Im getting the following errors when I run 'make' on ubuntu.

The Makefile is not running flex to make the lexer. Try typing

Code: Select all

make objs/lex.yy.o

and see what results you get.

[pgarvey]

running that gives me;

make: `objs/lex.yy.o' is up to date.

[MtnViewJohn]

That's strange. The yyline, yyrestart, and yylex symbols should be defined in lex.yy.o. What happens when you type

Code: Select all

nm objs/lex.yy.o

[pgarvey]

absolutely nothing

[MtnViewJohn]

This is what I get:

[1052] : 

Try deleting objs/lex.yy.* and make objs/lex.yy.o again. The way the Makefile is written it seems to produce objs/lex.yy.o even if the flex operation fails.

[MtnViewJohn]

In the Makefile if you replace the line

Code: Select all

flex -t $^ > $@

with

Code: Select all

flex -o $@ $^

then flex failures will no longer be masked.
