C/C++ clashes using lastest PSP toolchain

[TommyBear]

Hi Guys,

I'm getting this:

Code: Select all

actor.o:(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'

trying to compile a .cpp file. Now my compiler flags are:

$(CC) $(OBJS) -lm -lc -nostartfiles -o out

__gxx_personality_v0 is implemented in libstdc++, but if I include that using

$(CC) $(OBJS) -lm -lc -lstdc++ -nostartfiles -o out

I get:

Code: Select all

Malloc and friends are implemented in libc, so what gives..... anyone? :(

They are implemented in libc for specific architectures. Afaik the libc malloc does not work on the PSP, you will either have to write your own or wait for the PSP SDK to be released if you don't want to do that.

Yep that's ok someone has already written these which is nice! :) Thanks everyone.
