[Error 267] (Windows) The directory name is invalid. If 'cargo.target-dir' contains '../'

[alt-net]

Hello everyone!
I overridden taget-dir for my project, so “.cargo/config.toml” looks like this:

[build]
target = "xtensa-esp32-espidf"
target-dir = "..\\arcnet-target" (the same for "../arcnet-target")

An error occurs during the build:

error: linking with `ldproxy` failed: exit code: 1

Is there any way to fix it for Windows?

[ivmarkov]

I wonder what is this V drive:

• Option A - a real drive
• Option B - a virtual "subst" drive hiding a long directory path that the build clearly warns you should not do
  ?

[alt-net]

V is just real hard drive partition

[ivmarkov]

I have no ideas then. Maybe you can play a bit with e.g. absolute path for your target dir to figure out what is the actual problem in the first place. I.e. is it the relative path, or something else.
