I'm trying to get rolling with GDL and to help a friend to do the same. Both of us are using a MacBook running 10.9 Mavericks, with GDL 1:0.9.4-1 installed using fink (more conveniently with FinkCommander). Things are working fine on my machine, but on his we stumbled on a Dialog_Message() call, which failed in calling zenity. The zenity package is installed fine, and can be called from a Terminal window, even like this:
GDL> $zenity --help
The trouble is in running the command using Spawn, and it's not just zenity, even this simple test failed:
GDL> spawn,'ls',stdout & print,stdout
% SPAWN: Error managing child process.
I've looked this up and down to the limit of my Unix knowledge, and I can't see a reason why his system would fail at this while mine succeeds: we're both using "administrator" accounts, /tmp is writable on both, several other leads from Googling "SPAWN: Error managing child process" did not apply...
There is another detail that may well be connected to this issue. On my machine, FinkCommander reports this:
GNU Data Language
... but his (despite GDL working in every way except SPAWNing, as far as I can tell so far) reports:
We have used FinkCommander to Remove and Install his gdl package again, and end up with the same result. Any clues? Thanks for your time.
