[Tinyos-help] Is it the tinydb "Cannot load fonts for IMF" error casues the tinydb cannot display result?

[泽 江]

Hello,everyone:
I have two quesitons:
1.Is it the tinydb "Cannot load fonts for IMF" error casues the tinydb cannot display result?
2.How can I make the DemoApp using the tossim instead of reading the serial port?
  I tried the tinydb in my fedora core4 using tossim.But I get the error of "Cannot load fonts for IMF".Although the tinydb 
still can run and appears the GUI but the query result could not displayed on the GUI.Is it the "Cannot load fonts for IMF" error 
casues the tinydb cannot display result?
  The packages I used are:
tinyos-1.1.0-1
tinyos-tools-1.2.1-3
task-tinydb-1.1.0-1
  ps:I have changed the gcc to 3.4.4 and nesc 1.2.4 also recompiled. toscheck returns no errors. The tinyviz can 
work normally.
  In addition, how can I use the DemoApp in the tinydb directory with tossim. How can I specify the program to 
read the tossim but not the serial port? I find it reads a config file:tinydb.conf, and have a line "comm-string:serial at COM1$57600
". Whether change that line have effect?
   
  1.What is the reason of "Cannot load fonts for IMF"? Is it this error causes the tinydb GUI could not display results?
