1. sudo apt-get install libjpeg8-dev indent libfreetype6-dev ttf-dejavu-core

2. git clone git://github.com/ajstarks/openvg

3. openvg 설치하기

pi@raspberrypi ~ $ cd openvg
pi@raspberrypi ~/openvg $ make
pi@raspberrypi ~/openvg $ make library
pi@raspberrypi ~/openvg $ sudo make install

4. example 빌드하기

pi@raspberrypi ~/openvg $ cd client

pi@raspberrypi:~/openvg/client$ make all

gcc -Wall -I/opt/vc/include -I/opt/vc/include/interface/vmcs_host/linux -I/opt/vc/include/interface/vcos/pthreads -I..  -o shapedemo shapedemo.c ../libshapes.o ../oglinit.o -L/opt/vc/lib -lEGL -lGLESv2 -lbcm_host -lpthread  -ljpeg
/usr/bin/ld: cannot find -lEGL
/usr/bin/ld: cannot find -lGLESv2
collect2: error: ld returned 1 exit status
Makefile:7: recipe for target 'shapedemo' failed
make: *** [shapedemo] Error 1
pi@raspberrypi:~/openvg/client$

5. Makefile 수정

아래 링크를 통해 확인해 보면 Makefile 버그가 있다고 하네요

따라서 버그를 수정하고 빌드하면 됩니다.
