this includes the main script, some of the GUIs, the Python module,
the Tcl package, some image fies.
On a sim system, axis, tkemc, xemc all start. runtests pass.
a system with realtime wasn't yet tested.
packaging probably requires additional changes and was not yet tested.
Locate emc.so, hal.so, emc.tcl and a new pkgIndex.tcl file in a directory that
is a subdir of a directory included in the tcl auto_path list as configured for
the tcl/tk packages in the ubuntu distribution.
For a conventional build with --prefix=/usr, the chosen parent dir is:
/usr/lib/tcltk
and the shared library files will be located in the subdir:
/usr/lib/tcltk/emc2
With these changes, aan external tcl program should be able to say:
package require Emc 1.0
and/or
package require Hal 1.0
For this normal case, no extra configuration is required.
For an installed emc built with --prefix=/otherlocation, the using
application must modify the tcl auto_path list:
e.g., lappend auto_path /otherlocation/lib/tcltk
or set the TCLLIBPATH appropriately
e.g., export TCLLIBPATH=/otherlocation/lib/tcltk
For a run-in-place build of emc, '. scripts/emc-environment' to set
TCLLIBPATH appropriately.
with an error, show these and 'dmesg' information in a GUI window if we
ran without a tty; otherwise, copy the temporary files to the home directory
and print a message saying where to look.
