Dbyte_order_(big|little)_endian

I'm trying to compile hping3 on CentOS 5.5 X64 and getting the following:

Code:

[root@forge hping3-20051105]# ./configure --no-tcl

now you can try `make'

I've tried adding -DBYTE_ORDER_(BIG|LITTLE)_ENDIAN to the Makefile and it didn't help. I noticed it says "fix bytesex.h", so I tried adding it there too and that didn't help either. There's code in bytesex.h regarding BIG/LITTLE ENDIAN too:

Code:

#ifndef ARS_BYTESEX_H
#define ARS_BYTESEX_H

#if     defined(__i386__) \
        || defined(__alpha__) \
        || (defined(__mips__) && (defined(MIPSEL) || defined (__MIPSEL__)))
#define BYTE_ORDER_LITTLE_ENDIAN
#elif   defined(__mc68000__) \
        || defined (__sparc__) \
        || defined (__sparc) \
        || defined (__PPC__) \
        || defined (__BIG_ENDIAN__) \
        || (defined(__mips__) && (defined(MIPSEB) || defined (__MIPSEB__)))
#define BYTE_ORDER_BIG_ENDIAN
#else
# error can not find the byte order for this architecture, fix bytesex.h
#endif

#endif /* ARS_BYTESEX_H */

Can anybody make sense of this? I've ran into compilation errors before with other software but nothing quite as kinky as this.

The pipe symbol in parenthesis is a short way of saying "either-or". It's trying to tell you to add either "-DBYTE_ORDER_BIG_ENDIAN" or "-DBYTE_ORDER_LITTLE_ENDIAN" to the Makefile, depending on whether the machine you're trying to run this on is big-endian or little-endian. However, exactly where to add it can be a little tricky, since the Makefile will usually be regenerated from Makefile.in by configure, and it might need to be put in at several different places.

You're probably better off editing bytesex.h. Comment out the "# error" line, and add "#define BYTE_ORDER_BIG_ENDIAN" or "#define BYTE_ORDER_LITTLE_ENDIAN" just after it, again, depending on your architecture.

Ahhhh, just like grep, I should have known that.

I added #define BYTE_ORDER_LITTLE_ENDIAN to bytesex.h after commenting out the error line and hping3 compiled successfully! I really appreciate the help.
