Improve cross compiling support by messense · Pull Request #158 · rust-lang/cmake-rs

messense · 2022-07-26T10:42:08Z

This PR changes cmake-rs to fill out CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_PROCESSOR based CARGO_CFG_TARGET_OS and CARGO_CFG_TARGET_ARCH when cross compiling while CMAKE_TOOLCHAIN_FILE and CMAKE_SYSTEM_NAME isn't set by user.

It's tested on CI using cross.

Closes #75
Closes #80
Closes #151

+                    }
+                } else if target.contains("solaris") {
+                    if !self.defined("CMAKE_SYSTEM_NAME") {
+                        self.define("CMAKE_SYSTEM_NAME", "SunOS");


We can also address #151 by removing this if it's desirable.

Yes, please!

Fixes #151

This looks great. Thanks for improving the CI too.

…Fixes rust-lang#173 In rust-lang#158, better support for using CMake's cross-compilation facilities was added. This made the workaround added in rust-lang#110 for iOS not only unnecessary, but actively harmful, in that it runs afoul of SDK validation checks in the CMake iOS codepath.

I'm afraid this broke no-toolchain cross-compilation using Visual Studio, from an x86_64 Windows host to aarch64-pc-windows-msvc. Things are a bit clunky there in general (the existing support goes through platforms and does not set CMAKE_SYSTEM_PROCESSOR), but it was working in 1.48.0 (and I'm afraid we hadn't been testing with new crate versions, so we didn't discover this sooner).

(Specifically, the auto-search for CMAKE_C_COMPILER and CMAKE_CXX_COMPILER doesn't kick in, even though it works fine for a non-cross-compile MSVS generator build.)

jrose-signal · 2023-05-11T22:38:22Z

Workaround: set CMAKE_SYSTEM_NAME to an empty string, which counts as defined for this crate, but unset for CMake itself.

jrose-signal · 2023-05-31T19:22:05Z

Turns out this also broke cross-compiling to Mac Catalyst targets (*-apple-ios-macabi), because CMake doesn't like having CMAKE_SYSTEM_NAME set to "iOS" while compiling against a macOS sysroot. That should probably eventually be fixed in CMake itself, but for now setting CMAKE_SYSTEM_NAME back to "Darwin" does work, at least for simple libraries. I don't know if you want to put that in this crate, though.

EDIT (months later): here's CMake not deciding what to do about Catalyst, which isn't cmake-rs's fault.
