zsh Setup Zsh integration
Install
- Install cmake, make, and g++ (or clang++)
- Install Rust using rustup
cargo install llvmenv
zsh integration
You can swtich LLVM/Clang builds automatically using zsh precmd-hook. Please add a line into your .zshrc
:
source <(llvmenv zsh)
If $LLVMENV_RUST_BINDING
environmental value is non-zero, llvmenv exports LLVM_SYS_60_PREFIX=$(llvmenv prefix)
in addition to $PATH
.
export LLVMENV_RUST_BINDING=1
source <(llvmenv zsh)
This is usuful for llvm-sys.rs users. Be sure that this env value will not be unset by llvmenv, only overwrite.
Concepts
entry
"entry" descrives how to compile LLVM/Clang, and set by entry.toml
at $XDG_CONFIG_HOME/llvmenv
(usually $HOME/.config/llvmenv
).
llvmenv init
generates default setting:
[]
= "https://github.com/llvm-mirror/llvm"
= "https://github.com/llvm-mirror/clang"
= ["X86"]
= "Release"
= 0
= 0
There is also pre-defined entries corresponding to the LLVM/Clang releases:

build
- "build" is a directory where compiled executables (e.g. clang) and libraries are installed.
- They are compiled by
llvmenv build-entry
, and placed at$XDG_DATA_HOME/llvmenv
(usually$HOME/.local/share/llvmenv
). - There is a special build, "system", which uses system's executables.
global/local/prefix
llvmenv prefix
returns the path of the current build (e.g.$XDG_DATA_HOME/llvmenv/llvm-dev
, or/usr
for system build).llvmenv global [name]
sets default build, andllvmenv local [name]
sets directory-local build by creating.llvmenv
text file.- You can confirm which
.llvmenv
sets the current prefix byllvmenv prefix -v
.
