then it is not working . it is given below .

$ /tools/H-i686-pc-cygwin/bin/i386-elf-gcc.exe  -o hello crt0.o hello.c -I
//d/ecos/work/tt2_install/include/
crt0.o(.text+0x0):crt0.c: multiple definition of `_mainCRTStartup'
crt0.o(.text+0x0):crt0.c: first defined here
crt0.o(.data+0x0):crt0.c: multiple definition of `___cygwin_crt0_bp'
crt0.o(.data+0x0):crt0.c: first defined here
/tools/H-i686-pc-cygwin/i386-elf/bin/ld: cannot find -lc

If you're trying to build an eCos app, you'd do well by following the
documentation. You're missing all sorts of compiler options. The Getting
Started Guide should help you.

[ECOS] Making of Cygmon for IXP1200

[gopi]

I got the cygmon tar kit for IXP1200 Eval board from netwinder.org

The configure & make involves making of so many things like gcc,
bison, yacc, gas etc.

We already have the armv4b-unknown-linux-** utilities from the
netwinder.org.   So, I want to use this gcc and other tools instead of
making them all over again just for cygmon.

Has anybody tried to do this?

thanx
gopi
PS: Is anybody working on redboot for ixp1200?
