一、下載SDL源碼包,交叉編譯
#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(去掉此項可以編譯通過,按照上面編譯不會出現此錯誤)
二、下載luvcview標准源碼包,編譯luvcview
#tar xzvf luvcview-2007-0512.tar.gz
#mv luvcview-2007-0512luvcview-2007-0512-arm
#cd luvcview-2007-0512-arm
#vim Makefile
