please any help or any link to g++ compiler are welcome.

thanks in advance

Which distro are you using? Almost all distros have prebuilt packages for gcc and its C++ cousin, g++. You shouldn't have to compile this from source.

hi again

i'm using mandrake 10.1.

and you said

could you please tell me why? i'm just curious

many thanks

Because the gcc packages are precompiled for you in rpm form by mandrake/mandriva. If the gcc packages are not on the install cds, you can set up a urpmi mirror where they can be obtained. It's much easier to install and uninstall software that way.

In mandrake run the following to see what you have currently installed in the gcc family:

$ rpm -qa | grep gcc

and post the output. From there I can tell you exactly what you need to install to get g++.

hello

ok here is the output of the commands above:

Quote:

gcc-cpp-4.0.1-5mdk
libgcc1-3.4.1-3mdk

so what shall i do now?

thanks

Open a console and run:

Code:

$ su
<enter root password>
# urpmi gcc
# urpmi gcc-c++

That should do it. You are missing both of the above packages. gcc is your basic compiler; you can't really compile anything from source without it. The gcc-c++ package installs g++, the C++ version of the gcc compiler. The "urpmi" command is the command line installation utility for mandrake/mandriva. It will install gcc and g++ for you along with any other packages needed by those packages(i.e. package dependencies). I'm pretty sure urpmi will also install libstdc++ along with g++ for example.

hi

thank you so much for help.

do you have any link to any documentation(howto...)about how to install the *.tar.gz files the best way(i mean where & system dependencies & path to install &.....).

thanks

Sure. Here's a couple links to help you get started:

http://mandrivausers.org/index.php?showtopic=10600

http://mandrivausers.org/index.php?showtopic=10615

The first deals with how to setup and use urpmi in mandrake/mandriva. The second deals with how to install rpms and installing from source with tar.gz files. For a mandrake user, I would recommend that you carefully go over the urpmi article as it is a very nice tool and once you setup the urpmi repos, you will rarely have to install from source.

hi again

thank you Sir for links and help

but one thing that did not really convinced me is why could not we install it from source from the http://gcc.gnu.org/ website;if so why do all those sources exist there if they are not useful?

any idea or suggestion are welcome and thank you again so much
