hi,

i'd like to compile a small ansi c program for dd-wrt. i think it's not possible to compile directly on the router. what is to do for cross compiling this?

Ok. Here is a simple helloword example:

1. The helloworld.c source
Code:
#include <stdio.h>

int main ( void ) {
        printf( "Hello world!\n" );
}


2. Get and unpack the toolchain in your homedir
Code:
cd ~
wget ftp://ftp.dd-wrt.com/sourcecode/toolchains.x86.debian.sp1.tar.bz2
tar -jxf toolchains.x86.debian.sp1.tar.bz2


3. Add the path to your cross-compiler executable to your path environment variable and compile helloworld.c
Code:
PATH=~/toolchains/4.1.0-uclibc-0.9.28/bin:$PATH mipsel-linux-uclibc-gcc helloworld.c -o helloworld


4. Check if its correctly compiled with the cross-compiler
Code:
file helloworld
helloworld: ELF 32-bit LSB executable, MIPS, version 1 (SYSV), dynamically linked (uses shared libs), not stripped


5. Finally, transfer the helloworld binary file to your router, set the executable bit and run it.

Tested with Ubuntu 6.06.1 LTS.



To build DD-WRT from source see The DD-WRT v23 SP1 Final building guide.

Ok that's good to compile a simple file!
But in the case where I need compile a more complex project!
Normally (with linux) you make :
Code:

./configure
make


Where do I indicate that is a cross compilation? Where do I specify the executable is not for my pc but for the router?

Thanx for any answer...

DD-WRT sucks. Why? See http://www.bitsum.com/about-ddwrt.htm

montesq, I'd recommend you take look at OpenWrt's buildroot and X-Wrt's webif^2. DD-WRT's build system is horrible and a piece of crap.

Go and test OpenWrt, perheps you like it. With OpenWrt's buildroot crosscompilation is very easy. F.e. if you like to build your own OpenWrt images you just have to check out svn branch and run:

Code:
make menuconfig
make


Takes about an hour or so and you have ready to use images in the bin/ folder.


I've already "played" with openwrt, and it's true that compiling kernel sources is easier but that's not my problem!!
I only want to compile an application (e.g. openssh) and add it in the firmware of dd-wrt, it's why I need know how to cross-compile with the procedure : ./configure & make ...

Anybody want to humor me and help me? I want to compile a script I have for GCC on the DDWRT. it's a tutorial script as I am pretty dang new to the Linux comunity. Anyway. I didn't understand the post a couple of posts above and would like to know what I need to do to get the script working on the DD-WRT. I tried compiling in under normal GCC and it simply won't run on my router. What do I need to do? I would really appreciate SIMPLE instructions. Right now I have GCC installed(On my linux box) and the toolchain that was in the link downloaded(To my linux box)

My Linux Box is running CentOS 4.2

Thanks in Advance

P.S. Oh yea. the script: http://sage.mc.yu.edu/kbeen/teaching/networking/resources/tcp-server.cc

The procedure as described by 'sagichnict04' worked for me with a few corrections:

step 2: The toolchain is located at: ftp://ftp.dd-wrt.com/others/sourcecode/toolchains/

The toolchain is used to make a binary which runs on your router. This is necessary due to different processor architectures.

When using a Makefile, look for an option called 'CROSS':
CROSS = mipsel-linux-uclibc-

Then run 'make'.

Tested with Mandriva Spring 2008.1 Free.

I used it to compile a newer version of p910nd (0.92) because ipkg has version 0.7.

I have successfully compiled and tried DD-WRT from trunks.
Now I would like to make some modifications, for example adding some files, for example in the /etc directory.
How to do that?

I have tried to add an "hello world" file directly to src/router/mipsel-uclibc/target directory, but the image created didn't work.
I also have tried to add it to src/router/misc directory, but looks like that directory is not taken in consideration during the building process.

Any suggestion is appreciated.
Thank you.

Guys this toolchain is for x86-64 machines. And how should I compile on simple x86 i386 machine?
