Hi Emanuel and Martin,
Thank you very much!
I have the code running now, I will try to make some processing and will
surely need more help.
The g++ command line I used is:
g++ -I/home/robotica/Sol/camaras/drivers/gige/aravis/src
-I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -O0 -g3
-Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o "main.o"
"../main.cpp"
and
g++ -L/usr/lib -L/home/robotica/Sol/camaras/drivers/gige/aravis/src
-L/usr/local/lib -o "test_gige" ./main.o -lglib-2.0 -laravis-0.4
Cheers!
Sol
