Ctags generates indices of symbol definitions in source files. It started its life as part of the BSD Unix, but there are several more modern flavors. Zoekt supports both exuberant ctags and universal-ctags.
It is strongly recommended to use Universal Ctags, version db3d9a6
or newer, running on the Linux platform.
From this version on, universal ctags will be called using seccomp, which guarantees that security problems in ctags cannot escalate to access to the indexing machine.
Use the following invocation to compile and install universal-ctags:
sudo apt-get install pkg-config autoconf \ libseccomp-dev libseccomp \ libjansson-dev libjansson ./autogen.sh LDFLAGS=-static ./configure --enable-json --enable-seccomp make -j4 # create tarball NAME=ctags-$(date --iso-8601=minutes | tr -d ':' | sed 's|\+.*$||')-$(git show --pretty=format:%h -q) mkdir ${NAME} cp ctags ${NAME}/universal-ctags tar zcf ${NAME}.tar.gz ${NAME}/
