Purple Haze v2.1.0

[vincent]

Hi, Everyone.

It has been six months since the previous release and during this time Purple Haze has made good progress. It should not be too far below 2000 ELO by now.

Code: Select all

git diff v2.0.3 v2.1.0 --shortstat
 52 files changed, 1544 insertions(+), 971 deletions(-)

This version mostly contains bug fixes and code improvements but I can now begin to focus solely on tuning the weights of my evaluation function. Preliminary test results show that there is much to gain in this area.

Purple Haze is written in C++11 and is known to compile successfully with GCC >= 4.6 on Debian, Ubuntu and Arch Linux with x86 and ARM architectures. Support of Clang is broken due to a small incompatibility in libstdc++ currently used on GNU/Linux distributions. Support of Intel C++ Compiler is unknown. Support of BSD and Solaris need some work but it should be okay on Windows and Mac OS.

To download and compile Purple Haze:

Code: Select all

$ git clone git://github.com/vinc/purplehaze.git
$ cd purplehaze
$ make

Hi Vincent,
Many thanks for the new version.

I did some 32 bit compiles for Windows, Linux & Android.

Hi Jim,

Thank you very much! I do not have access to Windows machines so I was trying to figure out the problem to cross-compile for this OS from GNU/Linux.

I hope that Gabor will be able to test it now!

I do not have access to Windows machines so I was trying to figure out the problem to cross-compile for this OS from GNU/Linux.

I had exactly the same problem, and found a very nice and portable way of doing it. Simply install the package 'mingw-w64', and replace 'g++' by 'x86_64-w64-mingw32-g++' in your command line (or makefile) to compile.

If you really want to be sure, then you have to install Wine, and you can test your windows compile in command line directly, or even by using a windows GUI like Arena, if you install it. But this is not necessary: it just works

PS: 'mingw-w64' is part of the Ubuntu repositories, so it will work with any Ubuntu based distro (I prefer Lubuntu 12.10 personally). I don't know about other distributions, but I guess most mainstream ones should have it. At worst, you'll have to compile from source (which is a pain in the ass).
And, of course, don't forget to append a '.exe' to the name of the Windows executable. "executableness" is not a property of the file system like on Unix, Windows really only accepts to execute the file if it ends with '.exe'

I did have a small problem compiling with mingw, std::stoi doesn't exist which is a definite bug in mingw. Well actually it does exist but it is being ignored. I found the answer here which involved editing the mingw basic_string.h header > http://stackoverflow.com/questions/8542 ... 1-on-mingw. I use latest version of mingw so this bug still hasn't been fixed.

Hi Lucas,

Don't you also have to cross-compile the C++ Standard Library? I don't use any other dependency like Boost for the main executable but I thought the former was required. I almost always use dynamic languages and Purple Haze is currently the only exception so there is still much to learn!

As a matter of fact, this very week I had to learn a few things about how to write a good Makefile in order to use Travis CI (a distributed build system for continuous integration service). For example you would now be able to invoke "env CXX=x86_64-w64-mingw32-g++ make" directly from the command line which previously required editing the Makefile. "make test" is also smarter and know how to download and compile the Google C++ Testing Framework for executing my unit tests.

Simply install the package 'mingw-w64', and replace 'g++' by 'x86_64-w64-mingw32-g++' in your command line (or makefile) to compile.

This is one way of doing it. Another way is to use autoconf and then to run configure with

./configure --host=x86_64-w64-mingw32

This is what I do for gnuchess.

Don't you also have to cross-compile the C++ Standard Library ?

No, you just compile your code normally. Try it, you'll be amazed
