Hey,

I am trying to install gcc so I can compile C++ on a Virtual linux machine I have on my pc. I went to the GNU website and downloaded gcc-g++-4.5.0.tar.gz, unzipped and un-tarred it. This left me with a folder named gcc-4.5.0 which itself contained two folders. One named gcc and another named libstdc++-v3. From trying to follow a (not very clear) guide online I created another folder in the libstdc++-v3 folder named objdir into which I copied the configre executable. I then tried to run it here and was told that I was missing an install.sh file. I found one of these from somewhere else on my machine and copied it into the libstdc++-v3 folder. Now when I try to run the configure executable from the objdir folder I get a message saying "configure: error: cannot run /bin/bash ./config.sub.

Basically all I want to do is get gcc up and running so I can compile some code. What I have been doing so far is probably way off the mark but its as far as I could get from following stuff online.

Any help most appreciated.

Cheers

What distribution are you using? (Hint: KDE is not a distro, but a desktop environment - look for something like Ubuntu, Debian, Red Hat, Mint, Slackware, etc) Typically you can install gcc easily from your distribution's repositories, which is much easier than installing it from the GNU website.

Am using kubuntu. Pretty sure its just ubuntu with KDE.

Sounds great. Where do I go to find the repositories?

Quite simple : Use the package manager = Synaptic.
( And hit the 'Refresh' button if not 20,000-30,000 packages are shown.)
Synaptic has a "Search": Look for gcc, g++. You will need both. g++=gcc-c++.

Or use the command line :
1) sudo apt-get update ( to refresh the package lists.)
2) sudo apt-get install gcc g++

WOW!! That worked an absolute treat!

Just had to type 2 lines. So simple.

Thanks!!!!

In fact, the real line should have been
With only GCC, you will miss some important dev tools required for compiling such as binutils (assembly tools) and the make file tools. The way you tried to install GCC can't work, as it is the source archive, you need a compiler to compile it first

You can also mark your thread as "[SOLVED]". The "apt-get install" command can be used to install anything. "sudo apt-get install install mysql firefox" will install mysql and firefox.

It actually should be build-essential, not built.

I don't know why the "install 'build-essential' advise"
is seen so often. It's mainly dpkg-dev + its dependencies.
http://packages.ubuntu.com/lucid/build-essential
QUOTE :
"If you do not plan to build Debian packages, you don't need this package."

dpkg-dev + dependencies :
http://packages.ubuntu.com/lucid/dpkg-dev

P.S. : GCC : It's wrong to copy the 'configure' script into the 'objdir'.
The by gcc recommended build method :
http://www.linuxfromscratch.org/lfs/view/development/
( gcc pass 1 , gcc pass 2 , gcc install (pass 3)).

PPS : @Elv13 : 'binutils' is a dependency for gcc and is installed.
(autoconf automake make libtool bison flex : required too for the most builds.)

Thanks Elv13!

I will try build-essential when I am back at home and not at work. The advice given by knudfl has got me up and running and able to compile using gcc.

Thanks for the amasing help!!

That's the Linux way of installing things!
