Hi, I tried to install Fiasco-L4Linux on Xscale-PXA255. I saw a "hello message" with fiasco kernel, sigma0, roottask, hello programs yesterday. When I start to compile L4linux, I got the following errors... ================================================================== /l4linux-2.6$ make CHK include/linux/version.h CC arch/l4/kernel/asm-offsets.s cc1: error: invalid option `abi=apcs-gnu' (1) cc1: error: bad value (armv4) for -march= switch (2) cc1: error: bad value (armv4) for -mcpu= switch make[1]: *** [arch/l4/kernel/asm-offsets.s] Error 1 make: *** [prepare0] Error 2 ==================================================================

...

Question 01:

Error (1): I solved by fixing the following code arch/l4/Makefile:77: CFLAGS_ABI :=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) $(call cc-option,-mno-thumb- interwork,) [change to] CFLAGS += $(call cc-option,-mapcs-32,$(call cc-option,-mabi=apcs-gnu),) $(call cc-option, -mno-thumb-interwork,) Error (1) is solved, but what is the difference between them?? (I just fix it, I don't know why...)

...

Question 02: Error (2): I read what "-march" option is on gcc manual, and found the permissible values for it are

armv2, armv2a, armv3, armv3m, armv4, armv4t, armv5, armv5t, armv5te, armv6, armv6j, iwmmxt, ep9312 In the file "arch/l4/Makefile:82 CFLAGS += -D__LINUX_ARM_ARCH__=4 -march=armv4" I just tried each values one by one for -march option, but all failed. How can I fix it and compile well??? Thank you!!
