This file must be translated to C and modified to build everywhere.
|
|
|
|
Run flex like this:
|
|
|
|
flex --prefix=cmDependsJava_yy --header-file=cmDependsJavaLexer.h -ocmDependsJavaLexer.cxx cmDependsJavaLexer.in.l
|
|
|
|
Modify cmDependsJavaLexer.c:
|
|
- remove TABs
|
|
- remove use of the 'register' storage class specifier
|
|
- remove "yyscanner" argument from these methods:
|
|
yy_fatal_error, cmDependsJava_yyalloc, cmDependsJava_yyrealloc, cmDependsJava_yyfree
|
|
- remove all YY_BREAK lines occurring right after return statements
|
|
- change while ( 1 ) to for(;;)
|
|
|
|
Modify cmDependsJavaLexer.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)
