In particular, leaving cmake-rs to its own devices results in CMake setting Visual Studio 17 2022 as generator, and with our Build Tools installed in a non-standard location, results in a build failure.

Our build should succeed with whichever generator is automatically selected by cmake-rs (typically, it's "Ninja" or "Visual Studio 17 2022"). But if our build logic were to show a preference for "Ninja", wouldn't Ninja likewise be unable to locate your MSVC compiler given that your Build Tools are installed in a non-standard location? Or does the build environment provide context that allows for Ninja to find the compiler while cmake-rs does not?

This potentially could be an issue we could file with cmake-rs were it failing to locate require build tooling in an environment where it should be able to.

Neither CMake nor MSVC are LongPathAware; since our CI infrastructure builds inside an user-level folder, we are suddenly exceeding PATH_MAX

I'm not sure this is fixable given that the crypto operations in AWS-LC are written in C/Assembly. I'm assuming that compiling C-code to an *-windows-msvc target requires an MSVC compiler. (Is clang-cl also unable to handle longer paths?) Alternatively, you might try to build our library targeting *-windows-gnu?

Hi @justsmth !

Or does the build environment provide context that allows for Ninja to find the compiler while cmake-rs does not?

The build context is enough, we're already running under a developer shell. For some reason CMake (not cmake-rs) breaks down when trying to initialize the shell again, which happens when forcing the VS2022 generator as is currently done.

But if our build logic were to show a preference for "Ninja", wouldn't Ninja likewise be unable to locate your MSVC compiler given that your Build Tools are installed in a non-standard location?

Preferring Ninja would aid in debugging build failures, as the compiler line gets printed upon failure. It is easy to detect the developer shell and do so too, as in the linked CMake code.

Alternatively, you might try to build our library targeting *-windows-gnu?

We build both for MSVC and for MinGW. The MinGW build is prone to failure for multiple reasons: apart from the PATH_MAX issue, the use of Makefiles means also a hard require for a MSYS2 environment or similar. The workaround here was to force Ninja (as we have it available for all OSes, and we run with appropriate PATH entries set for each compiler) and compress the path to make extra space.

I'm not sure this is fixable given that the crypto operations in AWS-LC are written in C/Assembly.

The workaround was meant only to support CMake's setup process, while also cargo vendoring the source code in a build from the user folder.

C/Assembly works just fine, we have been able to continue targeting all platforms even with the recent changes, and NASM compilation has not introduced any issues either.
