Hi Ilija

I do not meet these warnings for LPC2XXX. I digged old post. It was
applied for hal_arm.cdl

http://ecos.sourceware.org/ml/ecos-patches/2007-10/msg00011.html

1) I get just 2 warnings when I build kernel/tests for LPC2XXX target

/tmp/t$ echo $ECOS_REPOSITORY 
/opt/ecos/ecos-3.0b1/packages

/tmp/t$ which arm-eabi-gcc
/opt/ecos/gnutools/arm-eabi/bin/arm-eabi-gcc

/tmp/t$ ecosconfig new olpch2294 kernel;ecosconfig tree&&make -s&&make -s tests
U CYGHWR_HAL_ARM_LPC2XXX, new inferred value LPC2294
headers finished
/opt/ecos/ecos-3.0b1/packages/hal/arm/lpc2xxx/var/v3_0b1/src/hal_diag.c: In function ‘cyg_hal_plf_serial_isr’:
/opt/ecos/ecos-3.0b1/packages/hal/arm/lpc2xxx/var/v3_0b1/src/hal_diag.c:260: warning: pointer targets in passing argument 1 of ‘cyg_hal_is_break’ differ in signedness
build finished
headers finished
build finished
/opt/ecos/ecos-3.0b1/packages/kernel/v3_0b1/tests/intr0.cxx: In function ‘void intr0_main()’:
/opt/ecos/ecos-3.0b1/packages/kernel/v3_0b1/tests/intr0.cxx:201: warning: the address of ‘void vsr0()’ will never be NULL


2) I have no warnings when I compile an application:

/tmp/t$ mkdir foo
/tmp/t$ cd foo
/tmp/t/foo$ echo 'void cyg_start(void){for(;;);}'>foo.c
/tmp/t/foo$ DST=foo SRCS=foo.c /opt/ecos/ecos-3.0b1/examples/build_Makefile ..
/tmp/t/foo$ make -s
/tmp/t/foo$

because a built Make.params contains the substitutions:

ACTUAL_CFLAGS := $(subst -frtti,,$(ACTUAL_CFLAGS))
ACTUAL_CFLAGS := $(subst -Woverloaded-virtual,,$(ACTUAL_CFLAGS))


Regards,

Sergei
