Hi everyone!
I'm new to RTEMS, and having this question.
For short, how could I build application with DEBUG enabled?
What I have done:
1. Building RTEMS kernel with stm32f4 bsp with following options:
../rtems/configure --prefix=`pwd`/../../4.11.3 --target=arm-rtems4.11
--disable-networking --enable-rtemsbsp=stm32f4 --enable-tests
2. Preparing my own hello application:
mkdir myhello; cd myhello
cp $RTEMS_KERNEL_ROOT/rtems/testsuites/samples/hello/init.c hello.c
cp $RTEMS_BUILD_ROOT/share/rtems4.11/make/Templates/Makefile.leaf
Makefile
edit Makefile according to its README under Templates
3. Building myhello
export
RTEMS_MAKEFILE_PATH="/home/xxxx/yyyy/RTEMS/prjs/myhello/../../4.11.3/arm-rtems4.11/stm32f4"
make
Output:
> test -d o-optimize || mkdir o-optimize
> arm-rtems4.11-gcc --pipe
> -B/home/xxxx/yyyyy/RTEMS/kernel/stm32f4/../../4.11.3/arm-rtems4.11/stm32f4/lib/
> -specs bsp_specs -qrtems -Wall -O2 -g -march=armv7-m -mthumb
> -c -o o-optimize/hello.o hello.c
> arm-rtems4.11-gcc --pipe
> -B/home/xxxx/yyyyyy/RTEMS/kernel/stm32f4/../../4.11.3/arm-rtems4.11/stm32f4/lib/
> -specs bsp_specs -qrtems -Wall -O2 -g -march=armv7-m -mthumb
> -march=armv7-m -mthumb -o o-optimize/hello.exe o-optimize/hello.o
>
> arm-rtems4.11-nm -g -n o-optimize/hello.exe > o-optimize/hello.num
> arm-rtems4.11-size o-optimize/hello.exe
> text data bss dec hex filename
> 69572 1660 129416 200648 30fc8 o-optimize/hello.exe
> cp o-optimize/hello.exe o-optimize/hello.ralf

however if I build with debug it failed:
> make clean; make debug
> make -f Makefile MAKEFILE=Makefile VARIANT=DEBUG

I try to rebuild BSP with --enable-rtems-debug flag, it also didn't
generate *_g.a files.
So how could I build BSP with debug enabled?
