Dear @electricface, do you want research that problem and create PR?

electricface commented 5 years ago

no

Konstantin8105 commented 5 years ago

Thank you for clarification and issue. I will look later.

Konstantin8105 commented 5 years ago

add script for that C library, you can run ./scripts/vorbis.sh and look in folder ./testdata/vorbis

electricface commented 5 years ago

But there are still many errors and warnings

Konstantin8105 commented 5 years ago

Now, little bit less warnings:

Calculate warnings in file: testdata/vorbis/vorbis.go
        After transpiling : 4 warnings.
        Go build : 25 warnings
        Unsafe : 255

Please clarify - is it still important for you?

electricface commented 5 years ago

unimportant

Konstantin8105 commented 5 years ago

Now, that project is haven't some specific problem.

Calculate warnings in file: testdata/vorbis/vorbis.go
                After transpiling : 0 warnings.
                Go build : 3 warnings
                Unsafe   : 257

Thank for issue. Closed.
