[SOLVED] Unknown Symbol

thesequel · n00b Joined: 20 Mar 2010 Posts: 12

I'm running 2.6.34 (r4 I think... Not at my computer right now) and I can not figure out how to enable a symbol. The symbol I'm trying to enable is something like ir_hauppauge_new_table. I don't know how to enable symbols, I just use menuconfig to enable things that will select what I want. I hope that made sense.

This is needed by cx18 (dmesg says there's and unknown symbol ir_whatever). I tried looking for something in the kernel about IR but I did t find anything. I know that this symbol is in drivers/media/IR if it helps. Any ideas?

EDIT: Some output...

IIUC, you've found the symbol in the kernel source, but the cx18 application can't see it in the executing kernel binary. That means your kernel configuration doesn't cause that bit of the source to be compiled, or if it's compiled into a module, you've not loaded said module, or it's one of the deprecated symbols that don't get compiled unless you select a particular kernel option (CONFIG_UNUSED_SYMBOLS).

thesequel,

Symbols provided by one part of the kernel are used by other parts of the kernel. Sometimes by external modules that link against the kernel.
If you have and Unknown Symbol error, you are trying to load or link a module against a kernel that does not provide one of more of the symbols the new module needs.

In short, you need to select something else in make.menuconfig and rebuild your kernel.

If you provide the exact text of the error, so we know the missing symbol name, we can tell which part of the kernel you need to enable.
Tell us what you are doing and what you want to achieve - the context of the error is important too.

Looks as if you were not the only one having this problem

I'm not familiar with cx18 but have you installed the firmware (media-tv/cx18-firmware)?

@Manko10
The cx18 firmware is included in the kernel, I guess that package is an updated version. If I can't get this to work I'll try emerging that.

@NeddySeagoon
I'm not sure what you mean? I have to edit a file in that directory to enable it?

thesequel,

I guess you need to enable

Okay I'm going to try that, but how did you figure it out?

Hmm.. I don't have an IR section in Multimedia Support...

Here's what I'm seeing:

I'm going to try updating to kernel 2.6.36 since an IR section is supposed to show up in that one...

if i were you: create a new thread with cx-18 name (well the card or chip i don't know its real name) in title to drow others cx-18 users attention to your thread.

Best way to win.

thesequel,

I figured out your missing symbol problem from your
