Hi all,
after changing all Gmakefiles I have seen that
GRASS doesn't start any more 
ERROR: program 'g.gisenv' cannot be executed because:
Neither a command line (cmd) or interactive (inter) version was found
in any of the main, alpha, or contrib directories.
This should be simple to fix as the
src/front.end/main.c
needs to be updated to reflect the removed main, alpha, or contrib
directories (real_path variable). However, I can't manage this...
Sorry, expert wanted. generally it should be simple to fix (I got
lost with all the pointers and lists there).
Before fixing this problem. Should we consider maybe eliminating it?
The only programs it really serves a purpose for are shell scripts and
compiled programs that have not yet implemented a G_parser() interface.
I would suggest we consider just putting the executables in grass5/bin
directly and try to avoid some of these convoluted pathways (and weak
links) to the programs. Undoubtedly I haven't considered something.
But I wanted to make the suggestion anyway.
The README says:
----------------------------------------------------
This program is to decide if it should run
etc/interactive programs or etc/command programs.
It should live in etc/front.end and be linked to
names in bin that have programs/shell scripts in
etc/interactive and etc/command of the same name:
ln etc/front.end bin/window
for etc/command/window and etc/interactive/window
When user runs window, this executes etc/front.end
but argv[0] will have the name "window", which
front.end will use to build the two program names
etc/interactive/window and etc/command/window.
---------------------------------------------------
But, generally we have been eliminating this distinction between
interactive and command scripts. It's easy enough for an interactive
only program to do something like:
--------------------------------------
if (argc > 1)
{
G_fatal_error ("This program must be run interactively.");
}
--------------------------------------
or probably better (even though it's more code...)
--------------------------------------
struct GModule *mod;
G_gisinit(argv[0]);
mod = G_define_module();
mod->description = "pgm -- do xyz interactive thing." ;
/* No options */
if(!G_parser())
exit(-1);
if (!isatty())
G_fatal_error ("This program must be run interactively!");
