# Building timelords
|
|
|
|
The Linux and MacOS chiavdf binary wheels currently exclude an executable
|
|
required to run a [Timelord](https://github.com/Chia-Network/chia-blockchain/wiki/Timelords).
|
|
If you want to run a Timelord on Linux or MacOS, you must install the wheel
|
|
from source (which may require some additional development packages) while in
|
|
the virtual environment.
|
|
|
|
```bash
|
|
. ./activate
|
|
|
|
chmod +x ./install-timelord.sh
|
|
sh install-timelord.sh
|
|
```
|
|
|
|
If the compile fails, it's likely due to a missing dependency. The script
|
|
[install-timelord.sh](https://github.com/Chia-Network/chia-blockchain/blob/main/install-timelord.sh)
|
|
attempts to install required build dependencies for Linux and MacOS before
|
|
invoking pip to build from the source python distribution of chiavdf.
|
|
|
|
The `install-timelord.sh` install script leverages two environmental variables
|
|
that the chiavdf wheels can use to specify how to build. The service that the
|
|
Timelord uses to run the VDF and prove the Proof of Time is `vdf_client` and
|
|
`vdf_bench` is a utility to get a sense of a given CPU's iterations per second.
|
|
|
|
- To build vdf_client set the environment variable BUILD_VDF_CLIENT to "Y".
|
|
`export BUILD_VDF_CLIENT=Y`.
|
|
- Similarly, to build vdf_bench set the environment variable BUILD_VDF_BENCH
|
|
to "Y". `export BUILD_VDF_BENCH=Y`.
|
|
|
|
Building and running Timelords in Windows x86-64 is not yet supported.
