用以下命令编译成功后没有libnl-3.so.200
./configure --prefix=$(pwd)/sss \
--host=arm \
--sysconfdir=/etc \
--disable-static &&
make CC=arm-linux-gnueabihf-gcc

对， 否则就是不识别的指令集了.
晕哥,我是想学习怎样交叉编译,所以想自己编译libnl-3.2.25
离线
libnl-3.so.200 是一个软链接吧，实际应该指向 libnl-3.so
你看下 libnl-3.so 是否存在。
没有一个.so的文件,我觉下配置关,下面的说明我看不明白
NOTE
There have been some changes starting with 3.2 regarding where and how libnl
is being installed on the system in order to allow multiple libnl versions
to be installed in parallel:
- Headers will be installed in ${prefix}/include/libnl3, therefore
you will need to add "-I/usr/include/libnl3" to CFLAGS
- The library basename was renamed to libnl-3, i.e. the SO names become
libnl-3.so., libnl-route-3.so, etc.
- libtool versioning was assumed, to ease detection of compatible library
versions.
If you are using pkg-config for detecting and linking against the library
things will continue magically as if nothing every happened. If you are
linking manually you need to adapt your Makefiles or switch to using
pkg-config files.

我试了一下，明明有生成文件！
我的怎么没有,你能写下你的步骤吗

执行这个x86编译：
./configure --prefix=/usr \
--sysconfdir=/etc \
--disable-static &&
make
晕哥,我的和你那样操做,有错误,是什么问题呢,网上查都查不到

刚才用办公电脑再试了一次, 仍然非常正常:
wget https://www.infradead.org/~tgr/libnl/files/libnl-3.2.25.tar.gz
tar xvf libnl-3.2.25.tar.gz
./configure --prefix=/usr --sysconfdir=/etc --disable-static
make -j3
晕哥,终于可以了可能我的libnl有问题,下面是用的gcc编译吗?如果要编译到v3s上用,要怎么编译?是在make后面跟着CC=arm-linux-gnueabihf-gcc吗

晕哥,我下面的编译方法是不是交叉编译了,可以在v3s里用了吗?
https://www.infradead.org/~tgr/libnl/files/libnl-3.2.25.tar.gz
tar zxvf libnl-3.2.25.tar.gz
cd libnl-3.2.25
./configure --prefix=$(pwd)/aaa \
--host=arm-linux-gnueabihf \
--sysconfdir=/etc \
--disable-static &&

make install
