在MinGW中安装Protobuf开发库 [英] Installing Protobuf Development Libraries in MinGW

问题描述

我从github上的源代码在MinGW中安装了Protobuf.

I installed Protobuf in MinGW from the sources on github.

当我尝试编译C ++程序时，出现错误:

When I try to compile my C++ program I get errors:

CMakeFiles/nxcore_interface.dir/main.cpp.o:main.cpp:(.rdata$.refptr._ZN6google8protobuf8internal13empty_string_E[.refptr._ZN6google8protobuf8internal13empty_string_E]+0x0): undefined reference to `google::protobuf::internal::empty_string_'
collect2: error: ld returned 1 exit status

我发现了一些指示不存在开发库的东西:

I found something that indicates the development libs are not present:

带有协议缓冲区的程序不要t使用MinGW-w64进行编译:对google :: protobuf :: ...的未定义引用"

我已经包含了-lprotobuf编译器标志.

I have included the -lprotobuf compiler flag.

经过一番搜索，我确定需要使用libprotobuf-dev，但是找不到它.

After some searching I determined I need to use libprotobuf-dev but I am having trouble locating it.

有人知道从哪里获得它，还是有其他问题?

推荐答案

您应使用pkg-config编译应用程序.

You should compile your application with pkg-config.

g++ my_program.cpp `pkg-config --cflags --libs protobuf`

如果没有pkg-config，则应找到库路径并使用-L选项进行设置.例如:

If you don't have pkg-config you should locate libraries path and set them with -L option. Eg:

g++ my_program.cpp -L/usr/local/protobuf/lib -lprotobuf
