Question

我目前正在尝试在Windows 10上构建exe / binary文件以支持 ffmpegthumbnailer 。我阅读了许多有关使其运行的文章，但似乎没有一个能满足我的需求。我目前在 C：\ ffmpegthumbnailer-2.2.0 中存储了ffmpegthumbnailer-2.2.0。我看到一个名为 CMakeFiles ， dist ， kffmpegthumbnailer ， libffmpegthumbnailer ，人，测试和声音文件。在目录中运行make时，会收到

User@User-WIN10 /cygdrive/c/ffmpegthumbnailer-2.2.0/man
$ make
make: *** No targets specified and no makefile found.  Stop.

如何构建/制作exec文件，以便可以使用PATH变量查找ffmpegthumbnailer？

更新1：我尝试了 automake 命令，但收到了以下消息

$ automake
/cygdrive/c/RubyDevKit/mingw/bin/automake: /cygdrive/c/RubyDevKit/mingw/bin/automake-1.11: /bin/perl: bad interpreter: No such file or directory
/cygdrive/c/RubyDevKit/mingw/bin/automake: line 156: /cygdrive/c/RubyDevKit/mingw/bin/automake-1.11: No error

更新2：

我跑了cmake，收到了下面的消息。

CMake Warning at /usr/share/cmake-3.6.2/Modules/Platform/CYGWIN.cmake:15 (message):
  CMake no longer defines WIN32 on Cygwin!

  (1) If you are just trying to build this project, ignore this warning or
  quiet it by setting CMAKE_LEGACY_CYGWIN_WIN32=0 in your environment or in
  the CMake cache.  If later configuration or build errors occur then this
  project may have been written under the assumption that Cygwin is WIN32.
  In that case, set CMAKE_LEGACY_CYGWIN_WIN32=1 instead.

  (2) If you are developing this project, add the line

    set(CMAKE_LEGACY_CYGWIN_WIN32 0) # Remove when CMake >= 2.8.4 is required

  at the top of your top-level CMakeLists.txt file or set the minimum
  required version of CMake to 2.8.4 or higher.  Then teach your project to
  build on Cygwin without WIN32.

Answer 1

如评论中所述，当软件包坚持构建文档时，即使缺少工具，要避免构建失败也很棘手。我经常遇到Autotools的问题，但我不记得在Cmake上遇到过此问题。我不是一个想像力强的CMake专家，所以请细细阅读下面的信息。

这可能对您有用。如果这是一个Autotools项目，我会做等效的事情：

$ git clone https://github.com/dirkvdb/ffmpegthumbnailer.git
$ cd ffmpegthumbnailer

$ rm -rf man/
$ sed -i '\|/man/|d' CMakeLists.txt

$ mkdir ffmpegthumbnailer_build
$ cd ffmpegthumbnailer_build/

$ cmake ../

上面的sed是一个简单的match and delete line。它删除引用文档的配方。 sed使用|条作为分隔符，因为它与/man/相匹配（更改避免了牙签倾斜）。

$ git diff
diff --git a/CMakeLists.txt b/CMakeLists.txt
index e708812..af3d8c2 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt

 if (ENABLE_THUMBNAILER)

我有一些缺少的软件包，所以我无法对其进行进一步的测试：

  CMakeLists.txt:47 (find_package)

还要注意，有一个--disable-manpages自动工具选项。问题是，没有自动工具configure.ac或configure：

$ grep -IR man
...

.travis.yml:      cd ffmpeg-3.1.3 && ./configure --prefix=/${DEPS_DIR}/local --d

ble-iconv  && make -j4 install

INSTALL文件没有用：

$ cat INSTALL
Basic Installation
==================

Perform cmake configuration:
cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GIO=ON -DENABLE_THUMBNAILER=ON .

Build the code:
make

Install:
make install

无法使用Cygwin for Windows 10在ffmpegthumbnailer设置文件上使用Makefile
