Meshalyzer does not compile: Frame.cc: ‘glDeleteRenderbuffersEXT’ was not declared in this scope

[Batazai]

Hello, Following the instructions on https://carpentry.medunigraz.at/carputils/getting-started/visualization-tools.html#meshalyzer to install meshalyzer I get the following error:

baltasar@computer: make
[...]
Frame.cc: In member function ‘void Frame::delete_objs()’:
Frame.cc:33:3: error: ‘glDeleteRenderbuffersEXT’ was not declared in this scope
   glDeleteRenderbuffersEXT(1, &_color_rb);
   ^~~~~~~~~~~~~~~~~~~~~~~~
Frame.cc:33:3: note: suggested alternative: ‘glDeleteTextures’
   glDeleteRenderbuffersEXT(1, &_color_rb);

[... and similar for glDeleteRenderbuffersEXT,  glGenFramebuffersEXT, 
glBindFramebufferEXT, glGenRenderbuffersEXT, glBindRenderbufferEXT, 
glRenderbufferStorageEXT, glFramebufferRenderbufferEXT,
glCheckFramebufferStatusEXT, glBindFramebufferEXT ...]

make: *** [<builtin>: Frame.o] Error 1

The log from the make command is appended. Because of the colour code inside it can be best displayed by cat meshalyzer_not_install_log.txt.

If there is anything else you need, I'll be happy to provide the information. Thank you in advance

Hi Do you have a recent version of GL? I have heard that GLee no longer works and I need to switch to GLEW. My colleague downgraded the version of his library.

I am planning to upgrade to GLEW when I get some free time.

Cheers Ed

Hi, Thanks for the fast response!

I have GL version 4.6.0.. It is the newest but from 2017. Can you recommend another version? I found mine using visualinfo of the glew-utils package using visualinfo | grep "OpenGL version".

I tried to changed it to glew myself but I didn't manage to do so. If you could take a look into it it would be great. Thanks

I had the exact same issue on a Fedora 29 machine.

According to glxinfo the GL version is the same as yours - see below: OpenGL version string: 4.6.0 NVIDIA 418.43 OpenGL shading language version string: 4.60 NVIDIA

To fix the issue, I had to downgrade mesa-libGL-18.3.4-1 to mesa-libGL-18.2.2-1. A couple of other packages were following to preserve consistency.

Cheers, Toni
