Windows Mobile 2003 is Microsoft's re-branding of their PocketPC Windows/CE based operating system for the post PocketPC 2002 version.
MNO I haven't yet been able to get Tcl/Tk to run correctly on this platform with celib [L1 ]- some things work, but sockets in particular seem to be broken.
Sockets code triggers an error which leads to a dialog box with "tcl: select: 10022" in it, both when using the Rainer Keuchel Tcl 8.4a2 and the 8.4.6 port by Jeffrey Hobbs.
Other code (e.g. iFile) seems to work
I suspect, however, this sockets error may be a problem in celib under WM2003, rather than in Tcl/Tk itself. My preliminary attempts to compile celib specifically for WM2003 using MS eVC++ 4 have failed miserably, but this could just be that my eVC environment is not set up correctly yet.
