Net::Pcap install problem

jblevin has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

I'm running into problems trying to install Net-Pcap-0.14. I run 'perl Makefile.PL INC=... LIBS=...' (INC and LIBS path details left out)

I get the following error:

error: system call to 'cc -E -I/usr/add-on/exptools/lib/pcap/include -DHAVE_BLANK -DHAVE_PCAP_LIB_VERSION find-funcs.h -o cpp-out.h' failed at Makefile.PL line 326.

I see in the README file, "To install the extension in a private directory, you can use the PREFIX option when creating Makefile.PL". I don't know if the reason for the above error is that I need to tell it to install the extension in a private directory. If so, I don't know what it means to "use the PREFIX option when creating Makefile.PL". Makefile.PL is already created in the downloaded package. I don't see any PREFIX option in Makefile.PL. I tried to run 'perl Makefile.PL PREFIX=..." to point to my private path, this didn't work either.

Seems like they are leaving out some of the details here. Any tips would be greatly appreciated - Thanks!

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.) -Paul	[reply]

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.

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. -Paul	[reply]

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 +dout` [download] Maybe you could try redirecting the output `cc -E ... find-funcs.h > cpp-out.h` [download] Just an idea...

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? cheers --stephan	[reply]
