You have a compilation error. @foo should be Foo

However you should also get an error message not the assertion failure.

@SeanTAllen Hi, I was following the tutorial in this article: https://bluishcoder.co.nz/2015/12/16/c-linkable-libraries-with-pony.html

Without @ it will give Error: no C-API actors found in package 'foo'

[SeanTAllen]

Note what is in the article is actor@ Foo which isn't what is in your code

@SeanTAllen Oh, edited but that doesn't matter fow now. The result is still the same. :-P Is it only a problem on my side?

[SeanTAllen]

Home now. Just tried, I have the issue as well.

This is my bug, we shouldn't be emitting internal methods.

[SeanTAllen]

@iology the fix for this will in 0.14.0 that is going to be released this weekend

[jakwings]

Thanks. Successfully linked to the generated object file.

Fix for this has been released as part of 0.14.0
