GDC on psptoolchain

[John Grindstaff]

Thanks for listing the compile flags. I successfully built an executable 
but there was no libgphobos.a appearing--which prevented me from 
instantiating any classes or structs in my test example (which operates 
similar to yours--an extern'd d function called from C).

Would it be possible to use a stripped down version of Tango or Phobos, 
perhaps something that has the base type/classinfo and memory management 
stuff and leave the rest alone? I just need auto memory management and 
classes and I can use all the sce* psp sdk functions for other things.

BTW, you might want to use pspDebugScreenPrintf and pspDebugScreenInit 
instead of printf for the C code. Last time I checked, they are very 
different and printf doesn't work.

(When I enabled D 2.0, the toolchain build stopped with compiler errors)

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?
