That is strange. According to https://learn.microsoft.com/en-us/windows/win32/winprog/windows-data-types#ssize_t , `SSIZE_T` should be available after including basetsd.h Which compiler do you use to compile mycamera.cpp? Also Visual Studio 2019? You mentioned something about...

Maybe search your computer for `basetsd.h` and check whether `SSIZE_T` is defined in there?

I also did some tests and yes, it looks like an alignment problem. The first and last pointers of the `points` vector (which mark the used range) were both 0,...

I just tested with the PCL 1.14.0 all-in-one installer, and it works. So the error _only_ happens with the PCL 1.13.1 all-in-one installer. Other PCL versions work with the all-in-one...
