VS2008 Compilation Issue: Cannot open include file: 'immintrin.h'

[russellwinstead]

I was looking at making simple python wrappers for the zstd library, and I ran into the following issue when compling on Windows using VS2005:

lib\zstd.c(69) :fatal error C1083: Cannot open include file: 'immintrin.h': No such file or directory

It appears to come from this line.

Yes, indeed.
immintrin.h is about AXV2 extension.
So it's probably not available on VS2005.

The manual solution is to comment this line : the associated code will be removed from compilation.

What I'm lacking currently is a way to achieve this conditional #include automatically.

Maybe just excluding VS2005 would be a good enough start ?

There is a tentative fix for your configuration within the "dev" branch of zstd :

For your testings

Sorry, I said 2005 but I meant 2008. After changing _MSC_VER<=1400 to _MSC_VER<=1500 everything turned out ok.

OK, "dev" branch updated
