编译适用于 linux arm64 的 GCC 时链接 .c 文件的 Makefile 链接器错误

问：

我正在使用 Linux WSL 上的 Android NDK 交叉编译 GCC，因为我的目标是 ARM64 Android。我需要一些 Android 兼容文件，例如（pytorch 需要）这些文件显然是在编译 GCC 时创建的。将来我可能还需要一个可以在 Android 上运行的 GCC 可执行文件。.solibgomp.so

这是我编写的用于编译 GCC 的构建脚本：

#!/bin/bash

export PATH="/home/ben/.local/bin:/opt/gradle/latest/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/"
BUILD_DIR=./build

GCC_DIR=`realpath gcc`

#CONF_FLAGS="--disable-shared"
CONF_FLAGS="--enable-shared --enable-static"

mkdir $BUILD_DIR

PREFIX=`realpath ./install/`
mkdir $PREFIX

echo "install directory: $PREFIX"

pushd $BUILD_DIR

export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/linux-x86_64
export TARGET=aarch64-linux-android

export API=23
export AR=$TOOLCHAIN/bin/llvm-ar
export CC=$TOOLCHAIN/bin/$TARGET$API-clang
export AS=$CC
export CXX=$TOOLCHAIN/bin/$TARGET$API-clang++
export LD=$TOOLCHAIN/bin/ld
export RANLIB=$TOOLCHAIN/bin/llvm-ranlib
export STRIP=$TOOLCHAIN/bin/llvm-strip

echo "Cleaning gcc directory via git clean"
pushd $GCC_DIR
git clean -f
popd

$GCC_DIR/configure --host $TARGET --prefix=$PREFIX $CONF_FLAGS
make

popd

我需要重新定义，否则我在makefile中出现语法错误，可能是因为在Windows的PATH中也定义了语法错误。 其他变量的定义如下：https://developer.android.com/ndk/guides/other_build_systemsPATHmake

./configure据我所知，似乎已经正确工作，但是当我运行时，过了一会儿，我收到以下错误：make

失败的命令是这样的：

我不确定发生了什么，因为它似乎正在尝试链接文件，我认为这不正常。我也不明白这些文件是如何涉及的，因为它们没有出现在命令中，目录也没有。 我不认为在 WSL 中编译是问题，尽管它以前引起了一些问题，但我认为我解决了它们。ld.cgcc/gcc/

我能做些什么来解决这个问题？
