Problem Statement : Given a C file which has several macros defined (eg. #define MACRO 10) . I need to know what all macros are defined and their usage point(eg. line number) in the code. Need to know this information during or after gcc pre-processing phase. Possible solution may dump this macro information in some file. Is there any way that gcc can dump this information and if yes how? -- View this message in context: http://old.nabble.com/gcc-Pre-Processing-Information-tp31557981p31557981.html Sent from the gcc - Help mailing list archive at Nabble.com.
