current openVG installation guide is somehow broken:

[davenull]

the installation guide I was using is somehow broken:

Code: Select all

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


# Next, build the library and test:

git clone git://github.com/paeryn/openvg

cd openvg
#  make will compile the font utility program, create the default fonts,
#      compile the library's source files and create the shared libray:

make     #ok

make library #ok

make install  # ERRORS !!    
install -m 755 -p font2openvg /usr/bin
install: file "/usr/bin/font2openvg" can not be created no rights
Makefile:38 recipe for target 'install' failed
make: *** 8install] Error
make install

edit
resolved

sudo make install !!

paeryn, could you please update / rework the installation guide and cut it all down to the very essentials to be easily followable step by step ?

also compilation error for the example code:

no idea what happend, just made some completely different changes and settings to UART and i2c-0,
and suddenly I can execute the testopenvg program "in the terminal" (nevertheless, not just "execute", but anyway.)

Thank you, issue is resolved!
