[GSOC] How to compile with sparc-rtems4.11-g++ command?

[panx at seas.upenn.edu]

Here is another one error message:

sparc-rtems4.11-g++  
-B/home/rtems/rtems-4.11-work/b-sis/sparc-rtems4.11/sis/lib/ -specs  
bsp_specs -qrtems   -g -Wall  -g    -mcpu=cypress     -c   -o  
o-optimize/runner.o runner.cc
Assembler messages:
Fatal error: can't create o-optimize/runner.o: No such file or directory
make: *** [o-optimize/runner.o] Error 1

In the makefile from example-v2, I modified the following part:
CSRCS = test.c
COBJS = $(CSRCS:%.c=${ARCH}/%.o)
to be like this:
CSRCS = runner.cpp
COBJS = $(CSRCS:%.cpp=${ARCH}/%.o)

Which part I was not doing correctly?

xiaochen
