In sip/gencode.c(line 5954) is this code in prcode(FILe *fp, char *fmt, ...) switch (ch) { case 'c': { char c = va_arg(ap,char); if (c == '\n') ++currentLineNr; that works on a little endian machine (x86) as the compiler actually passes the parameter in the low order byte of an int which is the first byte. On a big endian machine (sparc) the compiler also passes it in the low order byte of an int but that is the fourth byte and the above code grabs the first byte. The result was files generated by sip at a bunch of NUL ('\0') characters. Change it to char c = va_arg(ap,int); and everything works. --pete
