Opps - my two posts were meant for another thread! Sorry.

I deleted the raylib directory and sub directories and reinstalled raylib again - well tried to. Turns out that cmake is not part of the os and I had to install it. once I did, the installation went to completion. I compiled the examples successfully, but when I click on the binary to run it, I have...

update - turns out I had not installed cmake. Once that was done, raylib successfully installed. I ran make on the examples, but when I try to run them in a terminal window, a terminal window appears for a blink of an eye and goes away. Clicking on just Execute does nothing I can see. I am trying to...

I guess I should have listed the steps I have done so far: 1. git clone https://github.com/raysan5/raylib.git && cd raylib - done 2. mkdir build; cd build - done - created build in the raylib dir 3. cmake .. -DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc -DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++ \ -D...

I had been using openvg with Geany on my raspberry pi 3. Just got in my Raspberry Pi 4 and discovered I had to update the os from stretch to buster, then discovered that openvg is no longer supported. After doing a search, I found RayLib and it appears promising - however my limited experience is pr...

oh never mind. i put in the same thing you had suggested for the makefile for the installation and it works.

What do I need to put in my makefile for openvg. I am getting compile errors about not being able to find -iEGL and -lGLESv2
Thanks
David

Thanks so much for your quick and accurate reply. After making the suggested changes, openvg installed without a problem.
Kind regards,
David

I just reinstalled Jessie with Stretch on my Raspberry Pi. I had been using AJStarks openvg prior ( just Jessie) to reinstalling the os without problem. But now that I have installed the new OS. I started with sudo apt-get install libjpeg8-dev indent libfreetype6-dev ttf-dejavu-core followed by git ...

The framework is done, base covering in fiberglass is done - waiting on winter to end to finish. The driver’s display will be 3 Raspberry Pi 3, each with a 7” touch di...

Egads, it works! Turns out that the default color is 0,0,0- which was the color of the background, and increasing the width from zero also helped. Adding StrokeWidth(10), and Stroke(255,0,0) fixed my problem!
Happy Pi

I am working with a Raspberry Pi B+, trying to make an interactive display for a car I am building. I can draw text and rectangles with openVG, but several days of trying to draw polygons has ended with, uh, no polygons. Pointers are not my strong suit, so it is probably the problem. I have the usua...

Greetings - I am building a sports car form scratch and want to use my Pi as the main display for fuel, speed, rpm, etc. Another microprocessor will be collecting and formatting the data and passing it to the Pi via RS232. The Pi will display speed, rpm, fuel, etc. i am new to Java, but have been pr...
