如何使用CMake 2.8编译Allegro 4.9.14

Question

我从来没有使用CMake编译过程序。我已经下载了Allegro的最新SVN，并多次尝试编译，但没有成功。我在互联网上找遍了，没有找到任何有用的东西。我选择在Visual Studio 9 2008中编译它。我真的不知道我必须在哪里链接源代码和构建。Allegro文件令人困惑。我不知道这是否有用，但我也拿到了lib文件。如果有人知道我应该如何链接这些文件以正确编译，我将非常高兴。

下面是CMakeCash.Text的内容：

# This is the CMakeCache file.
# For build in directory: c:/lib/Allegro4.9
# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
# If you do want to change a value, simply edit, save, and exit the editor.
# The syntax for the file is as follows:
# KEY:TYPE=VALUE
# KEY is the name of a variable in the cache.
# TYPE is a hint to GUI's for the type of VALUE, DO NOT EDIT TYPE!.
# VALUE is the current value for the KEY.

Answer 1

如果cmake失败了，它应该告诉你哪里出了问题，比如:你是否缺少所需的依赖项。

如果cmake本身没有失败，请发布您在cmake和/或编译器中看到的实际错误。

编辑：

这就对了，你的错误：

找不到DINPUT (缺少: DINPUT_INCLUDE_DIR DINPUT_LIBRARY) CMakeLists.txt:565处出现CMake错误(消息)：Windows端口需要DirectInput (未找到)。

这是一个常见的问题，在较新的版本中得到了修复。4.9.14是古老的。请升级到最新版本，或者直接从SVN获取。

Answer 2

首先，从MSVC命令提示符运行cmake，而不是常规的命令提示符。然后将INCLUDE和LIB环境变量设置为指向您的directx安装。例如：

set INCLUDE=C:\Program Files\Microsoft (2009年8月)\Include set LIB=C:\Program Files\Microsoft (2009年8月)\ DirectX \x86

注意没有引号(")。不要使用引号。然后删除CMakeCache.txt并再次运行cmake，它应该会找到directx。
