OpenHarmony Linux 环境 SDK 使用说明(进阶--依赖库的解决方法)

​ 我们在移植三方库的时候，很多库是有依赖的。面对这种情况我们应该如何处理。下面以libzip为例讲解下如何为ohos编译带依赖的库。

编译libzip

源码准备

下载最新版本的 libzip 和 xz （libzip 是可以依赖 xz 项目中的 liblzma.so 的）

#解压源码
ohos@ubuntu20:~/openHarmony/ohos_libzip$ ls
libzip-1.9.2.tar.gz  xz-5.4.1.tar.gz
ohos@ubuntu20:~/openHarmony/ohos_libzip$
ohos@ubuntu20:~/openHarmony/ohos_libzip$ tar -zxf xz-5.4.1.tar.gz
ohos@ubuntu20:~/openHarmony/ohos_libzip$ tar -zxf libzip-1.9.2.tar.gz
ohos@ubuntu20:~/openHarmony/ohos_libzip$ ls
libzip-1.9.2  libzip-1.9.2.tar.gz  xz-5.4.1  xz-5.4.1.tar.gz

完成。

大家可以自己试试 zstd openssl 等库的依赖实现。
