Title: Native sdk
Post by: djtreble on September 29, 2004, 06:34:46 pm: Downloaded http://mirror1.pdaxrom.org/zgcc-3.3.2.img (http://mirror1.pdaxrom.org/zgcc-3.3.2.img) .

Instructions:

Quote
Quick install instructions: Put the file in /home/root and reboot

Sounds too good to be true and sure enough nothing happened.

or manually mount the file to /opt/arm/3.3.2

#mount /home/root/zgcc-3.3.2.img /opt/arm/3.3.2/
mount: /home/root/zgcc-3.3.2.img is not a block device (maybe try '-o loop')

#mount -o loop /home/root/zgcc-3.3.2.img /opt/arm/3.3.2/
mount: you must specify a filesystem type

#mount -o loop -t cramfs /home/root/zgcc-3.3.2.img /opt/arm/3.3.2/
mount: wrong fs type

What next?

Sorry if I'm being really dense.

Cheers

Thanks for telling me everyone!

Title: Native sdk
Post by: djtreble on October 04, 2004, 08:33:21 am: Nope, still not working. Here's what I have tried and worked out:

Mounting Zazz's zsdk (https://www.oesf.org/forums/index.php?showtopic=3490&hl=zsdk) is really easy and as far as I could tell worked, short of me exporting a few paths.

The only think I didn't like is that the compiler is configured as an arm cross compiler for arm, if that makes any sense. Functionally it should be identical to a native compiler, it just might take a bit more work configuring things to be built with it.

The binutils, gcc and gcc-headers packages in feed2 all seem work, I just couldn't find the space to install them. I tried to symlink my /opt/ directory to a directory on my SD card, but ipkg just trashed the symlink and installed to internal flash. I need to work out how to install them on my SD card.

I'm pretty sure the zgcc-3.3.2.img is a version of the above packages and would be ideal if I could work out how to mount it. Anyone?

Cheers

Dan

Post by: djtreble on October 04, 2004, 03:11:27 pm: Got it with a bit of hex editing. http://mirror1.pdaxrom.org/zgcc-3.3.2.img (http://mirror1.pdaxrom.org/zgcc-3.3.2.img) is actually a gziped cramfs image. So to mount it we need to do something like this...

#mv zgcc-3.3.2.img zgcc-3.3.2.img.gz
#gunzip zgcc-3.3.2.img.gz
#mkdir -p /opt/arm/3.3.2
#mount -o loop,ro -t cramfs /mnt/card/zgcc-3.3.2.img /opt/arm/3.3.2

And to check it's pathed and 'working'
#gcc -v

Thank god for that!

Now if only the file had been named zgcc-3.3.2.cramfs.gz , I wouldn't have had nearly as much fun!

Post by: djtreble on October 09, 2004, 12:34:41 pm: For rc5

http://mirror1.pdaxrom.org/rc5/zgcc-3.3.2.img (http://mirror1.pdaxrom.org/rc5/zgcc-3.3.2.img)

is NOT gzipped.

it wants mounting to a slightly different directory though

#mkdir -p /opt/arm/3.3.2-vfp
#mount -o loop,ro -t cramfs /mnt/card/zgcc-3.3.2.img /opt/arm/3.3.2-vfp

Hope this helps someone.

Cheers

Post by: Zumi on October 19, 2004, 04:58:48 pm: I have some problem however with the IPK making. The SDK tutorial on the pdaXrom site says:
Quote
# Compile/Install the program there using, make DESTDIR=ipkg_tmp install
This usually gives me an error. With hnb (http://hnb.sf.net) it says it can't find the program called "install" and gnuplot (http://www.gnuplot.info) doesn't install in that directory, only in the system, as it would normally. (I wanted to recompile them with the new VFP thingie)
Please, I want to contribute IPKs, but I can't pack them if they don't install nicely in this dir.

I searched for the "install" program and the package called coreutils has it on my Debian system. Any suggestion how to get it in pdaXrom. (I'm using RC5 native SDK)

I tried to crosscompile things with SDKs before, but I got too many errors at the configure scripts and so... So I tried the native SDK and it's as easy to use as to compile programs for my desktop Linux system. Give it a go if you felt similar before!

Post by: pgas on October 20, 2004, 03:14:24 am: I have started a new thread (https://www.oesf.org/forums/index.php?act=ST&f=73&t=7810) for install and coreutils.

As a general note you will often need other small tools that are not in the sdk
or in the base rom.

Compiling various thing I found configure and install script required for instance:

make (of course)
file
diffutils
coreutils (install program)

Post by: pgas on October 22, 2004, 08:02:26 am: Though I didn't try, i think so. At least matchbox header files are included.

1. When I try to compile little program:

Code: [Select]
#include int main() { Â return 0; }
there are a lot of errors

2. When I try to compile this program:

Code: [Select]
#include int main() { Â return 0; }
compiler couldn't find file "iostream"

Post by: pgas2 on October 22, 2004, 11:58:16 am: 1.
try gcc -I/opt/arm/3.3.2-vfp/armv5tel-cacko-linux/include/freetype2/ -o main main.c

2.
#include <iostream> is a c++ notation if i am not mistaken
try with g++
