1.定义protobuf
package ImageRender;
message MessagePadding
{
required int32 left = 1;
required int32 top = 2;
required int32 right = 3;
required int32 bottom = 4;
}
2.通过protoc.exe编译proto文件
一般可以写一个bat来执行命令:
%~d0
cd %~p0
rem The following adds the paths of both tf.exe and MsBuild.exe.
set PATH="E:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\cmd";C:\Windows\Microsoft.NET\Framework\v4.0.30319;%PATH%
rem generate cpp code
"./protoc.exe" --proto_path =./ --cpp_out=../ProtoInclude ./xxxxx.proto
pause
错误解决
-
找不到生成的.h头文件
#设置pb生成的文件目录
set(PROJECT_PROTO_DIR ${PROJECT_SOURCE_DIR}/ProtoInclude)
message(STATUS "PROJECT_PROTO_DIR is ${PROJECT_PROTO_DIR}")#定义头文件需要寻址的路径
include_directories(
XXXXX
${PROJECT_PROTO_DIR}
XXXXX
) -
编译过程中出现LINK2019的问题:
解决:
需要加入依赖的lib【libprotobuf64与libprotobuf-lite】,并把自动生成的cc文件引入到项目。
set(PB_CC_FILES
${PROJECT_SOURCE_DIR}/ProtoInclude/xxxxx.pb.cc
)
#把目录src和inc下面的所有文件作为变量存储
file(GLOB_RECURSE SRC_FILES "src/*")
file(GLOB_RECURSE INC_FILES "include/*")
add_executable(DemoApp1 ${SRC_FILES} ${INC_FILES} ${PB_CC_FILES})
target_link_libraries(DemoApp1
XXXXX
libprotobuf64
libprotobuf-lite
)
