Compiling hping2

[Resident_Geek]

I just installed Red Hat 8.0 (with help from LNO), and I am now trying to compile hping2 to check out its features. I searched through the forums for references to compiling, and read the nhf on compiling software. I downloaded both the beta53 and beta54 versions from kyuzz.org/antirez, and both have the same problem. I run the configure script fine, and then try make. make's output is

gcc -c -O2 -Wall -g -DLIMITWHENSUID -DHAVE_PROC getusec.c
getusec.c: In function `get_usec':
getusec.c:17: `NULL' undeclared (first use in this function)
getusec.c:17: (Each undeclared identifier is reported only once
getusec.c:17: for each function it appears in.)
make: *** [getusec.o] Error 1

I looked, and both the archives seem to be devoid of a setusec.o file. Is that supposed to be the case?Am I doing something wrong? Thanks for any help you can give.

That error says getusec.o because that was the file that was being created when make ran into the error. The actual error was above -- "in function `get_usec': `NULL' undeclared". The NULL symbol is declared to be 0 in at minimum, stdlib.h. If you edit the getusec.c file, and add a #include <stdlib.h> line near the top (probably near the other includes would be good), and try the make again, see if that helps.

It worked! Thanks:)
