安装

Linux端的安装

sudo apt install libcgal-dev

Android端的编译

官方指南: github

指南镜像地址

生成toolchain

直接使用Android Studio的ndk

${ANDROID_NDK}/build/tools/make_standalone_toolchain.py --arch ${ARCH} --install-dir ${TOOLCHAIN_PATH}

• ${ANDROID_NDK}: /home/lynx/fuck_mount/AndroidSDK/ndk/21.3.6528147
• ${ARCH}: arm64
• ${TOOLCHAIN_PATH}: 安装位置

编译GMP

官网下载

export CC=${TOOLCHAIN_PATH}/bin/clang
export PATH="${TOOLCHAIN_PATH}:${PATH}"
./configure --prefix=${GMP_PATH} --enable-shared --host=${TARGET_TRIPLET}
make
make install

• ${GMP_PATH}: 安装位置
• ${TARGET_TRIPLET}: aarch64-linux-android

编译MPFR

官网下载

export CC=${TOOLCHAIN_PATH}/bin/clang
export PATH="${TOOLCHAIN_PATH}:${PATH}"
./configure --prefix=${MPFR_PATH} --enable-shared --host=${TARGET_TRIPLET} --with-gmp=${GMP_PATH}
make
make install

• ${MPFR_PATH}: 安装位置

编译boost

官网下载

下载cgal源码

github镜像

选择Source code

cmake编译

先创建toolchain.cmake

set(CMAKE_SYSTEM_NAME  Android)
set(CMAKE_SYSTEM_VERSION 21)
set(CMAKE_ANDROID_ARCH_ABI arm64-v8a) # Change arm64-v8a to armeabi-v7a for 32bit phones
set(CMAKE_ANDROID_NDK /home/lynx/fuck_mount/AndroidSDK/ndk/21.3.6528147)
set(CMAKE_ANDROID_NDK_TOOLCHAIN_VERSION clang)

set(GMP_INCLUDE_DIR /home/lynx/darkin_blade/cgal/gmp/include)
set(GMP_LIBRARIES /home/lynx/darkin_blade/cgal/gmp/lib/libgmp.so)

set(MPFR_INCLUDE_DIR /home/lynx/darkin_blade/cgal/mpfr/include)
set(MPFR_LIBRARIES /home/lynx/darkin_blade/cgal/mpfr/lib/libmpfr.so)

set(Boost_INCLUDE_DIR /home/lynx/darkin_blade/cgal/boost_1_76_0/boost)

• Boost_INCLUDE_DIR: Directory containing the boost/version.hpp file

然后进行编译

cmake -DCMAKE_TOOLCHAIN_FILE=/home/lynx/darkin_blade/cgal/toolchain.cmake -DWITH_CGAL_Core=FALSE -DCMAKE_CXX_FLAGS=-std=c++11 -DCGAL_test_cpp_version_RUN_RES=0 -DCGAL_HEADER_ONLY=TRUE -DWITH_CGAL_Qt5=FALSE /home/lynx/darkin_blade/cgal/cgal-5.3

根据具体情况修改目录

• ${CMAKE_INSTALL_PREFIX}: 默认/usr/local

将库导入Android

常见问题

1. 编译GMP时出现: could not find a working compiler, see config.log for details

clang路径不对

2. 安装CGAL时出现: "/usr/local/include/CGAL/Qt": No such file or directory.

默认安装路径/usr/local, make install需要sudo权限
