issue:
issue1:
gflags
gflags是使用源码安装,因此解决方法是:
进入gflags/build中,找到CMakeCache.txt
改为CMAKE_CXX_FLAGS:STRING=-fPIC
再执行就可以
export CXXFLAGS="-fPIC" && cmake .. && make VERBOSE=1
make && make install
if not install gflags as above, make -j8 for rocksdb will throw below error:
/usr/bin/ld: /usr/local/lib/libgflags.a(gflags.cc.o):relocation R_X86_64_32S against
issue2:
make rocksdb will happen pthread issue, need to add -pthread for link. the example pls check CMakeLists.txt in this directory.
