#define issue

[hgirma]

i am compling a lib on AIX 5.2 using GNU complier and i get the following error:

"lexer.l", line 82.1: 1506-045 (S) Undeclared identifier cfg.

cfg is defined by #define:
#define YY_DECL int cfg_yylex YY_PROTO(( cfg_t *cfg ))

how does this define work?

it 's error when cf is referenced:
[B]cfg->line++;[/B]

[Banfa]

#define YY_DECL int cfg_yylex YY_PROTO(( cfg_t *cfg ))

does not define cfg, it defines YY_DECL

If you do not use YY_DECL then cfg will not be defined. Even if you do use YY_DECL cfg will only be defined in specific circumstances.

We will need to see the code using cfg and and code that uses YY_DECL to be able to fully answer the question.
