cmake protobuf LNK1112 module machine type ‘X86’ conflicts with target machine type ‘x64’

20191211 zhangbin

• 需要cmake 构建visual studio 工程
• 比如grpc，grpc和依赖库都很大
• grpc 依赖于protobuf
• protobuf太大了，不能上传git，所以只能构建了 ，构建只能选cmake

vs2019使用工具链v140

• 构建环境只有vs2015的工具链
• 配置没问题
• -A win32 指定的就是x86 的链接库。
• cmake 构建命令

资料

• 有人说默认是win32，不需要指定，Cmake-gui 确实有这样的情况

• 我现在是cmake 命令行，情况不同。

• 构建grpc ，grpc 官方 不推荐cmake

• protbuf 官方 给出的构建也很简单

fix

• 问题在这里
• 我grpc 1.22.0 的protobuf是3.8.0， 对应cmakelist.txt文件并没改变 ，但是有大神提交了patch
• patch文件
• 这是因为 set(CMAKE_STATIC_LINKER_FLAGS /ignore:4221") 会覆盖 -A Win32指定的machine，
• 改为下面的追加就ok了：

 set(CMAKE_STATIC_LINKER_FLAGS "${CMAKE_STATIC_LINKER_FLAGS} /ignore:4221")
