nanogui: Thread: MicroWindows & blackfin

Hi

I am trying to compile uClinux with Microwindows. I have taken the config
file for uClinux into consideration for selecting the options for
microwindows while"make menucofig". The kernel ic compiling fine, I get the
linux.dxe image.

I load the image onto the blackfin(EZ-LITE) board(using VDSP), the board
boots up fne and I get the shell. 

But when I give 

>nano-X &

I get an error : Bad command or file name.

 

When I capture the kernel messages while "make"ing, i get lots of errors in
between for microwindows, one of them being : cp:cannot stat 'nano-X' :file
not found.

This is because the other files required for creating this is not
created(prior errors are present).

 

I am using nisa-elf compiler for 2.4 uClinux kernel.

 

I am trying to remove these errors and get the nano-X server program created.

 

please tell me whether I am on the right track.

 

Moreover, what is the procedure to execute microwindows applications/demos on
the serial console.

I am using only minicom now, maybe when this becomes ok will go for a LCD.

Should i run nanowm, nteteris and nxclock om the background to run
microwindows application?

 

Please give me inputs regarding this.

 

Thank YOu

Warm Regards

Hi,

    Your 'nano-X' graphics server is not being made (check for that 
after every make in your 'microwindows/bin' directory). There can be 
several reasons for it. The simplest of which could be your microwindows 
config having a - 'LINK_APP_INTO_SERVER = Y'. This would not generate 
nano-X but things could still be fine. You can try running 
anyapplication like 'clock', 'world' or 'vnc' directly for testing.

    Secondly, check whether the microwindows 'config' file (ie; 
microwing/src/config) is being affected via changes thru 'make 
menuconfig' from uClinux-dist\ . Ultimately that config file determines 
the right options (like libraries and other device and linking options) 
to compile microwindows. Microwindows also has a src/xconfigure for the 
same purpose. If its config file is not getting affected by 
'./xconfigure' or a higher level 'make menuconfig' you'd have to modify 
it directly.

: The beauty is these errors are ignored and the kernel image is built

Yea thats true! :-) 
If you find out where this is done do let me know.

This needs MICROWIN library to be made. Enable it below:-

Until I see the prior errors list, it is hard to help.

Hi Greg 
Thanks for the input.
I have set FBVGA=N and those errors are eliminated.
But these undefined references are still there.

When -lc gives an error, that means your C library
isn't setup properly.

Find the microwindows config file that uclinux creates,
and make sure you've set FBVGA=N.  This is also the 
problem for the undefined _outw's below

You should grep and make sure these functions are in fact included
in your files.  Otherwise it suggests a linker problem...

Funny, PALINDEX is commented out in my header file,
include/device.h.  Check yours... there should be no instances
of PALINDEX in use, unless you're running an old version
of nano-X.

This is a C library issue, you may need to use stricmp instead.

I have included the header files for these functions properly. But still I am
getting the same. In fact I have even included the absolute path for these
header files.

I am using the microwindows which comes with uClinux distribution.
I am using uClinux-dist-20040513.tar for the kernel.
Does the problem lie there?
Also I am using nisa-elf-i386 rpm for the toolchain.
Kindly guide me.
 
Below is part of the include/device.h file which contains PALINDEX 

#if 0000
/* colors assumed in first 16 palette entries*/
/* note: don't use palette indices if the palette may
 * be reloaded.  Use the RGB values instead.
 */
#define BLACK		PALINDEX(0)		/*   0,   0,   0*/
#define BLUE		PALINDEX(1)
#define GREEN		PALINDEX(2)
#define CYAN		PALINDEX(3)
#define RED			PALINDEX(4)
#define MAGENTA		PALINDEX(5)
#define BROWN		PALINDEX(6)
#define LTGRAY		PALINDEX(7)		/* 192, 192, 192*/
#define GRAY		PALINDEX(8)		/* 128, 128, 128*/
#define LTBLUE		PALINDEX(9)
#define LTGREEN		PALINDEX(10)
#define LTCYAN		PALINDEX(11)
#define LTRED		PALINDEX(12)
#define LTMAGENTA	PALINDEX(13)
#define YELLOW		PALINDEX(14)
#define WHITE		PALINDEX(15)		/* 255, 255, 255*/
#endif


And it is not commented for me. Am I using an outdated version for this?
What can I do for it? Should I go for another distribution?

Thanks again for the suggestions.

Warm regards
Marshia

Hi Marshia,

Microwindows has been ported to work on the blackfin platform.
Please go to http://blackfin.uclinux.org/projects/uclinux533. The code
is available on the CVS HEAD.
