Compiling under linux???

[adrien1977]

Hi
I just recently starting using rockbox (which I find it great) and I'd like to dive into the code a little bit. I have old C experience (almost none) I am mostly a JAVA dev.

Anyway, I've been reading and doing some research on this forum, but I could not find anything regarding help to compile under linux.

I have the latest kubuntu release.

Does anyone has some guides or suggestions?
I'd really like to avoid using cygwin

Thanks a bunch for the help

Take the Cygwin install guide, and skip any steps that say "Run cygwin" or "Install cygwin"


I mean, you use the same CVS command line, and the all the same commands, you just do them in Linux instead of in Cygwin... See the CrossCompiler wiki page, or use the shell script in the /tools/ folder of the source for setting up the necessary cross compilers since you aren't getting them bundled with Cygwin.

The first thing to do is to build a cross compiler.  The developers' documentation is mainly in the Wiki, rather than on the forums.

Hope that helps!

ok then
Let me try this right now
I'll let you know.
THnaks for the fast response

[bluebrother]

you could also use the script rockboxdev.sh in the tools directory which sets up the cross compiler environment for your.

[adrien1977]

ok
rockboxdev.sh is running right now.
After that I'll try to compile the code and see what happens

I'll keep you posted

[adrien1977]

is that normal?

I tried to compile and got this

I did compile the crosscompiler though

Did you update your path to include a path to the cross-compiler?

[adrien1977]

oups.....
My bad
I thought that the script did it automatically

I modified the PATH, execute the configure  and everything went fine
I execute make and it seemed to work fine
I did make zip and created the zip.

Thanks a lot for the help

Now I have another quesiton.

What is that SDL they talk about in the how to build the simulator?

thanks

[dan_a]

SDL is a graphics library.
There are probably packages available for Kubuntu called something like "libsdl" and "libsdl-devel" (I'm not sure, I don't use Kubuntu.)  Install both of these and you should be able to build the simulator.

[adrien1977]

You were right
I installed them and it compiled fine
It also executed fine
thanks for the help
