Random Notes

• 100% working on my end for Bare Bone and Meaty Skeleton
• WSL is running Ubuntu 14.04
• WSL does not have an install of GRUB (use grub-pc-bin)
• WSL has a rather out of date version of GCC install by default (4.8.2)
• To build GCC need bison, flex, byacc, as well as the prereqs mentioned on GCC_Cross-Compiler#Downloading_the_Source_Code
• Need to update pre-built gcc, Server Fault - How do I use the latest GCC on Ubuntu? use gcc-6 instead of gcc-4.9
• Recommended list of packages to apt-get before starting
  • git
  • bison
  • flex
  • byacc
  • build-essential
  • gcc-6 (After adding PPA: sudo add-apt-repository ppa:ubuntu-toolchain-r/test)
  • libgmp3-dev
  • libmpfr-dev
  • libmpc-dev
  • texinfo
  • grub-pc-bin
  • xorriso
• Need to come up with steps and test all of the above to make sure it is enough.
• Optional/Helpful packages to apt-get
  • genisoimage (provides "isoinfo" which can be helpful for sanity checking iso files)
  • nasm (if you prefer Intel syntax over AT&T)
• Bare_Bones does work with all prereqs mentioned above. Running the kernel (with -kernel) or the iso (with -cdrom) in QEMU works (confirmed by myself +2 on the forums)
• Meaty_Skeleton works same as the Bare Bones (works for me in qemu, maybe others, though unconfirmed by myself)
• For cleanup purposes, [1]This is a good way to see all "installed" packages. Adding a "> file.txt" after it will allow you to easily reference and review the list to decide what needs to be removed. And "sudo apt-get autoremove" should be your final command (repeated until nothing shows up if necessary)
