Here's a followup on my earlier message...
I have gotten rid of the compilation errors and now turn to what remains.
[I must stress I made some guesses and it isn't clear that even if I can
get past the remaining issues that the result will be working code.]
Here's what I'm seeing in terms of errors (at least this is what gcc is
saying after suppressing warnings):
# make
gcc -O2 -Wall `libnet-config --defines` \
-o tcptraceroute tcptraceroute.c \
-I /sw/include -L /sw/lib \
`libnet-config --libs` -lpcap -w
tcptraceroute.c:231: warning: ANSI C forbids newline in string constant
tcptraceroute.c:773: warning: ANSI C forbids newline in string constant
tcptraceroute.c: In function `capture':
tcptraceroute.c:972: dereferencing pointer to incomplete type
tcptraceroute.c:983: dereferencing pointer to incomplete type
tcptraceroute.c:984: dereferencing pointer to incomplete type
tcptraceroute.c:986: dereferencing pointer to incomplete type
tcptraceroute.c:1009: dereferencing pointer to incomplete type
tcptraceroute.c:1016: dereferencing pointer to incomplete type
tcptraceroute.c:1029: dereferencing pointer to incomplete type
tcptraceroute.c:1033: dereferencing pointer to incomplete type
tcptraceroute.c:1075: dereferencing pointer to incomplete type
tcptraceroute.c:1080: dereferencing pointer to incomplete type
tcptraceroute.c:1082: dereferencing pointer to incomplete type
tcptraceroute.c:1090: dereferencing pointer to incomplete type
tcptraceroute.c:1110: dereferencing pointer to incomplete type
make: *** [tcptraceroute] Error 1
#
I've hit a roadblock with the "dereferencing pointer to incomplete type" errors above
The rub is if I look at line 972 I don't see anything clearly applicable to the error.
For example, the error at line 1082 is a blank line. The warnings for line 231 and 773
are contextually correct -- see what the warning is citing.
I'm using the December 2002 Developer Tools should anyone wish to know. The gcc
version
is "gcc (GCC) 3.1 20020420 (prerelease)".
Anyone able to help me either make the error line number be correct for the errors or
able to give me a workaround to determine the line number?
