swift package pdc crashes

[cove]

Just going through the setup docs and on the swift package pdc command I get errors about mismatched arch (I'm on an M1 Mac FWIW), and then it crashes.

I have TOOLCHAINS set:

export PLAYDATE_SDK_PATH=/Users/cove/Developer/PlaydateSDK
export TOOLCHAINS=org.swift.59202406081a

It appears to be discoverable:

% xcrun --toolchain $TOOLCHAINS  --find swiftc
/Library/Developer/Toolchains/swift-DEVELOPMENT-SNAPSHOT-2024-06-08-a.xctoolchain/usr/bin/swiftc

Here's the abbreviated output:

% swift package pdc

Hi, you should be able to try again using the latest changes to PlaydateKit and PlaydateKitTemplate as well as the latest Swift toolchain. There are a few compiler bugs that I've worked around and everything seems to build now.

That fixed that crash for me!

However I'm getting the "stdlib.h not found error" now:

cove@pico MyGame2 % swift package pdc
[cut]
In file included from /Users/cove/Developer/PlaydateSDK/C_API/buildsupport/setup.c:2:
/Users/cove/Developer/PlaydateSDK/C_API/pd_api.h:13:10: fatal error: 'stdlib.h' file not found
   13 | #include <stdlib.h>
      |          ^~~~~~~~~~
1 error generated.
error: clangFailed(exitCode: 1)

I'm not seeing stdlib.h in the included paths in Package.swift, and when I do force include a path with stdlib.h in it swift seg faults.

e.g. Seems to be in one of these dirs:

cove@pico MyGame2 % find /usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major|grep stdlib.h
/usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/include/ssp/stdlib.h
/usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/include/c++/9.2.1/stdlib.h
/usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/include/c++/9.2.1/tr1/stdlib.h
/usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/include/stdlib.h
/usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/include/machine/stdlib.h

Trying an obvious dir to include:

                    "-Xfrontend", "-disable-objc-interop",
                    "-Xfrontend", "-disable-stack-protector",
                    "-Xfrontend", "-function-sections",
                    "-Xfrontend", "-gline-tables-only",
                    "-Xcc", "-DTARGET_EXTENSION",
                    "-Xcc", "-I", "-Xcc", "\(gccIncludePrefix)/include",
                    "-Xcc", "-I", "-Xcc", "\(gccIncludePrefix)/include-fixed",
                    "-Xcc", "-I", "-Xcc", "\(gccIncludePrefix)/../../../../arm-none-eabi/include",
+                    "-I", "/usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/include"
                    "-I", "\(playdateSDKPath)/C_API",

Crashes:

cove@pico MyGame2 % swift package pdc
zsh: segmentation fault  swift package pdc

Update: Oh wait I see the path is included already with /../../../../arm-none-eabi/include, so I wonder why it can't find the header file?

[richy486]

•                "-I", "/usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/include"
  

Is that just missing a trailing ,?
I tried this too and I'm also getting:

fatal error: 'stdlib.h' file not found
