Hi all,

I'm trying to build uClinux from uClinux-20110210-ea2468_v091, on
xubuntu 12.04.
Doing...

# make CROSS_COMPILE=arm-unknown-linux-uclibc- xconfig
# make CROSS_COMPILE=arm-unknown-linux-uclibc-

eventually fails with...

ncurses.h exists, but is in /usr/include, not /usr/include/ncurses.
Isn't mconf.o to do with menuconfig?
I also did an initial make clean, still no luck.

Any idea how to fix this please?

Thanks,
David.

How about creating the directory and putting a symlink there that points back to the actual file? Or simply copy the entire file into the subdirectory.

cd /usr/include

Hi,

Is the NCurses to be used in your PC ? or is it suppose to be used in the ARM ?

/usr/include is directory for the PC's library headers, and not to be used for the ARM (or any target architecture) for cross compiling.

Find your ncurses in the EA unzipped / untarred directory:
bash# find -iname ncurses /your/EA/unzipped/dir

I'd recommend you to get one of those embedded linux book, or live with Linux to understand what you are trying to do with these commands.

Regards,
-daniel

Thanks all,

Created directory and copied several ncurses related files there,
/usr/include/ncurses/curses.h
/usr/include/ncurses/ncurses.h
/usr/include/ncurses/ncurses_dll.h
/usr/include/ncurses/unctrl.h

now compiles and creates uClinux and romfs.img

Regards,
David.
