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 ############################### spcaview Makefile############################## INSTALLROOT=$（PWD） +CC=arm-none-linux-gnueabi-gcc+CPP=arm-none-linux-gnueabi-g++INSTALL=installAPP_BINARY=luvcviewBIN=/usr/local/binSDLLIBS = $（shell sdl-config--libs）SDLFLAGS = $（shell sdl-config--cflags+SDLLIBS =-L/usr/local/SDL-ARM-linux-gcc4.3.3/lib -lSDL+SDLFLAGS =/usr/local/SDL-ARM-linux-gcc4.3.3/include#LIBX11FLAGS +=-I/home/ema/dvsdk/ti-dvsdk_dm3730-evm_4_02_00_06/omap35x_graphics_sdk_4.00.00.01/gfx_dbg_es2.x/freedesktop/kdrive/usr/X11R6_SGX/include-L/home/ema/dvsdk/ti-dvsdk_dm3730-evm_4_02_00_06/omap35x_graphics_sdk_4.00.00.01/gfx_dbg_es2.x/freedesktop/kdrive/usr/X11R6_SGX/lib#X11_LIB += /home/ema/dvsdk/ti-dvsdk_dm3730-evm_4_02_00_06/omap35x_graphics_sdk_4.00.00.01/gfx_dbg_es2.x/freedesktop/kdrive/usr/X11R6_SGX/libVERSION = 0.2.1 #WARNINGS = -Wall # -Wundef -Wpointer-arith-Wbad-function-cast # -Wcast-align -Wwrite-strings-Wstrict-prototypes # -Wmissing-prototypes-Wmissing-declarations # -Wnested-externs -Winline-Wcast-qual -W # -Wno-unused# -Wunused +CFLAGS +=-I/home/ema/dvsdk/ti-dvsdk_dm3730-evm_4_02_00_06/omap35x_graphics_sdk_4.00.00.01/gfx_dbg_es2.x/freedesktop/kdrive/usr/X11R6_SGX/includeCFLAGS += -DUSE_SDL -O2 -DLINUX-DVERSION="$（VERSION）" -I$（SDLFLAGS） $（WARNINGS）CPPFLAGS = $（CFLAGS） OBJECTS= luvcview.o color.outils.o v4l2uvc.o gui.o avilib.o all: luvcview #carefully:"+" means that need to amend or need to add.
