Hi all!
I have just successfully built openssl-0.9.5beta1 on NT 4 with VC++ 6.0 and
MASM 6.14. I had to "tweak" two thing to get it through.
My setup is this:
> perl Configure VC-WIN32
> ms\do_masm
> nmake -f ms\ntdll.mak
I'm not on this list, so you may CC any comments to me.
First one, short version
========================
I need this patch to make openssl-0.9.5beta1 compile clean with MASM 6:

Why?

I get this error:

Stop.
This is (hopefully) the interesting parts of crypto\sha\asm\s1-win32.asm:
TITLE sha1-586.asm
.486
.model FLAT
_TEXT SEGMENT
PUBLIC _sha1_block_asm_data_order
_sha1_block_asm_data_order PROC NEAR
<snip>
mov DWORD PTR 132[esp],esi
L001shortcut:
;
<snip>
ret
_TEXT SEGMENT
PUBLIC _sha1_block_asm_host_order
_sha1_block_asm_host_order PROC NEAR
<snip>
jmp L001shortcut
_sha1_block_asm_host_order ENDP
_TEXT ENDS
_sha1_block_asm_data_order ENDP
_TEXT ENDS
END
Now, I'm by no means a MASM expert, but it seems that labels with a single
colon, ":", is scope dependent. So the "L001shortcut:" label isn't visible
in the scope of "_sha1_block_asm_host_order PROC NEAR". To make labels
"global", they should be suffixed with double colons, "::", like
"L001shortcut::".
Cheers,
- Peter
