Hey

I have to make a finel work for school.

1 of my tasks is making ncurses on a BF537 whit ucLinux. And watch it bij the serial interface.

I can compile it just for my pc but not for the Blackfin.

it is just a simple hello world:

#include <ncurses.h>

int main()

{

initscr(); /* Start curses mode */

printw("Hello World !!!"); /* Print Hello World */

refresh(); /* Print it on to the real screen */

getch(); /* Wait for user input */

endwin(); /* End curses mode */

return 0;

}

I compile like this:

bfin-uclinux-gcc hello.c -lncurses

i got 1 error

hello.c:1:21: error: ncurses.h: No such file or directory

What do i have to now?

the toolchain is only the toolchain. it doesnt come with any libraries. you can either build up ncurses and such by yourself, or use the uclinux-dist to build it up.

read this page for more information:

Hey

When i follow the site and i do this:

bfin-linux-uclibc-gcc -O2 hello.c -o hello -isystem /home/jasper/Desktop/uClinux-dist-2008R1.5-RC3/staging/usr/include -L/home/jasper/Desktop/uClinux-dist-2008R1.5-RC3/staging/usr/lib

I got this:

/tmp/ccRMBuqi.o: In function `_main':

hello.c:(.text+0xa): undefined reference to `_initscr'

hello.c:(.text+0x16): undefined reference to `_printw'

hello.c:(.text+0x2c): undefined reference to `_wgetch'

hello.c:(.text+0x32): undefined reference to `_endwin'

collect2: ld returned 1 exit status

you added search paths but then dropped the actual linkage to ncurses ...

i just added -lncurses. Like this

bfin-linux-uclibc-gcc hello.c -o hello -lncurses -isystem /home/jasper/blackfin/uClinux-dist/staging/usr/include -L/home/jasper/blackfin/uClinux-dist/staging/usr/lib

i added also a text file with my errors.

he doenst say anymore that ncurses.h doenst exist but this is the most of all ¨failed to merge target specific data of file¨

at the and there are a lot of warnings.

note: my pad is a bit different

thanks
