检查下你的环境里面是不是有多个不同版本的gflags

[kevinmgyu]

没有呀，只有一个gflags

只安装了一个，符号表如上边

[zyearn]

看起来是linker没有找到gflags，用cmake的话，看下CMakeCache.txt里面GFLAGS_LIBRARY=是不是正确找到了。如果都设置了，试一下mkdir build; cmake ..; make VERBOSE=1; 在链接的时候看下gflags有没有被加上去

[kevinmgyu]

我apt-get移除了所有安装，然后收到安装到了/user/local/lib目录下，然后用上边说的cmake方式编译， /usr/bin/ld: /usr/local/lib/libgflags.a(gflags.cc.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC

[kevinmgyu]

手动安装到了/user/local/lib目录下

[kevinmgyu]

忽略吧，谢谢各位，问题已经解决

[chenyinjing]

求问怎么解决的？我也遇到了

[flily]

这个问题我解决了，gflags和protobuf编译的时候没有-fPIC参数，最后链接的时候出的问题。这两个的源代码我自己重新编译了一次，在CMakeFiles.txt的最后加上一行set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC")。

看起来似乎编译动态库的时候也会有其他问题，所以还是都编译成静态库，做静态链接比较稳妥。 protobuf的cmake参数加上-Dprotobuf_BUILD_SHARED_LIBS=OFF。 gflags的cmake参数加上-DBUILD_SHARED_LIBS=OFF。

参考环境：Ubuntu 18.04.2 LTS，gcc/g++ 7.4.0，gflags 2.2.2，protobuf 3.2.1

[jjahg520]

我也遇到一模一样的问题了 怎么解决的？

[chenyinjing]

换一下protonbuf版本，重新编译一下。

ABI问题，编译gflags时可以在cmakelists 中添加 add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0) 解决
