View source for Compile on the Pandora

torpor described how to [http://www.gp32x.com/board/index.php?/topic/53964-cross-compiling-is-bollocks-toolchains-are-bollocks-use-your-pandora-to-build-apps/ build apps directly on the Pandora].

Please note that as of March 2011, you will break your install if you follow those instructions directly!  The angstrom "unstable" distribution is well named.

You can try the following:

1. I found that the www.angstrom-distribution.org repo was very slow, so changed the config files in /etc/opkg/ to use us.feeds.angstrom-distribution.org instead.

2. Enable sshd, and ssh in from another machine.  This helps keep control when things break.  To get root:

  sudo bash

3. Set up a [http://pandorawiki.org/Extend_Utils#Creating_a_Root_or_Home_Overlay_PreMount root overlay] on your SD card.  This gives you a way to try again when things break, and has other benefits.  I added /home/ to the overlay also.

4. Mount the overlay.  Check this worked, with "mount" or "df".

5. Get new fresh package lists:

  opkg update

6. ncurses packaging seems to be broken, and ncurses is important!  So, do this first (in the overlay), or be prepared for everything to break later:

  opkg install libncurses5

7. Install dev packages:

  opkg install gcc gcc-symlinks make binutils cpp cpp-symlinks g++ g++-symlinks libstdc++-dev

8. Try to compile "hello world".  Mine didn't find libgcc_s, this fixed it:

  opkg install libgcc1   # not sure if this was needed
  ln -s /lib/libgcc_s.so.1 /usr/lib/gcc/arm-angstrom-linux-gnueabi/4.3.3/libgcc_s.so

9. Install extra dev libs:

  opkg install libgles-omap3-dev
  opkg install libsdl-1.2-dev libsdl-gfx-dev libsdl-image-1.2-dev libsdl-mixer-dev libsdl-net-1.2-dev libsdl-ttf-2.0-dev

10. I had trouble with libsdl-image-1.2-dev and libpng, so did something like this (there might be some errors):

  opkg info libsdl-image-1.2-dev      # to see the deps
  opkg install libz-dev libpng-dev libjpeg-dev libtiff-dev libpng12-dev libc6-dev libsdl-1.2-dev
  opkg install --nodeps libsdl-image-1.2-dev
  ln -s libpng.so.3 /usr/lib/libpng.so

11. Install optional extra stuff, if you want them:

  opkg install vim vim-syntax
  opkg install libgles-omap3-demos
  opkg install screen git rsync


The above was from memory, I didn't re-test it because it took too long even the first time!  If you find other problems or quirks, please correct it.
