To use the ap_[u]int<> classes, you must include the ap_int.h header file in all source files that reference ap_[u]int<> variables.

When compiling software models that use these classes, it may be necessary to specify the location of the Vitis HLS header files, for example by adding the -I/<HLS_HOME>/include option for g++ compilation.
