version 4.0.1 re2rust default generate C code

[marryjianjian]

Thanks for amazing tool.
Well, re2rust should be worked as re2c --lang rust. But recently I upgraded my re2c to version 4.0.1(my system is Manjaro, PKGBUILD file may same as Arch). ALL re2rust/re2go/re2py/... just act like re2c, they all generate C code files.

version

my test

$ cat t.l 
fn lex(yyinput: &[u8]) -> bool {
    let mut yycursor = 0;
    /*!re2c
        re2c:YYCTYPE = u8;
        re2c:yyfill:enable = 0;

        [1-9][0-9]* { return true; }
        *           { return false; }
    */
}

fn main() {
    assert!(lex(b"1234\0"));
}

The problem is re2xx always generating C code, but re2xx --lang xx works fine.

Thanks for reporting!

I can confirm there is a problem, and it is scoped to the CMake build system. Syntax files are built into an object library in order to ensure they build early, and this object library does not get the same compile definitions as the main binary. I will fix it shortly and release 4.0.2 with the update.

Autotools build system works fine.

I'm glad it is helpful.:)

Fixed in re2c-4.0.2.
