 Posted: Mon Sep 19, 2016 9:31 pm Post subject: R-Pi 2B undefined references in libGLESv2.so [SOLVED] |
 |
|
Hi, I'm having a recurring problem on my Raspberry-Pi 2B and cannot build librsvg. It seems to be caused by raspberrypi-userland, which is the parent package of the libGLESv2.so ... which keeps failing with message blocks like this:
| Code: |

There was a guy with a similar issue here: https://forums.gentoo.org/viewtopic-t-1041628-highlight-libglesv2.html but toggling gles2 USE flag doesn't do anything in my case.
Does anybody know what's wrong? Thanks!

| This is unfortunately a problem with mesa and raspberrypi-userland. Make sure that xorg-x11 is selected in eselect opengl. |

@chithanh thanks for the advice!
So it turns out that it was set to xorg-x11 when the raspberrypi-userland was still generating the errors ... maybe that's nothing but idk, is that any clue?
| Code: |
Available OpenGL implementations:
[1] raspberrypi-userland
[2] xorg-x11 *
|
I'll try eselecting [1] and see what happens ... |

Oh boy oh boy!! It builds! It needed to be point to raspberrypi-userland. Thanks again for the clue that fixed me up. |

I had the same problem when trying to build harfbuzz, while emerging world. This solution solves it. Thanks!
I wonder what that select command actually does, and why it solves the problem. Can anyone explain? |

I'm betting it tells the compiler to use either "/usr/include/GL.." or "/opt/vc/include/GL..". From what I can tell, there are a few differences not just in the code, but in the typedef's that are defined.

9a3eedi,
eselect opengl shuffles symlinks.
Many years ago, nvida-drivers used to need to do this to get things to build against opengl.
Its a feature.
The more you stray from the beaten path, the more of these features you encounter.
