Re: RE : Building kernel 2.6.21.3 for arm on cygwin

[Tom <fivemiletom@gmail.com>]

Hi Sam


enclosed is the 'k_smf.patch' which modifies three files to enable the 
kernel 2.6.21.3 to be built under cygwin:
host:  cygwin 1.5.24, hostcc= gcc 3.4.4
cross: arm-linux-uclibcgnueabi-gcc (GCC) 4.1.2
cmd:   make ARCH=arm CROSS_COMPILE=arm-linux- \
        HOST_LOADLIBES="-lcurses -lintl" at91rm9200dk_defconfig

I verified that this does not break building on a linux-host on this config:
host:  FC5, gcc 4.1.1-1
cross: arm-none-linux-gnueabi-gcc 4.1.1
cmd:   make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-


Let me know if I can help any further.
Tom
