Ubuntu系统下交叉编译harfbuzz

一、参考资料

在ubuntu中，交叉编译harfbuzz，freetype，opencv（包括WITH_QT），并移植到linux开发板

二、交叉编译harfbuzz

重要说明：因为harfbuzz和freetype相互依赖，所以要么先编译harfbuzz（不带freetype），然后编译freetype（带harfbuzz），然后编译harfbuzz（带freetype）；要么就反过来，先编译freetype。

1. 下载harfbuzz源码

下载harfbuzz：https://github.com/harfbuzz/harfbuzz

下载并解压源码。

tar -xvzf harfbuzz-10.2.0.tar.gz
cd harfbuzz-10.2.0

2. 设置环境变量

设置交叉编译工具链的bin路径：

export PATH=/home/yoyo/360Downloads/toolchains/arm-linux-gnueabihf/bin:$PATH

3. cmake 编译（不带freetype）

cmake  -DCMAKE_BUILD_TYPE=Release \
-DBUILD_SHARED_LIBS=ON \
-DCMAKE_INSTALL_PREFIX="/home/yoyo/360Downloads/harfbuzz-10.2.0/arm32_install" \
-DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc \
-DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++ \
-DHB_HAVE_FREETYPE=OFF \
-DHB_HAVE_ICU=OFF \
-DHB_HAVE_GLIB=OFF ..

输出示例：

yoyo@ubuntu:~/360Downloads/harfbuzz-10.2.0/build$ cmake  -DCMAKE_BUILD_TYPE=Release \
> -DCMAKE_INSTALL_PREFIX="/home/yoyo/360Downloads/harfbuzz-10.2.0/arm32_install" \

> -DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++ \
> -DHB_HAVE_FREETYPE=OFF \
> -DHB_HAVE_ICU=OFF \
> -DHB_HAVE_GLIB=OFF ..
