Editing the Header: gargoyle_header_footer

I wanted to put a link in the header to toggle on and off a frame. ie) like when you click on the gargoyle. I do NOT want to edit every single page.
However when I edit:
/usr/bin/gargoyle_header_footer
I get:
Bus Error when viewing the webpage.
I don't know if I can do what I want without being able to edit the header.
Please let me know how I can edit the header.
The frame I want to toggle on and off is:

You get an error because that's a binary file. The source code (in C) is in trunk/package/gargoyle/src/gargoyle_header_footer.c, if you check out the source from the SVN.
Implementing this functionality in C vs shell script is necessary because it dramatically improves performance (load time of each page is much faster).
You will need to recompile Gargoyle to make changes to that program.

I tried to compile on freeBSD after installing SVN from ports... There are a bunch of errors first 2 are missing files... the first missing file I moved to the same directory. The second missing file I couldn't find...
Code: Select all

You can't just do
Code: Select all
gcc gargoyle_header_footer.c -o gargoyle_header_footer
There are 2 major problems with this:
- You're compiling on your local system, so the binary will be incompatible with your router architecture. You need to cross-compile it.
- It has dependencies on other libraries
This is why the OpenWrt build system was created.
On linux, you can just checkout the SVN and type make [your architecture, usually "atheros-2.6" or "brcm-2.4"], and all the necessary stuff will be built. I don't know if this will work on BSD or not -- I do all my cross-compiling on Ubuntu Linux.
For more info on cross-compiling see a (very old!) tutorial I wrote, which can be found
here. Be warned, that's over 2 years old now, and refers to an ancient version of OpenWrt but the basic idea is the same.
