解决 Cmake 腾讯云COS SDK 编译失败问题

解决 Cmake 腾讯云COS SDK 编译失败问题

对象存储 COS 的 XML C++ SDK 源码下载地址：

如果用比较漂亮的语言来描述腾讯云cos-cpp-sdk，我觉得可以说是站在巨人肩膀上的健将，结构设计的还是比较漂亮的。 不过仍然存在一些小问题，这里进行一点小小的调整。

uint64_t 不是一个类型名

修复方式

  1. 转到 include/op/cos_result.h 添加头文件<cstdint>或者<stdint.h>

    2
    3
    #include <cstdint>
    #include <map>
    #include <string>

  2. 转到include/util/test_utils.h 添加头文件 <cstdint> 或者 <cstdint.h>

是因为现在的poco库默认已经使用c++14标准库，然而CMakeList.txt中设置仍然是c++11标准，于是修改为C++14

将-std=c11 修改为 -std=c14或者17

其他问题

  1. 如果仍然在编译中出现失败的问题，尝试将编译demo选项关闭
    1
    2
    3
    4
    option(BUILD_UNITTEST "Build unittest" OFF) #配置编译单元测试
    # option(BUILD_DEMO "Build demo" ON) #配置编译 demo 测试代码
    option(BUILD_DEMO "Build demo" OFF) #配置编译 demo 测试代码
    option(BUILD_SHARED_LIB "Build shared library" OFF) #配置编译动态库
  2. POCO链接问题
    1. 尝试将源代码中third_party中poco的库替换和当前系统环境一样的库
    2. 重新编译poco代码
  3. 小甜品
    CMakeLists.txt中的单词还有一个拼错了

个人输出

tmd这个cos sdk真的是依托答辩，用了那么多库，疯狂叠buff, 即使是我使用了vcpkg来配置依赖库仍然麻烦的一批，有一种就是在用poco封装了一层的感觉。里面的详细代码就不评价了。最后奉上我个人测试使用的CMakeLists.txt
