All our tools used in the development of Memgraph are manually built for each OS and collected in an archive. Please refer to the memgraph/environment folder for all related code.
<aside>
‼️ NOTE Keep in mind, cargo is also required to build memgraph, follow the official installation guide https://doc.rust-lang.org/cargo/getting-started/installation.html

To download appropriate toolchain archive for your operating system and unpack it automatically, execute
sudo ./environment/os/install_deps.sh prepare TOOLCHAIN_RUN_DEPS
This will unpack latest toolchain to /opt/toolchain-v5 (for OSes that support latest toolchain).
If you have not already installed toolchain dependencies, please check and install required toolchain runtime dependencies by executing
sudo ./environment/os/install_deps.sh check TOOLCHAIN_RUN_DEPS
sudo ./environment/os/install_deps.sh install TOOLCHAIN_RUN_DEPS
Activate the toolchain:
source /opt/toolchain-v5/activate
In case you need to deactivate the toolchain you can run:
deactivate

📢 If you put toolchain on some other path, it’s possible to say to the cmake there the root is, that’s done by setting MG_TOOLCHAIN_ROOT environment variable.
That’s also useful where you have different versions of libraries under system compare to what memgraph build process needs. There was a case with zstd.
