Another Relocation Truncated Error

[levone1]

Any help with this?
I'm just trying to build from source on Sailfish OS. Program is Ckermit.

Output is

Not sure how to attach files here. I can upload ckcpro.c file if helpful...

Thanks

It would be better to post the url of the repo where you got the whole source code from.

In the meantime, what do you get when you run these commands?

Sounds like a 32bit problem. What's your architecture?

If it is, I have more to add.

Any ideas?

[kbw]

Well, you didn't answer my question. You haven't shown what you're doing. I can't reproduce your error from the info in this thread.

So, if you want help, the please help us to help you by providing some information on what you're doing.

[levone1]

I thought your question was "what is your architecture", to which I replied "aarch64".

Did you have another question?

[levone1]

Sorry- I just noticed that my replay was not posted. I apologize... I don't know what happened. I know I wrote a reply, but not sure why it didn't post - maybe I lost connection and didn't realize it.

[kbw]

It would also help if you showed what you run and how (parameters for example).

[levone1]

Just following readme: clone/download, cd, and run "make linux"...

[salem c]

I downloaded it, but it won't even compile on x86_64 (Ubuntu 20.04)

I fixed that error with a patch. I don't remember where I got it, but it's for ckucmd.c file. The patch is:

debug(F101,"cmdconchk _IO_file_flags","",x);

Then the other error comes

[salem c]

OK, got it to compile with the patch.

Now some thoughts.
> ckcpro.o: in function `wart':

Looking at the source code, I see several interesting things.
1. It's auto generated.

/* WARNING -- This C source program generated by Wart preprocessor. */
/* Do not edit this file; edit the Wart-format source file instead, */
/* and then run it through Wart to produce a new C source file.     */

2. It's caused trouble before.

/*
  By late 1999, the big switch() statement generated from the following state
  table began choking even gcc, so here we extract the code from the larger
  states into static routines to reduce the size of the cases and the
  switch() overall.  The routines follow the state table; the prototypes are
  here.  Each of these routines simply contains the text from the
  corresponding case, but with return(-1) added in appropriate places; see
  instructions after the state table switcher.
*/

3. It's a huge function, 1800 lines long.
Maybe it needs more factoring of code into other functions.

4. The 'dest' variable it barfs on is only used once, and that's in a conditional.

#ifdef CALIBRATE
    if (dest == DEST_N)
      calibrate = 1;
#endif /* CALIBRATE */ 

Although it says it's auto-generated, you could try just editing it to remove those few lines and typing 'make linux' again.

[levone1]

Thank you.
Here's new output, seems like same error in 'skipbup', plus a few undefined refs...

I wonder of the issue is with my GCC... I'll mess around more. Thanks
