Known problems
The list of known problems (on 23 May 2014) is:
- developers of Tcl/Tk found out in May 2011 that the Tk
raise command to raise a window may not work as expected in
some situations. As its behaviour depends on the operating system
graphics support and on the window manager there is no solution they
can offer. GPSMan uses this command to present pop-up windows, in
particular those asking for a confirmation or an answer and that
must be attended to by the user before execution goes on. This
means that when GPSMan seems to block and does not answer the user
should check whether there is such a window hidden below other ones
and waiting for some input.
- GPSMan blocks or gives strange error messages when trying to connect
to a Garmin receiver that has been turned off but still answers to a
product information request command.
- in Linux the Tcl/Tk error couldn't load file
"/usr/lib/gpsmanshp.so", cannot open shared object file usually
means that the
gpsmanshp library was not correctly installed.
- GPSMan support for Garmin receivers may need to convert between
bytes and floating point numbers. Tcl/Tk has no
machine-independent way to do
these conversions and GPSMan only implements them for little- or
big-endian architectures that follow the IEEE floating point
standard. Some Garmin receivers do not use protocols having
floating point numbers and are not affected by this.
