Hi,
When I am building(Using newlib toolchain) the FreeRTOS applications which contain some printf calls in the code. It is giving the following linker errors. Stdio.h is also included in the application. Without printfs in the code, there are no errors.

Here are the linker options used in the make file

CCPATH = /home/avamsi/OpenRISC/binaries/openrisc
GCCVER = $(shell $(CC) --version | grep gcc | cut -d" " -f9)
LIBS = -L./drivers -ldrivers \
-L$(CCPATH)/lib/gcc/$(TARGET)/$(GCCVER) \
-L$(CCPATH)/$(TARGET)/lib \
-lgcc -lc -lm

Discarding any of these options giving linker dependencies. Do I have to provide any more libraries to make it work..

Thanks,
A.vamsi
