Description conrad 2000-02-28 05:46:59 UTC 
libjpeg.so doesn't want to link with C++ programs (as compiled with egcs
1.1.2), unless the following is added to /usr/include/jpeglib.h (from
libjpeg-devel):

(+ are the additions)

#include "jmorecfg.h"		/* seldom changed options */

+ #ifdef __cplusplus
+ extern "C" {
+ #endif

/* Version ID for the JPEG library.

(..skip to bottom of file..)

#include "jerror.h"		/* fetch error codes too */
#endif

+ #ifdef __cplusplus
+ }
+ #endif

#endif /* JPEGLIB_H */

Technically, it's not a bug because you're supposed to do
extern "C" {
#include <jpeglib.h>
}

in C++ programs using libjpeg - but it can't hurt, so I've added the patch in
Rawhide.
