When using "CROSS_COMPILE=" compiler to compile, but using "CROSS_COMPILE=arm - none - Linux - gnueabi -" compile time appeared the following three questions:
Cc1 (1) : error: unrecognized command line option "- STD=gnu11";
(2) the cc1: warning: include the location "/usr/include/libxml2" is unsafe for cross - compilation; Cc1: warning: include the location "/usr/include" is unsafe for cross - compilation,
Have been trying to - STD=gnu11 instead - STD=gnu99 can be compiled, but an error
