Hi All,
i have written make file to build own sample application using FFMPEG
static libraries, but i'm getting more than 200+ undefined reference errors
while compiling.
*Error exampls:*
./lib/libavcodec.a(mscc.o): In function `decode_init':
/home/bvittalprasad/ffmpeg_sources/ffmpeg/libavcodec/mscc.c:205: undefined
reference to `inflateInit_'
./lib/libavcodec.a(nellymoserdec.o): In function `nelly_decode_block':
>From error statements looks like static library once again looking for .c
files.
Makefile:
ROOT = .
SRC_DIR = $(ROOT)/src
INCLUDES = -I$(ROOT)/include
OBJECTS_BASE = $(ROOT)/obj
BIN_BASE = $(ROOT)/bin
LIBS = $(ROOT)/lib/libavdevice.a

#all
all: obj \

obj:$(OBJECTS)
lib:
bin: $(BIN_BASE)/transcoding
$(OBJECTS_BASE)/%.o: $(SRC_DIR)/%.c
$(CC) $(CFLAGS) $(INCLUDES) -c $< -o $@
$(BIN_BASE)/transcoding: $(OBJECTS)
$(LN) $(OBJECTS) $(LIBS) -lrt -o $@
please let me know how to link this static libraries.
