seems libwx has no clean reference to iconv

anonymous #1 here again. I've been digging into this problem and found out the reason for invalid linkage. The problem lies in iconv.h header file: it's linkage specifiers are valid only for C programs, C++ programs will attempt to link against C++ "decorated" functions which aren't there. wxGTK library, which links to the wrong symbols in this particular case isn't the only one - I've enocountered a few others, but don't remember exactly which ones. The problem was the same.

In order to compile properly, you should modify iconv header in this location


to look like this:

 * Very simple iconv api stub.

#ifndef _ICONV_H
#define _ICONV_H 1

#define _LIBICONV_VERSION 0x010B    /* version number: (major<<8) + minor */

#include <stddef.h>

#ifdef __cplusplus // Added for proper C++ linkage
extern "C" {

extern  int _libiconv_version; /* Likewise */
typedef void *iconv_t;

extern iconv_t
iconv_open(const char *tocode, const char *fromcode);

extern size_t
iconv(iconv_t cd, char **inbuf, size_t *inbytesleft,
                  char **outbuf, size_t *outbytesleft);

extern int
iconv_close(iconv_t cd);

#ifdef __cplusplus

#endif /* _ICONV_H */

Rebuild wxGTK library and aMule should compile fine now. I'm not sure if this place is the most appropriate for this change. I've noticed m4 script in iconv subfolder (which should apparently do what I did by hand), but I have no experience with m4. I'm also new to OpenWrt, so I'll leave this contribution for now as it is and let others more experienced developers decide about the right approach for this problem.
