Building Sourcekit-LSP on a Raspberry Pi

Using Swift
, ,
1

Dear Swift Community,

I'm trying to build Sourcekit-LSP on a Raspberry Pi 3 (Model B V1.2).

I'm using Swift 5.1.5, which was installed from https://github.com/uraimo/buildSwiftOnARM.

I'm having trouble resolving the following errors.

What I Did

First I cloned the Sourcekit-LSP repository using git clone git@github.com:apple/sourcekit-lsp.git && cd sourcekit-lsp, then resolved/updated the packages using swift package resolve, then, after reading the sourcekit-lsp instructions, ran swift build -Xcxx -I/home/lebje/swift/usr/lib/swift -Xcxx -I/home/lebje/swift/usr/lib/swift/Block -j 1 # -j 1 reduces the CPU and memory load on my Raspberry Pi.

What Happened

Build Log

path-to-sourcekit-lsp $ swift build -Xcxx -I/home/lebje/swift/usr/lib/swift -Xcxx -I/home/lebje/swift/usr/lib/swift/Block -j 1 # -j 1 reduces the CPU and memory load on my Raspberry Pi

Looks like __fds_bits has twice as many entries on this platform compared to the other Linux code.

CC @hartbit @benjamin_herzog

I'm not sure what the right way to conditionalize a fix here is - I wonder if this code should just be written in C so that it can use the portable macros.

Try applying the fix from that repo to that file.

That is really unfortunate. I didn’t write this code, only copied it from SwiftPM. It seems that @Aciid already commented with a radar that Swift should provide shims for FD_ macros. This seems to be the right thing to do here but as long as we don’t have that, we should fix it in TSC. Feel free to open a PR with the proposed fix.

@blangmuir: Thank you, but I don't think the code will need to be rewritten in C because the solution provided by @Finagolfin has removed the errors that I was encountering. There is only one error left now (see "Current Error" below).

@Finagolfin: Thank you for your solution. It has removed the errors I was previously experiencing. There is only one error left now (see "Current Error" below).

@benjamin_herzog: If I'm able to successfully build Sourcekit-LSP, I'll see if I can create a pull request.

I think this use of keypath is a Swift 5.2 feature. { $0.value } should work instead.

Note that mixing Swift 5.1 with sourcekit-lsp built from master branch is not guaranteed to work (I think it does currently, but not 100% sure). If you run into any issues with compatibility between swiftpm in your toolchain and libswiftpm in sourcekit-lsp you might want to use our swift-5.1 branch of sourcekit-lsp.

@blangmuir: Thank you for the solution. I'm able to successfully build Sourcekit-LSP.
