Build
Prerequisites
To build the TensorRT-OSS components, you will first need the following software packages.
TensorRT GA build
- TensorRT v11.2.1.2
- Available from direct download links listed below
System Packages
Optional Packages
NCCL >= v2.19, < v3.0 — only when building with multi-device support (-DTRT_BUILD_ENABLE_MULTIDEVICE=ON) for the sampleDistCollective sample.
Containerized build
PyPI packages (for demo applications/tests)
Code formatting tools (for contributors)
NOTE: onnx-tensorrt, cub, and protobuf packages are downloaded along with TensorRT OSS, and not required to be installed.
Downloading TensorRT Build
Download TensorRT OSS
git clone -b main https://github.com/nvidia/TensorRT TensorRT
cd TensorRT
git submodule update --init --recursive
(Optional - if not using TensorRT container) Specify the TensorRT GA release build path
If using the TensorRT OSS build container, TensorRT libraries are preinstalled under /usr/lib/x86_64-linux-gnu and you may skip this step.
Else download and extract the TensorRT GA build from NVIDIA Developer Zone with the direct links below:
Example: Ubuntu 22.04 on x86-64 with cuda-13.3
cd ~/Downloads
tar --zstd -xvf TensorRT-Enterprise-11.2.1.2-Linux-x86_64-cuda-13.3-Release-external.tar.zst
export TRT_LIBPATH=`pwd`/TensorRT-11.2.1.2/lib
Example: Windows on x86-64 with cuda-12.9
Expand-Archive -Path TensorRT-Enterprise-11.2.1.2-Windows-amd64-cuda-12.9-Release-external.zip
$env:TRT_LIBPATH="$pwd\TensorRT-11.2.1.2\lib"
Setting Up The Build Environment
For Linux platforms, we recommend that you generate a docker container for building TensorRT OSS as described below. For native builds, please install the prerequisite System Packages.
Generate the TensorRT-OSS build container.
Example: Ubuntu 24.04 on x86-64 with cuda-13.3 (default)
./docker/build.sh --file docker/ubuntu-24.04.Dockerfile --tag tensorrt-ubuntu24.04-cuda13.3
Example: Rockylinux8 on x86-64 with cuda-13.3
./docker/build.sh --file docker/rockylinux8.Dockerfile --tag tensorrt-rockylinux8-cuda13.3
Example: Ubuntu 24.04 cross-compile for Jetson (aarch64) with cuda-13.3 (JetPack SDK)
./docker/build.sh --file docker/ubuntu-cross-aarch64.Dockerfile --tag tensorrt-jetpack-cuda13.3
Example: Ubuntu 24.04 on aarch64 with cuda-13.3
./docker/build.sh --file docker/ubuntu-24.04-aarch64.Dockerfile --tag tensorrt-aarch64-ubuntu24.04-cuda13.3
Launch the TensorRT-OSS build container.
Example: Ubuntu 24.04 build container
./docker/launch.sh --tag tensorrt-ubuntu24.04-cuda13.3 --gpus all
NOTE:
1. Use the --tag corresponding to build container generated in Step 1.
2. NVIDIA Container Toolkit is required for GPU access (running TensorRT applications) inside the build container.
3. sudo password for Ubuntu build containers is 'nvidia'.
4. Specify port number using --jupyter <port> for launching Jupyter notebooks.
5. Write permission to this folder is required as this folder will be mounted inside the docker container for uid:gid of 1000:1000.
Building TensorRT-OSS
Generate Makefiles and build
Example: Linux (x86-64) build with default cuda-13.3
cd $TRT_OSSPATH
mkdir -p build && cd build
cmake .. -DTRT_LIB_DIR=$TRT_LIBPATH -DTRT_OUT_DIR=`pwd`/out
make -j$(nproc)
Example: Linux (aarch64) build with default cuda-13.3
cd $TRT_OSSPATH
mkdir -p build && cd build
cmake .. -DTRT_LIB_DIR=$TRT_LIBPATH -DTRT_OUT_DIR=`pwd`/out -DCMAKE_TOOLCHAIN_FILE=$TRT_OSSPATH/cmake/toolchains/cmake_aarch64-native.toolchain
make -j$(nproc)
Example: Native build on Jetson Thor (aarch64) with cuda-13.3
cd $TRT_OSSPATH
mkdir -p build && cd build
cmake .. -DTRT_LIB_DIR=$TRT_LIBPATH -DTRT_OUT_DIR=`pwd`/out -DTRT_PLATFORM_ID=aarch64
CC=/usr/bin/gcc make -j$(nproc)
NOTE: C compiler must be explicitly specified via CC= for native aarch64 builds of protobuf.
