CFlow does not build with flow-tools 0.68.1 about flow-tools HOT 9 OPEN

I am maintaining a separate set of patches for flow-tools on FreeBSD/amd64.  We 
have
an extensive perl infrastructure based on Cflow.pm.  If this worked, I'd switch 
over
to the new fork in two, maybe three heartbeats.

I will happily test any patches on FreeBSD, and help get the new version into 
the
official FreeBSD ports tree.  (I'm a FreeBSD committer, I can help do that.  :-)

Hi!

Sorry for huge latency :)

In order to compile Cflow-1.053 on a system where flow-tools is already fully
installed (headers and devel libraries) you need to unpack it somewhere (not to 
the
contrib subdir, but literally, somewhere) and run
perl Makefile.PL CCFLAGS='-DOSU' LIBS='-lft'
make

This will do the trick.

This method is better than contrib/... one because it uses systemwide shared 
libft.so
and allows to properly package perl-Cflow.

I am trying to get Cflow working with flow-tools from this site
http://flow-tools.googlecode.com/files/flow-tools-0.68.4.tar.bz2

Although flow-tools install I am unable to compile Cflow and get that working 
which
is really frustrating.

I keep reading everywhere that:

 This assumes you have flow-tools installed on your system fully, 
including headers
 and development libraries. This is the only supported way to use Cflow.

I am stuck - please can anyone help me - how exactly do I install the headers 
and
development libraries?

I'm stumbling on compiling Cflow-1.053.

I can fiddle Makefile.PL so that it can find the locally-installed flow-tools

(missing at least one symbol:  fterr_setid)

Seems to me that libft.a contains fterr_setid:

Suggestions?

Hello,

Were you able to resolve this particular issue of yours? I too having the same 
exact 
issue.

I've have tried on and off to get Cflow to compile on RHEL5 for months now. It 
always
worked fine on RHEL4. The following posts helped me greatly:

http://biobug.org/index.php/2009/04/03/collecting-netflow-on-rhel5-with-flow-too
ls/
http://onlamp.com/pub/a/bsd/2005/08/18/Big_Scary_Daemons.html?page=4
http://mailman.splintered.net/pipermail/flow-tools/2007-July/003506.html

However, none of those actually worked for me. I compiled a step by step 
solution for
RHEL5 32 bit and 64 bit which worked for me. 


##Clean out any old installations
rm -f /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/Cflow.pm
rm -fR /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/Cflow
rm -fR /usr/local/flow-tools

##Get and build fresh installation
wget http://flow-tools.googlecode.com/files/flow-tools-0.68.4.3.tar.bz2
bunzip2 flow-tools-0.68.4.3.tar.bz2
tar -xvf flow-tools-0.68.4.3.tar
cd flow-tools-0.68.4.3
CC='gcc -fPIC' ./configure (for 64-bit)
./configure (for 32-bit)
make
make install
cd lib
ln -s /usr/local/flow-tools/lib/libft.a libft.a
cd ../contrib
tar -xvzf Cflow-1.053.tar.gz
cd Cflow-1.053
perl Makefile.PL
make
make test (should get OK here, if not it will not work)
make install

I was able to reproduce these results on multiple 32 bit and 64 bit RHEL5 
servers. I
hope this helps others.

Thanks,

WDW

That's the secret sauce right there WDW, thanks.

I had the same issues with Cflow not compiling correctly on opensuse 12.1 with 
flow-tools 0.68.5.1. I'd try to run:

 perl Makefile.PL CCFLAGS='-DOSU' LIBS='-lft'

as it instructs in the /contrib/README, but it would always give me the "Note 
(probably harmless): No library found for -lft" warning. Make would then throw 
the "Cflow.xs:62:21: fatal error: ftlib.h: No such file or directory" error.

WDW's instructions didn't work for me (unfortunately), so to get it to compile 
and have flowdumper actually give me output I did the following:

1 - edited Makefile.PL
     changed this section:

          if (-f '../../lib/libft.a') {
                $dir = '../../lib';
                $incdir = "-I$dir -I$dir/..";
                $libdir = "-L$dir";

     to this:

          if (-f '/etc/flow-tools/lib/libft.a') {
                $dir = '/etc/flow-tools/lib';
                $incdir = "-I/etc/flow-tools/lib -I/etc/flow-tools -I/etc/flow-tools/include";
                $libdir = "-L/etc/flow-tools/lib";

     NOTE: My installation is using /etc/flow-tools, if yours uses /usr/local/flow-tools change these line accordingly

2 - Run this: perl Makefile.PL CCFLAGS='-DOSU'
It could never find the -lft library it needed so I just tried it without this 
and it compiled just fine.

3 - Finish installing
make
make install

4 - Test flowdumper.

Hopefully this works. I spent a ton of time playing around with this to get it 
to work, so hopefully this will help someone else.

Good luck!

Hi,
