一般的：
configure:3866: $? = 0 configure:3855: gcc -V >&5 gcc: error: unrecognized command line option '-V' gcc: fatal error: no input files compilation terminated. configure:3866: $? = 1 configure:3855: gcc -qversion >&5 gcc: error: unrecognized command line option '-qversion'; did you mean '--version'? gcc: fatal error: no input files compilation terminated.
类似错误还有：
error: ac_nonexistent.h: No such file or directory,
出现这样的错误，不必理会。继续向下找。
