使用独立工具链为android构建squid时未定义的引用错误

Question

我正在尝试为android构建鱿鱼-3.5.24。我正在使用android-ndk-r10e进行构建。这是我的环境。基于此：https://gist.github.com/nddrylliog/4688209

#!/bin/sh

# I put all my dev stuff in here
export DEV_PREFIX=$HOME/Documents

# Don't forget to adjust this to your NDK path
export ANDROID_NDK=$HOME/Android/android-ndk-r10e

export CROSS_COMPILE=arm-linux-androideabi

# I chose the gcc-4.7 toolchain - works fine for me!
export ANDROID_PREFIX=$DEV_PREFIX/toolchain/arm-linux-androideabi-4.8

# Apparently android-8 works fine, there are other versions, look them up
export SYSROOT=${ANDROID_PREFIX}/sysroot

export CROSS_PATH=${ANDROID_PREFIX}/bin/${CROSS_COMPILE}

# Non-exhaustive lists of compiler + binutils
# Depending on what you compile, you might need more binutils than that
export CPP=${CROSS_PATH}-cpp
export AR=${CROSS_PATH}-ar
export AS=${CROSS_PATH}-as
export NM=${CROSS_PATH}-nm
export CC=${CROSS_PATH}-gcc
export CXX=${CROSS_PATH}-g++
export LD=${CROSS_PATH}-ld
export RANLIB=${CROSS_PATH}-ranlib

export PATH=$PATH:$ANDROID_PREFIX/bin
export PATH=$PATH:${SYSROOT}/usr/lib
# This is just an empty directory where I want the built objects to be installed
export PREFIX=${SYSROOT}

# Don't mix up .pc files from your host and build target
export PKG_CONFIG_PATH=${PREFIX}/lib/pkgconfig

# You can clone the full Android sources to get bionic if you want.. I didn't
# want to so I just got linker.h from here: http://gitorious.org/0xdroid/bionic
# Note that this was only required to build boehm-gc with dynamic linking support.
export CFLAGS="${CFLAGS} --sysroot=${SYSROOT} -I${SYSROOT}/usr/include -I${ANDROID_PREFIX}/include"
export LDFLAGS="${LDFLAGS} -L${SYSROOT}/usr/lib -L${ANDROID_PREFIX}/lib"

./configure --host=${CROSS_COMPILE} --with-sysroot=${SYSROOT} --prefix=${PREFIX} --cache-file=squid.cache "$@"

configure成功完成，我运行了make。在编译过程中，我得到了以下错误：

我认为这个错误与链接器无法定位libstdc++或libstdc++--v3有关，但是这些库存在于已经提供给ld的sysroot/usr/lib中。

我尝试过将库直接链接到-lstdc++--v3和-lstdc++，但这似乎在配置上与gcc混在一起。

目前在我的智囊团，谁能指出我的正确方向？

更新：将我的ndk更新为android-ndk-r13b，并且错误持续存在。

Answer 1

您应该尝试使用独立工具链。它们专为使用NDK与非NDK构建系统而存在。他们将完成如何传递您所需的所有标志的工作；您只需调用clang++即可。

您还应该更新NDK。r10现在三岁了。独立的工具链直到最近才运行得那么好(r12，但您最好升级到r13)。
