Print Page - Local Zaurus Compile Of An Ncurses Application

Greetings!

I am trying to compile a program written in C++, (no STL or Templates), that uses ncurses for the UI. The program was originally written in Windows under Bloodsheds Dev-C++.

Ncurses was supplied using a DEV Package for Bloodshed, called pdcurses2.6.

Well, my application doesn't compile and I think it is because I am not linking to the ncurses library, because most of the errors are undefined reference to ncurses calls :

IE. undefined reference to 'wattr_on'
undefined reference to 'waddch'
etc.

So, for starters, here is my ZGCC.SH file :

export GCC_EXEC_PREFIX=/mnt/cf/.zgcc/lib/gcc-lib/arm-linux/2.95.2/
export COMPILER_PATH=/mnt/cf/.zgcc/bin:/mnt/cf/.zgcc/lib/gcc-lib/arm-linux/2.95.2/
export CPATH=/mnt/cf/.zgcc/
export LIBRARY_PATH=/mnt/cf/.zgcc/lib/:/mnt/cf/.zgcc/lib/gcc-lib/arm-linux/2.95.2/:/lib/:/home/QtPalmtop/lib/
export CPLUS_INCLUDE_PATH=/mnt/cf/.zgcc/g++-3/
PATH=/mnt/cf/.zgcc/bin:$PATH
export PATH
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/cf/.zgcc/lib
export LD_LIBRARY_PATH
TMAKEPATH="/mnt/cf/.zgcc/tmake/lib/sharp-onboard/"
export TMAKEPATH
ln -sf /lib/libc.so.6 /usr/lib/libc.so
ln -sf /lib/libm.so.6 /usr/lib/libm.so
ln -sf /mnt/cf/.zgcc/bin/libstdc++-3-libc6.1-2-2.10.0.so /home/QtPalmtop/lib/libstdc++-libc6.2-2.so.3

Anybody know what's going on?

Thanks,

Andres

I searched google about linking ncurses and found a G++ example. All I needed to do was add '-lncurses' and now it works.

Case closed!

I can't get ncurses in my program to work. I need some help. I don't even know what the problem is anymore. I've only been programming for 2 years too, so bare with me.

I am trying to get my roguelike (http://roguebasin.t-o-m-e.net/index.php/Main_Page) game running on my Zaurus. It's simple C/C++ game that I wrote in school. Currently, it is using ncurses for the graphicsal user interface, but I was using windoes console before and switched. It will compile with 'g++ -lncurses *.c -o test', and will run with './test', but only my debugging text is printing, not the ncurses portions of the game. My debugging text is printed to the display using standard cout, not ncurses.

Well, maybe ncurses isn't installed on the Z? I found the following package, 'libncurses_5.0_arm.ipk' and installed it but even after a recompile ncurses still doesn't work.

So, I am starting to think maybe it has to do with how I am using ncurses in my code. I hope in posting it someone with ncurses experience can easily recognise anything that I might be doing in error. As a last resort, I might make my Z-port B&W only (couts only) or maybe find an ncurses program that runs on the Zaurus and mimic its method of ncurse programming. But, I'm not conviced entirely that ncurses is working properly on my Z. Hopefully, this can be resolved easily.

Here's my code in its primeval form.
