Hi (linux newbie here)

I'm attempting to get gPhoto (and the associated library) installed. In the process, I believe I mistakenly installed an older gPhoto version with a newer library. Needless to say, it's not working as it once was. I cannot seem to reinstall.

Is there a way to unistall all gphoto and libgphoto stuff somewhat cleanly?

Thanks

Uninstall *.tgz is done either with
pkgtool --> uninstall or removepkg packagename.

If you compiled from source try make clean or make uninstall and you should have your system clean again.

Maybe it helps if you can post any error messages when trying to reinstall?

If you compiled from source use use 'make uninstall' as root

If you have done 'make clean' or 'make distclean' you will need to './configure' again, and then 'make uninstall'

Correct me if I'm wrong but 'make clean' deletes the list of files needed to be made and copied, which 'make uninstall' needs to work.

Another way is to compile it again and then use checkinstall to create a package out of it and to install the program (again). After that you can use the Slackware pkgtools to uninstall it.

0) install checkinstall if haven't done this: http://slackware.it/en/pb/package.ph...l-1.5.3-i486-2

1) do "./configure" and "make" as usual

2) instead of "make install" type "checkinstall" -- this should build and install the package. If it does not install the created package automatically, do it yourself with "installpkg <name of the package>"

3) type "removepkg <name of the package>" and then install your newer version again.


The chances are good, btw, that with reinstalling the working package the libraries you mentioned will get overwritten with the working stuff. Maybe try that first.

Perfect, and yes I did have to install from source. I used the "make uninstall" command for both gphoto2 and the library. I followed that up with an updatedb and "slocate *gphoto2*" and slocate "slocate *libphoto*". The uninstallation script worked perfect...no traces of these two programs.

I think freshly installed the proper library and program again and everything works perfect

Is there a good HOWTO or something about program installation in general? I'd like to understand a bit more about where program components go. I don't like just assuming installers put everything where it's supposed to go.

Thanks all

The most applications allow to give something like "make install DESTDIR=/path/some/where". Some differ slightly and don't support this or use another syntax like "make PREFIX=/path/some/where". If you use this, you can check which files will be installed with a regular "make install". The appropriate one should be stated in the README or INSTALL file that comes with the source code.

Checkinstall is another way -- just do the "checkinstall" instead of "make install" and check the contents by unpacking it somewhere with "explodepkg".

A third way would of course be to check the Makefile, but I think that is tricky if you are not used to do this (nor am I).

I'll deffinatly install checkinstall. Looks useful. And I too shall pass on reviewing the makefiles.

However, I'm still a bit curious as to where programs (generally) go when you define the installation location. For example, lets say I'm installing KWhatever (a KDE application) from source. In configure, I pass the --prefix /usr/local. I then make and install.

I assume the program has a lot of stuff. For example:
1) Help files (man, documentation, etc)
2) Library files
3) Executables
4) Links to the application in the "start menu".
5) Other stuff ???

In Microsoft world, you can pretty much count on applications installing the same way. Example:
1) Help files go to c:\program files\app
2) Library files go to c:\windows or the app directory
3) Exe's c:\program files\app
4) Links c:\documents and settings\all users\start menu

Is there general locations (a standard if you will) of where program components go when installed from source?

Thanks

Two overviews:
http://rute.2038bug.com/node20.html....00000000000000
http://www.tuxfiles.org/linuxhelp/linuxdir.html

Or google for Linux Directory Structure.

Excellent links. I feel much better now that I understand how the program gets broken down.

Also, the checkinstall utility looks really good. Deffinatly a step worth taking.

Thanks greatly

http://www.slackersbible.org/book/ and the Slackware Linux Essentials II(Slackware Linux) by Alan Hicks and others(available in documents section at linuxpackages site as on-line version) both have good package management sections too. Good luck.
