C++ 4.19 Transition Guide

[anonymous_user_8174d520]

In case anyone else has isssues with GPU stats not working any more after transitioning from 4.18 to 4.19, here’s a fix.

I got the following compiler errors after upgrading to 4.19:

Error C2660 ‘FScopedGPUStatEvent::Begin’: function does not take 1 arguments
Error C2065 ‘_GCsvStat_Stat_GPU_MyFunctionToProfile’: undeclared identifier
Error C2228 left of ‘.Name’ must have class/struct/union
Error C2065 ‘StatPtr_Stat_GPU_Stat_GPU_MyFunctionToProfile’: undeclared identifier
Error C2228 left of ‘.GetStatId’ must have class/struct/union
Error C2228 left of ‘.GetName’ must have class/struct/union

I fixed this by changing my stat declaration macros from

DECLARE_FLOAT_COUNTER_STAT(TEXT("MyFunctionToProfile"), Stat_GPU_MyFunctionToProfile, STATGROUP_GPU);

to

DECLARE_FLOAT_COUNTER_STAT(Stat_GPU_MyFunctionToProfile, TEXT("MyFunctionToProfile"));

Best regards!
