Change package version in buildroot.

Hello.

I'm trying to change version of package in buildroot. I've copied files from package/squashfs to proper path in $BR2_EXTERNAL and changed version of sources to 4.2. When building I've warnings about overriding commands in new files but this is ok. The problem is when buildroot try to extract package. It making wrong build folder (it uses version string from original buildroot package) in output/build and cannot extract package.

Output from make V=1:

Thanks for the help and sorry for my english.

Dear Piotr Rudzki,

This is not supported. The $BR2_EXTERNAL mechanism can only be used to add distinct packages from the ones available in Buildroot itself. You cannot use it to override packages that exist in Buildroot with the same name.

Possible solutions are:

*) Create a new package with a different name in your $BR2_EXTERNAL
directory.

*) Change Buildroot itself, and keep your changes in a separate branch.

Best regards,

Thomas
