compile C programs, Kdevelop & terminal

[gian748]

Dear all,

I’m a C user. I “was born” with borland c interface (1998-96). It was simple. :)

Now I have started with LINUX and I have found enormous problems to use my C old programs and make new ones.

First. I have installed K develop but today, to compile and run a common C-language program I have to make a project. So I do it, and I start to build it. But all the times a windows opens:” …there is no make file in this directory and no configure script fror this project. Run automake a& friends and configure first?”

If I press “run them” the systems says “ there is neither a Makefile.cvs nor an autogen.sh.script in the project directory.

If I press “Do not run” it obviously do nothing.

Thus I’m not able to run hello.c program, neither!

What I have to do? :confused:

I have tried to compile online from terminal. Thus I have searched for a list with a brief explanation of the principals options to compile, link, make and run c programs. I have found the manual at the link : http://www.gnu.org/software/gcc/onlinedocs/


But…..it’s just a list without any explanation. ](*,)

Has someone a list WITH short explanation of the most commons options to compile, link, make and run c programs from terminal?

Many thanks

Only if you are using an IDE (e.g. Kdevelop). Why not simplify your life and use the command-line to compile/link your programs? I hope you haven't avoided this option because of fear of changing to something more hands-on. It is actually quite simple, and eliminates a lot of the grief of developing simple applications.

Btw, if you have not already done so, ensure to install the development tools on your system.

sudo apt-get install build-essential
(note, it might be "essentials", not "essential".)

This may be what is causing Kdevelop its problems.

To compile a C program from the terminal:

gcc -Wall -pedantic -std=gnu99 Hello.c -o Hello

-Wall forces all warnings to be displayed
-pedantic displays warnings when code is not ISO C compliant
-std=gnu99 instructs the compiler to use the 1999 C standards (although GNU has not fully implemented them.) The compiler, by default, uses the ancient 1989 standards.
-o is used to instruct the GCC linker what to name the resulting executable

When done, run the program:

./Hello


P.S. Typing "gcc -Wall -pedantic -std=gnu99" everytime you want to compile a program can become tedious. I suggest you add an alias to your ~/.bashrc file (using kedit or other editing application):

alias gcc='gcc -Wall -pedantic -std=gnu99'
then source the file when it has been saved.

source ~/.bashrc

...I have installed the develop tools with "sudo apt-get install build-essential" but Kdevelop still do exactly the same errors....

:confused:

then I tried the terminal possibility and this is , unfortunately, the result:

...ok, I'm happy to say that I'm stupid!!!!

A friend of mine has remembered me that Linux is case sensitive, I have forgotten that point.

So I was succesfull in compiling c-code by terminal with your dwhitney67 suggestions!!!!

thanks again!!!
