crc32.cpp compile error

[qwicfingers]

I'm getting a compile error when I try to compile the world. :sad: Any help would be greatly appreciated.

lets see..
Intel p4
Ubuntu8.4 server
EQEmu-0.7.0-1118
tried both g++4.1 and 4.2

make clean and make depend work fine, but errors when I make

../common/crc32.cpp:105:2: warning: #warning "Comment out i386 define if your arch isn't x86"
../common/crc32.cpp: In static member function

Looks like that is just a warning to me. You can ignore warnings, there are always tons of them. As long as you don't get an actual error, you are ok.

hmm just noticed that for some reason copy and paste failed me...

this is the error bit

../common/crc32.cpp:238: error: PIC register \‘bx\’ clobbered in \‘asm\’
make[1]: *** [../common/crc32.o] Error 1

I don't know much about Ubuntu (I run debian), but if the compile is thinking you don't have x86 architecture, then maybe you are running the wrong kernel. I would check into upgrading your kernel to the right one for your P4.

You might also want to look over some of the wikis on Linux Servers from this page:

Remove the "-Di386" directive from the makefile and it should compile fine.

cool thanks, I'll give that a try.

I noticed the newer the version distro I have, harder it gets to make a working EqEmu compile - I have one machine that compiles the emulator fine. it's Mandriva and has been updated for a few years now - it still uses gcc-3.4.6 and I 'think' this is why it still compiles. I have a machine with a new Mandriva (2008.1) which carrys gcc ver 4.2.3, and I've seen this error you have and a few others (using the same source). It became a challenge (for a while), and I actually got everything to compile void world and the 'clobbered' error. I did a lot of Googling on this error and it usually pointed to the new gcc version. I tried installing the 3.4.6 on my newer machine but then got other errors, really wasn't that important to me (since I already can compile on the older -version machine), so I gave it up.
If you want to try my version ( gcc-3.4.6.tar.gz ), I can post it for you- It's source, and will compile just about anywhere (unlike EqEmu).

Hmmm. I'm using Fedora Core 8 with gcc 4.1.2 and I compiled the emu without any problems, including the bot code. So I don't think it's 4.1, but it might be 4.2 that's causing some issues. I'm not planning to go to FC9 anytime soon, so hopefully mine will continue to work.

Gave removing -Di386 a go and I get the same error. Tried gcc3.4.6 compile fails much earlier at EMuShareMem with a different error. Everything other then the world compiles fine with 4.2

What about the -march=i686 flag? I know the ubuntu kernel version is i386.

I am on a 64bit platform and use a i386 chroot environment to compile and use eqemu.
to compile the i have to add #undef i386 in crc32.cpp


#include "crc32.h"
#include <assert.h>
#include <memory.h>
#undef i386
int32 CRC32Table[256] =
{
...

adding #undef i386 to my crc32.cpp worked. Thank you.

this also worked for me.
