My question is similar to this question. However, in this case I can't find any copy of psapi.a or psapi.lib in my \MingGW64\lib folder although psapi.h does exist in \MingGW64\x86_64-w64-mingw32\include.
The error code is undefined reference to `GetProcessMemoryInfo'.
My OS is Windows 10 and g++ version is 4.9.2. The compiling command was g++ std=c++11 -Wall -DPSAPI_VERSION=1 -D LOCAL *.cpp -o *
