git - Switch between branches gives me error -

every time switch between branches error.

i've done couple of times:

https://help.github.com/articles/dealing-with-line-endings

    git rm --cached -r . # remove index.   git reset --hard # write both index , working directory git's database.   git add . # prepare make commit staging files normalized.  # chance inspect files never normalized. should  # lots of messages like: "warning: crlf replaced lf in file."  git commit -m "normalize line endings" # commit 

and problem still occurs.

my .gitattribute file looks this:

# set default behaviour, in case users don't have core.autocrlf set. * text=auto  # explicitly declare text files want normalized , converted  # native line endings on checkout. *.c text *.h text  # declare files have crlf line endings on checkout. *.sln text eol=crlf  # denote files binary , should not modified. *.png binary *.jpg binary 

i error:

"error: local changes following files overwritten checkout:"

error: local changes following files overwritten checkout:

this occurs because files have not been committed repository. git add . adds tracked files in current directory. fix this, could:

• add each file manually (git add <file>), giving full path file,
• use git add -a.

here man-page git-add.
