For example, to create a 32-bit release build on a 64-bit Linux machine, do this: mkdir bld cd bld cmake .. The CMake program provides a great deal of control over how you configure a MySQL source distribution. Typically, you do this using options ...
https://dev.mysql.com/spatial-function-argument-handling.html
If a larger value is given, only the lower 32 bits are used. Spatial functions that take multiple geometry arguments require those arguments to have the same SRID value (that is, same value in the lower 32 bits). Spatial values, or geometries, have ...
