Linux Pam 创建静态库而不是共享库

Question

我正在尝试交叉编译 Linux PAM对于 android 的方式如下

`#!/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`

输出给出了静态构建的库。我想要共享库。如果我为 linux 编译，它会默认构建共享库。但对于 Android，它是静态构建的。 config.log 文件具有以下内容

configure:3581: arm-linux-androideabi-gcc --sysroot=android/prebuilts/ndk/current/platforms/android-9/arch-arm -v >&5

出了什么问题？

我在从命令行为 Android 交叉编译时遇到了类似的问题。 iOS 也很有趣。参见 How To Configure for Android?在 Autoconf 邮件列表上。

我认为 host 不正确。尝试:

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

或

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

如果不是这样，您能否发布 config.log 的完整结果(与共享对象测试相关的完整结果，而不是整个文件)。

抱歉，我无法为您提供更多帮助。我正在我的 MacBook 上尝试交叉编译 Linux-PAM-1.1.8(它是为 Android 开发人员设置的)，但这是我的结果:

In file included from pam_modutil_private.h:14:0,
                 from pam_audit.c:12:
./include/security/pam_modutil.h:53:20: fatal error: shadow.h: No such file or directory
compilation terminated.
make[2]: *** [pam_audit.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

$ pwd

$ find . -iname shadow.h
