GDC on psptoolchain

Wed Jul 23 04:39:31 PDT 2008

Hi, 
I was intrigued enough to have another go at compiling GDC for the PSP (my previous attempt half a year ago did not get me very far), and I can say that at least the toolchain builds fine (for D 1.0) with a working compiler and a libgphobos. (When I enabled D 2.0, the toolchain build stopped with compiler errors)

Here's what my psp-gdc -v produces:

Using built-in specs.
Target: psp
Configured with: ../configure --prefix=/pspdev --target=psp --enable-languages=c,d,c++ --with-newlib --enable-cxx-flags=-G0 --disable-libssp --enable-static --disable-shared
Thread model: single
gcc version 4.1.0 20060228 ( gdc 0.24, using dmd 1.030) (PSPDEV 20060507)

BTW you can also see the configure flags I used.

I wanted to see if I could get a working executable. So my test was, to have D function be called from a C main function (because the PSP sdk has some special initialization macros that I guess need to be defined to get a working executable). However when linking the program I got a lot of linker errors, originating from libphobos/std/math.d and libphobos/gcc/cbridge_math.c. My guess is that these come from the lack of double support on the psp toolchain. Could that be the case, or is it some kind of misconfiguration? Also is there some way of fixing this?

Thanks!

Here is the test program:
----------------------------------
testd.d:
import std.stdio;

extern(C) void dfunc()
{
        printf("Hello from D");
}

----------------------------------
#include <pspkernel.h>
#include <stdio.h>
PSP_MODULE_INFO("test", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER | THREAD_ATTR_VFPU);
extern void dfunc();
int main(int argc, char *argv[])
{
        printf("Hello World\n");
        dfunc();
        return 0;
}

----------------------------------
Here are the actual errors:
