Help needed to install library

[fle86]

Hello all,

I'm new to linux and my programming skills are weak. Ubuntu 9.10 is the running system.

I need to install a library (LibRaw-0.8.5) from source code as the version I need is not present in the repositories.
So far, I managed to extract the .tar.gz, but now I have no clue how to install it and make it work with DigiKam...
I tried the sudo make install stuff, but it seems I don't do it right or what

Please help me.

Hello and welcome. For anyone to assist, we need to know far more specifically what you have tried.

First thing, do you have the basic build tools?

sudo apt-get install build-essential

For future reference, when asking a question, always include 1) the specific command used; 2) the exact output of the command.

So you might say, "I downloaded LibRaw-0.8.5.tar.gz from this site. Extracted it from nautilus. Opened a terminal to the extracted folder and tried"

reed@reed-laptop ~/Downloads/LibRaw-0.8.5 % make

If that is where the error was, then post the output. Otherwise note it built fine and then the next step:

"I did"

sudo make install

"And there error message was"

Danger Mouse error #5

Obviously that would be an unlikely message, but whatever the error was.

(By the way, I highly recommend using checkinstall in place of make install, especially if you're messing with libraries.)

Ok thanks.

I wrote it like that, because I randomly write it in the terminal

It seems that I have the build tools
brontozaver@BrontozaverSuperPower:~$ sudo apt-get install build-essential
[sudo] password for brontozaver:

build-essential is already the newest version.
build-essential set to manually installed.
The following packages were automatically installed and are no longer required:
linux-headers-2.6.31-14 kdelibs5-dbg libopenctl0 libqt4-dbg libgtlcore0
linux-headers-2.6.31-14-generic


Then. I extracted the file:
brontozaver@BrontozaverSuperPower:~$ cd ~/Downloads
brontozaver@BrontozaverSuperPower:~/Downloads$ tar xvfz LibRaw-0.8.5.tar.gz


then:
brontozaver@BrontozaverSuperPower:~/Downloads$ cd ~/LibRaw-0.8.5
bash: cd: /home/brontozaver/LibRaw-0.8.5: No such file or directory
brontozaver@BrontozaverSuperPower:~/Downloads$ cd ~/Downloads/LibRaw-0.8.5

brontozaver@BrontozaverSuperPower:~/Downloads/LibRaw-0.8.5$ sudo make install

That's it... when I open DigiKam, nothing changed, there is still the old version of the libray...

Any clue?

[reed9]

The normal process would be to do

make
sudo make install

However, it's not clear to me digikam would make use of the library regardless.

As far as I can tell, and admittedly this isn't an area I know that much about, Digikam uses libkdcraw to intreface with libraw.

LibKDcraw is a C++ interface around LibRaw library used to decode RAW picture files. This library is used by kipi-plugins, digiKam and others kipi host programs.

LibKDcraw source code is hosted by KDE4 in kdegraphics module.

I would guess you would have to build libkdcraw against libraw 0.8.5 once it's installed, and it's possible you would have to rebuild digikam itself.

[fle86]

So you say there is no chance that I do it?

Or do I have to install LibKDcraw?

[reed9]

It can probably be done. It just looks like it will be quite complicated.

I think your best bet might be to build the latest development version of digikam. Though I have no idea if they've integrated the latest libraw yet.
Download SVN KDE4 | digiKam - Photo Management Program

Otherwise, you might have to wait and see if it's included in the next Ubuntu release, or you would probably get it quicker running a bleeding edge rolling release distro like Sidux or Arch.

What exactly is the problem you're having? The current digikam doesn't support the RAW format your camera saves in?

Right. My camera RAW is supported just from the last LibRaw release.

I tried to type:

And got no result... even so I have absolutely no idea what I did

You think that with installing Sidux I would get rid of the problem? Arch seems to be even more complicated than Ubuntu...

[Rubberman]

It only makes static libraries. You probably need to get the source for DigiKam and configure/build it to use libraw.

[fle86]

And I have no idea how to do that

[Rubberman]

Ok. I looked on the DigiKam web site. It seems that the raw image stuff is found in the LibKDcraw plugin/shared-library. It likely included the libraw_r.a when it was linked, so you don't likely need libraw on your system to download/use it. However, if you have to build it, then having libraw_r is likely necessary. Do you have LibKDcraw and had DigiKam load it?
