problem installing rdiff-backup

[worthlutz]

I'm trying to set up a MicroCore server on an old computer to catch backups.  I am trying to use rdiff-backup but cannot get it to install.  The build dies with the following error:

/tmp/tcloop/gcc/usr/local/bin/../lib/gcc/i686-pc-linux-gnu/4.6.1/include-fixed/limits.h:169.61: fatal error: limits.h: No such file or directory
compilation terminated.

But limits.h does exist in that directory!

What am I doing wrong?

Thanks,
Worth

Have you actually checked what line 169 of the file in question contains?

Code: (bash) [Select]

tc@box:~$ sed -n 169p limits.h
#include_next <limits.h>                /* recurse down to the real one */
Ignoring for a moment the hint included in the comment, the fact that <limits.h> is used instead of "limits.h" indicates that a system header file is required (more about this difference can be found for example here).

Therefore my assumption is that the required file is actually to be found in the "linux-headers" extension. You should be able to install it via tce-load -wi linux-headers-$(uname -r) (or if using TC 4.x 'linux-headers-KERNEL' will do as extension name).

Thank you very much for your help.

I am used to loading packages on ubuntu and compiling only when I have to.  I do not know "c" and did look at that line but it had no meaning to me.  I can only debug when libraries are missing and I can find them.

Unfortunately loading "linux-headers-3.0.3-tinycore.tcz" made no difference.

Same error.

Any other ideas on where or how to look?

linux-3.0.1_api_headers contains limits.h and it should be loaded by compiletc, is it?

[worthlutz]

Thanks I'm learning alot!

Next problem is I need librsync.h which I supposed would be in rsync-dev.tcz, librsync.tcz or something like that.
I do not see it.

I'll look around and see if I can find out how to get it elsewhere but not having much experience in compiling I'm doubtful I'll figure out where to put it.  Any help would be appreciated.

When I figure this out, I'd like to learn how to make a tc extension for rdir-backup.

Thanks for your help,

There is no librsync extension currently.

[worthlutz]

Yes, I see that.  I'm googling now for instruction on how to compile rdiff-backup so I can get librsync in the right place.  I am new at this as I do not know "c" yet or much about building stuff from source.  I just stumble along and sometimes get where I want to be.

Any help would be appreciated.

Hi worthlutz
This might have some useful stuff for you:
http://download.savannah.gnu.org/releases/rdiff-backup/
Also this wiki might be worth reading
http://wiki.rdiff-backup.org/wiki/index.php/Installations

[worthlutz]

I found librsync on github and think that I know what to do.

I just need to figure out how to compile librsync and rdiff-backup and I think that I understand that now.

Problem is that I left my power cable to my laptop at work and my test tc virtual machine is on that laptop. 

I'll let you all know how it goes as soon as I get a chance to try again.

I think that I figured out how to compile and install.

Now to get it to show up on reboot...

Am I correct in my analysis of what I've read that I can put the directory where the new stuff is installed into .filetool.lst and backup and it will show up upon reboot from then on?
Of course this is assuming I can figure out where it all went?

I suppose that the proper way to do this is create an extensions for librsync and rdiff-backup.  Creating an extension seems a bit daunting and I'm not sure exactly what is required.  I'll read some more in the wiki and the forum.

Hi worthlutz

Yes. Just don't use a leading backslash. For Ex. usr/local/blah/blah  not  /usr/local/blah/blah

Of course this is assuming I can figure out where it all went?

This may give some clue of where things are:

Code: [Select]

sudo find / -iname *rdiff*
