The default buffer size is at least 8188 bytes. This option serves to eliminate ``Macro param too large'', ``Macro invocation too large'', ``Macro param too large after substitution'', ``Quoted macro param too large'', ``Macro buffer too small'', ``Input line too long'', and ``Catenated input line too long'' errors.<BR /><BR />But my question is how to modify the -Hnnn into cpp command line because my makefile is sth like this<BR /><BR />CPP = cc -E <BR /><BR />Thanks in advance<BR /><BR /></FILENAME></FILENAME> Tue, 11 Dec 2001 22:37:39 GMT https://community.hpe.com/t5/operating-system-hp-ux/cpp-error/m-p/2629847#M726330 Jay_13 2001-12-11T22:37:39Z https://community.hpe.com/t5/operating-system-hp-ux/cpp-error/m-p/2629848#M726331 For gcc and i think also for cc use can use the option<BR /><BR />-Wp,Hnn<BR /><BR />This tells the cc to pass the option Hnn to the preprocessor.
