Hi all: I have been in this trouble for a long time:the code need over 7min to buil= d. For example, the last build started in 12:29, and finished in 12:36... the report of build: Memory Summary: =20 Program space used 48A4h ( 18596) of 2FFF8h bytes ( 9.5%) =20 Data space used 294h ( 660) of F40h bytes ( 16.9%) =20 Configuration bits used 2h ( 2) of 3h words ( 66.7%) Well it is a small program. the Compiler is HI-TECH C Compiler for PIC18 MCUs (PRO Mode) V9.80. I don't know why. There are no big arrays in the code. Any informations are welcome!
