Run flex like this:
|
|
|
|
flex --prefix=cmExpr_yy --header-file=cmExprLexer.h -ocmExprLexer.cxx cmExprLexer.in.l
|
|
|
|
Modify cmExprLexer.cxx:
|
|
- remove TABs
|
|
- remove "yyscanner" argument from these methods:
|
|
yy_fatal_error, cmExpr_yyalloc, cmExpr_yyrealloc, cmExpr_yyfree
|
|
- remove all YY_BREAK lines occurring right after return statements
|
|
- change while ( 1 ) to for(;;)
|
|
|
|
Modify cmExprLexer.h:
|
|
- remove TABs
|
|
- remove the yy_init_globals function
|
|
- remove the block that includes unistd.h
|
|
- remove #line directives (avoids bogus warning on old Sun)
