Hello everyone,

I have a problem with the fromStringz function (std.string.fromStringz) when I try to compile with the GDC compiler (it works fine with DMD).

Here is a minimal code to see the error:


import std.stdio, std.string, std.c.stdlib;

int main () {
  char* s;
  s = cast(char*) malloc(2);
  s[0] = 'a';
  s[1] = '\0';
  writeln(fromStringz(s));
  return 0;
}


Compiling with DMD (works fine):
$ dmd testfsz.d

Compiling with GDC:
$ gdc testfsz.d -o testfsz
testfsz.d:8: error: undefined identifier fromStringz

It does the same thing on a friend's computer. I'm using GCC 4.9.1 on Kubuntu 14.10. Any idea where this comes from? Thanks in advance for your help!

fromStringz (in std.string) was introduced in D 2.066, gdc-4.9 was shipped when 2.065 was released.

Thanks! I will make my own version and use conditional compilation to import it or not in that case...

Looks like the function itself is very short:

inout(char)[] fromStringz(inout(char)* cString) @system pure {
    import core.stdc.string : strlen;
    return cString ? cString[0 .. strlen(cString)] : null;
}
