Build with nasm 2.14.02 fails on win64

[gabrielschulhof]

I get isa-l_crypto\sha256_mb\sha256_mb_mgr_flush_avx2.asm:99: error: COFF format does not support any special symbol type when I try to assemble this file on Windows.

Is there a way around this?

[gbtucker]

You should have got %error nasm not supported in windows. You need to switch to yasm in windows for now.

[gabrielschulhof]

@gbtucker OK, I'll try to get yasm running.

[gbtucker]

@gabrielschulhof, nasm should work now. You might give it another try.

Hi @gbtucker , I get below error while building isa-l_crypto on win64

nasm --version
NASM version 2.14.02 compiled on Dec 26 2018

nmake -f Makefile.nmake
....
....

Do you know if this is a known issue or how to resolve it?

[gbtucker]

Thanks @arun-kv, looks like we may have left out a few files from nmake. Can you try again from tip I just pushed b524e65?

@gbtucker its still failing.

Stop.

I have actually tried the same fix before asking the question.

[gbtucker]

Thanks again @arun-kv. I think I found a simple solution to this issue also. I'm pushing through testing now and trying to see why it wasn't caught.

@gbtucker thank you so much for the help, its getting compiled now.

The test directory is not getting compiled, so i have made the below changed to make it work.

Thanks for testing this. As openSSL changed the lib name in 1.1.0 we should change also.
