nanogui: Thread: microwindows for eCos

I would like to build the microwindows for ecos. However, it is impossible to build the source code. The major problem is the file client.c. Do you have any information given to me?? Can you tell me the detail steps in order to build the microwindows for eCos?? Thanks for your help!! My email is ####@####.####

I have use the microwindows-0.89pre8 source codes to build the microwindows
for eCos.
The following are the steps I do:
1. Build the eCos using the template Compaq iPAQ PocketPC with the packages
choose all
2. cp Configs/config.ecos config
3. modify ECOS_PREFIX to my path in the file Arch.rules
4. make

The following are part of the output:

: I have use the microwindows-0.89pre8 source codes to build the microwindows
: for eCos.

This has been fixed in my preCVS sources, see below.

: client.c:608: structure has no member named '_regfdset'

Modify include/nano-X.h, line 817:

    fd_set    regfdset;
to
    fd)set    _regfdset;

Greg

Hi all!
I'm a french student and I'm trying to make microwindows working under eCos.
Here is the step i do .
ecosconfig new pc
After I'm searching in the ecos.ecc file the line "default donsole channel"
and il erase the "#" before "user value" and replace the 0 by a 2,
Then I'm searching startup type , I erase the "#" and replace ROM by floppy.
After that I type
ecosconfig template net
ecosconfig add mw
ecosconfig check
ecosconfig tree
make

After the compilation, I go to the directory with the source program and i
modify the file target.ld. I add a "0" in the length value. Then I run
i386-elf-gcc -g -D_ECOS -I ../ecos-pc/install/include helloNano.c -I
/home/amira3/Desktop/ecos/packages/services/gfx/mw/current/include/microwin/
-L ../ecos-pc/install/lib -Ttarget.ld -nostdlib
i386-elf-objcopy -O binary a.out
dd conv=sync if=a.out of=/dev/fd0

When i launch the program on the disk i got a black screen.
Can you help me?
Have you ever tried Microwindows under eCos? If yes, please send me some
informations.
Here is the program I try to launch



#define MWINCLUDECOLORS
#include <stdio.h>
#include "nano-X.h"

int main(int ac,char **av)
{
    GR_WINDOW_ID w;
    GR_EVENT event;

    if (GrOpen() < 0) {
        printf("Can't open graphics\n");
        exit(1);
    }
   printf("Can open graphics\n");
    w = GrNewWindow(GR_ROOT_WINDOW_ID, 20, 20, 100, 60,
        4, WHITE, BLUE);
    GrMapWindow(w);

    for (;;) {
        GrGetNextEvent(&event);
    }
    GrClose();
return 0;
}

Thank you in advance.
Antoine

Unfortunately, I have never run nano-X with eCos, although
others have, and the CVS should support it.  Look under
the contrib/ecos section or src/ecos sections to see applications
examples, they should help.  IIRC, seperate threads need to be
created for each "application", since they're all linked
together.

Greg
