| |
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
