Issue in installing in Ubuntu 12.04 about p2pvc HOT 16 CLOSED

what do you get when you run pkg-config --cflags opencv?

from p2pvc.

@siddharthgoel88 can you try again?

from p2pvc.

It still does not worked for me.
On typing pkg-config --cflags opencv I am getting following --
-I/usr/include/opencv

from p2pvc.

Can you check your opencv installation. It seems like the header for the library isn't where the compiler is looking for it.
/usr/include/opencv/cv.h

from p2pvc.

First point is that I do not have opencv installed but opencv2 got installed when I tried to install opencv through command line. Second that also does not have cv.h file. Look at the directory structure below -

on my machine there is a file /usr/include/opencv/cv.h

from p2pvc.

Same error here on ubuntu 14.04. I guess its something with opencv

what's wrong? My system is ubuntu14.04

from p2pvc.

what version of portaudio are you running?

from p2pvc.

root@zphj1987-virtual-machine:~/p2p/p2pvc-master# dpkg --list|grep portaudio
ii libportaudio-dev 18.1-7.1 amd64 Portable audio I/O - development files

could you try installing 19?

from p2pvc.

I just tried apt-get install, and from the installation message, I guess its 18.1-7.1
Setting up libportaudio0 (18.1-7.1) ...
Setting up libportaudio-dev (18.1-7.1)

i install portaudio19-dev it to be well

what is the output of pkg-config --libs opencv? specifically, does it include -lm?

i do the
export LDFLAGS="$LDFLAGS -lm" in the shell
no error happen

from p2pvc.

cool, thanks. I'll add it to the makefile

from p2pvc.
