automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output

automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your

解决方法：
在bashrc中添加下面这一句：
export LC_ALL=C
然后source ~/.bashrc
就可以了
（生成configure啦~）
