我正在尝试通过以下方式为Android交叉编译Linux PAM

`#!/bin/sh
# Linux-PAM/build.sh

INSTALL_DIR="`pwd`/out"

export
PATH="android/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/bin:$PATH"
export CROSS_COMPILER="$PATH:android/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/bin"
export SYS_ROOT="android/prebuilts/ndk/current/platforms/android-9/arch-arm" 
export CC="arm-linux-androideabi-gcc --sysroot=$SYS_ROOT"
export LD="arm-linux-androideabi-ld"
export AR="arm-linux-androideabi-ar"
export RANLIB="arm-linux-androideabi-ranlib"
export STRIP="arm-linux-androideabi-strip"

mkdir -p $INSTALL_DIR
./configure --host=arm-eabi --build=x86_64 --enable-shared --prefix=$INSTALL_DIR LIBS="-lc -lgcc"

make
make install`

输出给出静态构建的库.我想要共享库.如果我针对Linux进行编译,则默认情况下会构建共享库.但是对于Android,它是静态构建的. config.log文件具有以下内容

怎么了？

解决方法:

从命令行对Android进行交叉编译时,我遇到了类似的问题. iOS也很有趣.请参阅Autoconf邮件列表上的How To Configure for Android?.

我相信主机是不正确的.尝试：

./configure --build=`./config.guess` --host=arm ...

要么

./configure --build=`./config.guess` --host=arm-linux-androideabi ...

如果不是这样,您可以从config.log中发布完整结果(与共享对象测试有关的完整结果,而不是整个文件).

对不起,我不能再帮你了.我正在MacBook(为Android开发人员设置)上尝试Linux-PAM-1.1.8的交叉编译,但这是我的结果：

                 from pam_audit.c:12:
