# 用 Visual Studio 编译
|
||||
|
||||
[TOC]
|
||||
|
||||
## 预先准备
|
||||
|
||||
Visual Studio 2015 / 2017 / 2019 / 2022 Preview 的 Community Edition 版本， 使用动态的 CRT 运行库
|
||||
|
||||
CMake, 推荐 >= 3.17 的版本
|
||||
|
||||
## 开始编译
|
||||
|
||||
### 最简编译
|
||||
|
||||
https://github.com/Tencent/ncnn.git
|
||||
|
||||
#### 命令提示符版本
|
||||
|
||||
```batch
|
||||
mkdir build-vs2019
|
||||
cd build-vs2019
|
||||
cmake -G "Visual Studio 16 2019" -A x64 ..
|
||||
cmake --build . --config Release
|
||||
cmake --install . --config Release
|
||||
cmake --build . --config Debug
|
||||
cmake --install . --config Debug
|
||||
```
|
||||
|
||||
会安装在 build-vs2019/install 里头，debug 版本的库会带有 `d` 后缀。
|
||||
|
||||
#### x64 本机工具命令提示符 版本 （VS2022无X64）
|
||||
ncnn
|
||||
protobuf参照后文定义参数
|
||||
|
||||
```batch
|
||||
mkdir build-vs2019
|
||||
cd build-vs2019
|
||||
cmake ..
|
||||
cmake --build .
|
||||
cmake --install . --config Debug
|
||||
|
||||
//默认build生成Debug版本；默认install安装Relase版本。 参照命令提示符版本
|
||||
```
|
||||
|
||||
|
||||
### 编译安装带 Vulkan 支持的 ncnn 库
|
||||
|
||||
#### 设备和 Vulkan 准备
|
||||
确认设备支持 Vulkan， 安装显卡驱动。
|
||||
|
||||
下载和安装 Vulkan SDK: https://vulkan.lunarg.com/sdk/home
|
||||
|
||||
连同子模块一起，获取源码：
|
||||
- 可从 http://github.com/Tencent/ncnn/releases 找到 "ncnn-YYYYMMDD-full-source.zip" 下载
|
||||
- 或用 git 获取最新版本：
|
||||
|
||||
```batch
|
||||
git clone https://github.com/tencent/ncnn
|
||||
git submodule update --init
|
||||
```
|
||||
|
||||
#### 编译安装 ncnn
|
||||
```batch
|
||||
mkdir build-vs2019
|
||||
cd build-vs2019
|
||||
cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_INSTALL_PREFIX="%cd%/install" -DNCNN_VULKAN=ON
|
||||
cmake --build . --config Release
|
||||
cmake --install . --config Release
|
||||
cmake --build . --config Debug
|
||||
cmake --install . --config Debug
|
||||
```
|
||||
|
||||
### 编译安装 ncnn 库和模型转换工具
|
||||
|
||||
- 此步骤用于编译模型转换工具，可跳过，直接使用 https://convertmodel.com 工具转换
|
||||
|
||||
- 以下命令行均使用 **适用于 VS 2019 的 x64 本机工具命令提示**
|
||||
|
||||
*注：若在 cmd / PowerShell 进行，需修改：*
|
||||
- `-G"NMake Makefile"` 改为合适的 Generator 如 `-G "Visual Studio 16 2019" -A x64`
|
||||
- `nmake` 改为 `cmake --build . --config Release`， 或打开 `.sln` 手动触发 `protobuf` / `ncnn` 项的构建
|
||||
- `nmake install` 改为 `cmake --install . --config Release`，或打开 `.sln` 手动触发 `INSTALL` 项的构建
|
||||
|
||||
|
||||
#### 编译安装 protobuf
|
||||
|
||||
用于生成 caffe2ncnn 和 onnx2ncnn 工具
|
||||
|
||||
https://github.com/google/protobuf/archive/v3.4.0.zip
|
||||
|
||||
我下载到 C:/Users/shuiz/source 解压缩
|
||||
|
||||
```batch
|
||||
mkdir build-vs2019
|
||||
cd build-vs2019
|
||||
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="%cd%/install" ^
|
||||
-Dprotobuf_BUILD_TESTS=OFF ^
|
||||
-Dprotobuf_MSVC_STATIC_RUNTIME=OFF ../cmake
|
||||
nmake
|
||||
nmake install
|
||||
```
|
||||
|
||||
protobuf 会安装在 build-vs2019/install 里头
|
||||
|
||||
#### 编译安装 ncnn
|
||||
|
||||
https://github.com/Tencent/ncnn.git
|
||||
|
||||
cmake 命令中的 protobuf 路径要相应修改成自己的
|
||||
|
||||
```batch
|
||||
mkdir build-vs2019
|
||||
cd build-vs2019
|
||||
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="%cd%/install" ^
|
||||
-DProtobuf_INCLUDE_DIR=C:/Users/shuiz/source/protobuf-3.4.0/build-vs2019/install/include ^
|
||||
-DProtobuf_LIBRARIES=C:/Users/shuiz/source/protobuf-3.4.0/build-vs2019/install/lib/libprotobuf.lib ^
|
||||
-DProtobuf_PROTOC_EXECUTABLE=C:/Users/shuiz/source/protobuf-3.4.0/build-vs2019/install/bin/protoc.exe ..
