hey guys,

just starting out using Linux, im having trouble figuring out how the GCC C compiler works on linux, i know about the programming side as i have been using one on Windows XP, now iv moved onto Linux, i have managed to install the GCC file using YaST but cant seem to find it, is it an application???? how do i compile, write and execute the file i have written using GCC???


any information would be most appreciated


thank you very much

"how do i compile, write and execute the file i have written using GCC???"
Here is a gcc tutorial.

"i have managed to install the GCC file using YaST but cant seem to find it,"

Look for gcc (lower case) with this command:
which gcc

in a console, you can do
$gcc -o program program.c
that basically creates a program called "program" from a source file called "program.c".

Hello,

I'm also new to Linux. I'm running a Slackware 10.0 derivative called Topologilinux that lets me experiment/run Linux without much hassle.

It came with gcc 3.3.4 already installed plus several glib's. I'm trying to install software for my Alcatel USB ADSL modem so I can use the net but it needs to compile and produce some executables.
While attempting the compilation it stops with a final message saying "C compiler cannot create executables". I've search through various forums on the issue and it looks like it has to deal with one of several different causes.
I tried upgrading to gcc 3.4.3 but the problem is still alive. The following is an extract of config.log:

Could anybody tell me what could be the most probable cause for this?
Needless to say, ANY help is appreciated

ag, you need to install the rest of the packages in the d/ directory (specifically, your missing binutils ).

Thank you, __J. It seems like certainly binutils is not installed. I'll install it right away and post my findings.

Before that, I guess it may not matter but, should I switch back to gcc 3.3.4?

Thanks again!


(Few days later)

I solved the problem.
Here are the packages I ended up needing:

binutils-2.15.90.0.3-i486-1.tgz
gcc-3.3.4-i486-1.tgz
gcc-g++-3.3.4-i486-1.tgz
kernel-headers-2.4.26-i386-3.tgz
make-3.80-i386-1.tgz

Thanks!
