我正在尝试使用scala-native在os x上构建一个iOS应用程序,并在执行sbt构建时遇到许多问题.任何关于做什么的提示都是受欢迎的.

我使用Xcode目录为iOS文件设置build.sbt,如下所示:

    nativeCompileOptions := Seq("-v",  
    "-isysroot/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator10.3.sdk")

    nativeLinkingOptions := Seq("-v",
    "-I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include",
    "-L/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib",
    "-isysroot/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator10.3.sdk")

• 当对nativelib中包含的c文件进行初始编译时(例如,换行,时间,dyndispatch,gc,posix,eh(c ++),展开和目标)我无法看到为sbt编译添加选项的方法命令行.由于这些编译创建了.o文件(而不是.ll),因此一旦这些编译完成,目标平台就已经设置好了.示例编译如下:

  /Users/nnovod/tools/clang+llvm-4.0.0-x86_64-apple-darwin/bin/clang  
  -I/usr/local/include  
  -I/Users/nnovod/tools/clang+llvm-4.0.0-x86_64-apple-darwin/include  
  -c  
  /Users/nnovod/projects/scalaNative/target/scala-2.11/nativelib/posix.c  
  -o
  /Users/nnovod/projects/scalaNative/target/scala-2.11/nativelib/posix.c.o

• 在编译scala-native代码时,我可以通过nativeCompileOptions添加选项,并添加xcode模拟器sdk目录作为系统根目录(-isysroot .../iPhoneSimulator.10.3.sdk)似乎可以解决问题,尽管有关于"使用x86_64-apple-ios10.3.0覆盖模块目标三元组"

• 链接时存在两个问题:a)找不到gc库(我是否需要为iOS构建一个？Boehm的交叉构建？)b)为MacOS完成的初始编译,现在与iOS完成的编译冲突.以下是sbt生成的链接命令:
