Pd on Toshiba Portege 4010?.................
by chun lee 03 Apr '04

03 Apr '04

hello: Is anyone running Pd on Toshiba Portege 4010 preferably with Linux? I am looking for some general feedback, in particular the following issues 1. is it ok with Linux(fedora), or any other idstribution? 2. any hardware/performance problem? 3. well, if no one is using this particular model, any feedback on Portage or just Toshiba machines in general will also help. Many thanks Yours CHUN

hia, some kind person at #dataflow suggested me to check the right version of gcc for compiling pidip, right now im loosing it here: pdp_mp4live~.cpp: In function `void pdp_mp4live_ipaddr(t_pdp_mp4live*, t_symbol*)': pdp_mp4live~.cpp:254: warning: int format, t_int arg (arg 3) pdp_mp4live~.cpp:254: warning: int format, t_int arg (arg 4) pdp_mp4live~.cpp:254: warning: int format, t_int arg (arg 5) pdp_mp4live~.cpp:254: warning: int format, t_int arg (arg 6) pdp_mp4live~.cpp: In function `void pdp_mp4live_process(t_pdp_mp4live*)': pdp_mp4live~.cpp:524: invalid conversion from `t_int*' to `int*' pdp_mp4live~.cpp: In function `void pdp_mp4live_input_0(t_pdp_mp4live*, t_symbol*, float)': pdp_mp4live~.cpp:547: invalid conversion from `t_int*' to `int*' make[1]: *** [pdp_mp4live~.o] Error 1 make[1]: Leaving directory `/root/pd/externs/pidip-0.12.13/modules' make: *** [pdp_pidip_all] Error 2 my ./configure.ac looks like this: PDP_PIDIP_VERSION="0.12.13" PD_DIR=/root/pd PDP_DIR=/root/pd/externs/pdp-0.12.3 #FFMPEG_SOURCE_DIR=/SOURCES/ffmpeg MPEG4IP_SOURCE_DIR=/root/mpeg4ip-1.0 PDP_STREAMING_OBJECTS=/root/pd/extra PDP_PIDIP_LIBS="$PDP_PIDIP_LIBS -lbz2 -lz -ldl -lmp3lame -logg -lvorbis -lvorbi$PDP_PIDIP_INCLUDES="-I$PD_DIR/src -I. -I$PDP_DIR/include -I../include" and this was part of the output of the ./configure --enable-mpeg4ip looking for pd sources (required) ... ok. looking for pdp sources (required) ... ok. looking for mpeg4ip sources (required) ... ok. gracias por cualquier pista, /alejo (mp4live cause i plan to use a quicktime streaming server) -- http:// Zona Desmilitarizada |||||||| http://kolab.da.ru/ ||||||||||||||||||| ||| http://co.lab.cohete.net/egs/index.html ||||| ||||||||Da size of switz|||||| http://www.egs.edu |||||||||||||||||||||||||||||||||||||||||||||||||

OK, so I looked at the makefile in externals/build/linux and this is my new makefile (which seems to work): -----------makefile-------------------------------- LDFLAGS = -Wl,-export_dynamic -shared LIB = -lc -lm INCLUDE = -I. -I/usr/local/include BIN_DIR = ../general LIB_DIR = lib EXT = pd_linux STRIP = strip --strip-unneeded -R .note -R .comment CC = gcc LINUXCFLAGS = -fPIC -DPD -DUNIX -O2 -funroll-loops -fomit-frame-pointer \\ -Wall -W -Wshadow -Wstrict-prototypes \\ -Wno-unused -Wno-parentheses -Wno-switch sphere: $(CC) $(LINUXCFLAGS) $(INCLUDE) -o $(LIB_DIR)/sphere~.o -c sphere~.c $(CC) $(LDFLAGS) -o $(BIN_DIR)/sphere~.$(EXT) $(LIB_DIR)/sphere~.o $(LIB) chmod a-x \"$(BIN_DIR)/sphere~.$(EXT)\" $(STRIP) sphere~.$(EXT) rm -f \"$(LIB_DIR)/sphere~.o\" fftbin: $(CC) $(LINUXCFLAGS) $(INCLUDE) -o $(LIB_DIR)/fftbin~.o -c fftbin~.c $(CC) $(LDFLAGS) -o $(BIN_DIR)/fftbin~.$(EXT) $(LIB_DIR)/fftbin~.o $(LIB) chmod a-x $(BIN_DIR)/fftbin~.$(EXT) $(STRIP) $(BIN_DIR)/fftbin~.$(EXT) rm -f $(LIB_DIR)/fftbin~.o ---------------------------------------------------- So, my external loads fine, but when I invoke it I get: Segmentation fault which is an error I cant really use to debug, other then my my perform function is using too many (t_int *w) elements, or Im not asking for enough elements in my dsp function. Also I get too many inlets. I want one signal rate inlet that takes signal and bang, like snapshot, and another that takes in control rate floats (int). The dsp_add function and its relation to the perform functions (t_int *w) has always confused me. Could someone help me to get this straight in my head?

Frank Barknecht hat gesagen: > Do you really need link in librt, libjack and libasound? No, I just copied some of the makefile stuff from the pd/src directory OK, so the -c option lets me build my external, but now I cant load it. im sure I didnt code something right, but I dont know what to do with this error message /home/wade/pd/general/fft-bin~.pd_linux: /home/wade/pd/general/fft-bin~.pd_linux: ELF file\'s phentsize not the expected size Below here lies my external code: fft-bin~.c-------------------------------------- #include <m_pd.h> /*-------------------------------------------------------*/ /*fftbin~ */ /* A tool to extract specific bins from the output of */ /* fft~.
