Programming

I don't know if this is the correct forum to post this but hopefully someone can atleast point me in the right direction if they can't help me.

I am trying to install the Net::Pcap module for perl from Tim Potter version .04. I have installed gcc 2.95.3 on my Solaris 8 box. I am sure it's just a config/option issue with gcc. When I run:

perl Makefile.PL

I get this:

Note (probably harmless): No library found for -lpcap
Writing Makefile for Net::Pcap

If I manually try to compile Pcap.c using this (I know there are more options I should use but I am not hugely familiar with gcc):

gcc Pcap.c

I get this:

All the .h files are in my /usr/perl5/5.00503/sun4-solaris/CORE directory.

The README for Pcap mentions they successfully tested on Solaris 2.6 with gcc 2.8.1.

Any help is appreciated.

Ok, so far so good. Now just run "make".

Thanks for the reply.

When I run make I get this:

cc -c -xO3 -xdepend -DVERSION=\"0.04\" -DXS_VERSION=\"0.04\" -KPIC -I/usr/perl5/5.00503/sun4-solaris/CORE Pcap.c
/usr/ucb/cc: language optional software package not installed
*** Error code 1
make: Fatal error: Command failed for target `Pcap.o'


I do not have cc, only gcc. I cannot figure out the options I need to use for gcc to work properly. The readme says they compiled successfully with gcc but don't say how. Any thoughts?
Thanks,

Edit "Makefile". Find The CC=cc and change it to CC=gcc (I hope it exists). I have also the feeling (alsmost certainty) that this pcap.c needs the libpcap library compiled and installed first. Note that you probably will have to make changes to other things in Makefile. I.e. I suppose that the -KPIC directive should change to -DPIC. Try to find if there is a script with name "configure" there (I dont think so...). If it exists execute it.

Greetings

Thanks for your help thus far. I changed the cc to gcc in the Makefile, which I had done before as well. I think the key was changing KPIC to DPIC. That seems to have gotten me further. There is no config file. When I run make, I now get this:

gcc -c -xO3 -xdepend -DVERSION=\"0.04\" -DXS_VERSION=\"0.04\" -DPIC -I/usr/perl5/5.00503/sun4-solaris/CORE Pcap.c
gcc: language depend not recognized
gcc: Pcap.c: linker input file unused since linking not done
Running Mkbootstrap for Net::Pcap ()
chmod 644 Pcap.bs
LD_RUN_PATH="" gcc -o blib/arch/auto/Net/Pcap/Pcap.so -G Pcap.o
gcc: Pcap.o: No such file or directory
gcc: No input files
*** Error code 1
make: Fatal error: Command failed for target `blib/arch/auto/Net/Pcap/Pcap.so'

All the paths mentioned exit but Pcap.so is not in blib/arch/auto/Net/Pcap/. Where do I go from here? Does anyone know of any good gcc 101 sites that could help me out?
Thanks,
TioTony

i believe the -x directives are now wrong. The -xO3 i presume it is the optimization. Remove it completeley or try simply -O3. To see the options of gcc simply type #man gcc. If it is not listed, it is not supported. If #man gcc doesnt work try this:

#cd /usr/local/bin/man/man1
#nroff -man gcc.1 |more

Note it is a difficult matter if there is no config file

Thanks, I guess I'll just keep struggling with it.
