从源码编译
----------
用户也可以从 PaddlePaddle 核心代码编译C++预测库,只需在编译时配制下面这些编译选项:
================= =========
选项 值
================= =========
CMAKE_BUILD_TYPE Release
FLUID_INSTALL_DIR 安装路径
WITH_FLUID_ONLY ON推荐
WITH_SWIG_PY OFF推荐
WITH_PYTHON OFF推荐
WITH_GPU ON/OFF
WITH_MKL ON/OFF
================= =========
建议按照推荐值设置,以避免链接不必要的库。其它可选编译选项按需进行设定。
下面的代码片段从github拉取最新代码配制编译选项需要将PADDLE_ROOT替换为PaddlePaddle预测库的安装路径
.. code-block:: bash
pip install paddlepaddle-gpu
PADDLE_ROOT=/path/of/capi
git clone https://github.com/PaddlePaddle/Paddle.git
cd Paddle
mkdir build
cd build
cmake -DFLUID_INSTALL_DIR=$PADDLE_ROOT \
-DCMAKE_BUILD_TYPE=Release \
-DWITH_FLUID_ONLY=ON \
-DWITH_SWIG_PY=OFF \
-DWITH_PYTHON=OFF \
-DWITH_MKL=OFF \
-DWITH_GPU=OFF \
..
make
make inference_lib_dist
成功编译后使用C++预测库所需的依赖包括1编译出的PaddlePaddle预测库和头文件2第三方链接库和头文件3版本信息与编译选项信息
均会存放于PADDLE_ROOT目录中。目录结构如下
