解决交叉编译arm-linux-gnueabihf/bin/ld: cannot find -*** 的类似报错

交叉编译报错：

/usr/lib/gcc-cross/arm-linux-gnueabihf/7/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lpcre
/usr/lib/gcc-cross/arm-linux-gnueabihf/7/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lnettle
/usr/lib/gcc-cross/arm-linux-gnueabihf/7/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lgnutls

类似这样的，问题是缺少交叉编译的依赖库（libpcre、libnettle、libgnutls）

解决方法：

wget https://sourceforge.net/projects/pcre/files/pcre2/10.37/pcre2-10.37.tar.gz
tar -xzvf pcre2-10.37.tar.gz
cd  pcre2-10.37/
./configure --host=arm-linux-gnueabihf \
            --prefix=$HOME/arm-libs \
            --disable-shared \
            --enable-static
make -j$(nproc)
make install
cd ..

wget https://ftp.gnu.org/gnu/nettle/nettle-3.6.tar.gz
tar -xzvf nettle-3.6.tar.gz
cd nettle-3.6

./configure --host=arm-linux-gnueabihf \
            --prefix=$HOME/arm-libs \
            --enable-shared \
            --enable-static \
            --enable-mini-gmp

make -j$(nproc)
make install
cd ..

wget https://gmplib.org/download/gmp/gmp-6.3.0.tar.xz
tar -xvf gmp-6.3.0.tar.xz
cd gmp-6.3.0

# 配置为 ARM 交叉编译
./configure --host=arm-linux-gnueabihf \
            --prefix=$HOME/arm-libs \
            --disable-shared \
            --enable-static

make -j$(nproc)
make install
cd ..

wget https://www.gnupg.org/ftp/gcrypt/gnutls/v3.8/gnutls-3.8.0.tar.xz
tar -xvf gnutls-3.8.0.tar.xz
cd gnutls-3.8.0

export PKG_CONFIG_PATH=$HOME/arm-libs/lib/pkgconfig
export PKG_CONFIG_LIBDIR=$HOME/arm-libs/lib


# 配置时需指定依赖库路径
./configure --host=arm-linux-gnueabihf \
            --prefix=$HOME/arm-libs \
            --disable-shared \
            --enable-static \
            --with-included-libtasn1 \
            --with-included-unistring \
            --without-p11-kit \
            CPPFLAGS="-I$HOME/arm-libs/include" \
            LDFLAGS="-L$HOME/arm-libs/lib"

make -j$(nproc)
make install
cd ..

然后重新make就可以解决问题
