Comment installer un logiciel sous Linux

si l'install lui propose de le compiler, je vois pas ce que "sudo aptitude install ..."viens faire la ...

j'ai décompressé le dossier sur le bureau mais après euh ... je ne vois vraiment pas !
alors pour faire plus simple, tu va copier le fichier decompressé dans ton dossier personnel et refaire les commandes

par defaut , le terminal s'ouvre sur ton dossier perso, ca simplifie les choses mais c'est vraiment trés simple une fois que tu as compris ...

As-tu essayé de l'installer avec le gestionnaire de paquets ?

Salut,

Lis le fichier "INSTALL", tout y est mentionné concernant l'installation ;-))

Extrait du INSTALL :

Quick Installation
==================

        GraphCalc will not actually install into your system binary
directory.  Here are the build directions.  Make sure you have the
libraries listed below first though.

        qmake
        make
        ./graphcalc

Detailed Installation
=====================

        This pre-stable version of GraphCalc for Linux does not include any
specific installation.  I do not recommend you use this version for
anything except testing and development.  These instructions will help
you produce the binary, but actually copying it to a directory like
/usr/local/bin is up to you.

        GraphCalc for Linux depends on a number of libraries.  Before you
begin, make sure you have the following packages already installed:

        - KDE/QT libraries (http://www.kde.org)
        - Ginac libraries (http://www.ginac.de)

        KDE/QT is already provided on most linux systems.  Chances are that
you already have the required libraries for this.

        Ginac is a GPL'd math parsing system that takes care of the
underlying computations.  These libraries must be present before
GraphCalc will compile.  Ginac also depends on a couple of libraries
before it will compile, like CLN and GMP libraries.  Refer to the Ginac
website, http://www.ginac.de, for detailed installation instructions.
Or, if you are running my favorite distribution (Gentoo), just do a
"emerge ginac".

        After those libraries are installed, perform the following steps:

        cd /whateverpath/linux

                This will take you into GraphCalc's source directory

        qmake

                This will perform QT's make function and generate a good Makefile
                for us.

        make

                Now that we have a good Makefile, this will produce our binary.
                This step typically takes between 1 and 2 minutes.  After you
                make the binary, all you have to do is run it.

        ./graphcalc

        Good luck.  Drop a note to gcalc-devel@lists.sourceforge.net if you
        have any issues you'd like to discuss.

Les bibliothèques tu dois les trouver via ton gestionnaires de paquets. Ensuite il te suffit de te rendre dans le répertoire où tu as extrait ton programme et d'enchainer les 3 commandes :
qmake
make
./graphcalc
