Problems with gcc compiling Stockfish

[Joerg Oster]

Yesterday I managed to install MinGW (gcc version 4.5.0 for Windows).
But when I try to compile Stockfish 1.8 and it comes to 'Testing config sanity' I get an error message.
Der Befehl "test" ist entweder falsch geschrieben oder konnte nicht gefunden werden. Which means, the command 'test' could not be found.

Am I still missing some files?
In most packages I tried to install 'make' was not included. So I guess there are some more files absent...

Please enlighten me.

Hi Joerg,

In makefile 'Section 4. Public targets'

comment out >

Code: Select all

build:
#	$(MAKE) ARCH=$(ARCH) COMP=$(COMP) config-sanity

Hi Jim,

many thanks.
Finally i can compile my own builds, 32- and 64-bit.

However, if I try to do a profile-build I get another errror message:
process_begin: CreateProcess(NULL, rm -rf *.gcda *.gcno bench.txt, ...) failed
make (e=2): Das System kann die angegebene Datei nicht finden
Any idea?

Another 'problem': Threads are 1 by default, though I have a Quad CPU.
Changing the line "["Threads"] = Option(4, 1, MAX_THREADS);" in ucioption.cpp doesn't seem to help.
Maybe Marco can help on this one?

Joerg.

Set UCI "Threads" parameter to the number you prefer before to start the game.

Hi Marco,

wow, you're fast.

Yes, playing in a GUI or even with cutechess-cli this is no problem.
But I also wanted to do some benching with different settings. Hence the question.

Joerg.

Try this:

Code: Select all

--- a/src/ucioption.cpp
+++ b/src/ucioption.cpp
@@ -178,7 +178,7 @@ void init_uci_options() {
   Option& thr = options["Threads"];
   Option& msd = options["Minimum Split Depth"];
 
-  thr.defaultValue = thr.currentValue = stringify(cpu_count());
+  thr.defaultValue = thr.currentValue = 4;
 
   if (cpu_count() >= 8)
       msd.defaultValue = msd.currentValue = stringify(7);

Makefile is designed for Linux/Unix, so some parts won't work under Windows. Anyway ordinary builds are more than enough if you want to experiment with your own ideas. With profile-builds you can get around 5% more speed, but because you are usually only interested in strength difference between original and modified versions, it doesn't matter.

Hi Joona,

of course, you are right.
Anyway, thanks for the explanation.

Joerg.

Hi Marco,

thanks for your help.
But I just noticed, that with the bench command you can specify how many threads to be used, as well.

Joerg.