|
||||
nmake
|
||||
nmake install
|
||||
```
|
||||
|
||||
ncnn 会安装在 build-vs2019/install 里头
|
||||
|
||||
ncnn 转换工具在 build-vs2019/tools 里头
|
||||
|
||||
#### mlir2ncnn
|
||||
|
||||
见 [build-mlir2ncnn](build-mlir2ncnn.md)
|
||||
|
||||
## 使用编译好的 ncnn 库
|
||||
|
||||
CMakeLists 里写
|
||||
```cmake
|
||||
set(ncnn_DIR "C:/Users/shuiz/source/ncnn/build-vs2019/install/lib/cmake/ncnn" CACHE PATH "包含 ncnnConfig.cmake 的目录")
|
||||
find_package(ncnn REQUIRED)
|
||||
target_link_libraries(my_target ncnn)
|
||||
```

||||
### Build for Linux
|
||||
|
||||
Install required build dependencies:
|
||||
|
||||
* git
|
||||
* g++
|
||||
* cmake
|
||||
* protocol buffer (protobuf) headers files and protobuf compiler
|
||||
* vulkan header files and loader library
|
||||
* glslang
|
||||
* (optional) opencv # For building examples
|
||||
|
||||
Generally if you have Intel, AMD or Nvidia GPU from last 10 years, Vulkan can be easily used.
|
||||
|
||||
On some systems there are no Vulkan drivers easily available at the moment (October 2020), so you might need to disable use of Vulkan on them. This applies to Raspberry Pi 3 (but there is experimental open source Vulkan driver in the works, which is not ready yet). Nvidia Tegra series devices (like Nvidia Jetson) should support Vulkan. Ensure you have most recent software installed for best experience.
|
||||
|
||||
On Debian, Ubuntu or Raspberry Pi OS, you can install all required dependencies using:
|
||||
```shell
|
||||
sudo apt install build-essential git cmake libprotobuf-dev protobuf-compiler libvulkan-dev vulkan-utils libopencv-dev
|
||||
```
|
||||
To use Vulkan backend install Vulkan header files, a vulkan driver loader, GLSL to SPIR-V compiler and vulkaninfo tool. Preferably from your distribution repositories. Alternatively download and install full Vulkan SDK (about 200MB in size; it contains all header files, documentation and prebuilt loader, as well some extra tools and source code of everything) from https://vulkan.lunarg.com/sdk/home
|
||||
|
||||
```shell
|
||||
wget https://sdk.lunarg.com/sdk/download/1.2.189.0/linux/vulkansdk-linux-x86_64-1.2.189.0.tar.gz?Human=true -O vulkansdk-linux-x86_64-1.2.189.0.tar.gz
|
||||
tar -xf vulkansdk-linux-x86_64-1.2.189.0.tar.gz
|
||||
export VULKAN_SDK=$(pwd)/1.2.189.0/x86_64
|
||||
```
|
||||
|
||||
To use Vulkan after building ncnn later, you will also need to have Vulkan driver for your GPU. For AMD and Intel GPUs these can be found in Mesa graphics driver, which usually is installed by default on all distros (i.e. `sudo apt install mesa-vulkan-drivers` on Debian/Ubuntu). For Nvidia GPUs the proprietary Nvidia driver must be downloaded and installed (some distros will allow easier installation in some way). After installing Vulkan driver, confirm Vulkan libraries and driver are working, by using `vulkaninfo` or `vulkaninfo | grep deviceType`, it should list GPU device type. If there are more than one GPU installed (including the case of integrated GPU and discrete GPU, commonly found in laptops), you might need to note the order of devices to use later on.