Example: Ubuntu 24.04 Cross-Compile for Jetson Thor (aarch64) with cuda-13.3 (JetPack)
cd $TRT_OSSPATH
mkdir -p build && cd build
cmake .. -DTRT_LIB_DIR=$TRT_LIBPATH -DCMAKE_TOOLCHAIN_FILE=$TRT_OSSPATH/cmake/toolchains/cmake_aarch64_cross.toolchain
make -j$(nproc)
Example: Ubuntu 24.04 Cross-Compile for DriveOS (aarch64) with cuda-13.3
cd $TRT_OSSPATH
mkdir -p build && cd build
cmake .. -DTRT_LIB_DIR=$TRT_LIBPATH -DCMAKE_TOOLCHAIN_FILE=$TRT_OSSPATH/cmake/toolchains/cmake_aarch64_dos_cross.toolchain
make -j$(nproc)
Example: Native builds on Windows (x86) with cuda-13.3
cd $TRT_OSSPATH
New-Item -ItemType Directory -Path build
cd build
cmake .. -DTRT_LIB_DIR="$env:TRT_LIBPATH" -DTRT_OUT_DIR="$pwd\\out"
msbuild TensorRT.sln /property:Configuration=Release -m:$env:NUMBER_OF_PROCESSORS
NOTE: The default CUDA version used by CMake is 13.3. To override this, for example to 12.9, append -DCUDA_VERSION=12.9 to the cmake command.
Required CMake build arguments are:
TRT_LIB_DIR: Path to the TensorRT installation directory containing libraries.TRT_OUT_DIR: Output directory where generated build artifacts will be copied.
Optional CMake build arguments:
CMAKE_BUILD_TYPE: Specify if binaries generated are for release or debug (contain debug symbols). Values consists of [Release] | DebugCUDA_VERSION: The version of CUDA to target, for example [12.9.9].CUDNN_VERSION: The version of cuDNN to target, for example [8.9].PROTOBUF_VERSION: The version of Protobuf to use, for example [3.20.1]. Note: Changing this will not configure CMake to use a system version of Protobuf, it will configure CMake to download and try building that version.CMAKE_TOOLCHAIN_FILE: The path to a toolchain file for cross compilation.BUILD_PARSERS: Specify if the parsers should be built, for example [ON] | OFF. If turned OFF, CMake will try to find precompiled versions of the parser libraries to use in compiling samples. First in ${TRT_LIB_DIR}, then on the system. If the build type is Debug, then it will prefer debug builds of the libraries before release versions if available.BUILD_PLUGINS: Specify if the plugins should be built, for example [ON] | OFF. If turned OFF, CMake will try to find a precompiled version of the plugin library to use in compiling samples. First in ${TRT_LIB_DIR}, then on the system. If the build type is Debug, then it will prefer debug builds of the libraries before release versions if available.BUILD_SAMPLES: Specify if the samples should be built, for example [ON] | OFF.BUILD_SAFE_SAMPLES: Specify if safety samples should be built, for example [ON] | OFF.TRT_SAFETY_INFERENCE_ONLY: Specify if only build the safety inference components, for example [ON] | OFF. If turned ON, all other components will be turned OFF except BUILD_SAFE_SAMPLES.TRT_PLATFORM_ID: Bare-metal build (unlike containerized cross-compilation). Currently supported options: x86_64 (default).TRT_BUILD_ENABLE_MULTIDEVICE: Enable the multi-device sample (sampleDistCollective). Use -DTRT_BUILD_ENABLE_MULTIDEVICE=ON to build it; requires NCCL >= v2.19, < v3.0.TRT_BUILD_TESTING : Build gTests for samples. Requires gtest if available; otherwise fetches googletest at configure time.
