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 Loading internal null logger. Install Log::Log4perl for logging messag +es CPAN: CPAN::SQLite loaded ok (v0.211) CPAN: LWP::UserAgent loaded ok (v6.26) CPAN: Time::HiRes loaded ok (v1.9742) Fetching with LWP: http://cpan.strawberryperl.com/authors/01mailrc.txt.gz CPAN: YAML::XS loaded ok (v0.65) Fetching with LWP: http://cpan.strawberryperl.com/modules/02packages.details.txt.gz Fetching with LWP: http://cpan.strawberryperl.com/modules/03modlist.data.gz Creating database file ... Done! D:\strawberryportable>perl test.pl Fragment shader: WARNING: 0:3: '' : #version directive missing
Then I download OpenGL::Shader from:

https://metacpan.org/pod/OpenGL::Shader

How can I solve the problem?

Thanks!
