代码块 osx 快板
code blocks osx allegro
我是 C++ 的新手，由于 uni 的要求，我们都在使用代码块。我是在10.10.5 OS X上用的。现在要做一个项目，用到了allegro5库，但是安装不了！我花了很多时间尝试学习 http://partitionseven.blogspot.com/2011/01/compiling-allegro-5-with-mac-os-x-snow.html 等不同的教程，但都没有成功。
有什么办法让它工作吗？

我在指定 clang 工具时第一次遇到问题 - 我的 mac /Developer/usr/bin/clang 上没有这样的目录。我只能直接在 finder 中找到 usr/bin/clang，但是文件夹 usr 是灰色的-这意味着什么吗？
只有在单击 Xcode->show contents 时，我才能找到此路径 /Developer/usr/bin/clang。所以这是第一件事，与教程中的不完全一样。我仍然能够 运行 CMAKE 但我得到这样的日志：

谢谢@MikeKinghan，看来我更进了一步——我没有收到错误。但是我打开了代码块，粘贴了示例代码（教程中的代码），并且在编译时出现错误

当我 运行 来自终端的测试应用程序

它起作用了——我遇到了黑屏。所以可能我必须“用代码块加入图书馆。任何想法 - 我只找到了 windows.
的教程
由于 SO 限制，我无法回复，但有一种可能：您的 Allegro 库是为 i386 构建的，不包括 x86_64 架构。您可以在命令行上检查库，但它不会总是告诉您您拥有什么，除非您同时拥有 i386 和 x86_64。你这样做：
file liballegro.a 或 file liballegro.dylib
如果它说的是 x86_64 那我就错了。如果不是，那可能是问题所在。然后您有两个选择：将 Allegro 构建为 x86_64 或将您的程序构建为 i386。要将 Allegro 构建为 x86_64 和 i386，请将以下内容添加到您的 CMake 命令中，如下所示：
cmake .. -DCMAKE_OSX_ARCHITECTURES="x86_64;i386" ...
或者只在 cmake-gui 中指定该变量。您可以通过删除它和分号来省略一个或另一个。
现在要构建具有特定体系结构的程序，如果您像链接的教程一样从命令行使用 gcc，请使用 -m 开关。要为 i386 构建，请使用 -m32 并为 x86_64 构建使用 -m64（或者你可以对两者都使用 -arch i386 -arch x86_64 我相信（不确定并且不在 Mac 现在。）所以你的命令是：
gcc -m64 ... 其中...与之前相同。
