[SOLVED] Compiling Ogre for android target aarch64 with boost support

MikmakOne · Post by **MikmakOne** » Tue Jun 05, 2018 4:14 pm

Hi all,
I almost did it but still am fighting with the boost support which is causing some cmake build issues.
I am compiling against the android-21 API with the aarch64-linux-android-4.9 toolchain the Ogre 1.10 release which seems a bit messy for what it is the boost support.
I will try to explain what the issue is but before let me specify that the cmake build procedure correctly detects both the boost headers and libs.
And this is the cmake build script that I am using:

Code: Select all

#!/bin/bash

DIR=$(pwd)

API_LEVEL=21

ABI_VER=arm64-v8a
#ABI_VER=armeabi-v7a

NDK_TOOLCHAIN=aarch64-linux-android-4.9
#NDK_TOOLCHAIN=arm-linux-androideabi-4.9

OGRE_INSTALL_PREFIX=$DIR/ogre_2_0/ogre
OGRE_DEPS=$DIR/ogre_deps/libs
OGRE_CMAKE_TOOLCHAIN=$DIR/ogre_2_0/CMake/toolchain/android.toolchain.cmake

mkdir -p ./ogre_2_0/build
cd ./ogre_2_0/build

#unset BOOST_INCLUDEDIR
#unset BOOST_LIBRARYDIR
#unset BOOST_ROOT
#export BOOST_INCLUDEDIR=$MYBOOST_INCDIR
#export BOOST_LIBRARYDIR=$MYBOOST_LIBSDIR
#export BOOST_ROOT=$BOOST_PATH

#BOOST_DIRS="-DBOOST_INCLUDEDIR=$BOOST_PATH/include/boost-1_67/boost -DBOOST_LIBRARYDIR=$BOOST_PATH/libs/lib"


MYBOOST_FLAGS="-DBoost_COMPILER=-gcc -DBoost_DEBUG=ON -DBoost_DETAILED_FAILURE_MSG=ON -DBoost_USE_STATIC_LIBS=ON -DBoost_USE_MULTITHREADED=ON -DBoost_USE_STATIC_RUNTIME=ON -DBoost_USE_DEBUG_LIBS=OFF -DBoost_USE_RELEASE_LIBS=ON -DBoost_NO_SYSTEM_PATHS=ON"
#MYBOOST_FLAGS="-DBoost_COMPILER=-gcc -DBoost_DEBUG=TRUE -DBoost_USE_STATIC_LIBS=ON -DBoost_USE_MULTITHREADED=ON -DBoost_USE_STATIC_RUNTIME=TRUE"

cmake -G"Unix Makefiles" -DCMAKE_MAKE_PROGRAM="$ANDROID_NDK/prebuilt/linux-x86_64/bin/make" -DCMAKE_TOOLCHAIN_FILE=$OGRE_CMAKE_TOOLCHAIN -DCMAKE_INSTALL_PREFIX=$OGRE_INSTALL_PREFIX $MYBOOST_FLAGS -DOGRE_DEPENDENCIES_DIR=$OGRE_DEPS -DBOOST_INCLUDEDIR=$OGRE_DEPS/include/boost -DANDROID_ABI=$ABI_VER -DANDROID_NATIVE_API_LEVEL=$API_LEVEL -DANDROID_TOOLCHAIN_NAME=$NDK_TOOLCHAIN .. && make all install

cd ../..

The main issue seems to be some messy pthread (STD thread support) which is fighting with the BOOST one and this happens only if boost is correctly detected (to be clear, this is the case when the configuration once completed shows the thread model to be background (boost)
As a result I get a CMakeOutput.log file with the following content:

Code: Select all

}

It seems to me that the crucial part which is handling the threading support for Ogre is being located in the PATH_TO_OGRE_SRC/CMake/ConfigureBuild.cmake
And to be clear, I just tried to disable the pthread support there but with no luck.
Thanks you in advance!

Well, just downloaded Ogre 1.11 and I did notice that boost is not being used at all for the android target - this is the build config result:

Code: Select all

Building components:
  + Bites
  + HLMS [BETA]
  + MeshLodGenerator
  + Overlay
  + Paging
  + Property
  + Java/ JNI [BETA]
  + RTShader System
  + RTShader System Core Shaders
  + RTShader System Extensions Shaders
  + Terrain
  + Volume
Building plugins:
  + Octree scene manager
  + STBI codec (generic)
  + FreeImage codec (generic)
  + Particle FX
Building rendersystems:
  + OpenGL ES 2.x
Building executables:
  + Samples
Building core features:
  + Mesh Lod
  + DDS image codec (.dds)
  + PVRTC image codec (.pvr)
  + ETC image codec (.pkm, .ktx) 
  + ZIP archives

Build type:                      static
Thread safety:                   none
ResourceManager behaviour:       strict
Use double precision:            disabled
Nodes inherit transform:         disabled
Assert mode:                     release exceptions

----------------------------------------------------------------------------

    Boost_USE_DEBUG_LIBS
    Boost_USE_MULTITHREADED
    Boost_USE_RELEASE_LIBS

I guess that the c++11 adoption for this release has let boost being marked as deprecated - also this is what it can be found in the main CMakeLists.txt
We can close this discussion then
