For me to get Devkitadvance working I had to link with

crtbegin.o
crtend.o
libstdc++.a

and don't use -nostdlib OR -nodefaultlibs otherwise you'll have to link
with libg.a and libgcc.a.


Cheers
Aaron

Hi everybody!
I would to user OOP on GBA. Is it possible ?
My test application (compiled under GCC - DevKit Advanced based on GCC3.0.1
if I don't mistake) need to alocate some memory using new [] operator and
free it using delete []. Linker throws errors:

C:\GBA\prj\dyna>gcc -o
dyna.elf -mcpu=arm7tdmi -I..\agblib\include -L..\agblib\l
ib main.cpp

/cygdrive/c/WINDOWS/TEMP/ccfWu9Mh.o: In function `Console::Console(unsigned
shor
t, unsigned short)':

`operat
or new[](unsigned long)'

/cygdrive/c/WINDOWS/TEMP/ccfWu9Mh.o(.text+0xe28): undefined reference to
`__gxx_
personality_sj0'

I understand new and delete work on dynamically alocated memory. I don't
know this kind of memory is allowed on GBA.

I call my tet class Console - it is included by "main.cpp".
I am working on Win98.

What can I resolve this trouble ?

Best regards

Jerzy Kut
