regards.
Robert Bu

Insight does not need itcl/itk development files at compile time anymore. Thus they are not checked. However you must have the runtime files installed at execution time.

The "3.3" is now only the lower version you need. Since Feb 16, insight is more tolerant about versions and package name spellings. If you have git-pulled it recently, it can only be a path problem, not under control of insight.

Try:
$ wish
% package require itcl
...     <-- here you have either an error or the itcl installed version.
% package require Itcl
...     <-- here you have either an error or the Itcl installed version.

If both fail, this is definitely a path problem in one of tcl or itcl RHEL package.
