can't compile v0.9

[pw31]

On Ubuntu 14.04 with gcc 5.5.0:

cmake -DFEATURE_USE_CPU_ONLY=On -DBLAS_INCLUDE_DIRS=/usr/include .. make ... /home/star/pw31/chess/Engines/LCzero/leela-chess/src/Network.cpp:37:36: fatal error: boost/spirit/home/x3.hpp: No such file or directory

This was working before. Any idea?

[ganeshkrishnan1]

I could fix it by commenting out init(); method in pgn.cpp.

pgn.h has changed and the author forgot to comment the overriden method I guess

[pw31]

Hi @ganeshkrishnan1, thanks! Unfortunately, and I'm really feeling stupid right now, I cannot find "init()" in src/pgn.cpp. Would you have a line number for me please?

[ganeshkrishnan1]

Unfortunately I am running a fork of leela chess and I just noticed this master doesn't have the init() method. Sorry I feel stupid now. Past my bedtime!

I am able to compile fresh version of 0.9 so I guess your issues would have to be with your local system setup

Seems that boost spirit x3 is not supported by boost 1.54.0 which currently is the required minimum boost version. Ubuntu 14.04 only offers support until 1.54.0. My problem might be solvable by a custom installation of a more recent boost version, see https://www.boost.org/doc/libs/1_66_0/more/getting_started/unix-variants.html#get-boost. I did that, but now I'm stuck because I don't know how to tell cmake to use that compilation rather then the default one on the system. I just don't understand cmake.

cmake -DBOOST_ROOT=/data/pw31/software/boost_1_66_0/ ..

causing warnings as CMake Warning at /usr/share/cmake-3.5/Modules/FindBoost.cmake:725 (message): Imported targets not available for Boost version 106600 Call Stack (most recent call first): /usr/share/cmake-3.5/Modules/FindBoost.cmake:763 (_Boost_COMPONENT_DEPENDENCIES) /usr/share/cmake-3.5/Modules/FindBoost.cmake:1332 (_Boost_MISSING_DEPENDENCIES) CMakeLists.txt:29 (find_package)

but then make stops with error

Having a similar issue.

After cmake command: cmake -DFEATURE_USE_CPU_ONLY=On ..

I got the following error message:

-- The CXX compiler identification is unknown -- The C compiler identification is GNU 5.4.0 CMake Error at CMakeLists.txt:15 (project): No CMAKE_CXX_COMPILER could be found.

Trying to compile on google compute cloud with Ubuntu 16.04.

Ok, now I feel stupid :)

Installed build-essential and edited CMakeLists.txt to point CMAKE_CXX_COMPILER to g++ and problem solved.

My problem still not solved. I managed to compile and install boost_1_66 as decribed here https://coderwall.com/p/0atfug/installing-boost-1-55-from-source-on-ubuntu-12-04 (using directory /data/pw31/software/boost) Then I setup compilation with

cmake -DFEATURE_USE_CPU_ONLY=On -DBLAS_INCLUDE_DIRS=/usr/include -DBOOST_ROOT=/data/pw31/software/boost/ ..

which already results in some warnings as -- The CXX compiler identification is GNU 5.5.0 -- The C compiler identification is GNU 5.5.0 -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Found PythonInterp: /home/star/pw31/software/anaconda/bin/python (found version "2.7.14") -- Looking for pthread.h -- Looking for pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- Check if compiler accepts -pthread -- Check if compiler accepts -pthread - yes -- Found Threads: TRUE

... and then "make" results in ...

where "DSO" is a dynamic shared object, or a shared library in other words. I am missing a library in linking stage. I confirm that /data/pw31/software/boost/lib/libboost_system.so.1.66.0 is there, created by my boost_1_66 installation, which I think was successful. I realize that /usr/share/cmake-3.5/Modules/FindBoost.cmake was used, which comes from the system boost 1.54 installation.

Any help would be appreciated.
