交叉编译:添加符号时出错:文件格式错误

Question

我正在尝试交叉编译用于arm-v8的fdk-aac。

下面是我的构建脚本：

#!/bin/sh

NDK_HOME=/home/ubuntu/android-ndk-r12b

INSTALL_DIR=/home/ubuntu/compiled
SYSROOT=$NDK_HOME/platforms/android-16/arch-arm/
TOOLCHAIN=$NDK_HOME/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64
CROSS_PREFIX=$TOOLCHAIN/bin/aarch64-linux-android-

CC={$CROSS_PREFIX}gcc
CXX={$CROSS_PREFIX}g++
CPP={$CROSS_PREFIX}cpp
CXXCPP={$CROSS_PREFIX}cpp

./configure \
--prefix=$INSTALL_DIR \
--with-sysroot=$SYSROOT \
--host=aarch64 \
--enable-shared \
--with-pic=no \
CC="${CROSS_PREFIX}gcc --sysroot=$SYSROOT" \
CXX="${CROSS_PREFIX}g++ --sysroot=$SYSROOT" \
RANLIB="${CROSS_PREFIX}ranlib" \
AR="${CROSS_PREFIX}ar" \
STRIP="${CROSS_PREFIX}strip" \
NM="${CROSS_PREFIX}nm" \
LD="${CROSS_PREFIX}ld --sysroot=$SYSROOT" \
CFLAGS="-O2 $OPTIMIZE_CFLAGS --sysroot=$SYSROOT" \
CXXFLAGS="-O2 $OPTIMIZE_CFLAGS --sysroot=$SYSROOT"

#make
#make install

make和make install没有用，因为./configure失败了，错误消息要求我检查config.log

|   return 0;
| }
configure:3312: error: in `/home/ubuntu/fdk-aac-0.1.4':
configure:3314: error: C compiler cannot create executables

我不知道构建脚本的哪个配置是错误的。这是我第一次为ARM64交叉编译库……

我已经添加了这两个语句"SET(CMAKE_C_COMPILER "mips-linux-uclibc-gnu-gcc") SET(CMAKE_CXX_COMPILER "mips-linux-uclibc-gnu-g++")“和构建成功，可能会对您有所帮助。
