In case someone's interested, I managed to make Microwindows
run on eCos.
It runs on PC synthetic Linux, and also on ARM PID board.
Since the board didn't have a real video interface, I used one of the
serial ports as the video interface on 115.2K.  :-(
I tested only the MWin API, but not Nano-X, though.

Hi,
Now I'm also port microwindows to ecos.
but I met a problem:
    I can't success to compile the file mwobjects.cc in directory
./mwin/mwobject/,
because the file is include a linux c++ file <algorithm> which can't be
found in ecos.
    You said you can run it in synthetic linux ,can you tell me how can you
resolve this problem.
    think you very much .

I think that this "algorithm" header file belongs to the STL, no link at all
with the Linux kernel but part of the standard C++ library. You could try
STLPort, a portable version of the STL but I do not know whether someone already
used it with eCos.

[ECOS] Microwindows on eCos

[Antoine.Amirault]

Hi,
I'm a student in a french engineering school and I'm trying to make  
microwindows work under eCos.
I'm doing these steps :

ecosconfig new pc
ecosconfig template net
ecosconfig add mw

After that I add the vga option with the configtool.
After that I compile a program but i got a black screen when i run it  
(on a PC).

Do you know why?
I've seen that there are some demos programs like ntetris in the  
configtool but I don't know how to run them (once I've checked them on  
the configtool).

And at least do you know if it is possible to write directly in the  
video memory to print a simple pixel for example.

I hope you can help me.
Best regards.
Antoine AMIRAULT

Okay, I've solved this one now.  Seems there is a bug in the vncviewer
program (at least in the x86 version).  eCos, microwindows and my
vncserver were all okay.

I haven't seen it for a while but I don't recall either of those problems. 
Certainly not (1) and I'm pretty sure not (2).

I'm going to make it public once the code has had a bit of a tidy up.
It should be ready early next week.

[ECOS] MicroWindows on eCos

[Chris Garry]

I've got my board running microwindows with my eCos VNC server
working as display, keyboard and mouse.  I'm running the eCos demo
application with just the Tetris thread included.

Would somebody who has seen this demo running (on the ipaq for
example) tell me if they saw the following problems.

(1)  When the app first starts up the cursor is while with a black outline -
however, as soon as I move the mouse the cursor changes to just
the black outline with the previously white parts now transparent.

(2)  The tetris window starts off with 'Nano-Tetris' written in white
on the title bar.  However, if I move this window the 'Nano-Tetris'
text changes from white to transparent.

Has anybody got any ideas about what is going wrong?

Thanks,
Chris

microwindows hasn't been ported to the synthetic target, sorry. Only 
(native) PC and iPAQ.

[ECOS] Microwindows on eCos

[fairy]

Hi, 

I'm trying to run microwindows on eCos on linux synthetic target but meet with some problems. 

Firstly, if I just make a linux synthetic target without any template, I cannot successfully add the microwindows package even thought I resolve all the conflicts. Many problems concerning the network files are reported in compling procedure. 

Then I add the microwindows package with elix template. It is successfully built but nothing happens when I run the executable file--it fails to start the window. (The test program is "demo.c" which I get from the microwindows package.) 

So I trace it with insight. I find that whenever it comes to 
ACCESS_PER_THREAD_DATA() 
"data->_nxSocket" will gain a great value 1919448176 where "data" is a structure to store datas from a thread. 

Problem occures when such "data->_nxSocket" is used as index of an array contains 16 elements: 
cyg_file *fp=desc[fd]; 

I have no idea what the problem is. Can anyone give me some advices? Thanks a lot!! 

Regards, 
fairy

It's created by magic using #define in the Makefiles.

Normal socket I/O over the loopback network.

The rest are used by the TCP/IP stack.

[ECOS] Microwindows on eCos

[宋宜叡]

Hi,
 In the microwidows-eCos over iPaq port, I have several questions:
    1. In ecos/nanox_thread.c (I assume it is the main nano-x server
thread),
        the code appears that nothing but the nanox_main() is called, but I
can't find its implementation anywhere.
    2. The original client/server IPC mechanism used in microwindows is Unix
domain socket+Sys V shared memory
        but what's the IPC mechanism used in the eCos port? TCP/IP socket?
    3. What is the job of sytem threads in the port?
 Or is there any documentations about that port?

Regards,
I-Jui Sung

I do not know why ecos does not have this file.
I just look at some BSD stuck, and it is defined
in sys/un.h. Maybe something is missing on the Ecos stack.

But, I believe you can easily change it to use AF_INET
socket types and use sockaddr_in. I do not know the reasons
why MicroWindows uses AF_UNIX socket family.

The name Microwindows is leading you to a wrong track. Microwindows is used 
for creating a graphics subsystem i.e. providing support for device 
independent graphics routines and graphic device drivers. The project comes 
in 2 flavors: NanoX and Microwindows. Based on the same libraries providing 
graphic primitives, NanoX provides a X-windows like API whereas 
Microwindows provides a more Windowslike API.

To my knowledge there is no generic graphics device layer in eCos yet. One 
can argue whether the graphics subsystem shall be part of the kernel, like 
in Microsofts Windows, or not, as with Unix running X-windows, where the 
X-server is just an ordinary server application providing its services to 
X-clients.

Microwindows is written that way, that you need to provide a module which 
implements low-level support for graphics i.e. provide a framebuffer device 
driver. If you have written this driver, you should be able to compile 
microwindows and link it to your ecos application.

BTW: Has anybody implemented framebuffer support for VGA cards for the i386 
target? I had a quick look on this, but initialization of the VGA card is 
quite cumbersome especially when running in protected mode. I could not 
find any good documentation on this.

Greetings,
Chris

Take a look at http://www.microwindows.org . There you'll find
everything about MicroWindows you want to know.

What is all this of microwindows?

  Maybe I'm interested on it. Does it allows you to use all the development

  Please, send me any reference to this matter.

Now I have turn off the compile option and got a success in runing win32 api
in ecos.
Thank you very much .
I have another problem in microwindows:
    I found the tcp/ip stack in ecos can't support nanox .The union
sockaddr_un in file "client.c" can't be found in ecos . So I can't get the
nano-x library .
Are there anybody had resolve this problem ?
Help me , thanks

You cannot. mwobject is a C++ wrapper for Microwindows ( Win32 API ). It 
uses STL, and STL is supported by Ecos at this time.

The good news is that you *do not need it*, unless you are a
C++ guru, and are sick and tired of the *boring* C based
Win32 API. MwObject only used by the Win32 API, and the NanoX
API does not use it.
