'Failed to import bridging header' #7

Open ewmailing opened 7 years ago

ewmailing commented 7 years ago

Hi, I've been doing a lot of work to get Swift usable in a cross-platform way (Mac, iOS, Linux, Android, Raspberry Pi). I heard about this Windows port and the Swift for Windows project at https://swiftforwindows.codeplex.com, so I thought I would give it a try.

Using the prebuilt Visual Studio 2015 binaries for the command line swift and swiftc executables provided by the Swift for Windows page, I am able to build and run a trivial Swift program (e.g. print("Hello World").

So my next step is to use a bridging header. The way I'm approaching cross-platform is that I have a bunch of already cross-platform C libraries (e.g. SDL) which I bind to Swift. Then you can write cross-platform Swift code. But for this to work, I need a bridging header.

When I try specifying a bridging header, I get the error "failed to import bridging header".

I found there was an existing similar question about this that was closed. https://github.com/tinysun212/swift-windows/issues/3

However, the recommendation didn't work for me, but even if it did, I really need to be able to specify my own bridging header like the poster wanted to do.

To give you a more concrete example of what my build sequence looks like and what I want to do, below is a simple test program of mine when I build on Linux. (All the other platforms pretty much have the same sequence. For Visual Studio, I would change cc -c to cl.exe /c and the final link phase of swiftc to link.exe.)

Basically I would like to know how to get the -import-objc-header switch to work correctly so I can follow the same build semantics as the other platforms.

Thank you for your time.

Could you try this on latest Cygwin port ? (https://github.com/tinysun212/swift-windows/releases/tag/swift-cygwin-20160913)

@ewmailing, Could you try this on latest MinGW-w64 port ? (https://swiftforwindows.github.io/)
