hi all:
I follow below link and try to generate aarch32/64 user mode program.
http://permalink.gmane.org/gmane.comp.gcc.help/47571
But I get below error message:
aarch64-linux-gnu-gcc -mabi=ilp32 test.c
/media/sdb2/toolchain/arm/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux/bin/../lib/gcc/aarch64-linux-gnu/4.9.2/../../../../aarch64-linux-gnu/bin/ld:
skipping incompatible

when searching for -lgcc
Did I miss anything else to cross-compile aarch32/64?
appreciate your help in advance,
PS: below is my gcc information
# aarch64-linux-gnu-gcc -v
