in reply to Net::Pcap install problem

It's just a guess, but I'd say you don't have a compiler.

What happens if you try typing "cc" at the command line?

(What perl and what platform? I may have better guesses knowing those.)

    This is the C compiler on SUN Solaris 2.8. Path to compiler is /opt/sc6.2a/SUNWspro/bin/cc.

    If I run at command line, I get

    cc -E -I/usr/add-on/exptools/lib/pcap/include -DHAVE_BLANK -DHAVE_PCAP_LIB_VERSION find-funcs.h -o cpp-out.h

    cc: illegal suffix of output filename

    Perl version is 5.005_03, but I tried running it again with perl 5.6.1, and I get the same error message.

      Solaris' system compiler apparently doesn't like -o in combination with -E — at least 

      $ cc -flags | grep -- -E
-E              Compile source through preprocessor only, output to st

      Maybe you could try redirecting the output 

      cc -E  ...  find-funcs.h > cpp-out.h

      Just an idea...

      It isn't perl that's at fault. Personally, I'd hit rt.cpan.org and report that it doesn't compile on solaris. But before I did that, I'd check to see if anyone else reported it. It seems to fail numerous places, but usually older versions.

      http://testers.cpan.org/show/Net-Pcap.html

      It's probably expecting gcc's argument forgiveness, which isn't reasonable with the solaris compiler. It's slightly more picky. My guess is that you could get it to work by farting around with the Build.PL or Makefile.PL, but it might be some work. If you posted that in your ticket... well, then you'd be cooking with fire.

        Thanks all for the tips.

        I'm not sure why Net::Pcap installation would try to use the Solaris cc and not gcc. We have gcc installed on our system, and I have succesfully installed other Perl modules in the past (which used gcc).

        Maybe there is something about Net::Pcap's use of $Config in the Makefile.PL that does not work on Solaris. I noticed that this module has not been tested for awhile on Solaris.

        Since all I want to do is have my program write a pcap file, I suppose another option is to just write a C program that does this, and add a system() call to the C program from my Perl script. But it would be much nicer if I could do the whole thing in Perl...

      seems your compiler is peaky about the extension of the filename given in the -o <file> option. Does it work if you replace cpp-out.h with cpp.out for example?
