<h1>libnl库 编译</h1>
<p>1.git下载opensource源码，此版本为3.2.x</p>
<pre><code>git clone git://github.com/tgraf/libnl.git
</code></pre>
<p>2.编译</p>
<pre><code>cd libnl
</code></pre>
<p>配置Makefile：</p>
<p>glibc版本：</p>
<pre><code> ./configure --host=mips-linux-gnu --prefix=${PWD}/_install
</code></pre>
<p>uclibc版本：</p>
<pre><code>./configure CFLAGS="-muclibc -O2" CPPFLAGS="-muclibc -O2" LDFLAGS="-muclibc -O2" --host=mips-linux-gnu --prefix=${PWD}/_install
</code></pre>
<p>然后 ：</p>
<pre><code>make；make install
</code></pre>
<hr />
<h1>libopenssl 库编译</h1>
<p>1.git下载opensource源码</p>
<pre><code>git clone git://git.openssl.org/openssl.git
</code></pre>
<p>切换到 1.1.0版本</p>
<pre><code>cd openssl
git checkout origin/OpenSSL_1_1_0-stable -b 1.1.0
</code></pre>
<p>2.编译</p>
<p>第一步：</p>
<p>配置Makefile：</p>
<pre><code>./Configure linux-generic32 shared -DL_ENDIAN --prefix=${PWD}/_install --openssldir=${PWD}/_install
</code></pre>
<p>第二步：</p>
<p>修改makefile</p>
<p>glibc版本:</p>
<p>默认 glibc版本 直接执行第三步</p>
<p>uclibc版本：</p>
<pre><code>vi Makefile
</code></pre>
<p>CFLAG 和 SHARED_LDFLAGS 添加-muclibc</p>
<pre><code>CFLAG= -fPIC -DOPENSSL_PIC -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DL_ENDIAN
-O3 -fomit-frame-pointer -Wall
...
SHARED_LDFLAGS=
</code></pre>
<p>改成：</p>
<pre><code>CFLAG= -fPIC -DOPENSSL_PIC -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DL_ENDIAN
-O3 -fomit-frame-pointer -Wall -muclibc
...
SHARED_LDFLAGS= -muclibc
</code></pre>
<p>第三步：</p>
<pre><code>make CC=mips-linux-gnu-gcc RANLIB=mips-linux-gnu-ranlib LD=mips-linux-gnu-ld MAKEDEPPROG=mips-linux-gnu-gcc PROCESSOR=MIPS
make install
</code></pre>
<hr />
<h1>编译 wpa_suppliant</h1>
<p>1.git下载opensource源码，此版本为2.7</p>
<pre><code>git clone git://w1.fi/hostap.git
</code></pre>
<p>2.编译
第一步：</p>
<pre><code>cd hostap/wpa_supplicant
cp defconfig .config
</code></pre>
<p>第二步：修改.config 添加 libnl openssl 库路径配置</p>
<pre><code>vi .config
</code></pre>
<p>在文件末尾添加如下</p>
<p>glibc版本：</p>
<pre><code>CC=mips-linux-gnu-gcc
PWD-libnl = /your/install/path
PWD-openssl = /your/install/path
CFLAGS += -I/$(PWD-libnl)/_install/include/libnl3/
LIBS += -L/$(PWD-libnl)/_install/lib
LIBS_c += -L/$(PWD-libnl)/_install/lib
LIBS_p += -L/$(PWD-libnl)/_install/lib
CFLAGS += -I/$(PWD-openssl)/_install/include/
LIBS += -L/$(PWD-openssl)/_install/lib
LIBS_c += -L/$(PWD-openssl)/_install/lib
LIBS_p += -L/$(PWD-openssl)/_install/lib
CONFIG_LIBNL32=y
CONFIG_EAP_FAST=y
CONFIG_TLS=openssl
</code></pre>
<p>uclibc版本:</p>
<pre><code>CC=mips-linux-gnu-gcc
PWD-libnl = /your/install/path
PWD-openssl = /your/install/path
CFLAGS += -I/$(PWD-libnl)/_install/include/libnl3/
LIBS += -L/$(PWD-libnl)/_install/lib
LIBS_c += -L/$(PWD-libnl)/_install/lib
LIBS_p += -L/$(PWD-libnl)/_install/lib
CFLAGS += -I/$(PWD-openssl)/_install/include/
LIBS += -L/$(PWD-openssl)/_install/lib
LIBS_c += -L/$(PWD-openssl)/_install/lib
LIBS_p += -L/$(PWD-openssl)/_install/lib
CFLAGS += -muclibc
LDFLAGS += -muclibc
CONFIG_LIBNL32=y
CONFIG_EAP_FAST=y
CONFIG_TLS=openssl
</code></pre>
<p>第三步:</p>
<pre><code>make -j4;
</code></pre>
<p><strong>注意</strong>：编译出来的库和应用都是not stripped，可以用 mips-linux-gnu-strip 命令节省空间</p>
<p><em>例子：</em></p>
<pre><code>mips-linux-gnu-strip wpa_supplicant
</code></pre>
