Re: [ECOS] Problem with precompiled Cygwin arm-eabi toolchain

[smolugu <asksri at indiatimes dot com>]

Hi John,
I try to build in the configuration tool for STM32, I set the build path to
where I copied the arm-none-eabi tool chain i.e
C:\cygwin\ecos-3.0\arm_eabi_2009q3_63\arm-2009q3\bin.

actually its asking for arm-eabi-gcc but I couldn't find I got the package
for arm-none-eabi from
http://www.codesourcery.com/sgpp/lite/arm/portal/release1033.
I followed the steps to set tool
chaing->http://groups.google.com/group/python-on-a-chip/web/arm-toolchain-build?pli=1

after that when I build I get the following error.
.....
make[1]: Leaving directory `/ecos-3.0/temp/stm32_build/fs/fat/v3_0'
headers finished
make -r -C services/memalloc/common/v3_0 heapgeninc.tcl

Please can you let me know where its going wrong.

Thanks
