Strange problem trying to compile tcpd

Strange problem trying to compile tcpd

[Prentis Brooks]

-----BEGIN PGP SIGNED MESSAGE-----

I made the following change to the Makefile

#######################################
# Cygwin make
cygwin:
        @make REAL_DAEMON_DIR=$(REAL_DAEMON_DIR) STYLE=$(STYLE) \
        LIBS= RANLIB=ranlib ARFLAGS=rv \
        AUX_OBJ=setenv.o \
        NETGROUP= TLI= EXTRA_CFLAGS="-DBROKEN_SO_LINGER" all

########################################

extrapolating as best as I can from the other templates.  I also set
the system to use the following REAL_DAEMON_DIR=/contrib/libexec

NOTE: Cygwin was installed to C:\

The following is where the make breaks:
################################

You'll have to add a `#include <errno.h>' to percnt_m.c.

Ok... that is not it... percent_m.c does include <errno.h>

I have a feeling that for some reason the error is occurring in the
library.  The real frustrating part is that I got this work on b20,
but inadvertently deleted my source in a system rebuild.  Anyone got
any other ideas?

Did you search for extern declarations of sys_nerr and sys_errlist?
Some programs do a

	extern int sys_nerr;
	extern char *sys_errlist[]

which is wrong for Cygwin.

You'll have to do sth like that:

#ifdef __CYGWIN__
#  define sys_nerr _sys_nerr
#  define sys_errlist _sys_errlist
#else
   extern int sys_nerr;
   extern char *sys_errlist[]
#endif

Cool... percent_m.c does use an extern call, I will try that...

btw, does someone have a working inetd.conf that I can look at?  one
does not ship on the CD and my only other refs are Solaris :)

The format is the same. If you're using the inetutils port you
need not using tcpd but call the deamons immediatly:

Instead of

ftp     stream  tcp     nowait  root    /usr/sbin/tcpd  in.ftpd

use

ftp     stream  tcp     nowait  root    /usr/local/libexec/in.ftpd

Thanks, I just got inetd working with tcpd... btw, is there somewhere
I can send my source for others to use, I noticed that it does not
exist in any of the archives that I looked through.

Ask Michael Hirmke ( mailto:mh@mike.franken.de ). He masters
the cygwin mirror and porters directories on ftp.franken.de.

I would be glad if you could send me your tcpd port as tar.gz file.
Is this possible?

I am interested.
