説明

I am trying to setup cross-compilation with SCons where Conan provides the cross-compiler as a binary package. So, I have created a cross-compiler package which works fine with CMAKE when I add it as tool_requires and set the correct host profile.

For SCons however I am not sure how I can add the location of the cross-compiler binaries to the build environment. The SConscript_conan file does not contain anything regarding the packages installed via tool_requires. I would expect that they show up, so that I can add the BINPATH to the SCons environment. I can't add the pakckage as normal requires because then the build and host environments don't match anymore.

Does anyone have a suggestion what the recommend approach is for cross-compilation with SCons?

調査方針
Investigate how Conan's SCons generator currently handles tool requires. The issue suggests that binaries from tool requires are not exposed to the SCons environment. Look at the SCons generator source code in Conan (likely conan/tools/scm or similar) to understand how dependencies are added. Consider adding an option to include tool requires paths, or document a workaround using environment variables in the SCons script. Engage with the assignee (@mention) to clarify the expected behavior and potential implementation.
