im trying to upgrade some of pd's special features:

pdp # ./configure --enable-mmx --enable-pwc --enable-pf checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking how to run the C preprocessor... gcc -E checking for egrep... grep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking m_pd.h usability... yes checking m_pd.h presence... yes checking for m_pd.h... yes checking for sin in -lm... yes checking linux/videodev.h usability... yes checking linux/videodev.h presence... yes checking for linux/videodev.h... yes checking for main in -lgslcblas... yes checking for main in -lgsl... yes checking for png_read_image in -lpng... yes checking for XOpenDisplay in -lX11... yes checking for XvPutImage in -lXv... yes checking for lqt_decode_video in -lquicktime... yes checking for glXSwapBuffers in -lGL... yes checking for SDL_Init in -lSDL... yes target is linux_mmx_pf used configure options: --enable-mmx=yes --enable-quicktime=yes --enable-v4l=yes --enable-pwc=yes --enable-sdl=yes --enable-x=yes --enable-xv=yes --enable-glx=yes --enable-gsl=yes --enable-png=yes --enable-debug=no --enable-pf=yes configure: creating ./config.status config.status: creating Makefile.config config.status: creating bin/pdp-config config.status: creating include/pdp_config.h

so far all seems ok but when i do make && make install i lose it here:

dp/../pd/src -o pdp_v4l.o -c pdp_v4l.c pdp_v4l.c: In function pdp_v4l_bang': pdp_v4l.c:628: error:PDP_IMAGE_YV12' undeclared (first use in this function) pdp_v4l.c:628: error: (Each undeclared identifier is reported only once pdp_v4l.c:628: error: for each function it appears in.) make[2]: *** [pdp_v4l.o] Error 1 make[2]: Leaving directory /home/sid/pd/pdp/libpdp/modules/image_io' make[1]: *** [pdp12] Error 2 make[1]: Leaving directory/home/sid/pd/pdp/libpdp' make: *** [linux_mmx_pf] Error 2

thnks for any clue. /a
