I'm looking for what I'd hope is a fairly simple sample Qt program
that reads the analogs and digitals on the TS-7KV board (or on another
board in the family, like the TS-7250 processor, etc.) Based on all
of the Qt/E discussion here over the past few years, someone must've
written something like this. Since I'm switching to Qt (and C++) from
Windows (and C) or linux text and ncurses (also C), I' hoping that a
small example that at least slightly matches what I'm going to be
doing is the best thing for me to get started. Does anyone know where
I can find such a thing?
For anyone interested in my current situation (hint: tips and
suggestions welcome), I'm currently struggling with getting the
Qt/Embedded development stuff built/installed on a USB drive built
using the debian-sarge-1.12.tar file (all files are from
ftp.embeddedarm.com) for my TS-7250/TS-7KV. I mounted the USB using
sh loadUSBModules.sh
sh loadUSB.sh
Then I un-tar'ed qt-embedded-free-3.3.4-compiled-full.tar.gz to the
root of the USB, only to discover that it is a RUNTIME, NOT a build
environment as I'd expected. So, I grabbed
qt-embedded-free-3.3.4-src.tar.gz and extracted it to /usr/local and
tried running ./configure. Unfortunately, the debian image is missing
g++ so configure failed. Luckily, what was really missing was a link
from g++ to g++-3.3 and when I added that, configure ran (only
complaining about missing the cmp utility, which apt-get didn't know
about, either, but is in every other linux system I have). The
configure command took just over an hour to finish. I'm now running
make. Hopefully power will stay up for the next few days...
Hmmm... a less than encouraging message just came up on the compile
screen:
kernel/qgfxraster_qws.cpp:1415: warning: comparison is always false
due to limited range of data type
I wonder what Qt/E component code won't quite work right...
