cygwin installed , but make integration failed

[youngh070]

I have installed encfs under win10 cygwin64 on a lenovo X1 carbon laptop.
but make integration failed .
and after install , it works not ok .
can somebody help me out . thanks .

Details:
I fully obey the instruction : https://github.com/vgough/encfs/wiki/Windows
in section "Mainline EncFS with Cygwin"
the install runs ok except ./build.sh says "make integration failed "
the output log2 append at the end of this message .

Then I make install , it works ok .
but when I use it . the newly create file can not be accessed .
the following log1 , append here :

----------------- log1 start ----------

yh@yanghua-x1 ~
$ export LC_ALL=en_US.UTF-8

yh@yanghua-x1 ~
$ export LANG=en_US.UTF-8

$ encfs ~/.crypt4 ~/crypt4
The directory "/home/yh/.crypt4/" does not exist. Should it be created? (y,N) y
A drive is prefered for mouting, so a path like X: (or /cygdrive/x) should rather be used. Mounting anyway.
Creating new encrypted volume.
Please choose from one of the following options:
 enter "x" for expert configuration mode,
 enter "p" for pre-configured paranoia mode,
 anything else, or an empty line will select standard mode.
?>

Standard configuration selected.

Configuration finished.  The filesystem to be created has
the following properties:
Filesystem cipher: "ssl/aes", version 3:0:2
Filename encoding: "nameio/block32", version 4:0:2
Key Size: 192 bits
Block Size: 1024 bytes
Each file contains 8 byte header with unique IV data.
Filenames encoded using IV chaining mode.
File holes passed through to ciphertext.

Now you will need to enter a password for your filesystem.
You will need to remember this password, as there is absolutely
no recovery mechanism.  However, the password can be changed
later using encfsctl.

New Encfs Password:
Verify Encfs Password:

Yes, as stated in the Wiki and in #499, symlinks behavior depends on some Cygwin & WinFsp configuration items. If you need symlinks, you may experiment and set these settings upon your needs.
Other tests are fine.

$ encfs ~/.crypt4 ~/crypt4
The directory "/home/yh/.crypt4/" does not exist. Should it be created? (y,N) y
A drive is prefered for mouting, so a path like X: (or /cygdrive/x) should rather be used. Mounting anyway.

As stated, you should mount like this :
$ encfs ~/.crypt4 /cygdrive/x
or :
$ encfs ~/.crypt4 X:

Or from a Windows console :
$ encfs C:\enc X:

[youngh070]

thanks benrubson for your rapid reply .
"$ encfs ~/.crypt4 /cygdrive/x " and "$ encfs ~/.crypt4 X:"
that really worked .

I search wiki , but cannot find the usage mentioned above .
so , will you be so kind to update wiki page , in case other people do not know the mount syntax .
thanks again .

[benrubson]

Wiki modified 👍
https://github.com/vgough/encfs/wiki/Windows#usage

I'm closing this then, feel free to re-open if needed 👍

[youngh070]

excellent !

got updated wiki :
Note that you should provide EncFS with a drive-like mountpoint, such as X:
(or /cygdrive/x).

btw:
give a example such as "encfs ~/.crypt /cygdrive/x" seems more convenient .

[benrubson]

You're right, I just added 2 examples 👍

[youngh070]

👍

[youngh070]

I have write my install procedure , and make a guide in Chinese .
I can attach it here , if you feel it is usefull, feel free to link it to wiki .

在 cygwin 中安装 EncFs , 实现全目录树加密. (可用于 保存到网络云盘的方法)
参见: https://github.com/vgough/encfs/wiki/Windows

    注意, 我以下均以 64 bit 为准 , 如果您电脑是 32位, 请自行更换. 
    下载软件包, 如果不喜欢用 wget , 可以采用您喜欢的其它方式 . 

1: 下载 cygwin 安装包
wget http://www.cygwin.com/setup-x86_64.exe

2: 安装必要的开发包, 在 windows cmd 中, 执行安装命令:
setup-x86_64.exe -DL -q -a x86_64 -O -d -l d:\save\soft\cygwin --root c:\cygwin64 -s http://mirrors.163.com/cygwin -P "cmake,make,gcc-g++,gettext-devel,openssl-devel,procps-ng,perl-test-harness"
其中, (下面2个位置, 可换成你喜欢的位置):
d:\save\soft\cygwin 这是下载包存放在电脑的位置.
c:\cygwin64 这是cygwin 安装的位置

3: 安装 WinFsp , 请选择全安装, 下面2个都要选中安装 (Developer , FUSE for cygwin)
wget https://github.com/billziss-gh/winfsp/releases/download/v1.2POST1/winfsp-1.2.17346.msi

4: 在 cygwin 的 console 中, 安装 WinFsp 支持
cd /cygdrive/c/Program\ Files\ (x86)/WinFsp/opt/cygfuse/
$ sh install.sh
FUSE for Cygwin installed.

5: vi /usr/include/fuse/winfsp_fuse.h
原代码: return cygwin_create_path(
修改为: return (char *)cygwin_create_path(

6: 下载 encfs
wget https://github.com/vgough/encfs/releases/download/v1.9.5/encfs-1.9.5.tar.gz

7: 编译测试 encfs
tar -zxf encfs-1.9.5.tar.gz
cd encfs-1.9.5
./build.sh
make 时, integration 出错, 注意都是在 symlink, hardlink 错. 这个如果不使用连接, 可以忽略

8: 安装 encfs
make install (注意, 要在 cd build 目录中 再执行)

9: 试用
9.1 创建:
encfs /cygdrive/c/enc /cygdrive/x -- 加密盘保存在 c:\enc , 挂载在 X: 盘
-- 模式选择, 直接回车选项 standard
-- 设置初始密码.
9.2 文件操作:
echo aaa > /cygdrive/x/aaa.txt
ls -l /cygdrive/c/enc
-rw-r--r-- 1 aa None 1299 5月 3 15:03 .encfs6.xml -- 这是配置文件. 极重要, 千万保存好.
-rwx------ 1 aa None 17460 5月 4 02:55 5PBEBQX5JFVZXU6PHYULOJDHZBJ6D -- 这是 aaa.txt 的加密后版本.

ls -l /cygdrive/x
-rw-r--r-- 1 aa None 4 5月 3 15:04 aaa.txt -- 这是 aaa.txt 明文版本.
同时, 在windows 资源管理器中 就可看到多了一个 X: 盘. 里面有 aaa.txt

9.3 卸载:
encfs -u /cygdrive/x

10: 以上作完后, 可把加密后的文件夹, c:\enc 目录直接复制到 云盘. 如百度云 .
建议不要把 .encfs6.xml 复制到云盘. 但千万自己保存好, 因为这是全盘的密钥. 如果丢失. 全盘数据就全丢失了.

附:
第3步WinFsp 安装完. 有2个测试方法 :
1: 在windows explore 中, 映射一个远端 \memfs64\share , 到本地一个如 Z:
2: 在命令行中打.
memfs-x64 -u \memfs64\share2 -m *
会显示映射成如 Y:
这样, 新映射的内存磁盘可访问 .
