Bug ID: 42208
           Summary: Error when compiling winhlp32.
           Product: Wine
           Version: 2.0-rc5
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: programs
          Assignee: [e-mail]

      Distribution: ---

While trying to compile wine with mingw and cygwin as shell, I got this error:

../.././../w/tools/winegcc/winegcc.exe -o winhlp32.exe
-B../.././../w/tools/winebuild --sysroot=../.. -b \

a "yywrap"

It says that "yywrap" is an undefined reference.
This probably happens because the macro.lex.l is not aware of the fact that is
can be also cross compiled, which is the thing you have to do when you want to
run wine natively on Windows, for example.
At the end of the file there is an #ifndef yywrap ... #endif: I replaced it
with an #if 1 and the program has been compiled correctly. But I guess it has
to be fixed correctly.

Sincerely.
