comiling with ubuntu?

[m6arate]

I'm using the latest ubuntu release, and I was wondering if compiling would be possible if I downloaded the proper things. I currently use windows to compile, with cygwin.

[Llorean]

All you *really* need to compile is to set up a toolchain. If you're already on linux, this can be done by simply running rockboxdev.sh from the /tools/ folder of the sources, and once it has finished, changing your path to point to the newly set up compilers.

[Febs]

Yes, just run the tools/rockboxdev.sh script to set up the development environment, and you should be good to go.

[m6arate]

you say change my path to point to the new compilers, I remember having to do this for cygwin, but I have no Idea how to do it with ubuntu. Will I have to do this manually, and if so, how?

[Rincewind]

you have to add this line to the file ".bashrc" in your home directory:

export PATH=$PATH:/usr/local/m68k-elf/bin

but it is possible that the rockboxdev.sh script says that you have to add more to your path, then you have to add what it says there.

Make your PATH include :/usr/local/arm-elf/bin

you need to install a couple of development tools for your system, especially make and gcc. Search your package manager for them.

[m6arate]

did that, still spit out errors

[bluebrother]

why don't you just read the output yourself?

configure: error: installation or configuration problem: C compiler cannot create executables.

Should be pretty much self explanating -- something is missing from your gcc installation. Maybe there's a "development" meta package that installs everything needed for compiling?

[Spug]

Yes, it's called "build-essential".

Also:

Make your PATH include :/usr/local/arm-elf/bin

[m6arate]

okay Ill try installing that. And I know to add that to the path, but decided to wait until I had a working installation.

[m6arate]

alright. it installed fine, and I started compiling, but I immediately got errors about arm-elf-gcc

make[1]: arm-elf-gcc: Command not found
make[1]: *** [/home/mike/stuff/rockbox/1/rockbox/h20/firmware/sysfont.o] Error 127
make: *** [all] Error 2
mike@mike-desktop:~/stuff/rockbox/1/rockbox/h20$

I searched the package manager, didnt find anything that seemed like it. I remember having trouble getting this installed on windows (cgywin) and eventually having to just download a file somewhere and add it to the bin. Is that what I should do again here?

[Febs]

At the risk of stating the obvious, did you change your path to include arm-elf/bin?

[bluebrother]

as the first line of your output clearly tells it can't find the command, which in turn means that you either installed the compiler to a different path than the one you added to the PATH variable or you didn't add the path to the variable.

[m6arate]

ah silly me. I forgot. Its working now. thank you all for helping/putting up with me