|
||||
|
||||
#### Nvidia Jetson
|
||||
|
||||
The Vulkan driver is a default component of the Linux For Tegra BSP release, check [the device list](https://developer.nvidia.com/embedded/vulkan).
|
||||
|
||||
```shell
|
||||
cd ncnn
|
||||
mkdir -p build
|
||||
cd build
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=../toolchains/jetson.toolchain.cmake -DNCNN_VULKAN=ON -DNCNN_BUILD_EXAMPLES=ON ..
|
||||
make -j$(nproc)
|
||||
```
|
||||
|
||||
#### Raspberry Pi
|
||||
|
||||
Vulkan drivers do exists, but are not mature. You are free to experiment at your own discretion, and report results and performance.
|
||||
|
||||
```shell
|
||||
cd ncnn
|
||||
mkdir -p build
|
||||
cd build
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DNCNN_VULKAN=ON -DNCNN_SYSTEM_GLSLANG=ON -DNCNN_BUILD_EXAMPLES=ON ..
|
||||
make -j$(nproc)
|
||||
```
|
||||
|
||||
You can add `-GNinja` to `cmake` above to use Ninja build system (invoke build using `ninja` or `cmake --build .`).
|
||||
|
||||
For Rasberry Pi 3, add `-DCMAKE_TOOLCHAIN_FILE=../toolchains/pi3.toolchain.cmake -DPI3=ON` to cmake. You can also consider disabling Vulkan support as the Vulkan drivers for Rasberry Pi are still not mature, but it doesn't hurt to build the support in, but not use it.
|
||||
|
||||
#### Verification
|
||||
|
||||
Verify build by running some examples:
|
||||
|
||||
```shell
|
||||
cd ../examples
|
||||
../build/examples/squeezenet ../images/256-ncnn.png
|
||||
[0 AMD RADV FIJI (LLVM 10.0.1)] queueC=1[4] queueG=0[1] queueT=0[1]
|
||||
[0 AMD RADV FIJI (LLVM 10.0.1)] bugsbn1=0 buglbia=0 bugcopc=0 bugihfa=0
|
||||
[0 AMD RADV FIJI (LLVM 10.0.1)] fp16p=1 fp16s=1 fp16a=0 int8s=1 int8a=1
|
||||
532 = 0.163452
|
||||
920 = 0.093140
|
||||
716 = 0.061584
|
||||
```
|
||||
|
||||
You can also run benchmarks (the 4th argument is a GPU device index to use, refer to `vulkaninfo`, if you have more than one GPU):
|
||||
|
||||
```shell
|
||||
cd ../benchmark
|
||||
../build/benchmark/benchncnn 10 $(nproc) 0 0
|
||||
[0 AMD RADV FIJI (LLVM 10.0.1)] queueC=1[4] queueG=0[1] queueT=0[1]
|
||||

|
||||
[0 AMD RADV FIJI (LLVM 10.0.1)] fp16p=1 fp16s=1 fp16a=0 int8s=1 int8a=1
|
||||
num_threads = 4
|
||||
powersave = 0
|
||||
gpu_device = 0
|
||||
cooling_down = 1
|
||||
squeezenet min = 4.68 max = 4.99 avg = 4.85
|
||||
squeezenet_int8 min = 38.52 max = 66.90 avg = 48.52
|
||||
...
|
||||
```
|
||||
|
||||
To run benchmarks on a CPU, set the 5th argument to `-1`.

Download protobuf-3.4.0 from https://github.com/google/protobuf/archive/v3.4.0.zip
|
||||
|
||||
Build protobuf library:
|
||||
|
||||
```shell
|
||||
cd <protobuf-root-dir>
|
||||
mkdir build
|
||||
cd build
|
||||
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%cd%/install -Dprotobuf_BUILD_TESTS=OFF -Dprotobuf_MSVC_STATIC_RUNTIME=OFF ../cmake
|
||||

|
||||
cd <ncnn-root-dir>
|
||||
mkdir -p build-arm-linux-gnueabi
|
||||
cd build-arm-linux-gnueabi
|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchains/arm-linux-gnueabi.toolchain.cmake ..
|
||||
make -j$(nproc)
|
||||
```
|
||||
|
||||

|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchains/arm-linux-gnueabihf.toolchain.cmake ..
|
||||
make -j$(nproc)
|
||||
```
|
||||
|
||||
AArch64 GNU/Linux target (aarch64-linux-gnu)
|
||||
```shell
|

### Build for Loongson 2K1000
|
||||
|
||||
For gcc version < 8.5, you need to fix msa.h header for workaround msa fmadd/fmsub/maddv/msubv bug.
