#18114 go: environment-specific dependencies due to conditional compilation Issue created by tdyas Once #18113 lands,

go_binary

will support non-local environments but there is a bug, however: Dependencies for packages in the Go SDK (and Go packages in general) can vary between local and non-local environments due to conditional compilation of sources . For example, the

runtime

package in the Go SDK only uses the

runtime/internal/syscall

package on Linux but not macOS. Currently, those dependencies are setup statically based on the local environment while creating the

//:default_go_sdk

synthetic target. (Dependency inference is not used since it would result in a rule graph cycle.) Potential solutions: 1. Keep the synthetic target for now to avoid exposing

go_sdk

target type to users before we are ready. The code in

build_pkg_target.py

will lookup Go SDK dependencies dynamically without relying on dependency inference or the static setup of the synthetic target and its generated targets. 2. Explore whether introducing a

go_sdk

target type and enabling dependency inference would solve the problem. If

go_sdk

is not a synthetic target, then this might avoid the rule graph error which I encountered previously. pantsbuild/pants
