Cannot install OpenCV 4 with new compiler

To help us debug your issue please explain:

• I’ve read the CONTRIBUTING guide.
• I’ve specified the Conan version, operating system version and any tool that can be relevant.
• I’ve explained the steps to reproduce the error or the motivation/use case of the question/suggestion.

I’m trying to install OpenCV 4.1 on Ubuntu 18.04 with GCC 8.3 on Windows Subsystem for Linux. I execute the following line:

conan install opencv/4.1.1@conan/stable -s compiler.version=8.3 --build missing

But the install always fails with the following error:

$ conan install opencv/4.1.1@conan/stable -s compiler.version=8.3 --build missing
Configuration:
[settings]
arch=x86_64
arch_build=x86_64
build_type=Release
compiler=gcc
compiler.libcxx=libstdc++11
compiler.version=8.3
os=Linux
os_build=Linux

Installing OpenCV without specifying the compiler works well:

conan install opencv/4.1.1@conan/stable […]

I got the exact same error message but for a different package. After sinking a lot of time into debugging the issue, it turned out that the virusscanner was responsible for this error. After turning off virus scanning everything worked fine…

Then maybe you could try to change the CONAN_USER_HOME (https://docs.conan.io/en/latest/reference/env_vars.html#conan-user-home) to see if the permissions issues persist.
