Chess engines compilation

[catalano7777]

I think you are missing experience.cpp for an object file compilation.

### Source and object files
SRCS = benchmark.cpp bitboard.cpp evaluate.cpp main.cpp experience.cpp \
misc.cpp movegen.cpp movepick.cpp position.cpp psqt.cpp \
search.cpp thread.cpp timeman.cpp tt.cpp uci.cpp ucioption.cpp tune.cpp syzygy/tbprobe.cpp \
nnue/evaluate_nnue.cpp nnue/features/half_ka_v2_hm.cpp \
book/book.cpp book/polyglot/polyglot.cpp book/ctg/ctg.cpp

After adding it to the makefile, it compiled for me.

Thank you, Sarona,
but, as you can see, experience.cpp file is in my folder

I think there must be an error with patch updating to SF MZ version...

As Sarona said: You have to CHANGE the Makefile according to his advices.

Ahhh, ok! I had misunderstood the instruction.
Finally, after fixing the Makefile, the build worked.
Thanks a lot!

The declaration is missing in the Makefile. I do not know the specfic line number. Can't check at the moment (using my phone).

Thank you very much, sarona!! It worked perfect.

The line number is #59

I would have been clearer had I been home. I was reading through the forum on my phone while eating breakfast in a small diner ( worst pancakes ever ) and read through your compiler log.

Use WinMerge to compare sources with Windows OSs. Very good tool for such tasks. I think M.Z mentioned this years ago.

If possible, try to always embed the NNUE network.

and add this parameter to the compiling command: COMP=mingw. If for some reason the compiler uses COMP=gcc, the produced executable won't work outside the compiler environment without its relative libraries.

Proper compiling command example:
make -j profile-build ARCH=x86-64-bmi2 COMP=mingw

I have some problems with engines compiled with MingW and msys2.When I click on compiled .exe file when it's still in folder src and run bench it's ok and run normally.But when I move the engine.exe anywhere,when click on .exe and run bench it's only flashes and command window dissapears.If I put the engine in Arena GUI it's running properly.What could be causing this problem?
P.S. I"ve reinstalled MingW and msys2,but the problem had remained.

A few months ago from debian I managed to compile, but from windows, not even wanting to. Of course I don't know how to program, etc. And I'm sure I left something. I have tried to do it as Mz comments. the variables in your path and the same with the lib folder. But nothing, the console says that it is not a valid directory, etc. I am clumsy and of course when you are faced with an unknown language, I imagine that someone who knows how to program sees it as easy, but I despair.... hehehehhe.

DO you know which lines should I add to make NNUE embed network in c++ files?

Thank you!

Current Stockfish development makefile has embedding set as default in line 370.

For embedded net
CXXFLAGS = $(ENV_CXXFLAGS) -Wall -Wcast-qual -fno-exceptions -std=c++17 $(EXTRACXXFLAGS)

For external net
CXXFLAGS = $(ENV_CXXFLAGS) -Wall -Wcast-qual -fno-exceptions -std=c++17 -DNNUE_EMBEDDING_OFF $(EXTRACXXFLAGS)

The compilation error only concerns Brain Learn.

Hello. Where i can download MinGW GCC 10.2.0? If possible an official site with compilers

I guess the error you are getting is related to curl, right? Or can you specify whats the error?

If it is the curl related error probably when you try to compile it it says:"curl/curl.h file does not exist" or something similar.

In my case, under Ubuntu 22.04 I managed to fix it in this way:

Code: Select all

sudo apt-get install libcurl4-openssl-dev
cd /usr/include/x86_64-linux-gnu
sudo mv curl ..

Hope it helps,

If anyone have, can post a link with this compiler I see that was deleted
