I presently have a compiler to write with Flex and Bison. I have a lex.l file, and a parse.y in which there are no conflicts. I also have a symtable.h included.
I have a makefile as follows... ============================================================ project: parse.tab.o lex.yy.o echo ---> compiling and linking project program cc -DYYDEBUG=1 -o project parse.tab.o lex.yy.o -ly -ll -lm lex.yy.o: lex.yy.c parse.tab.h # the dependencies of lex.yy.o the lexer object echo ---> determining dependency for lex.yy.o lex.yy.o parse.tab.o: symtable.h #just declares that symtable.h is a dependency to both echo ---> determining symtable.h dependency for lex.yy.o parse.tab.o parse.tab.c parse.tab.h: parse.y # THE PARSE C AND H FILES MADE... OK to here echo ---> making parse.tab.c and parse.tab.h bison -d parse.y lex.yy.c : lex.l # THE LEX C FILE MADE echo ---> making lexfile flex lex.l ============================================================ When I run it, I get the following output. The line numbers don't actually correspond. Could you advise as to how the makefile should be written to not have any error? ============================================================ j...@blueacer:/usr/local/project/chk$ make makefile:9: warning: overriding commands for target `lex.yy.o' makefile:6: warning: ignoring old commands for target `lex.yy.o' echo ---> determining symtable.h dependency for lex.yy.o parse.tab.o echo ---> making lexfile flex lex.l echo ---> making parse.tab.c and parse.tab.h bison -d parse.y echo ---> determining symtable.h dependency for lex.yy.o parse.tab.o echo ---> compiling and linking project program cc -DYYDEBUG=1 -o project parse.tab.o lex.yy.o -ly -ll -lm cc: parse.tab.o: No such file or directory cc: lex.yy.o: No such file or directory make: *** [project] Error 1 j...@blueacer:/usr/local/project/chk$ ============================================================ -- View this message in context: http://www.nabble.com/Correct-makefile--for-a-bison-flex-compilation-tp22547478p22547478.html Sent from the Gnu - Bison - Help mailing list archive at Nabble.com. _______________________________________________ help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
