When building the Unreal Engine 4.23 source, some of the pathnames are really, really, long, like:
this is 209 characters just by itself. If you have some prefix path in front of that, it can easily exceed 260 characters. On some people’s machines, this is causing a build failure.
3>LINK : fatal error LNK1104: cannot open file ‘E:\xxxxxxxxxSecondary\depot\xx\New\Dev\UnrealEngine\Engine\Plugins\Developer\Concert\ConcertSync\ConcertSyncServer\Intermediate\Build\Win64\UnrealDisasterRecoveryService\Development\ConcertSyncServer\UnrealDisasterRecoveryService-ConcertSyncServer.dll.response’
I am not sure under what circumstances 260 characters is still a limit in Windows. Does Epic recommend really short paths that prefix engine pathnames?
