Honored Contributorx264 for uclinux on DE2
Hi,
I want to add x264( encoder for h.264) to uclinux as an application. I follow uClinux-dist-test/Documentation/Adding-User-Apps-HOWTO . 1. add a line to user/Makefile , dir_$(CONFIG_USER_X264_X264) +=x264 2. add a line to misc section of config/config.in, bool 'x264' CONFIG_USER_X264_X264 3. mkdir ~/uClinux-dist-test/user/x264 4. put all the code in user/x264 dir, 5. create Makefile in user/hello dir, The Makefile ad follows: # Makefile include config.mak SRCS = common/mc.c common/predict.c common/pixel.c common/macroblock.c common/frame.c common/dct.c common/cpu.c common/cabac.c common/common.c common/mdate.c common/csp.c common/set.c common/quant.c encoder/analyse.c encoder/me.c encoder/ratecontrol.c encoder/set.c encoder/macroblock.c encoder/cabac.c encoder/cavlc.c encoder/encoder.c encoder/eval.c # Visualization sources ifeq ($(VIS),yes) SRCS += common/visualize.c common/display-x11.c endif # MMX/SSE optims ifeq ($(ARCH),X86) SRCS += common/i386/mc-c.c common/i386/dct-c.c common/i386/predict.c ASMSRC = common/i386/dct-a.asm common/i386/cpu-a.asm common/i386/pixel-a.asm common/i386/mc-a.asm common/i386/mc-a2.asm common/i386/predict-a.asm common/i386/pixel-sse2.asm common/i386/quant-a.asm common/i386/deblock-a.asm OBJASM = $(ASMSRC:%.asm=%.o) endif # MMX/SSE optims ifeq ($(ARCH),X86_64) SRCS += common/i386/mc-c.c common/i386/dct-c.c common/i386/predict.c ASMSRC = common/amd64/dct-a.asm common/amd64/cpu-a.asm common/amd64/pixel-a.asm common/amd64/mc-a.asm common/amd64/mc-a2.asm common/amd64/predict-a.asm common/amd64/pixel-sse2.asm common/amd64/quant-a.asm common/amd64/deblock-a.asm OBJASM = $(ASMSRC:%.asm=%.o) ASFLAGS += -Icommon/amd64 endif # AltiVec optims ifeq ($(ARCH),PPC) SRCS += common/ppc/mc.c common/ppc/pixel.c common/ppc/dct.c endif # VIS optims ifeq ($(ARCH),UltraSparc) ASMSRC += common/sparc/pixel.asm OBJASM = $(ASMSRC:%.asm=%.o) endif ifneq ($(HAVE_GETOPT_LONG),1) SRCS += extras/getopt.c CFLAGS += -DHAVE_GETOPT_LONG=0 else CFLAGS += -DHAVE_GETOPT_LONG=1 endif OBJS = $(SRCS:%.c=%.o) DEP = depend .PHONY: default fprofiled clean distclean install uninstall default: $(DEP) x264$(EXE) libx264.a: .depend $(OBJS) $(OBJASM) ar rc libx264.a $(OBJS) $(OBJASM) ranlib libx264.a x264$(EXE): libx264.a x264.o matroska.o $(CC) -o $@ x264.o matroska.o libx264.a $(LDFLAGS) x264vfw.dll: libx264.a $(wildcard vfw/*.c vfw/*.h) make -C vfw/build/cygwin checkasm: tools/checkasm.o libx264.a $(CC) -o $@ $< libx264.a $(LDFLAGS) common/amd64/*.o: common/amd64/amd64inc.asm %.o: %.asm $(AS) $(ASFLAGS) -o $@ $< .depend: config.mak rm -f .depend# Hacky - because gcc 2.9x doesn't have -MT $(foreach SRC, $(SRCS) x264.c matroska.c, ( echo -n "`dirname $(SRC)`/" && $(CC) $(CFLAGS) $(SRC) -MM -g0 ) 1>> .depend;) config.mak: $(wildcard .svn/entries */.svn/entries */*/.svn/entries) ./configure $(CONFIGURE_ARGS) depend: .depend ifneq ($(wildcard .depend),) include .depend endif SRC2 = $(SRCS) x264.c matroska.c# These should cover most of the important codepaths OPT0 = --crf 30 -b1 -m1 -r1 --me dia --no-cabac OPT1 = --crf 18 -b2 -m3 -r3 --me hex -8 --cqm jvt --direct spatial OPT2 = --crf 24 -b3 -m6 -r6 --me umh -8 -w -t1 -A all --b-pyramid --b-rdo --mixed-refs ifeq (,$(VIDS)) fprofiled: @echo 'usage: make fprofiled VIDS="infile1 infile2 ..."' @echo 'where infiles are anything that x264 understands,' @echo 'i.e. YUV with resolution in the filename, or avisynth.' else fprofiled: make clean mv config.mak config.mak2 sed -e 's/CFLAGS.*/& -fprofile-generate/;

So when I download the kennal to the board ,the application did not work. I had tried to modify "LDFLAGE= -W1 -elf2flt -lm -s" ,it was not useful. Pls give me some advice. Thanks!
