D static lib called from C on Mac OS X

2012-04-25 Thread Nicolas Sicard 

Hi,

I am trying to use a D static library from C on Mac OSX Lion, but 
it always fails.


--- file mylib.d ---
module mylib;
import core.runtime;

extern(C) {
bool mylib_init() {
return Runtime.initialize();
}

bool mylib_free() {
return Runtime.terminate();
}
}
---

--- file main.c ---
extern void mylib_init();
extern void mylib_free();

int main() {
mylib_init();
mylib_free();
return 0;
}
---

I am compiling using:
$ dmd -c -lib mylib.d -oflibmylib.a
$ gcc -o main main.c -L. -lmylib -lphobos2

When I run ./main, I get a EXC_BAD_ACCESS (SIGSEGV) that seems 
related to thread local storage during runtime initialization.

Am I doing something wrong or trying to do something currently

More testing. This:

--- file mylib.d
module mylib;
import core.runtime;
import std.stdio;

extern(C) {
bool mylib_init() {
return Runtime.initialize();
}

bool mylib_free() {
return Runtime.terminate();
}

void mylib_hello() {
writeln(Hello from mylib);
}
}

void main() {} // Fake main
---

--- file main.c ---
extern int mylib_init();
extern int mylib_free();
extern void mylib_hello();

int main() {
mylib_init();
mylib_hello();
mylib_free();
return 0;
}
---

$ dmd -c mylib.d
$ gcc -o main main.c mylib.o -lphobos2 -lpthread -lrt
$ ./main

works on Linux (Unbuntu 11.10), but segfaults on OS X Lion.

Try changing void to bool there.

This was a typo in my first post. The problem is elsewhere.

Thanks
