SublimeClang is a cool and useful extension for SublimeText which enables IDE features for C++ programmers.
Here are the installation instructions for Linux from their github page.
There are two problems with the installation on Archlinux.
SublimeText looks for Python 2.6. Archlinux has Python 3 and Python 2.7,
Install python26 from AUR.
Create a symlink to the new Python 2.6 installation in the right place for SublimeText to find, as root (sorry, I don’t know how to solve it without creating a symlink as root).
ln -s /lib/python2.6/ /opt/sublime-text/lib/python2.6
When trying to build libcache the build environment won’t find libclang.so and will try to build it and fail.
Copy the file to a place where it will be found.
cp /usr/lib/llvm/libclang.so ~/.config/sublime-text-2/Packages/SublimeClang
Now clean the build environment if needed and run the cmake and make commands as written in the instructions.
It should work now. Tested on Archlinux 64 bit.
