Hi,
I added the back-tick, thanks
I change priority to compile first main.cpp
g++ -std=c++11 -g 'pkg-config gtkmm-3.0 --cflags' 'pkg-config opencv --cflags' pkg-config --libs opencv' -std=c++11
problem is the same.
I tried
g++ -std=c++11 -g 'pkg-config gtkmm-3.0 --cflags' 'pkg-config opencv --cflags' pkg-config --libs opencv' -std=c++11
form the command line
end immediately
no cimpilation I think,
I check the presences of files by a "ls"
g++ -std=c++11 -g 'pkg-config gtkmm-3.0 --cflags' 'pkg-config opencv --cflags' pkg-config --libs opencv' -std=c++11
they are here
pi@raspberrypi:~/reretest $ ls
bin ihm.h ihm_sig.h obj pict.h reretest.layout
ihm.cpp ihm_sig.cpp main.cpp pict.cpp reretest.cbp
and meanwhile, BlueHazzard find a big beginner's mistake,
of course, about backticks
Thanks a lot, I can continue now, and be more careful
