hostapd移植(2.6版本爲例)

Hostapd的移植，依賴：libnl openssl  

下載地址：

　　Hostapd-2.6：http://w1.fi/releases/hostapd-2.6.tar.gz

　　Libnl:             http://www.infradead.org/~tgr/libnl/files/

　　Openssl:     https://www.openssl.org/source/old/1.0.1/

 

Libnl： 交叉編譯 (選擇的版本是libnl-1.1.tar.gz)

解壓安裝包，建一個__install文件夾用來保存安裝的庫文件

# mkdir __install

#./configure CC=arm-fullhan-linux-uclibcgnueabi-gcc --prefix=$PWD/__install --host=arm

#make & make install

能夠看到__install/lib/ 下面有生成的libnl動態庫

 

若是但願能生成靜態庫，對lib/Makefile作以下修改：

#vim lib/Makefile

 

 修改好的 lib/Makefile

保存退出，make& make install 就能夠生成libnl.a 靜態庫了。

 

 

 

 

Openssl交叉編譯：(選擇的版本是openssl-1.1.1.tar.gz)

 解壓安裝包，建一個__install文件夾用來保存安裝的庫文件

# mkdir __install

# ./config no-asm no-shared no-async --prefix=$PWD/__install

注意：若是不加入no-async，會出現如下錯誤：

       ./libcrypto.a(b_sock.o): In function `BIO_gethostbyname':

b_sock.c:(.text+0x4a8): warning: gethostbyname is obsolescent, use getnameinfo() instead.

./libcrypto.a(async_posix.o): In function `ASYNC_is_capable':

async_posix.c:(.text+0x48): undefined reference to `getcontext'

./libcrypto.a(async_posix.o): In function `async_fibre_makecontext':

async_posix.c:(.text+0x7c): undefined reference to `getcontext'

async_posix.c:(.text+0xec): undefined reference to `makecontext'

./libcrypto.a(async.o): In function `async_fibre_swapcontext':

async.c:(.text+0x28c): undefined reference to `setcontext'

collect2: ld returned 1 exit status

make[1]: *** [apps/openssl] Error 1

make[1]: Leaving directory `/test/hostapd_test/openssl-1.1.1'

make: *** [all] Error 2

 

修改Makefile

 #PLATFORM=linux-x86

PLATFORM=linux-armv7

#CROSS_COMPILE

CROSS_COMPILE=arm-fullhan-linux-uclibcgnueabi-

刪除全部的 -m32 -m64選項

保存退出，make clean

Make & make install

在__install 裏面就能夠看到靜態庫了：

 

 

 

Hostapd的編譯：（選擇的版本是hostapd-2.6.tar.gz）

解壓hostapd-2.6安裝包，進入

# cp defconfig .config

修改Makefile

CC=arm-fullhan-linux-uclibcgnueabi-gcc

CFLAGS += -I /test/hostapd_test/libnl-1.1/__install/include

LIBS += -L /test/hostapd_test/libnl-1.1/__install/lib -lnl

CFLAGS += -I /test/hostapd_test/openssl-1.1.1/__install/include

LIBS += -L /test/hostapd_test/openssl-1.1.1/__install/lib -lcrypto -lssl

BINDIR := ./__install/bin

LDFLAGS += -lpthread

LDFLAGS += -lm

 

注意：

Libnl 和 libopenssl 爲上述步驟編譯生成的。此處的包含路徑能夠選擇絕對路徑。

若是不加入LDFLAGS += -lpthread ，LDFLAGS += -lm 兩個選項會出現以下錯誤：

install/lib/libnl-1.1.a(utils.o): In function `nl_prob2int':

libnl-1.1.1/lib/utils.c:392: undefined reference to `rint'

collect2: ld returned 1 exit status

保存；

#make & make install

就能夠在__install/bin 下面生成hostapd命令了。

 

 

 注意：由於libnl和libopenssl都是編譯成靜態庫形式，因此hostapd在開發板上能夠直接運行，不須要將libxxx.so 拷貝到/lib/下面。

WiFi模塊常常用到hostapd啓軟AP，換個平臺，又得從新編譯一遍，因此本身整理下，下次找也方便。借鑑了上述文章，還請不吝賜教，若侵權，聯繫即刪。
