disassembling an .so file

Hello

As the topic says, I need to disassemble a .so component object file so I can fix it, no source. Sorry I'm not a linux wizz. How do I do this?

John

Do you understand assembler ? And have hours I guess to spend ?

Unless of course you're adapt and reverse engineering.

This thread might shed some light on things, but I don't think it is going to be an easy task.

Google would probably be a much better resource.

I ran this command in ~/linuxcnc-dev/rtlib$You''ll have to look at the manpage for objdump for the options.

And this was the output:

Thank you, I should have been a little clearer in what I was asking for. What I wanted was to go from a .so object file back to some kind of source or sudo code file that had all of the manual and pin definitions intact. I have actual gotten that data using the strings -w command on the file and saving the output to a text file. The only problem is it isn't formatted and requires that you have a pretty good understanding of how to build a hal component to get everything right.

I looked and couldn't find it, including web searches. My search skilled may leave a little to be desired. The component is thcenable.so and is not part of the standard LinuxCNC distributions. It is marked with a GPL2 rights marker.

From a download off of the web. No source files attached.

I know it will not work as is for me because it was allegedly compiled on an i386 version of linux and I run an AMD-64 version. I actually just wanted to experiment with it, my controller does the same thing using stock hal components. The place sells a re branded LinuxCNC control system. They will not knowingly release any source code even though every source file I've seen is marked as being GPL (including the thcenable one after putting it through the strings -w command). This similar to the Path Pilot situation only the owner will not comply with the GPL terms.
