Hi @yml that is a really good example to play with (I will definitely keep this in mind in the future), but unfortunately c2go does not have enough features to be able to process that codebase... at least not yet!
The AST (the structure that describes the C code) is ingested from the clang output. There are still particular lines, like this one from the error message...
FieldDecl 0x21391d8 <line:75:2, col:15> col:2 'unsigned int'
...that it cannot yet understand. Here are the test cases for FieldDecl. Once a new test case is added, and this regex is updated it should be able to understand this input.
Like I said, we are still far away from being able to compile kilo.c, but one step at a time...
from c2go.

I believe this is fixed with #31
from c2go.

Thanks for the update @yml. There is still a lot of work to get kilo.c working, but we definitely are making progress 👍

// Warning (UnaryOperator): :0 : Cannot transpile UnaryOperator: err = Cannot transpileToExpr. err = Cannot transpile ParenExpr. err = Cannot casting {int -> }. err = Cannot resolve type '' : probably an incorrect type translation 1

// Warning (UnaryOperator): :0 : Cannot transpile UnaryOperator: err = Cannot transpileToExpr. err = Cannot transpile ParenExpr. err = Cannot casting {int -> }. err = Cannot resolve type '' : probably an incorrect type translation 1
So, now problem of kilo is unsupported C libraries.
