How to cross-compile Linux APP for WL500GP

[fillmore]

My WL500Gp's firmware : 1.9.2.7-7f (2006-11-06)

I want to cross-compile Linux application like enhanced-ctorrent for running on my WL500GP.

How should I do ?

I can install enhanced-ctorrent by using http://ipkg.nslu2-linux.org/feeds/unslung/wl500g/enhanced-ctorrent_dnh2.2-6_mipsel.ipk

package. But i can't find the source code of this ipk and i don't know how to build this package.

I want build this package by myself,so I want to know how to cross-compile enhanced-ctorrent source code for WL500GP.

Enhanced-ctorrent's Source code : http://www.rahul.net/dholmes/ctorrent/ctorrent-1.3.4-dnh2.2.tar.gz

Thanks a lot.

I succesfully compiled some stuff with this tutorial on Suse 10.2:

http://www.macsat.com/BuildEnvironment.php

The tutorial is a little outdated. You have to change the address of cvs.sourceforge.net to nslu.cvs.sourceforge.net and you also need to export the paths with:
export PATH=$PATH:/opt/brcm/hndtools-mipsel-uclibc/bin:/opt/brcm/hndtools-mipsel-linux/bin

Then if you are lucky just do "make". Otherwise you'll have to edit the Makefile to change the paths to the right directories.

This articale only describles Native compilation ?

I don't understand how to cross-compile enhanced-ctorrent on my linux PC.

I try dioby's method.

Steps :

1.Download GPL_ToolChain.zip From ASUS web site.
2.tar zxvf opt.tar.gz
3. Now my directories :
/opt/brcm/opt/hndtools-mipsel-linux
/opt/brcm/opt/hndtools-mipsel-linux-3.0
/opt/brcm/opt/hndtools-mipsel-linux-3.2.3
/opt/brcm/opt/hndtools-mipsel-uclibc
/opt/brcm/opt/hndtools-mipsel-uclibc-0.9.19
/opt/brcm/opt/hndtools-mipsel-uclibc-3.2.3

4. cd /opt
cvs -z3 -d:pserver:anonymous@nslu.cvs.sourceforge.net:/cvsroot/nslu co unslung
5. Now my directories add : /opt/unslung

6. cd /opt/unslung
make directories
make ipkg-utils
make enhanced-ctorrent

7. Now my directories add :
/opt/unslung/builds/enhanced-ctorrent
/opt/unslung/builds/libstdc++
/opt/unslung/builds/openssl
/opt/unslung/builds/zlib

8.make enhanced-ctorrent-ipk
Error Now :

tar: unknown option `--format=ustar'
Try `tar --help' for more information.
make: *** [/opt/unslung/builds/enhanced-ctorrent_dnh2-1_mipsel.ipk] Error 1


How should i do ? Or any steps go wrong ?

Thanks a lot

Have you downloaded the Asus sources GPL_1927.zip?

Have you downloaded the Asus sources GPL_1927.zip?


WL500gp directory : GPL_ToolChain.zip ,GPL_WL-500gP_1972.zip

opt directory is only in GPL_ToolChain.zip.

I don't use GPL_WL-500gP_1972.zip.

As you can see the problem is here:

tar: unknown option `--format=ustar'

Try to find where the line is located and remove it.

I copy the cross-compiled enhanced-ctorrent to WL500GP.

When I run on WL500gp, there's an error.


enhanced-ctorrent : can't load library 'libstdc++.so.5'.

What should I do?

I just want to know the precedure of building http://ipkg.nslu2-linux.org/feeds/unslung/wl500g/enhanced-ctorrent_dnh2.2-6_mipsel.ipk this file by myself.

I want to produce the same file with enhanced-ctorrent_dnh2.2-6_mipsel.ipk.

svn co http://svn.nslu2-linux.org/svnroot/optware/trunk optware
export OPTWARE_TARGET=ddwrt
make directories
make toolchain
make packages


can't work directly

When i make toolchain, there are lots of errors.

I still try to figure it out.

[fillmore]

optware/oleg/toolchain/buildroot => buildroot-svn-17310.tar.gz (download by "make toolchain")

Is this buildroot-svn version right ?
And how to configure it's .config file ? It uses the default .config file.

If i use the default .config file, there are lots of errors.

[diody]

optware/oleg/toolchain/buildroot does not exist. Try to edit and change the path to:

optware/oleg/cross/stable/

I recommend to use
tar 1.14
bash 2.05
autoconf-1.9
gcc 4.1.1

It helps a lot.

I change my OS from RedHat 9.0 to Fedora Core 6.

It can work directly without any errors.

Thanks you
