iLiad First HelloWorld tutorial, a n00b primer First Hello World Tutorial, a n00b primer

[mind]

(cross posted from iRex forum)
NOTE: this is just and intro. For more please refere to Adam's posts or other threads.

You need a linux distro, a usb key, the shell account actived and the dropbear or a shell on iliad.
Download the last toolchain: http://developer.irexnet.com/pub/Toolchain/ .
Uncompress it and move to the directory /oe-sdk-20070607085328/usr/local/arm/oe/bin . Then open a Terminal and type:

core2duo bin # echo '#include <stdio.h>
int main(){ printf("Hello World\n"); }
' | ./arm-linux-gcc -x c -o hello -

Note this is just a printf, compiled with a pipe. You can as well make a .c file with the code and compile from that file. (./arm-linux-gcc -o hello hello.c)
The copy hello to your usb key, start your iLiad with usb key inserted, login with ssh, cd to /mnt/usb and run ./hello. This should be print "Hello World"
And that's all folks.

Good post.

I really need to start collecting and organizing all the information about porting apps to the iLiad...

I thought the same
Just as I got some time, I'll try to build the toolchain for amd64 and maybe try some nicer programming ^^
Thank again for your tutorials, you'are a sort of inspiration :P

Wow, I don't think I've ever inspired anyone before...

[jharker]

Heck, you inspire me all the time!

I was also able to compile the gtk-helloworld, but I still need to figure out how to do the refresh. Did anyone released the source of some port? This would accelerate the process, instead of lurking in the iRex source.

@Adam
What's about a wiki? Or we can update the wiki that already exists (Antartica's one, if I 'm not wrong).

The wiki is mobileread one. And updating/adding pages on how to program for the iliad would be great :-).

If anyone volunteers for it...

And about the refresh: you can peruse the information in

http://projects.mobileread.com/iliad...0061203-2.diff

It's how the patched libX11 does it. The information on the refresh is in fact based on some early post of scotty1024.

Best regards, Antartica.

Many thanks, it worked. When I have some time, I'll post a "Hello World" in gtk and then copy-paste on wiki.

Hi,
I tried to build my first app but failed. The attached file is the screent of the source code and the error message by gcc. Please help. Thanks.

I used Fedora Core 8 on a VMWare.


[Edit]
I solved the problem. It's the problem of VMWare. In VMWare, when I type quotation mark, I have to type twice to make it show on the screen. I don't know why. So I edited the "hello.c" in my Windows XP, then transferred it to Linux under VMWare. It works.

[mind]

I did a gtk version too, but I don't have time to search for it, cause university. Anyway it suffices to modify a little bit the hello-gtk and then to link the correct libs.

[siman007]

Does anybody have an example of how to build a GTK version of hello world? I have taken the example gtk hello world (http://bo.majewski.name/bluear/gnu/GTK/plain/) , I get all the way to the make but it falls over a) its using gcc not the arm version and b) it cannot find the gtk libs and I cannot work out how to link to them.
Thanxs for any help

[mind]

Sorry, in the end I didn't write anything. This is cause I don't have time to program, and even to use iLiad! (I prefer plain paper for my mathematical study, and use iLiad for pleasure lectures.)
I don't remember now the correct libs to link, but maybe I still have the binary. If you need it, let me know.
Regards, Gil.

Hi Siman007,

I'm using the scratchbox environment to compile for my Iliad. (see sticky post at the top of this forum). It takes the arm compiler without asking questions :-)

For gtk I use the tutorial at: http://library.gnome.org/devel/gtk-t...able/x111.html
gcc helloworld.c -o helloworld \
`pkg-config --cflags gtk+-2.0`\
`pkg-config --libs gtk+-2.0`

echo `pkg-config --libs gtk+-2.0` will show you the linker flags. The flags depend on the libraries installed, for me it expands to:

-L/usr/local/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -lglib-2.0

Happy coding!

That's similar to what I did. Thanks for providing this information.
