zhouwei-zhcy opened a new issue, #2127:
URL: https://github.com/apache/brpc/issues/2127
在example/echo_c++ 基础上，目标是想把client端编译链接成一个so动态库文件。加上-shared -fPIC 编译选项后，会报错误
gpu.pb.o: relocation R_X86_64_PC32 against symbol
`descriptor_table_gpu_2eproto' can not be used when making a shared object;
recompile with -fPIC
去掉-shared -fPIC可以正常编程出client可执行文件，
烦请专家大佬帮忙看看，是不是哪里配置不对？
