cmake cygwin 64：：./configure返回“配置：出口77”

我已经安装了Cygwin64，现在想安装extundelete。
所以我下载了它，解压缩了文件，但是当我运行./configure时，它说：

$ ./configure
Configuring extundelete 0.2.4
configure: error: in `/cygdrive/c/Users/franc/Desktop/extundelete-0.2.4':
configure: error: C++ compiler cannot create executables
See `config.log' for more details

因此，我打开config.log文件，发现了一些错误：

configure:2876: $? = 0
configure:2865: CC -v >&5

并且.log文件以configure: exit 77结尾
是否可以在Cygwin64中编译文件？

您的生成问题可能是由于从C:\Users\franc继承的权限导致生成过程需要执行权限。
使用/home/franc或/usr/src目录或其他类似目录。

不要在Windows主目录下构建。

不幸的是，由于另一个原因，你不能在Cygwin上构建程序;请参阅以下内容：
在适当的目录中，您将拥有：

$ ./configure
Configuring extundelete 0.2.4
Writing generated files to disk

要避免某些范围错误，可以从makefile中删除限制调用

$ find . -name Makefile -exec sed -e "s/-std=c99//" -i {} \;
$ find . -name Makefile -exec sed -e "s/-std=c++0x -std=c++11//" -i {} \;

然后构筑了

$ make
make -s all-recursive
Making all in src
...
insertionops.cc: In function ‘std::ostream& operator<<(std::ostream&, const ext2_inode&)’:
insertionops.cc:36:36: error: ‘const struct ext2_inode’ has no member named ‘i_dir_acl’; did you mean ‘i_file_acl’?
   36 |   os << "Directory ACL: " << inode.i_dir_acl << std::endl;
      |                                    ^~~~~~~~~
      |                                    i_file_acl
make[2]: *** [Makefile:437: extundelete-insertionops.o] Error 1
make[1]: *** [Makefile:268: all-recursive] Error 1
make: *** [Makefile:208: all] Error 2

并且无法克服Cygwinext 2 inode结构缺少扩展属性的问题。
由于Cygwin是一个Windows用户模式程序，它不能挂载Windows不识别的文件系统，因为它对ext 2的支持非常有限，主要集中在外部磁盘上制作文件系统，但它不能真正使用它。
