关于grpc-c的示例代码地址 https://github.com/lixiangyun/grpc-c.git ，该项目采用gRPC v1.17.2 .
-
若需同官方保持更新，可索引到github地址，其中core目录为C项目。
故障排查罗列
本文采用CentOS系统,其中grpc-c趟坑过程记录如下
- 安装依赖项

#ubuntu系统 apt install -y autoconf automake libtool curl make cmake g++ unzip zlib1g-dev \ zlib1g openssl libssl-dev pkg-config libgflags-dev libgtest-dev #centos系统 yum install -y autoconf automake libtool curl make cmake unzip openssl gcc-c++ \ openssl-devel gflags-devel gtest gtest-devel zlib-devel zlib #pcre-devel zlib zlib-devel openssl openssl-devel #如果独立安装protobuf,该官方提供的版本为2.5.0。在该项目不使用 #yum install -y protobuf protobuf-devel |
- 找不到库openssl 或zlib
No package 'zlib' found
Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing openssl.pc' to the PKG_CONFIG_PATH environment variable No package 'openssl' found Package openssl was not found in the pkg-config search path. Perhaps you should add the directory containingopenssl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'openssl' found
Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing openssl.pc' to the PKG_CONFIG_PATH environment variable No package 'openssl' found Package zlib was not found in the pkg-config search path. Perhaps you should add the directory containingzlib.pc'
to the PKG_CONFIG_PATH environment variable
No package 'zlib' foun

find / -name openssl.pc find / -name zlib.pc #export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:/usr/lib64/pkgconfig #PKG_CONFIG_PATH路径需要配置为包含文件libprotobuf-c.pc的绝对路径 export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:$PKG_CONFIG_PATH #export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:/usr/lib64/pkgconfig:$PKG_CONFIG_PATH |
- 找不到XXX.so

#报错如下 protoc: error while loading shared libraries: libprotobuf.so.17: cannot open shared object file: No such file or directory #解决方法 //找不到XXX.so, 通过find命令找到文件位置，并加入ld索引目录中 echo "/usr/local/lib" >> /etc/ld.so.conf #echo "/usr/local/lib64" >> /etc/ld.so.conf ldconfig |
- 重新编译如果无法找到文件
//zconf.h missing when building with make
make clean
- 编译测试文件时链接错误
//usr/local/lib/libgrpc-c.so：对‘grpc_call_unref’未定义的引用
collect2: 错误：ld 返回 1
make[2]: [foo/foo_bin] 错误 1
make[1]: [foo/CMakeFiles/foo_bin.dir/all] 错误 2
make: [all] 错误 2
[ 16%] Linking C executable foo_bin
//usr/local/lib/libgrpc-c.so：对‘grpc_call_unref’未定义的引用
collect2: 错误：ld 返回 1
make[2]: [foo/foo_bin] 错误 1
make[1]: [foo/CMakeFiles/foo_bin.dir/all] 错误 2
make: [all] 错误 2
搜索该文件，grpc已经在另一个位置安装有，即/usr/lib以及/usr/local/lib都有该动态链接库，以及相应的.h文件在以上两个目录的include目录中，删除重复的。重新编译，即可解决问题。
Build
|
1 2 3 4 5 |
git clone https://github.com/lixiangyun/grpc-c.git cd grpc-c ./builddeps.sh ./buildlib.sh ./buildcmp.sh |
If you want to install dependencies in a different directory other than /usr/local/, use ./builddeps.sh and ./buildlib.sh
Examples
|
1 2 |
cd examples ./build.sh |
To run example code:
|

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH cd examples ./bin/foo_bin server ./bin/foo_bin client |
