Cmake4编译PaddleOCR3.0成功步骤

news 来源：原创 2025/5/29 8:10:51

编译相关软件： Cmake4.0+VS2022+PaddleOCR3.0

下载地址：

PaddleOCR发布版本3.0下载地址
https://github.com/PaddlePaddle/PaddleOCR/tree/release/3.0

PaddleOCR推理库3.0下载地址
https://paddle-inference-lib.bj.bcebos.com/3.0.0/cxx_c/Windows/CPU/x86-64_avx-mkl-vs2019/paddle_inference.zip

一、打开Cmake软件，配置PaddleOCR3.0编译相关参数如下：

源码目录：D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer

生成目录：D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\build_vs2019_x64

二、点击【Configure】按钮，设置详细配置参数如下：

CMAKE_INSTALL_PREFIX设置安装路径为:D:/PaddleOCR30/PaddleOCR-release-3.0/deploy/cpp_infer/build_vs2019_x64/install

OPENCV_DIR设置为本地的Opencv目录：D:/opencv410/build_vs2019_x64/install/x64/vc16/lib

OpenCV_DIR目录设置同上：D:/opencv410/build_vs2019_x64/install/x64/vc16/lib

PADDLE_LIB目录设置为：D:/PaddleOCR30/paddle_inference3.0

WITH_GPU选项设置为：不勾选
WITH_MKL选项设置为：勾选
WITH_STATIC_LIB选项设置为：勾选
WITH_TENSORRT选项设置为：不勾选

三、异常错误处理办法如下：

3.1错误一： Failed to clone repository: 'https://github.com/LDOUBLEV/AutoLog.git'
external-cmake/auto-log.cmake:13 (FetchContent_MakeAvailable)
CMakeLists.txt:220 (include)

解决办法：修改D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\external-cmake\auto-log.cmake文件内容如下：

find_package(Git REQUIRED)
include(FetchContent)set(FETCHCONTENT_BASE_DIR "${CMAKE_CURRENT_BINARY_DIR}/third-party")FetchContent_Declare(extern_AutologPREFIX autolog# If you don't have access to github, replace it with https://gitee.com/Double_V/AutoLogGIT_REPOSITORY https://gitee.com/Double_V/AutoLogGIT_TAG        main
)
FetchContent_MakeAvailable(extern_Autolog)

3.2错误二：D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\build_vs2019_x64\third-party\extern_autolog-src\CMakeLists.txt文件错误，需要修改VERSION3.5到4.0

cmake_minimum_required(VERSION 4.0)
project(cpp_auto_log CXX C)message("default cmake for auto_log, no need to compile")

四、点击【Generate】按钮生成VS项目解决方案文件：D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\build_vs2019_x64\ppocr.sln。点击【Open Project】按钮,系统自动在VS202软件中打开对应的解决方案。

在VS202软件中选则编译模式为Release+64位，鼠标右键点击解决方案名称，选择【重新生成解决方案】，系统报错,主要解决方法包含如下三点：

4.1需要下载头文件https://github.com/tronkko/dirent/blob/master/include/dirent.h，拷贝到
D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\include目录下，并修改D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\src\utility.cpp文件中引用路径为#include <include/dirent.h>

4.2删除D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\build_vs2019_x64\third-party\extern_autolog-src\auto_log\autolog.h文件中的报错代码

4.3参考上文Cmake编译yaml-cpp并在QT中测试成功操作步骤-CSDN博客手动编译和拷贝yaml-cpp对应的静态库文件D:\yaml-cpp-master\build_vs2022\Release\yaml-cpp.lib到D:\PaddleOCR30\paddle_inference3.0\third_party\install\yaml-cpp\lib\yaml-cpp.lib

4.4拷贝D:\PaddleOCR30\paddle_inference3.0\paddle\lib\common.dll和D:\PaddleOCR30\paddle_inference3.0\paddle\lib\paddle_inference.dll两个文件到运行目录D:\PaddleOCR30\PaddleOCR-release-3.0\deploy\cpp_infer\build_vs2019_x64\Release下

4.5拷贝本地的opencv对应的dll文件(D:\opencv410\build_vs2019_x64\install\x64\vc16\bin\opencv_world4100.dll)到对应目录（D:\PaddleOCR\build_vs2019_x64\Release）下

4.6修改Source Files目录下的args.cpp文件中的配置项如下：

修改后的args.cpp全文内容如下：


#include <gflags/gflags.h>// common args
DEFINE_bool(use_gpu, false, "Inferring with GPU or CPU.");
DEFINE_bool(use_tensorrt, false, "Whether use tensorrt.");

DEFINE_double(det_db_box_thresh, 0.6, "Threshold of det_db_box_thresh.");

DEFINE_int32(rec_batch_num, 6, "rec_batch_num.");
DEFINE_string(rec_char_dict_path, "D:/PaddleOCR30/PaddleOCR-release-3.0/ppocr/utils/ppocr_keys_v1.txt",              "Path of dictionary.");
DEFINE_int32(rec_img_h, 48, "rec image height");
DEFINE_int32(rec_img_w, 320, "rec image width");// layout model related
DEFINE_string(layout_model_dir, "", "Path of table layout inference model.");
DEFINE_string(layout_dict_path,"D:/PaddleOCR30/PaddleOCR-release-3.0/ppocr/utils/dict/layout_dict/layout_publaynet_dict.txt","Path of dictionary.");
DEFINE_double(layout_score_threshold, 0.5, "Threshold of score.");
DEFINE_double(layout_nms_threshold, 0.5, "Threshold of nms.");
// structure model related
DEFINE_string(table_model_dir, "", "Path of table structure inference model.");
DEFINE_int32(table_max_len, 488, "max len size of input image.");
DEFINE_int32(table_batch_num, 1, "table_batch_num.");
DEFINE_bool(merge_no_span_structure, true,"Whether merge <td> and </td> to <td></td>");
DEFINE_string(table_char_dict_path, "D:/PaddleOCR30/PaddleOCR-release-3.0/ppocr/utils/dict/table_structure_dict_ch.txt","Path of dictionary.");// ocr forward related
DEFINE_bool(det, true, "Whether use det in forward.");
DEFINE_bool(rec, true, "Whether use rec in forward.");
DEFINE_bool(cls, false, "Whether use cls in forward.");
DEFINE_bool(table, false, "Whether use table structure in forward.");
DEFINE_bool(layout, false, "Whether use layout analysis in forward.");

五、运行项目

使用Notepad--软件修改D:\PaddleOCR30\PaddleOCR-release-3.0\ppocr\utils\ppocr_keys_v1.txt文本文件编码为ANSI/GBK后再运行就没有乱码了。
