problem compiling complex prog for uClinux

Hello all ..

I'm currently working on my grad project (i will post it here when i finish)

i have 2c35 board

i'm trying to run the mplayer program on uClinux ..

i disabled all unwanted options during the " ./configure " step

also i chose the compiler to be the nios-gcc .. from the buildroot guide provided by Mr. Hippo

when i type : " make" .. it starts compiling.. .. generates an executable file " codec-cfg" ... then it tries to execute it .. of course it makes an error .. as the linux cant execute a nios compiled prog..

can any1 help me in this problem.. i will be very gratefull.. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

about my project.. i am doing an IDCT H/W accelerator.. to reach the realtime requirements.. (still need to write its driver)

maybe MPLAyer is too complex .. does any1 have an an alternative idea .. of a simpler code for compiling??

Thanks in advance http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif

Yours,

Tarek

    You should post this on the uclinux forum.

    What do you want to do with your project?

    There are some audio related apps in uCLinux-dist.

    There are some interesting DSP related projects on blackfin uclinux forum. You should have a look at them. Some of them can be ported in Nios2, too.

    How did you do ./configure ?

    EDITED , removed configure option.

    video player, is a BIG project !!

    First, you (maybe) should develope the frame buffer device for your display , YUV or RGB?. You should try to display pictures or draw something.

    What happened with compile?

    Did you add the path of your cross compiler to $PATH env?
