This refines where we extract the LLM libraries to by adding a new OLLAMA_HOME env var, that defaults to `~/.ollama` The logic was already idempotenent, so this should speed up startups after the first time a new release is deployed. It also cleans up after itself. We now build only a single ROCm version (latest major) on both windows and linux. Given the large size of ROCms tensor files, we split the dependency out. It's bundled into the installer on windows, and a separate download on windows. The linux install script is now smart and detects the presence of AMD GPUs and looks to see if rocm v6 is already present, and if not, then downloads our dependency tar file. For Linux discovery, we now use sysfs and check each GPU against what ROCm supports so we can degrade to CPU gracefully instead of having llama.cpp+rocm assert/crash on us. For Windows, we now use go's windows dynamic library loading logic to access the amdhip64.dll APIs to query the GPU information.

Development
Install required tools:
- cmake version 3.24 or higher
- go version 1.22 or higher
- gcc version 11.4.0 or higher
brew install go cmake gcc
Optionally enable debugging and more verbose logging:
# At build time
export CGO_CFLAGS="-g"
# At runtime
export OLLAMA_DEBUG=1
Get the required libraries and build the native LLM code:
go generate ./...
Then build ollama:
go build .
Now you can run ollama:
./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
development and runtime packages.
Typically the build scripts will auto-detect CUDA, however, if your Linux distro
or installation approach uses unusual paths, you can specify the location by
specifying an environment variable CUDA_LIB_DIR to the location of the shared
libraries, and CUDACXX to the location of the nvcc compiler. You can customize
set set of target CUDA architectues by setting CMAKE_CUDA_ARCHITECTURES (e.g. "50;60;70")
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 and ROCm development packages first, as well as cmake and golang.
Typically the build scripts will auto-detect ROCm, however, if your Linux distro
or installation approach uses unusual paths, you can specify the location by
specifying an environment variable ROCM_PATH to the location of the ROCm
install (typically /opt/rocm), and CLBlast_DIR to the location of the
CLBlast install (typically /usr/lib/cmake/CLBlast). You can also customize
the AMD GPU targets by setting AMDGPU_TARGETS (e.g. AMDGPU_TARGETS="gfx1101;gfx1102")
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.
Advanced CPU Settings
By default, running go generate ./... will compile a few different variations
of the LLM library based on common CPU families and vector math capabilities,
including a lowest-common-denominator which should run on almost any 64 bit CPU
somewhat slowly. At runtime, Ollama will auto-detect the optimal variation to
load. If you would like to build a CPU-based build customized for your
processor, you can set OLLAMA_CUSTOM_CPU_DEFS to the llama.cpp flags you would
like to use. For example, to compile an optimized binary for an Intel i9-9880H,
you might use:
OLLAMA_CUSTOM_CPU_DEFS="-DLLAMA_AVX=on -DLLAMA_AVX2=on -DLLAMA_F16C=on -DLLAMA_FMA=on" go generate ./...
go build .
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 - You must build from a "Developer Shell" with the environment variables set
- go version 1.22 or higher
- MinGW (pick one variant) with GCC.
$env:CGO_ENABLED="1"
go generate ./...
go build .
Windows CUDA (NVIDIA)
In addition to the common Windows development tools described above, install CUDA AFTER you install MSVC.
