/Users/snow/Desktop/idp-src/src/utils/MemoryUsage.cpp: In function 'size_t getCurrentRSS()': /Users/snow/Desktop/idp-src/src/utils/MemoryUsage.cpp:89:30: error: aggregate 'getCurrentRSS()::mach_task_basic_info info' has incomplete type and cannot be defined /Users/snow/Desktop/idp-src/src/utils/MemoryUsage.cpp:122:1: warning: control reaches end of non-void function [-Wreturn-type] make[2]: *** [src/CMakeFiles/idp.dir/utils/MemoryUsage.cpp.o] Error 1
