# Development

- Install cmake or (optionally, required tools for GPUs)
- run `go generate ./...`
- run `go build .`

Install required tools:

- cmake version 3.24 or higher
- go version 1.20 or higher
- gcc version 11.4.0 or higher

```bash
brew install go cmake gcc
```

Get the required libraries:

```bash
go generate ./...
```

Then build ollama:

```bash
go build .
```

Now you can run `ollama`:

```bash
./ollama
```

## Building on Linux with GPU support


### Linux/Windows CUDA (NVIDIA)
*Your operating system distribution may already have packages for NVIDIA CUDA. Distro packages are often preferable, but instructions are distro-specific. Please consult distro-specific docs for dependencies if available!*

Install `cmake` and `golang` as well as [NVIDIA CUDA](https://developer.nvidia.com/cuda-downloads) development and runtime packages.
Then generate dependencies:
```
go generate ./...
```
Then build the binary:
```
go build .
```

### Linux ROCm (AMD)
*Your operating system distribution may already have packages for AMD ROCm and CLBlast. Distro packages are often preferable, but instructions are distro-specific. Please consult distro-specific docs for dependencies if available!*

Install [CLBlast](https://github.com/CNugteren/CLBlast/blob/master/doc/installation.md) and [ROCm](https://rocm.docs.amd.com/en/latest/deploy/linux/quick_start.html) developement packages first, as well as `cmake` and `golang`.
Adjust the paths below (correct for Arch) as appropriate for your distributions install locations and generate dependencies:
```
CLBlast_DIR=/usr/lib/cmake/CLBlast ROCM_PATH=/opt/rocm go generate ./...
```
Then build the binary:
```
go build .
```

ROCm requires elevated privileges to access the GPU at runtime.  On most distros you can add your user account to the `render` group, or run as root.

## Containerized Build

If you have Docker available, you can build linux binaries with `./scripts/build_linux.sh` which has the CUDA and ROCm dependencies included.
