Need Help Getting GCC Working?!?

[Steve Maughan]

Are there any Ninja compiler experts who can help me?

I have Maverick doing error free perft in a Microsoft Visual Studio Express 2012 environment. I was about to plunge into developing the evaluation function. But then I thought now is probably a good time to get GCC working. A couple of reasons for this:

1. Since Maverick is a bitboard program I'd like it to work on a 64 bit platform (I think it is possible with Express, but so far I haven't been able to get it to work)

2. Once I have 64 but working I can utilize the SSE 4.2 bit-flipping intrinsics (e.g. popcount etc.) to get a nice speed-up

3. I've heard the latest version of GCC is as good as, or better than, Microsoft for 64 bit compiles (so why pay $500 for Microsoft's Professional version).

But the task doesn't seem to be trivial. Although I'm certainly no expert when it comes to C or C++ development.

Can anyone help me - I'd certainly appreciate it!

You can find the zipped source, along with all the MSVC file here:

Using Express 2012 it compiles nicely. I have it set to use multi-threads (which I use for getting user input) and it's compiling as C++ (mainly for variable declarations in the middle of a procedure). The only real command which works is "testperft".

I've tried to get it working using the NetBeans and Code::Blocks IDEs in 32 bit mode but to no avail. The GCC compiler seems to get stuck on

Code: Select all

t_chess_move_type 

enumerated type whoch occurs in

Code: Select all

t_move_record

- I've no idea why!

Any help appreciated!

Many Thanks,

Steve

Your zipped source code is 9 MB. What did you put in there? A Trojan horse :p

I cannot compile it either, because it's infamously non portable. Your main.c starts with

Code: Select all

#include <windows.h>

but doens't even use anything from windows.h !?

I have succeeded in compiling Maverick with g++ (mingw), it runs but it doesn't start searching at all when asked to.
I succeeded in compiling under VS2012 as c++ code, but I got these warnings:
Source\genmoves.cpp(308): warning C4333: '>>' : right shift by too large amount, data loss
Source\genmoves.cpp(312): warning C4333: '>>' : right shift by too large amount, data loss
Where you shift right an unsigned char by 8, I wonder if that was intended?

test.cpp(49): warning C4715: 'test_bitscan' : not all control paths return a value

PS you don't need to include .sdf in the archive.

Compiling this under MinGW and gcc 4.8 64bit your problem seems to be the 3 inline function definitions in bitboards.c need to be in a header (so they are visible to any tralnslation unit using them). Moving that code and it compiled and ran testperft as 64bit.

Same for the .suo file.

Hi James,

Thanks. They are already in "procs.h". Apologies for the newbie questions but can I ask where you put them so that it compiled? Also, what environment did you use to compile it?

Thanks,

Steve

Hi Lucas,

Sorry - one of the MSVC files was massive. I didn't need it, so removed it. And I've removed <windows.h>

Thanks,

Steve

Hi Martin,

The shift were intended for pawn moves. There is no data loss since there are never any pawns on the first or eighth row.

I'll take a look at test_bitscan.

I still can't get it to compile. Can I ask what GCC IDE / environment did you use to compile it? Did it start searching after typing "testperft"?

Thanks,

Steve

Thanks Sven - noted!

Hi, I actually meant the code, not just the definition (function signature).

As for the environment I just grabbed a a build from http://sourceforge.net/projects/mingw-w ... %20Builds/ (the actual one was http://sourceforge.net/projects/mingw-w ... 8-release/) and ran the setup script in it, then I just ran "gcc *.c -o Maverick.exe" to build from the source directory.

You'll need also need the MSYS tools or cygwin in your path environment variable but you can get that from a real release and 32bit is fine is they are just supporting tools.
