Hi. I am building a project based on different libraries and at this point I am getting some unresolved externals that I can't find a way to fix them. I get this:

My toolchain is the last version, and I've been messing around with the Makefile for a long time but can't find a way to fix this. All the libraries compile without any complain. The makefile looks like this:

PSPSDK = $(shell psp-config --pspsdk-path)
TARGET = ZombieStation
OBJS = ZombieStation.o ZombieStationPSP.o Application.o ApplicationPSP.o ApplicationMode.o
LIBDIR = ./Core ./Display ./Game ./GUI ./Input ./Tests
INCDIR = $(LIBDIR)
LIBS = -lZombieTests -lZombieCore -lZombieGame -lZombieGUI -lZombieInput -lZombieDisplay -lpspgu

CFLAGS = -G0 -Wall -O2
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LDFLAGS =

include $(PSPSDK)/lib/build.mak

ifneq ($VS_PATH),)
CC = psp-g++
endif

I've used the search on the forums to see if anybody else had the same problem and all but still can't find a solution. Does anybody have any idea about what can I be doing wrong? Thanks in advance.
And congratulations for the excellent work on the sdk.

Just in case anybody has this problem in the future, I fixed it changing a makefile line to look like this:

LIBS = -lc -lZombieTests -lZombieCore -lZombieGame -lZombieGUI -lZombieInput -lZombieDisplay -lpspgu

I'm not very used to makefiles and it seems like the order of the libraries is very important.

Also I would like you to know that trying to fix this I deleted the whole /usr/local/pspdev directory, then downloaded the psptoolchain from svn on psp/trunk/psptoolchain and tried to install it but it resulted on an error while compiling a gdb project, reporting that the libintl.a was missing. I don't know if it's important or not since it's not an official release but I just wanted to warn you.

Thanks

Yeah, order is very important when using the gnu linker. People who come from other environments where this isn't the case get hit by it a bit before they figure it out.
