Re: [Plib-devel] patch for compiling on Solaris 10

[Fay J. F Dr C. U. AFSEO/SK <joh...@eg...>]

Vikas,

	I have a Windows box and it does not have "sys/socket.h" at all.  I
do not have Cygwin and so have not been able to check that.

	Of note, Windows does not define "socklen_t" at all.

	I think out best bet would be to make the "-Wall" flag
system-dependent.  It is necessary on some systems and creates an error on
other systems, so the most logical step would (in my mind) be to make it
system-dependent.  Do please look into how we do this.

Hi John,

Actually John, the "-Wall" flag is required for the GNU compilers to
show all the warnings. The Sun Studio 11 compilers show all the
warnings by default, and the "-Wall" flag is not accepted. Hence, you
might just need to keep the "-Wall" flag for GNU compilers.

I am not sure about Windows & *BSDs in this regard. socklen_t is
present in Linux and Solaris for sure. If someone has a *BSD or
Windows and can check for the presence of socklen_t in " netinet/in.h"
and  "sys/socket.h" then we can remove it from the configure.in
script. Is plib supported on IRIX too ?
I have an IRIX 6.2 system at home but I am not sure what version of
IRIX you currently support. I can check there for socklen_t.

yes this should be possible. If you want I can look into doing this.
