# 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
```
Optionally enable debugging and more verbose logging:
```bash
export CGO_CFLAGS="-g"
```
Get the required libraries and build the native LLM code:
```bash
go generate ./...
```
Then build ollama:
```bash
go build .
```
Now you can run `ollama`:
```bash
./ollama
```
### Linux
#### Linux 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 Linux Build
If you have Docker available, you can build linux binaries with `./scripts/build_linux.sh` which has the CUDA and ROCm dependencies included. The resulting binary is placed in `./dist`
### Windows
Note: The windows build for Ollama is still under development.
Install required tools:
- MSVC toolchain - C/C++ and cmake as minimal requirements
- go version 1.20 or higher
- MinGW (pick one variant) with GCC.
- <https://www.mingw-w64.org/>
- <https://www.msys2.org/>
```powershell
$env:CGO_ENABLED="1"
go generate ./...
go build .
```
#### Windows CUDA (NVIDIA)
In addition to the common Windows development tools described above, install:
- [NVIDIA CUDA](https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html)
