Question

我正在尝试按照包含的Derelict2在Lion上构建installation instructions。当我运行命令make -fmac.mak DC=dmd时，以下库构建正常：

DerelictAllegro
DerelictFMOD
DerelictFT
DerelictGL
DerelictIL
DerelictODE
DerelictOgg
DerelictPA

不幸的是，一旦脚本升级到DerelictSDL，就会吐出以下内容：

make -C DerelictSDL all PLATFORM=mac
dmd -release -O -inline -I../DerelictUtil -c derelict/sdl/sdl.d derelict/sdl/sdlfuncs.d derelict/sdl/sdltypes.d -Hd../import/derelict/sdl

Answer 1

Derelict的最新版本为Derelict3, which is on GitHub。

至于你的错误，看起来你正在为64位编译，这显然在Derelict2中没有被考虑。

您只需修复源代码即可。执行此操作的正确方法是将这些实例更改为使用size_t而不是uint，但在错误消失之前，cast(size_t)这些表达式可能更容易:-)它是不太可能长度超过40亿，所以你应该没事，直到你切换到Derelict3。

Answer 2

尝试以32位模式编译。我相信它是dmd和gdc / gdmd
