OK, installed gcc 5.3 and get the same error in nice colors now. Has to be some Mac specific?!

$ gcc -v

sorry, I can't help.
my understanding of the thread bind code is very basic, it compile on windows. I tried to modify it and it stop compiling in windows. I haven't a macos.

I'll try to compile it in a linux environment. In windows I'm using posix thread config.

I'll let you know if I found where the problem is.

Hi Marco,

It turned out that Vajolet relies upon a couple of features supported only by GCC, but the GitHub master lacks a Makefile. Can you provide a Makefile for my students to compile a 64-bit Vajolet 2.1 for FOSCEC Season 3 using MinGW 4.9.2? We'd like to support AVX2.

Best regards,
Dmitri

I'm pleased to release a new release of Vajolet2

this is my first version with lazy smp code. despite lot of works and debugging the new version is probably ony few Elo point stronger.

in the zip you could find a 64 bit executable, a 32 bit executable and old 64bit version compiled for Gabor Szots


you can download it at

I made my compile of Vajolet2 2.1 capable of running up to 16 threads available at http://www.firenzina.org/Vajolet2.zip.
Many thanks to Marco for his advice on how to compile his engine! I used the 64-bit MinGW 4.9.2 under Eclipse Kepler C++ for Windows.

You need DLLs for the 64-bit MinGW 4.9.2 to make this one work.

probably if you static link the executable you don't need the dll
