为什么没有libgen.h文件？

[wjc870308]

我需要将一段C下的程序改到C++下，可是遇到了没有libgen.h文件的错误，请问该如何修改？谢谢

[silver9887]

libgen.h可能是苹果机下的库，windows的vc库不带这个文件

这个库是Gnulib里的，原来的程序应该是Linux/Mac下的吧。
要么你去http://www.gnu.org/s/gnulib/，看到那个Current Gnulib sources了么。
是Git维护的源码仓库，需要用个git客户端下载一份源码拿到VC++里去编译成lib。
要么你就去下一个Cygwin，在它里面用g++开发，肯定有Gnulib这个库，只不过这种方式不能生成纯正的Win32程序。
