Thanks. You're the third person to send me gcc4 patches in the past week. 0.69 will have all this fixed, just need to get a box with gcc4 running.

Greetings -

I'm attempting to compile flow-tools on a fedora core 4 test (yes, I
know it's a test release.  it's a long story) and I get the following
from make:

Making all in lib
make[1]: Entering directory `/var/netflow/installs/flow-tools-0.68/lib'
make  all-am
make[2]: Entering directory `/var/netflow/installs/flow-tools-0.68/lib'

|| echo './'`ftio.c
ftio.c: In function 'readn':

make[2]: *** [ftio.o] Error 1
make[2]: Leaving directory `/var/netflow/installs/flow-tools-0.68/lib'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/var/netflow/installs/flow-tools-0.68/lib'
make: *** [all-recursive] Error 1

I get the same results from 0.66 or 0.68 compiles.
This is gcc verison 4.0.0.

Can anyone tell me if this is even possible?

The line in question is:

(char*)ptr += nread;

Try changing it to this:

ptr = (void*)( ((char*)ptr) + nread);

Same story for the other line.

I don't have access to gcc4 so I can't test it.

Roger and I worked a bunch of these out and came up with a patch (attached).
