nano-x user program

Question

Hello all, i tryed the nano-x, nanowm, nxview and i would like to write some user programs for nano-x windows. But when i wanted to compile the program from http://www.microwindows.org/programmingintro1.html (sample.c)   #define MWINCLUDECOLORS# include &lt;stdio.h&gt;# include "nano-X.h"  int main(int ac,char **av) {     GR_WINDOW_ID w;     GR_EVENT event;      if (GrOpen() &lt; 0) {         printf("Can't open graphics
");         exit(1);     }      w = GrNewWindow(GR_ROOT_WINDOW_ID, 20, 20, 100, 60,         4, WHITE, BLUE);     GrMapWindow(w);      for (;;) {         GrGetNextEvent(&amp;event);     }     GrClose();     return 0; } ---------------------------------   it finished with error that the compiler dont know the "nano-X.h" and it is true, in ...nios2/toolchain-build/build/nios2/include is not exist. I tryed to copy from /user/microwin/src/include, but this header need some next headers and c. source code.   How is possible to use nano-x api for user programming ? Could you advice me ? I was surprised and i would like to try it :)   Thank you for your answer.   Jan Naceradsky, Czech republic

I included the program in the uiCLinux/user/ directory tree and did the necessary settings to have it shown in "make menuconfig" (see the Wiki on how to do this.)

I successfully used this Makefile:

# Makefile for displaytext application

EXEC = displaytext

OBJS = $(EXEC).o

SOURCE = $(EXEC).c# LIBADD = -L $(STAGEDIR)/usr/lib

INCLUDEDIRS = -I $(STAGEDIR)/usr/include/microwin

LDLIBS += -l nano-X

LDLIBS += -l pthread

all: $(EXEC)

# $(EXEC): $(OBJS)

$(EXEC):

@echo ------ "@:" $@

@echo ------ INCLUDEDIRS: $(INCLUDEDIRS)

@echo ------ EXEC: $(EXEC)

@echo ------ OBJS: $(OBJS)

@echo ------ LDFLAGS: $(LDFLAGS)

@echo ------ LDLIBS: $(LDLIBS)

@echo ------ CC: $(CC)

@echo ------ LIBADD: $(LIBADD)

@echo ------ STAGEDIR: $(STAGEDIR)

$(CC) $(LDFLAGS) -o $@ $(SOURCE) $(INCLUDEDIRS) $(LIBADD) $(LDLIBS)

romfs:

$(ROMFSINST) /usr/bin/$(EXEC)

clean:

-rm -f $(EXEC) *.elf *.gdb *.o

Hello,

thank you for reply, but i am not just familier with make file etc... so i tryed to change some source code in /user/microwin/src/demos/nanox for example i copy the tutorial sample to demo.c and run MAKE,

but the demo in romfs/bin was the same ... i found that demo is in

microwin/src/bin and obj file in

microwin/src/obj

and the final file in romfs/bin is the same.

How can i force to make again demo from demo.c ? (or any other file - demo2.c, dashdemo.c etc. -

when i set

[*] other demo in menuconfig, i can test in niosII embedded evaluation kit and they run okay :)) )

Thank you very much.

Hi Michael,

i tryed your way ... make new directory /user/displaytext, created displaytext.c and insert to makefile in /user and to Kconfig new lines according to description for add new user application

and use your makefile, but no object file displaytext.o and no displaytext for running in uclinux was created.

For me it was be best to change only for example demo2.c and it compile and use in my application.

How can i compile only one file with gcc in /user/microwin/src/demos/nanox/demo2.c ?

Thankyou.

I supose "user" is located within your ucLinux-dist directory (besides vendors) and the "Makefile" is in uClinux-dist/user/microwin/src/demos/nanox

AFAIR: if the make system is set up correctly:

"make user/microwin/src/demos/nanox"

Hi,

it looks very simple, but it works for example for cpu

/>make user/cpu/cpu

it compile cpu okay, but

/>make user/microwin/src/demos/nanox

make:Nothing to be done for 'user/microwin/src/demos/nanox'.

/>make user/microwin/src/demos/nanowm

make:Nothing to be done for 'user/microwin/src/demos/nanowm'.

/>make user/microwin/src/demos/nanox/demo2

nano-X.h: No such file or directory

error ......

.....

Make: Error1

I would need to run or create makefile, where would be set directories well or how to run the all compilation again :(.

Could you advise me ?

Thank you.

Jan
