LibreOffice installation memory requirements

[utu]

A note about LibreOffice installation memory requirements.

Having had some trouble in failing to install LibreOffice on my
puny 2 Gb LiveUSB, I offer the following notes.

My going in assumption was that if you had an image of a working
LibreOffice setup, it would occupy something like 400 Mb.
A compressed image of this might take around 150 Mb. I'd be happy
to be pointed to verifiably correct data in this regard if I'm
way of on this.

With that assumption, I was not pleased to find than a generous
allotment of 1200 Mb for my PCLinuxOS LiveUSB was not graciously
received by PCLinuxOS's lomanager 3.4.1. In my situation,
lomanager gives a credible & interesting five minutes of
apparently successful activity, which turns out in fact to be
a mere 'silent failure'. No product & no messages.

I think my assumptions are necessary, but not sufficient, by a
small but crucial margin.  LO's requirements are stated in the
following link.

http://www.libreoffice.org/get-help/system-requirements/

Installation, not the final product, requires about 1550 Mb for
a successful operation I think is the proper interpretation here.
That's 350 Mb more than I planned to donate to this cause.

It looks like I'll not have a 2 Gb version of PCLinuxOS complete
with LibreOffice under current conditions, unless perhaps I bite
the bullet and learn how to re-master for myself.

A note about LibreOffice installation memory requirements.

I'm a tad confused    - are you referring to memory or storage requirements?

And are you creating a LiveUSB and then installing LibreOffice to it?

[scoundrel]

though a bit garbled, he is talking about installing pclos and LO onto usb stick

[Just17]

Anything installed to a Persistent LiveUSB will not be compressed like the original ISO.

If you wish LO to be included in compressed form then your best bet is to remaster an install with it already installed.
Then use the resultant ISO on the USB stick.

An update to lomanager is on its way to the repos. pinoc added some features.

Remastering an installed system is easy. ---
Perform a full update
Install the apps you want.
Run bleachbit and bleachbit-root to clean up your system.
As root, run the command umount -a to unmount non-system partitions.
Run the command mylivecd >>nameofyourchoice<<.iso.

Be sure not to short yourself on space to perform the remastering. The command df will tell you how much space you have free, as well as how much you have used.

Hi again utu,
we had this discussion already here yesterday, right? To add to this, when running a live-system the available free space is ~ 0.5 x RAM, which means you will need to have a system with 3GB RAM to install LO in the live-session and this works fine, trust me. And as explained before, and here again by Just19 and Neal, your best bet is to include it in your remaster, just follow this advice and save yourself some time and hassle.
-p.

......  maybe if a Swap partition was set on the live session the memory requirements would be overcome ....  I don't know, never tried to install LO on a live session with limited resources......

@ menotu
Quite right. My title IS confusing; my bad.
I meant to convey how much USB storage is required.
Not talking about RAM at all

@ pinoc
I note that mylivecd, by virtue of remasterme, has an initial check
of space before proceeding.  I think something similar is in order
for lomanager. List out remasterme to see what I mean.

For good measure, some more helpful error message than 'failed silently'
would be a nice touch. 'failed silently' after five minutes is almost
dark humor.

If lomanager is not meant for LiveUSB use, that should be spelled-out
somewhere. I note that Texstar makes a distinction between myliveCD
and (at least the possibility of) myliveUSB, which makes me wonder
about lomanager.

[pinoc]

Hi utu,
still don't understand what you did. Here is what I did: using PCLinuxOS Live USB Creator I installed the LXDE-iso 2011.6 to a 16GB USB-stick. Now I boot this LXDE-iso from the USB-stick and look how much free space there is: as expected the free disk space in a live-session is ~50% of the RAM available on a given PC. This free disk space amount is independent of booting normally or with persistence, as well as the size of the USB-drive.  For example if you plug this USB-drive into a PC with 4GB RAM, then your initial free disk space will be 1.8GB which is more than enough to install LO with lomanager. Now if you start playing around and opening, or installing all kind of applications the amount of free disk space will decrease. However, as long as your free disk space is larger than 1.2GB you can run lomanager to install Java+LO, if there is insufficient space then lomanager will tell you so.
Now you mentioned that lomanager started and then disappeared, which could happen if you use lomanager 3.4.0 (having a bug which is fixed now in 3.4.1-2). Boot your live-USB, update lomanager to 3.4.1-2, and then run lomanager. If you do this on a PC with $GB RAM you can install LO without problems in the live-session.
-p.

