Issue in installing in Ubuntu 12.04

[siddharthgoel88]

Post installation of the ibncurses-dev libopencv-dev libpulse-dev I was compiling the source code and I got the following error -

mkdir -p objs
gcc -Isrc/inc -O2 -Wall pkg-config --cflags opencv src/audio.c -c -o objs/audio.o

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

[cpd85]

@siddharthgoel88 can you try again?

[siddharthgoel88]

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

[mofarrell]

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

[siddharthgoel88]

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

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

what's wrong? My system is ubuntu14.04

[emgram769]

what version of portaudio are you running?

[zphj1987]

root@zphj1987-virtual-machine:~/p2p/p2pvc-master# dpkg --list|grep portaudio

[emgram769]

could you try installing 19?

[robincsamuel]

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)

[zphj1987]

i install portaudio19-dev it to be well

i do the

no error happen

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