|
||||
|
||||
Open ```/usr/lib/gcc/mips64el-linux-gnuabi64/8/include/msa.h```, find ```__msa_fmadd``` and ```__msa_fmsub``` and apply changes as the following
|
||||
```c
|
||||
// #define __msa_fmadd_w __builtin_msa_fmadd_w
|
||||
// #define __msa_fmadd_d __builtin_msa_fmadd_d
|
||||
// #define __msa_fmsub_w __builtin_msa_fmsub_w
|
||||
// #define __msa_fmsub_d __builtin_msa_fmsub_d
|
||||
#define __msa_fmadd_w(a, b, c) __builtin_msa_fmadd_w(c, b, a)
|
||||
#define __msa_fmadd_d(a, b, c) __builtin_msa_fmadd_d(c, b, a)
|
||||
#define __msa_fmsub_w(a, b, c) __builtin_msa_fmsub_w(c, b, a)
|
||||
#define __msa_fmsub_d(a, b, c) __builtin_msa_fmsub_d(c, b, a)
|
||||
```
|
||||
|
||||
find ```__msa_maddv``` and ```__msa_msubv``` and apply changes as the following
|
||||
```c
|
||||
// #define __msa_maddv_b __builtin_msa_maddv_b
|
||||
// #define __msa_maddv_h __builtin_msa_maddv_h
|
||||
// #define __msa_maddv_w __builtin_msa_maddv_w
|
||||
// #define __msa_maddv_d __builtin_msa_maddv_d
|
||||
// #define __msa_msubv_b __builtin_msa_msubv_b
|
||||
// #define __msa_msubv_h __builtin_msa_msubv_h
|
||||
// #define __msa_msubv_w __builtin_msa_msubv_w
|
||||
// #define __msa_msubv_d __builtin_msa_msubv_d
|
||||
#define __msa_maddv_b(a, b, c) __builtin_msa_maddv_b(c, b, a)
|
||||
#define __msa_maddv_h(a, b, c) __builtin_msa_maddv_h(c, b, a)
|
||||
#define __msa_maddv_w(a, b, c) __builtin_msa_maddv_w(c, b, a)
|
||||
#define __msa_maddv_d(a, b, c) __builtin_msa_maddv_d(c, b, a)
|
||||
#define __msa_msubv_b(a, b, c) __builtin_msa_msubv_b(c, b, a)
|
||||
#define __msa_msubv_h(a, b, c) __builtin_msa_msubv_h(c, b, a)
|
||||
#define __msa_msubv_w(a, b, c) __builtin_msa_msubv_w(c, b, a)
|
||||
#define __msa_msubv_d(a, b, c) __builtin_msa_msubv_d(c, b, a)
|
||||
```
|
||||
|
||||
Build ncnn with mips msa and simpleocv enabled:
|
||||
```shell
|
||||
mkdir -p build
|
||||
cd build
|
||||
cmake -DNCNN_DISABLE_RTTI=ON -DNCNN_DISABLE_EXCEPTION=ON -DNCNN_RUNTIME_CPU=OFF -DNCNN_MSA=ON -DNCNN_MMI=ON -DNCNN_SIMPLEOCV=ON ..
|
||||
cmake --build . -j 2
|
||||
cmake --build . --target install
|
||||
```
|
||||
|
||||
Pick `build/install` folder for further usage.
|
||||
|
||||
You can run binary inside `build/examples` folder for testing.
|
||||

### Build for Termux on Android
|
||||
|
||||
Install app Termux on your phone,and install Ubuntu in Termux.
|
||||
|
||||
If you want use ssh, just install openssh in Termux
|
||||
|
||||
```
|
||||
pkg install proot-distro
|
||||
proot-distro install ubuntu
|
||||
```
|
||||
|
||||
or you can see what system can be installed using `proot-distro list`
|
||||
|
||||
while you install ubuntu successfully, using `proot-distro login ubuntu` to login Ubuntu.
|
||||
|
||||
Then make ncnn,no need to install any other dependencies.
|
||||
|
||||
```
|
||||
git clone https://github.com/Tencent/ncnn.git
|
||||
cd ncnn
|
||||
git submodule update --init
|
||||
mkdir -p build
|
||||
cd build
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DNCNN_BUILD_EXAMPLES=ON -DNCNN_PLATFORM_API=OFF -DNCNN_SIMPLEOCV=ON ..
|
||||
make -j$(nproc)
|
||||
```
|
||||
|
||||
Then you can run a test
