`stm32-uart-echo` Build Error #4

Closed fumoboy007 closed 2 months ago

fumoboy007 commented 5 months ago

I am trying to build thestm32-uart-echo example but not sure what I am doing wrong. I get the following error during the swift-build step:

<unknown>:0: error: unable to load standard library for target 'armv7em-apple-none-macho'

My build command:

TOOLCHAINS="Swift Development Snapshot 2024-04-03 (a)" make

Any ideas?

MaxDesiatov commented 5 months ago

What's the output of swift --version after setting TOOLCHAINS this way? I suspect the value of TOOLCHAINS is wrong, I've never seen it set in this format. IIUC the top-level swift shim expects to be a plist key instead of a human readable version string.

fumoboy007 commented 5 months ago

Hi, @MaxDesiatov! Both Swift Development Snapshot 2024-04-03 (a) and org.swift.59202404031a produce the same result:

% TOOLCHAINS="Swift Development Snapshot 2024-04-03 (a)" swift --version
Apple Swift version 6.0-dev (LLVM cb4f50b342f3cf9, Swift fc5da5342ce965c)
Target: arm64-apple-macosx14.0

Here is the full build log (with some newlines to improve readability):

% TOOLCHAINS=org.swift.59202404031a make

There seem to be a lot of references to Xcode. I wonder if that’s expected.

@fumoboy007 give a try checking the swift-playdate-examples source code, especially this part here where the toolchain is being taken automatically to help in the compilation.

fumoboy007 commented 5 months ago

@unnamedd As I have shown above, I think the correct toolchain is being selected. Thanks for the additional example though!

Same here. Any ideas? -enable-experimental-feature Embedded is not added while building, this might be the reason why standard library is required. If I added this, then swift-mmio dependency fails complaining about String is not available in embedded Swift.

I think (a part of) the problem is the TOOLCHAINS="Swift Development Snapshot 2024-07-07 (a)" syntax -- this doesn't actually select the right toolchain. Use the TOOLCHAINS=org.swift.59202407071a syntax.

I have just tried building the stm32-uart-echo example with the latest downloadable swift.org toolchain and it builds correctly. @fumoboy007 can you try again, too?

fumoboy007 commented 2 months ago

It’s not related to the environment variable syntax. It seems something was broken in the 2024-04-03 Swift toolchain. 2024-07-11 works now.
