luvcview摄像头程序到Cortex A8的移植

背景：

luvcview摄像头程序到Cortex A8的移植

一、下载SDL源码包，交叉编译

#tar –xzvf SDL-1.2.14.tar.gz

#mv SDL-1.2.14 SDL-1.2.14-arm

#cd SDL-1.2.14-arm/

#cd /usr/local/

#sudo mkdirSDL-ARM-linux-gcc4.3.3

#./configure CC=arm-none-linux-gnueabi-gcc--target=arm-linux --host=arm-linux --prefix=/usr/local/SDL-ARM-linux-gcc4.3.3/--enable-static --disable-shared --disable-joystick --disable-cdrom--disable-esd --disable-nasm --enable-video-x11 --enable-video-fbcon --enable-video-opengl--enable-osmesa-shared --disable-arts --without-x --enable-debug -enable-loadso--disable-video-directfb

#make

#sudo make install

error:

./src/audio/dma/SDL_dmaaudio.c: Infunction 'DMA_WaitAudio':

./src/audio/dma/SDL_dmaaudio.c:166:error: impossible constraint in 'asm'

make: *** [build/SDL_dmaaudio.lo]Error 1

--disable-video-x11(去掉此项可以编译通过，按照上面编译不会出现此错误)

二、下载luvcview标准源码包，编译luvcview

#tar xzvf luvcview-2007-0512.tar.gz

#mv luvcview-2007-0512luvcview-2007-0512-arm

#cd luvcview-2007-0512-arm

#vim Makefile
