Part of the issue is that upstream jpeglib.h is not designed to compile under C++. It is not entirely clear to me that it is the responsibility of /usr/include/jpeglib.h to #include <stdio.h> rather than the responsibility of WebKit. Actually since C programs have to #include <stdio.h>, it seems that WebKit should do it as well, and g++-4.3 is exhibiting a latent bug in WebKit. The libjpeg documentation says that: /* * Include file for users of JPEG library. * You will need to have included system headers that define at least * the typedefs FILE and size_t before you can include jpeglib.h. * (stdio.h is sufficient on ANSI-conforming systems.) * You may also wish to include "jerror.h". */ Cheers, -- Bill. <[EMAIL PROTECTED]> Imagine a large red swirl here. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
