cdylib: Clap not accepting arguments on Ubuntu (still works on Windows10) about bitconch-core HOT 5 CLOSED

need to investigate reason not working on ubuntu 18.04?

possible workaround:

• use urfave cli to parse the argument, then send the parameters to rust code

• use another cli parser to replace Clap.

• tweek the env and go build (possible different go compiler)

from bitconch-core.

possible workaround:

created a new branch fixissue85

1 - modify sources accept argument from go side.
2 - string passed to rust code like

#[no_mangle]
pub extern "C" fn hello(parm1: *const libc::c_char, parm2: *const libc::c_char) {
    let buf_parm1 = unsafe { CStr::from_ptr(parm1).to_bytes() };
    let str_parm1 = String::from_utf8(buf_parm1.to_vec()).unwrap();
    if !str_parm1.is_empty(){
      //pass the value from str_parm1}else{
      //pass the default value}
}

3 - modify c header file

void void hello(char *parm1, char *parm2);

4 - modfiy go file

func AGoFunction(parm1 string, parm2 string ){
cStr_1 := C.CString(parm1)
cStr_2 := C.CString(parm2)
C.hello(cStr_1,cStr_2)

}

from bitconch-core.

possible workaround

1 - replace gccgo/gc with llgo
building in progress...
2 - use gccgo

from bitconch-core.

as for commit adc878c,
this issue has been fixed: implementing urfave to accept arguments

from bitconch-core.
