Broken Symlinks?

[mickeyl]

When trying to clone (or unzip) the project here on Linux (Ubuntu-derivate), I'm getting lots of errors due to the files not being able to resolve:

You can inspect what was checked out with 'git status'
and retry with 'git restore --source=HEAD :/'

And indeed, something really strange is going on, as the symlink seems to point to the actual contents:

Any idea what's going wrong here?

Hi,

I have no idea what's going on here... I remember that first I commit the symlinks by mistake and I correct this the commit following after.

I don't know why you have this problem

[mickeyl]

I guess you're working on Windows, which handle symlinks a tad bit differently than the rest of the world. Anyways, issuing git config --add core.symlinks false seems to fix it here.
