Unable to install OpenGL::Shader

SouthWind has asked for the wisdom of the Perl Monks concerning the following question:

I use 5.24 Strawberry Perl Portable Edition from http://strawberryperl.com/releases.html

I install OpenGL::Shader with cpan,it looks ok, but when I run test.pl, Perl say: #version directive missing.

D:\strawberryportable>cpan OpernGL::Shader

Then I download OpenGL::Shader from:

This is most likely because OpenGL shaders moved on a bit and now every shader program requires a `#version` directive at the start. You could add the appropriate line to the test shader, as discussed in this test report. A somewhat more recent version of OpenGL bindings is OpenGL::Modern, which also tries to be compatible to OpenGL and OpenGL::Shader, so maybe you want to try that if you want to do shader oriented programming.

I also seem to have a slightly older GLSL version. Does any of that account for the difference ? What version of Windows are you running ? What output does `perl -V` produce ?

I use Win10 Oh, yes - I see the same when I switch to Windows 10. Corion has already provided this link to the simplest solution. Cheers, Rob	[reply]
