General Linux programming questions

d3c3it

Hi
i want to start programming in C and maybe some java again. I gave up before because i found it a real hassle under windows but now im in linux and it seems to make sense now. Ive made a couple of bash scripts but what i wanted to know is how do i go about compiling any of the source i make. im going to be using vi no doubt for programming but do i have to emerge anything? like with java would i have to emerge the sun jdk? and how would i go about compiling C/C++ files under linux? Ive got a learn java in 24days book so i assume you just use the same commands as is describe in the book? *the book is designed with use of the sun jdk or sdk, i get confused of which:)*
Thanks in advance to any replies

Just follow the Gentoo Java Guide to get java setup properly. As for C... If you got gentoo installed you have everything you need for it.
Just 'gcc -o mycompiledprogram mysourcefile.c' and your in business.

No, makefiles are a whole different ball of wax. If you want to start developing large scale C apps that other ppl will use, then you will need to learn about makefiles and all that, but for just teaching yourself C, the gcc is all you need.

For java coding you just need a working JDK. If you want to use the actual Sun products, as I do, you need to emerge one of the following:

You do what Fillzee said, 'gcc -o foo foo.c' where foo is the compiled binary output and foo.c is your C source file.

The make command will look in the current directory for a file called 'Makefile'. This file contains rules on how to compile a program. Any commands you pass to make are interpreted as make targets (ie. what you want make to do, either to compile or install or whatever rules you defined in your Makefile). You should not worry about this yet, but as michaelb said, you will probably need to work with Makefiles if you start getting multiple source files or libraries.
