compiling crafty

[survi...@my-deja.com]

I'm trying to compile a program named crafty (public chess program). I get
the following error:

gcc -c -fomit-frame-pointer -m486 -O3 -DCOMPACT_ATTACKS

Any ideas?

I'm guessing that X86.s is actually X86.S (with a capital .S), and
should be passed through the preprocessor before the assembler.

Try this from the command line and see if it works:

gcc -c X86.S

If it works, replace the command in the Makefile.

If that doesn't help, post the file X86.s here.

Well, the actual file had a lower-case .s extension. But I tried the
command gcc -c x86.s and it gave me the same errors. Then I tried the
same command, but capitalized the .s to .S anyway, and it gave me the
same kind of errors, but slightly different - very strange:

[Norberto Alfredo Bensa]

This is the problem.... X86.s

alignment = ALIGN

.text
.align alignment, 0x90
globl _PopCnt
_PopCnt:
movl 4(%esp), %ecx

ALIGN isn't defined!
Open X86.s and change the first line so it reads:

alignment = 4

That's all.

Best regards,
Norberto
