OSX GCC如何指定sfml库源？

2024-01-30

我正在尝试编译一个使用的项目sfml我安装了sfml 2.1通过homebrew像下面这样

unknown542696d2a12b:keeperrl kevzettler$ brew list sfml
    /usr/local/Cellar/sfml/2.1/Frameworks/freetype.framework/ (3 files)
    /usr/local/Cellar/sfml/2.1/Frameworks/sndfile.framework/ (3 files)
    /usr/local/Cellar/sfml/2.1/include/SFML/ (87 files)
    /usr/local/Cellar/sfml/2.1/lib/libsfml-audio.2.1.dylib
    /usr/local/Cellar/sfml/2.1/lib/libsfml-graphics.2.1.dylib
    /usr/local/Cellar/sfml/2.1/lib/libsfml-network.2.1.dylib
    /usr/local/Cellar/sfml/2.1/lib/libsfml-system.2.1.dylib
    /usr/local/Cellar/sfml/2.1/lib/libsfml-window.2.1.dylib
    /usr/local/Cellar/sfml/2.1/lib/ (10 other files)
    /usr/local/Cellar/sfml/2.1/share/SFML/ (3 files)

该项目编译正常，但是当我尝试运行它时出现错误：

unknown542696d2a12b:keeperrl kevzettler$ ./keeper
dyld: Library not loaded: @executable_path/../Frameworks/freetype.framework/Versions/A/freetype
  Referenced from: /usr/local/lib/libsfml-graphics.2.dylib
  Reason: image not found
Trace/BPT trap: 5

看起来 dyld 正在尝试加载不同版本的sfml。比安装的那个homebrew我怀疑这是 OSX 的某些系统默认设置。

编译命令如下所示：

 /usr/local/Cellar/gcc49/4.9.0/bin/gcc-4.9 -Wall -std=c++0x -lstdc++ -ftemplate-depth=1024 -Wno-sign-compare -Wno-unused-variable \

-lsfml-graphics -lsfml-audio -lsfml-window -lsfml-system -lboost_serialization -lz -L/usr/local/Cellar

我试过指定-I and -L标志指向2.1 library

-I/usr/local/Cellar/sfml/2.1/include/SFML/ -I/usr/local/Cellar/sfml/2.1/lib/ -L/usr/local/Cellar

为什么 SFML 公式不能开箱即用？

SFML 的构建是为了使用 freetype 和 libsndfile 框架/Library/Frameworks或从Frameworks文件夹在你的应用程序包 https://developer.apple.com/library/mac/documentation/corefoundation/conceptual/cfbundles/BundleTypes/BundleTypes.html.

您可以找到更多技术细节here https://github.com/Homebrew/homebrew/pull/26091 and there https://github.com/LaurentGomila/SFML/issues/620.

如何在 Mac 上轻松使用 SFML？

这真的很简单：遵循 1:1official guide: SFML 和 Xcode (Mac OS X) http://www.sfml-dev.org/tutorials/2.1/start-osx.php（是的，您可以在 Xcode 之外使用 SFML！）

我真的很想使用酿造配方。我该如何修复它？

首先，好好看看这个问题 https://github.com/LaurentGomila/SFML/issues/620。这将使您对当前简单公式的问题有一个概述。

特别是对于您当前的问题，您将需要使用install_name_tool http://www.manpagez.com/man/1/install_name_tool/修复你的二进制文件。

以下是如何使用 freetype 来完成此操作。 libsndfile 也类似。

install_name_tool -change @executable_path/../Frameworks/freetype.framework/Versions/A/freetype /usr/local/lib/libfreetype.dylib /usr/local/Cellar/sfml/2.1/lib/libsfml-graphics.2.1.dylib

However，这意味着您的应用程序将在中查找 freetype/usr/local/lib。因此，您也必须在客户的计算机上安装 freetype。如果您使用官方安装流程 http://www.sfml-dev.org/tutorials/2.1/start-osx.php并使用 Xcode 模板创建 SFML 应用程序。
