Question

我无法让程序运行，我觉得这是因为Mac OS X决定使用错误的库。我希望它使用SDL_image，但我认为它选择使用SDL-1.2。有没有办法强制它使用SDL_image？如果它有帮助，我正在尝试运行用Go程序语言编写的程序。

我已经尝试修改DYLD_LIBRARY_PATH变量，因为我怀疑dyld可能与它有关，但它不起作用。我发现的与此问题相关的其他所有内容都只是错误日志，而不是如何修复它。

您是否尝试在可执行文件上使用install_name_tool -change以使库引用具有绝对路径？

您还可以尝试使用install_name_tool更改可执行文件的rpath，如果存在则删除/ opt / local。或者如果没有rpath，你可以尝试添加/ usr / local / lib并更改库引用以使用@rpath /（参见“man dyld”和“man install_name_tool”）

您也可以从MacPorts切换到Homebrew，然后您的所有开源软件都位于/ usr / local下，您就不会遇到这类问题。

如何定义在Mac OS X上使用哪个库？
