[ECOS] Which default CFLAGS should a HAL define?

[Manuel Borchers <manuel at matronix dot de>]

Hi all,

when trying to build a network stack (OpenBSD) into my kernel, I
struggled over a missing define.

When building I got:
-- SNIP --
In file included

[The german error message means, that the file or dir couldn't be found)
After looking into the header file param.h I found out that these
includes were guarded by #ifndef __ECOS, which wasn't in my list of
global CFLAGS, but only in the build options for the BSD stack. I added
-D__ECOS in my ecc file and the build works now.

So, my question is, should this define (and which other defines, I'm
potentially missing?) be in the list of default CFLAGS defined by my
platform HAL?

Currently I'm defining just cpu-specific and optimization related
defines/options:

default_value { CYGBLD_GLOBAL_WARNFLAGS . CYGBLD_ARCH_CFLAGS .
                            "-mcpu=arm926ej-s -g -O0 -ffunction-sections -fdata-sections -fno-rtti -fno-exceptions " }

default_value { CYGBLD_ARCH_LDFLAGS . "-mcpu=arm926ej-s --no-target-default-spec -Wl,--gc-sections -Wl,-static -g -O0 -nostdlib" }


Cheers,
Manuel
