openvg | Tools for exploring OpenVG

I have been following the blfs guide on KDE and I needed QT4 for one of the dependencies of "KDE-Baseapps". Running:

I write my pet project. At first, it was based on cmake and I set the path to qt libs from the console, e.g. cmake -DPATH_TO_QT:STRING=/home/user/Qt/5.11.1/gcc_64/ The variable PATH_TO_QT was declared as set(PATH_TO_QT "/path/to/your/Qt/" CACHE STRING "Path to Qt") With this configuration, my project worked very well.

However, I wanted to add in my project Conan Package Manager and I did it. My conanfile.txt:

I have makefile and I need to link two objects into "main" object

They are -> oglinet.o and libshape.o

their path in system -> home/pi/openvg/

Problem :I need to write full path and objects name(home/pi/openvg/libshapes.o) is possible to "make" them as Makefile variable for example home/pi/openvg/libshape.o into $(OBJ1) in makefile rule ?

Tried to make them as variable for example Obj1= /home/pi/openvg/oglinit.o if I compile that the compilator freeks out.

Working Makefile

I am trying to cross compile Raspberry pi3 B+; stretch software 2018-06-27 release, using Qt5.10.1, through Linux ubuntu 64bit according to this steps: https://wiki.qt.io/RaspberryPi2EGLFS

For sure I pay attention to this steps: https://bugreports.qt.io/browse/QTBUG-62216 and even try to edit make space also like this Error while cross compiling Qt for a raspberry pi3 on another time. I tried different arms pi/pi2/pi3/vc4, and even different Qt versions, although I was able to do it with Jessie, However with stretch I cannot get rid of this error;

I work on openvg library. Actually I worked for run this code with Code Blocks(on raspberry): https://github.com/raspberrypi/firmware/blob/master/opt/vc/src/hello_pi/hello_font/main.c

I achieved render color and I saw aliasing. But I want write text on screen with use same method. I analyzed this library: https://github.com/raspberrypi/firmware/blob/master/opt/vc/src/hello_pi/libs/vgfont/vgfont.h and tried use graphics_resource_render_text_ext() function but I took this message on a new terminal window:

assertion failure:font.c:176:gx_priv_render_text():inited aborted

My compile build message this:

Font.c's path: https://github.com/adafruit/rpi-firmware/blob/master/vc/sdk/opt/vc/src/hello_pi/libs/vgfont/font.c.

I went 176. line on font.c and tried call gx_font_init()(terminal window remark this line.) but I couldn't found this function anywhere(I tried find in raspberry's). If I cancel graphics_resource_render_text_ext() command, my code is good work. Why can't I use this function? My code this:

I am working on a sample code of Raspberry PI 3(file path is: /opt/vc/src/hello_pi/hello_tiger). I want to run this sample code on Code Blocks. I created new project on Code Blocks and added main.c file and header file. I compiled this code, and I got an error. This was the error:

'rotaten' undeclared(first use in this function).

If I run the code on LXTerminal using the ./hello_tiger.bin command it works fine. But I want to run this code on Code Blocks or any compiler(such as monodevelop). The main.c file is given below.

I tried with the example modules given from Qt. and I downloaded the qt-everywhere-opensource-src-5.9.3 tar file and extract it. then I run the following command.

./configure -v -prefix $PWD/qtbase -commercial -nomake tests -opengl es2 -egl

but I got these errors.

I've hit a wall compiling a fork of phantomjs, following these instructions. I've installed full Xcode from Appstore, and accepted the licence agreement (e.g. sudo xcodebuild -license) which seems to be the issue for other SO questions on this error. But when I try to compile:
