Exporting to Makefile fails to build on Windows

[SeppoTakalo]

Description

• Type: Bug
• Priority: Minor

Bug

Target
Any

Toolchain:
Any Makefile based export.

Expected behavior
mbed export -m <board> -i make_gcc_arm
make

Actual behavior
Error code:
make (e=87): The parameter is incorrect.

This is produced because the final link command is 44,252 characters long.

Windows CreateProcess() only accepts command line maximum length to be 32,768 characters. See here.

Similar issue described here: https://stackoverflow.com/questions/12598933/ndk-build-createprocess-make-e-87-the-parameter-is-incorrect

Steps to reproduce
Import mbed-os-example-mesh-minimal
mbed export -m <board> -i make_gcc_arm

Workarounds

1. Don't use Makefile builds on Windows.

Yeah, there's not a whole lot I can do about that. Known issue?

FYI @adbridge

[theotherjimmy]

@MarceloSalazar What do you want Anna to do about this? Is there something I can do?

[MarceloSalazar]

I've just wanted Anna to be aware of this, as may need to go to the known issue list.

[theotherjimmy]

I can add it. Would you like a known issue?

[theotherjimmy]

Known issue added.

Is there a workaround for this based on how close to root you place the exported project or are all these paths relative to the extract point on disc and due to the amount of features and source code and path expansion in Mbed OS for a particular target?

[theotherjimmy]

@sg- I'd have to check, but I think you may be able to work around this by extracting into an already short path. That being said, if the project exceeds the path limit without any prefixes, then there is no workaround (other than use another exporter, or use Linux)

[SeppoTakalo]

I cannot remember whether it used relative or absolute path names...
I would assume that relative, which would mean that no workarounds exists, other than using proper operating system.

[sg-]

proper operating system.

🤣

[theotherjimmy]

XD "proper" operating system

ARMmbed/mbed-os-example-bootloader#58 is a duplicate.