I hesitate to respond.  I'm being called a troll by longtom.
I do appreciate you've been patient with me.
I think I fully appreciate PCLinuxOS as a FINE OS.

I had hoped to offer some useful notes on lomanager, not criticisms.
lomager operates in a different manner than I wish to proceed, that's all.
Even so, lomanager deserves some refinements I hoped to spell out.
Feel free to ignore these, no harm done.

My niche is a 2 Gb LiveUSB with Linux, LXDE, good wifi & LibreOffice.
I'm obiously no power user.
My everyday system by choice is a Knoppix 6.4.4 LiveUSB with all that plus some
reserve persistence and an on-board persistence backup.

My interest here is to make a similar 2 Gb LiveUSB based on PCLinuxOS.
I'm convinced that bringing in LO into PCLinuxOS 2011.06-full, as lomanager
does, does not  work on a 2 GB setup.  2 Gb is a little too small.  Install will
predictably fail at  >1200 Mb attempted LO install.  LO needs 1550 Mb for
the installation process to proceed.  I could solve this with a larger USB,
but that's not my niche.  I'll bet a 4 Gb install would work, but I'd not be
happy even so, because I think this is an inefficient way to go.

I expect to get smarter about re-mastering and to find a way to bring LO
into the compressed image of PCLinuxOS ala Knoppix 6.4 but I'm a slow
learner, this avenue will take some time.  I'll keep this to  myself, so a not
to increase my subversive reputation.

I've not used lomanager 3.4.0, only 3.4.1 and not  3.4.1-x.
It sounds like the memory test idea is already taken care of in 3.4.1-x
I disagree by a small amount that anything larger than 1200 Mb free
will work.  I can & have demonstrated it to fail at 1200 Mb.  Also, the
LO spec says they need 1550 Mb to INSTALL. (Install is the key word, I think)
Be that as it may, I don't want to use 1200 or 1550 Mb for LO.  It will require
less than 200 Mb in the compressed image. That's how it's done in Knoppix.

In each of your posts, you say this in one way or another. Now you've informed us, you can stop. Or do you like longtom thinking you're a troll?

I've used lomanager, both live and installed. It is very easy to use. 1200 MB is doable in a live situation.

That's how it's done in Knoppix.

This is PCLinuxOS, not Knoppix.

You want us to provide an ISO with LibreOffice preinstalled? And provide server space for it? Just for you? I'd bet the Knoppix devs wouldn't do that just for you.
Easy to use tools are provided for you to create your own remaster.

I think I can understand utu.

He might be simply stating that his ventures with a PCLinuxOS mini + installing LO on a 2Gb USB key is presently unattainable but expect to get it eventually.

I don't think utu wants anything else other than suggestions, which our experts had already provided and I hope he understood.

I respect that he wants to accomplish this task but I'm afraid it will be a tall order. A year ago, maybe but with the growing size of most apps, utu could be running out of time.

One suggestion. Perhaps if utu trims a bit (either on the PCLinuxOS mini or one or two LO componenets), maybe he could squeeze in the limitations in his goal? Of course that would not be the same ... as Knoppix and PCLinuxOS are clearly not the same.

But with Linux, I believe it is possible.

@utu. Perhaps you ought to compare Knoppix's installed apps  (including the compressed LO) with the PCLinuxOS mini. That should be a good place to start.

Anyway, good luck on your task and I am hoping you can succeed. One thing though, if you do accomplish your goals, we would be interested in how you did it.

Best to you.

No problem, as has been pointed out.

Install LO and then remaster =>  you then have what you want.

It should take less time to learn how & to do that, than you have invested in posting about the subject.

I hope you consider doing things the PCLOS way, and not some other way you have been using previously .....  whether that be MS, Bunty, Knoppix or whatever.

The tools are there ......  up to you to use them 

EDIT:-
         

I note that mylivecd, by virtue of remasterme, has an initial check
of space before proceeding.  I think something similar is in order
for lomanager. List out remasterme to see what I mean.

Is remasterme (/usr/bin/remasterme) included in PCLOS these days?  I thought it was deprecated ...  note to self -- must check


regards.

You are correct, Just19. It has been deprecated. It worked with mklivecd; i.e. it was used with 2009 and earlier.

May be deprecated, but still exists, depending on your date of initial installation possibly.

From my KDE4 MiniMe 2010 installation:

[root@fatman ~]# which remasterme
/usr/bin/remasterme

I'm fully upgraded up to today, and nothing has actually removed it.
