Setting up a cygwin Rockbox development environment
has created precompiled Cygwin packages for the SH-1, 68K/Coldfire and ARM cross GCC tools.
New and inexperienced users may find the brief outline on this page insufficient to get up and running. If so, try the CygwinInstallWithScreenShots
Step 1: Download the cygwin installer
Go to the cygwin home page, www.cygwin.com
and download setup.exe from there ("Install or update now!").
Step 2: Install the base development environment
Run the setup.exe you just downloaded. If you are unsure about the questions asked by the installer, just choose the default, until you get to package selection. That bit is important.
Step 2.1: Package selection.
When you are asked to select the packages to install, select the following :
(Make sure you leave the selection for "Base" untouched)
- Archive - zip
- Archive - unzip
- Devel - binutils
- Devel - gcc
- Devel - gcc-g++
- Devel - gcc-mingw-core
- Devel - gdb (if you want to debug simulator code)
- Devel - libiconv
- Devel - make
- Devel - mingw-runtime
- Devel - patchutils
- Devel - subversion
- Editors - nano (to change the cross compiler path)
- Interpreters - perl
- Net - Curl
- Text - tetex-base (if you want to build the manual)
- Text - tetex-extra (if you want to build the manual)
- X11 - libfreetype-devel (if you want to convert ttf to anti-aliased fonts)
- X11 - libfreetype6 (if you want to convert ttf to anti-aliased fonts)
Step 3: Select the Rockbox mirror site and install
Start the Setup program again. When the installer prompts you for a mirror site URL, enter http://download.rockbox.org/cygwin/
in the "User URL" field and click "Add".
In case you encounter an error regarding missing .sig file, supply the -X (--no-verify) command-line flag when using Cygwin's setup.exe. This can be added into the command-line invocation in a Windows shortcut, for convenience.
Select the packages you need. We suggest you select all of them, since you will be needing them when test compiling your code for all Rockbox targets. They should be listed as follows:
- Devel - sdl (for the uisimulator)
- Devel - sh-elf-binutils
- Devel - sh-elf-gcc
Most new developers will want to compile for ARM. Unfortunately, we do NOT provide prebuilt ARM or Coldfire compiler binaries suitable for building rockbox, and attempting to use the ones in the installer will most likely fail.
If you want to build for an ARM or Coldfire target, you can skip the rest of this guide and follow the instructions here to build the latest compiler: CrossCompiler
Step 4: Add the cross-compiler directory to your path
To successfully compile Rockbox, the cross compiler directory has to be in your path. This is automatically done by the installation script
, but if that fails for some reason, there are a couple ways of doing so, here's one:
Edit using nano or vi (not Notepad or Wordpad in Windows) /etc/profile and add ":/opt/sh/bin:/opt/m68k/bin:/opt/arm/bin" (without the quotation marks) to the end of the line that says:
so that it reads:
Save the changes, exit cygwin and restart cygwin.
An alternative way is to temporarily tell the compiler to accept commands from your build directory (where you wish to build rockbox). This can be done by typing the following into cygwin, after navigating to your build directory
Note that you have to type this in everytime you wish to compile rockbox.
Done. Happy hacking!
Step 5: Add inputenx to your teTeX installation
To be able to build the manual you will need to manually install inputenx (required since r27481). Please download inputenx.dtx
and follow the instructions below:
1) Unpacking. The .dtx file is a self-extracting docstrip archive. The files are extracted by running the .dtx through plain TEX:
2) Copy all extracted file to the path
3) If your TEX distribution (teTEX, mikTEX, . . . ) relies on file name databases, you must refresh these. For example, teTEX users run
Step 6: Update SDL on your cygwin installation
You might need to update SDL, if the rockbox simulation does not compile (e.g. missing SDL_stdinc.h).
1) Download the current SDL package SDL-1.2.14
2) Uncompress the package to a local path, enter this path, compile and install it:
./configure && make && make install
