I want to read the Xgboost source code and run the `parameter.cc on mac. this is my command:
cd dmlc-core/example
gcc -std=c++11 -I ../include parameter.cc -o parameter -v
But it throws exceptions ld: symbol(s) not found for architecture x86_64.
Anyone knows how to fix it? Thanks advance!
Below is the stacktrace,due to the question body length limitation, I ommitted some part of the stacktrace.
