is unsafe for cross-compilation請問該怎麼解決？
我已經有在编辑/root/.bashrc 文件,在最后一行 export PATH=$PATH:/usr/local/arm/4.3.2/bin

通常“/usr/include”这样的路径是不能包含在交叉编译器的头文件搜索路径里的。检查你的交叉编译器设置。

我是依照光碟中的手冊安裝～測試編譯hello word~就出錯這樣的警告～
不過還是有編譯出執行檔～可以執行～指令arm-linux-gcc -v也是正常顯示版本～

kevin@kevin-T60:/opt/FriendlyARM/mini2440/examples/hello$ file hello
hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.14, not stripped



cat Makefile
CROSS=arm-linux-

all: hello

hello:
    $(CROSS)gcc -o hello hello.c

clean:
    @rm -vf hello *.o *~
