I want cross compile directfb for my dvevm
when I configure my directfb with
./configure --host=arm-linux --enable-devmem --disable-x11 --enable-multi \
--with-inputdrivers=keyboard --with-gfxdrivers=davinci \
--with-png=yes --with-freetypeyes
report with linux-fusion header not found
so where
I use configure --target=arm_v5t_le for my porting.
but with these error report:
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... Invalid configuration `arm_v5t_le': machine
`arm_v5t_le' not recognized
configure: error:
thanks Caglar,I use CC=xxx ... configuer and make ,all ok.
and I find your configure like this,
But if you want to use accelerated DaVinci video driver, you must use at
least directfb 1.2.0, or maybe git version. AFAIK, DaVinci support added
in 1.2.0 and stable release is missing some
thanks Niko,I found I make mistake in my xdcpaths.mak file:
I change it in these ,everything ok.
CE_INSTALL_DIR = /home/dummy/dvevm_1_00_00_27/codec_engine_1_00
...
XDAIS_INSTALL_DIR =/home/dummy/dvevm_1_00_00_27/xdais_5_00/packages
DSPLINK_INSTALL_DIR
1.first I cp whole examples tree to another place /home/dummy/tmp/examples;
2.then I change user.bld xdcpath.mak as your build_instructions
3.modify GPP makefile,and make,and failed when compile ceapp.c
could you tell me reasons maybe;
here is result:
I have no DSP expereince?So I wandered How and when DSP BIOS load and run.
I guessed two methods,
1.maybe linked when make .x64P.so when .x64P load ,BIOS load and run;
2.maybe are resident inside of Dsplink driver,when moduler insert,BIOS
load and run;
and how about .x64P load?
load when
I found they all have CERuntime_init() in app main.c
(dvevm_1_00_00_27\codec_engine_1_00\examples\apps\video_copy\singlecpu)
and server main.c
(dvevm_1_00_00_27\codec_engine_1_00\examples\servers\video_copy)
So my question is what they do in this function,same function in two
task(clientserver).
just be more patient,cause copy files need many times,more than 10 minutes
^-^

I just find in demos example,when you make install,just copy these two
ko from some directory to dest.I think these two modulor just be as
driver (/dev/cmem /dev/dsplink)
and no need to compile from source code,just copy to exec
directory.maybe in different applications,modify some parameters in
first of all,you should make sure your kernel have fb support,
then try mknod to create your fb device

I am a beginner,so I download dummy audio encoder example in which spraai6.pdf
when I build audcp_arm_linux_app,I got message audenc.h not find
I only know my davem install at /home/dummy/dvevm_1_00_00_27
no dsp bios installed,my host is RH9.0
but I want to try app build first
So I want to know
