之前为了使用一个库，都是去下载源码，然后根据开发者提供的README手动用GCC编译，一直不能使用Makefile感觉很蛋痛，比如最近使用的ZThread
还是怪自己以前过于依赖IDE
最近发现用Cygwin就可以使用诸如./configure, make这样的命令，感觉灰常欣喜，尝试去编译ZThread库（因为我发现虽然之前我用GCC手动编译了ZThread但是在使用的过程中，ZThread总是往控制台上打印诸多的DEBUG信息，想必是编译选项的问题，我又不知道到哪个头文件中去找#define DEBUG，所以就想使用make，看使用ZThread作者写的configuration文件以及Makefile来编译能不能解决问题）
刚刚下载下来Cygwin就等着上去configure+make呢，问题就来了，输入./configure之后，等了一段时间报错（见红色文字）：

输入：libtoolize --copy --force提示libtoolize: command not found
咋办？搜了一下相关的问题，原来是因为安装Cygwin的时候没有安装libtool
重新运行Cygwin-setup（注意，无需卸载，重新运行setup，选择你没有安装的package即可），搜索libtool，勾选并安装，问题解决
然后再次运行libtoolize --copy --force，又报错：
$ libtoolize --copy --force libtoolize: putting auxiliary files in `.'. libtoolize: copying file `./ltmain.sh' libtoolize: You should add the contents of the following files to `aclocal.m4': libtoolize: `/usr/share/aclocal/libtool.m4' libtoolize: `/usr/share/aclocal/ltoptions.m4' libtoolize: `/usr/share/aclocal/ltversion.m4' libtoolize: `/usr/share/aclocal/ltsugar.m4' libtoolize: `/usr/share/aclocal/lt~obsolete.m4' libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
又搜了一下，在这篇BLOG说是因为没安装autoconf的原因，再回去安装autoconf，如图
再试一次libtoolize --copy --force
结果还是报同样的错误，回头去看（上面有图，就是libtool那张）原来是libtool-debuginfo和cygwin64-libtool没有安装
于是安装libtool-debuginfo和cygwin64-libtool
再试一次libtoolize --copy --force，成功运行
好了，继续：./configure --prefix D:/ZThread/bin #--prefix指定编译时输出二进制文件的目录
然后还是报错，又运行libtoolize --copy --force，还是报错，无语了
然后，上网搜了半天，在这里找到提示说使用：autoreconf --force --install --symlink
然后又报错Can't exec "aclocal"
继续搜，在这里找到提示说要安装automake（然后我就去Cygwin-setup安装了automake-1.8，注意不要重复安装多个版本，否则会出问题）
然后输入make install又提示make: command not found
还是同样的套路，把make package给勾选安装就行了
2——安装Java运行环境（JDK）)
