Use of glPushMatrix() and glPopMatrix() doesn't work.

Use of glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE) works fine.
Paeryn, thanks very much!

Paeryn, thanks for advice.
It had partly helped me.
Now i have this image. It's yellow and partly transparent.

P.S. I use memset in draw_xxx functions to free memory.
I'm doing that because there is no automatic garbage collector.

How can i work with textures without glEnable? Here is part of my code. If it will be necessary i will show entire code but it's big. It's based on hello_triangle example and draws one line and texture. Textures and primitives are driven in function redraw_scene. Printscreens of work are in applied ...

Good afternoon. My task is to create application which draws one panel. This panel consist of primitives(triangles, rectangles, circles) and labels (textures). For this task I'm using Open GL ES 2.0 and language C (gcc compiler). Now I can draw primitives and textures separately. When I'm trying to ...

Guys, i'm grateful to you!
All is working!

At the beginning i checked file sources.list: there was just one link on the Raspbian's official site.
After that I used command apt-get, as you have advised and all errors disappeared!
System is working correctly!

Thank you!

rpdom, fruitoftheloom thanks for advices.
I'll try to apply them.
I was installing libudev because before it i tried to install libusb. And libusb asked me to install libudev.
What is AFAIAA?

P.S. rpdom, when you was speaking about Raspbian site, did you mean this one: http://raspbian.com?

Operation system is Raspbian.
Library was downloaded from this site: https://packages.debian.org/wheezy/armh ... 0/download
I suggested that it will be run on Raspbian because Raspbian is a version of Debian.

Good evening! I have trouble with booting X Window System after I was trying to install libudev. Libudev was installed with help of command dpkg: dpkg –install libudev0_175-7.2_armhf.deb. This command wrote that it’s unpackaged libudev and that was all. I decided to reboot system. During rebooting I...

Good morning. I have Raspberry Pi, model A and OS Raspbian on it. Yesterday I was working on it for 4 hours. After installing of new library (libudev) I decided to reboot it. First problem I met was that I couldn't open shut down menu for rebooting. For rebooting device I used command "shut down -r ...

Good morning. I have Raspberry Pi, model A and software (OS Raspbian) for it. I'm going to buy model B. Can I use software from model A on model B? Or there are differences and I need to change something? I know that main difference between these models is that model B has RAM 512 MB. Is there somet...

Good evening. Maybe my question is very frequent, but i couldn't find complete answer on it. What language can you advise for work with Open GL ES? C++ or C? Are they equal for this graphic library? The reason for this question is that I found a big count of examples of working with this library on ...
