flexfax: problems compiling HylaFAX on HP-UX 9.07

[Steven A DuChene <sad@hpuerca.atl.hp.com>]

trying to compile Hylafax 4.0 pl2 with gcc on HP-UX 9.07 and I keep getting
the following error:

/usr/local/bin/gcc -I/usr/local/include -D__ANSI_CPP__ -I. -I.. -I/usr/local/include -I../regex -g -O -x c++ -c Dispatcher.c++
Dispatcher.c++: In method `int Dispatcher::waitFor(class FdMask &, class FdMask &, class FdMask &, struct timeval *)':
Dispatcher.c++:628: passing `FdMask *' as argument 2 of `select(size_t, int *, int *, int *, const timeval *)'
Dispatcher.c++: In method `void Dispatcher::checkConnections()':
Dispatcher.c++:750: passing `FdMask *' as argument 2 of `select(size_t, int *, int *, int *, const timeval *)'

In efforts to solve the problem:
I have tried this with both gcc 2.7.2.3 and egcs 1.1.1
I have installed binutils 2.9.1

The code compiled fine on HP-UX 10.20 with gcc 2.8.1 but I need to get the
client software installed on some HP-UX 9.X systems.

BTW, while running the configure script on 9.X it defines CONFIG_BADSELECTPROTO
and this causes a parse error from lines 624 and 747 during a "make depend" and
a "make all" on this same util/Dispatcher.c++ file

The configure script causes the Makefile in port to have syslog.c listed 
on the CFILE line but this causes a problem with LOG_PERROR in syslog.c
which is undefined on HP-UX 9.X and 10.X

I have undefined CONFIG_BADSELECTPROTO in port.h and had port/Makefile 
use vsyslog.c instead of syslog.c to even get this far.
Also I have to enter two lines in port.h so I don't get errors about speed_t
and struct termios being undefined.

#define _TERMIOS_INCLUDED 1
#include <sys/termio.h>

Once this is done in port.h then the following lines can be commented out too:

/*extern int cfsetispeed(const struct termios*, speed_t);*/
/*extern int tcgetattr(int, struct termios*);*/
/*extern int tcsetattr(int, int, const struct termios*);*/
/*extern int tcsendbreak(int, int);*/
/*extern int tcdrain(int);*/
/*extern int tcflush(int, int);*/
/*extern int tcflow(int, int);*/

since all of the above are defined exactly the same in <sys/termio.h>

I compared the port.h and defs files between the 9.07 system and the 10.20
but did not see any other obvious problem causing differences.

Finally a co-worker who knows more about C++ than I do helped me make the
following modifications to util/Dispatcher.c++

628c628
<           nfound = select(_nfds, (int *) &rmaskret, (int *) &wmaskret, (int *) &emaskret, (const timeval *) &howlong);
---
>           nfound = select(_nfds, &rmaskret, &wmaskret, &emaskret, howlong);
750c750
<           if (select(fd+1, (int *) &rmask, NULL, NULL, (const timeval *) &poll) < 0) {
---
>           if (select(fd+1, &rmask, NULL, NULL, &poll) < 0) {

It turns out that the select system call was changed from:

      int select(
           size_t nfds,
           int *readfds,
           int *writefds,
           int *exceptfds,
           const struct timeval *timeout
      );

at 9.X to the following:

int select(int nfds, fd_set *readfds, fd_set *writefds, fd_set
*errorfds, struct timeval *timeout);

at 10.X to make 10.X more compliant.

Now I am getting Unsatisfied symbols symbols when trying to link hfaxd

   FaxRequest type_info function(code)
   FaxRequest type_info node(data)
   vlogError(char const *, double *)(code)

ARGH! Time to go home now. :-(
