当我运行configure时，它告诉我它无法链接到libffi它并与之编译。
这很奇怪，因为它已经安装了，而且我不知道应该做什么，因为所有需要的软件包都已安装。
命令：
bash configure \
--enable-option-checking=fatal \
--disable-warnings-as-errors \
--enable-headless-only \
--with-jvm-variants=zero \
--build=x86_64-unknown-linux-gnu \
--host=i686-linux-android \
--target=i686-linux-android \
--with-cups-include=/usr/include \
--with-devkit=$ANDROID_DEVKIT \
--with-extra-ldflags=-L/root/libffi-3.4.2 \
--with-debug-level=release \
--with-boot-jdk=/root/jdk-17.0.1
这是输出：

It is recommended that you use --openjdk-target instead.

你说“[ libffi] 已安装”，但配置脚本另有声明：
配置：错误：找到 libffi 但无法使用它进行链接和编译。您也许可以通过运行“sudo apt-get install libffi-dev”来修复此问题。
很可能libffi没有安装在标准位置，例如它可能位于/opt/lib或下/usr/local/lib，并且您尚未更新链接器配置以包含目标目录，或者您尚未安装开发包libffi-dev。
