This is what I do today (August 2010) on compiling the Linux kernel
tree targetting omap devices (BeagleBoard): First, my host server is a Ubuntu 9.04 32-bit, x86 machine. And then I downloaded the CodeSourcery ARM toolchain: http://www.codesourcery.com/sgpp/lite/arm/portal/subscripti...@template=lite And install it in the /opt/CodeSourcery directory. Then do a clone of the omap tree and subsequently issue the "make" thus: git clone http://www.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git cd linux-omap-2.6 export PATH=$PATH:/opt/CodeSourcery_G++_Lite/bin make ARCH=arm omap3_beagle_defconfig make ARCH=arm CROSS_COMPILE=arm-none-eabi- uImage And the partial compilation output: + make ARCH=arm omap3_beagle_defconfig warning: (USB_MUSB_HDRC_HCD && USB_SUPPORT && USB_MUSB_HDRC && (USB_MUSB_HOST || USB_MUSB_OTG) && USB_GADGET_MUSB_HDRC || USB_MUSB_OTG && <choice> && USB && USB_GADGET && PM && EXPERIMENTAL) selects USB_OTG which has unmet direct dependencies (USB_GADGET_OMAP && ARCH_OMAP_OTG && USB_OHCI_HCD) warning: (CPU_V7 && !ARCH_OMAP2 || CPU_MMP2 && ARCH_MMP) selects CPU_32v6K which has unmet direct dependencies (CPU_V6) warning: (CPU_V7 && !ARCH_OMAP2 || CPU_MMP2 && ARCH_MMP) selects CPU_32v6K which has unmet direct dependencies (CPU_V6) warning: (USB_MUSB_HDRC_HCD && USB_SUPPORT && USB_MUSB_HDRC && (USB_MUSB_HOST || USB_MUSB_OTG) && USB_GADGET_MUSB_HDRC || USB_MUSB_OTG && <choice> && USB && USB_GADGET && PM && EXPERIMENTAL) selects USB_OTG which has unmet direct dependencies (USB_GADGET_OMAP && ARCH_OMAP_OTG && USB_OHCI_HCD) # # configuration written to .config # + make ARCH=arm CROSS_COMPILE=arm-none-eabi- uImage scripts/kconfig/conf --silentoldconfig arch/arm/Kconfig warning: (USB_MUSB_HDRC_HCD && USB_SUPPORT && USB_MUSB_HDRC && (USB_MUSB_HOST || USB_MUSB_OTG) && USB_GADGET_MUSB_HDRC || USB_MUSB_OTG && <choice> && USB && USB_GADGET && PM && EXPERIMENTAL) selects USB_OTG which has unmet direct dependencies (USB_GADGET_OMAP && ARCH_OMAP_OTG && USB_OHCI_HCD) warning: (CPU_V7 && !ARCH_OMAP2 || CPU_MMP2 && ARCH_MMP) selects CPU_32v6K which has unmet direct dependencies (CPU_V6) warning: (USB_MUSB_HDRC_HCD && USB_SUPPORT && USB_MUSB_HDRC && (USB_MUSB_HOST || USB_MUSB_OTG) && USB_GADGET_MUSB_HDRC || USB_MUSB_OTG && <choice> && USB && USB_GADGET && PM && EXPERIMENTAL) selects USB_OTG which has unmet direct dependencies (USB_GADGET_OMAP && ARCH_OMAP_OTG && USB_OHCI_HCD) warning: (CPU_V7 && !ARCH_OMAP2 || CPU_MMP2 && ARCH_MMP) selects CPU_32v6K which has unmet direct dependencies (CPU_V6) CHK include/linux/version.h UPD include/linux/version.h CHK include/generated/utsrelease.h UPD include/generated/utsrelease.h Generating include/generated/mach-types.h CC kernel/bounds.s GEN include/generated/bounds.h CC arch/arm/kernel/asm-offsets.s GEN include/generated/asm-offsets.h CALL scripts/checksyscalls.sh <stdin>:1526: warning: #warning syscall fanotify_init not implemented <stdin>:1530: warning: #warning syscall fanotify_mark not implemented <stdin>:1534: warning: #warning syscall prlimit64 not implemented HOSTCC scripts/genksyms/genksyms.o SHIPPED scripts/genksyms/lex.c SHIPPED scripts/genksyms/parse.h SHIPPED scripts/genksyms/keywords.c HOSTCC scripts/genksyms/lex.o SHIPPED scripts/genksyms/parse.c HOSTCC scripts/genksyms/parse.o HOSTLD scripts/genksyms/genksyms CC scripts/mod/empty.o HOSTCC scripts/mod/mk_elfconfig MKELF scripts/mod/elfconfig.h HOSTCC scripts/mod/file2alias.o HOSTCC scripts/mod/modpost.o HOSTCC scripts/mod/sumversion.o HOSTLD scripts/mod/modpost HOSTCC scripts/kallsyms HOSTCC scripts/conmakehash CC init/main.o CHK include/generated/compile.h UPD include/generated/compile.h CC init/version.o CC init/do_mounts.o .... .... ....
