bcompiler: compile in a diferent directory

I use bcompiler in my php code(bcompiler_write_header+bcompiler_write_file+bcompiler_write_footer). If the original phps are not located in the deployment directory, when I ejecute the compiled code(In deployment directory) I get an error because require_once use the path to the not compiled phps. I'd like to know if there is any way to compile the phps and use the compiled versión from a different directory. Thanks Ramiro
