Furthermore, gcc and clang have slightly different +# behavior regarding include paths when the -I flag contains a relative path and +# symlinks are involved, so this is yet another reason to use absolute paths. +# +# Consequently, we upstreamed a fix for this to the Bear project, see +# https://github.com/rizsotto/Bear/commit/fb1645de9. This fix lived happily in +# the Bear releases 2.1.4, 2.1.5, and 2.2.0, but after that, some "improvements" +# broke the fix again. :-/ Until a new fix has been upstreamed, make sure that +# that you use the right Bear. +# +# To install a working version locally, just do: +# git clone https://github.com/rizsotto/Bear.git && cd Bear && git checkout 2.2.0 && cmake -DCMAKE_INSTALL_PREFIX=$HOME/local/Bear-2.2.0 && make install +# and put $HOME/local/Bear-2.2.0/bin into your PATH or set the make variable +# below accordingly.
