gcc - cygwin64::./configure 返回 "configure: exit 77"

Question

我已经安装了 Cygwin64，现在我想安装 extundelete .

所以我下载了它，解压了文件，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

所以我打开 config.log 文件，我发现了一些错误:

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

.log 文件以 configure: exit 77

结尾

是否可以在 Cygwin64 中编译文件？

Answer 1

您的构建问题可能是由于从 C:\Users\franc 继承的权限导致构建过程所需的执行权限搞砸了。
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，由于其他原因，您不能在 Cygwin 上构建程序；见下文:

在适当的目录中，您将拥有:

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

为避免一些范围错误，您可以从 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 {} \;

然后构建

$ 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

而且您无法克服 Cygwin ext2 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，它无法挂载 Windows 无法识别的文件系统，因为它对 ext2 的支持非常有限，主要侧重于在外部磁盘上创建文件系统，但它不能真正使用它。
