LYRIC comes with a header file named Defines.hpp, which defines some usefull stuff. To stick to C++’s philosophy only a minimum amount of things have been defined.
A special note for Microsoft Visual Studio users: Visual Studio sets debug information generation to Generate Debug Information Database for Edit and Continue as default for Debug targets. This option makes that the standard macro __LINE__ is no longer a macro but some strange variable. In this mode of debug information generation LYRIC_HERE will not give the expected output for line numbers. The trick is to set debug information generation to Generate Debug Information Database. This is a Visual Studio bug, not a wrong definition of the LYRIC_HERE macro, which respects Microsoft’s documentation1 about the preprocessor and standard macros.
