Title: problem installing rdiff-backup
Post by: worthlutz on November 11, 2011, 06:11:54 AM

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 (http://gcc.gnu.org/onlinedocs/cpp/Include-Syntax.html)).

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?

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,
Worth

There is no librsync extension currently.

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/ (http://download.savannah.gnu.org/releases/rdiff-backup/)
Also this wiki might be worth reading
http://wiki.rdiff-backup.org/wiki/index.php/Installations (http://wiki.rdiff-backup.org/wiki/index.php/Installations)

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.

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

This may give some clue of where things are:

Code: [Select]

sudo find / -iname *rdiff*
