Bugs in the Floppinux tutorial

[82MHz]

Hi there,

first of all, great project! I followed the tutorial today and noticed a few bugs in it:

• The git clone call for the kernel contains an error
  • Wrong: git clone --depth=1 --branch v6.14.y https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
  • Right: git clone --depth=1 --branch v6.14.11 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
• The init rc script expects ln and mkdir to be present, so these need to be included in busybox
• The first two setup paths for the cross compiler setup are missing a / after "${BASE}":
  • Wrong: sed -i "s|.*CONFIG_CROSS_COMPILER_PREFIX.*|CONFIG_CROSS_COMPILER_PREFIX="\"${BASE}"i486-linux-musl-cross/bin/i486-linux-musl-\"|" .config
  • Right: sed -i "s|.*CONFIG_CROSS_COMPILER_PREFIX.*|CONFIG_CROSS_COMPILER_PREFIX="\"${BASE}"/i486-linux-musl-cross/bin/i486-linux-musl-\"|" .config
  • Wrong: sed -i "s|.*CONFIG_SYSROOT.*|CONFIG_SYSROOT=\""${BASE}"i486-linux-musl-cross\"|" .config
  • Right: sed -i "s|.*CONFIG_SYSROOT.*|CONFIG_SYSROOT=\""${BASE}"/i486-linux-musl-cross\"|" .config

I also added /proc file system support in the kernel menuconfig under File systems -> Pseudo file systems. Not sure if this is really necessary though.

Also, the provided floppinux image doesn't boot in qemu and gets stuck after Loading rootfs.cpio.gz...ok. The image that I built according to the tutorial (both with and without the fixed I mentioned above) boots.

I also added /proc file system support in the kernel menuconfig under File systems -> Pseudo file systems. Not sure if this is really necessary though.

Adding /proc filesystem is necessary for tools like top to function. Also the line mount -t proc none /proc in the init script would be pointless without it.

I would also suggest reordering the linux menuconfig instructions to match the displayed order in the menu. If you're having difficulties finding entries while using menuconfig, one can use "/" to access an interactive search menu.

On the sed commands: I don't remember encountering any problems using the original version when I followed the instructions 5 days ago.

Thanks!

I'm testing those and will update the tutorial (on git and hosted on the website).

Some more fixes:

Make it executable: chmod +x syslinux.cfg

I don't thing there's a reason to make the config file executable - it works fine without it.

ln -s /proc/mounts /etc/mtab

The init rc script uses ln, but it's missing from the BusyBox configuration.

[...]
Additional CFLAGS (EXTRA_CFLAGS) [] (NEW) 
Additional LDFLAGS (EXTRA_LDFLAGS) [] (NEW)
[...]

After leaving BusyBox's menuconfig, the user needs is prompted twice to confirm a default value. Maybe we can skip this automatically / add a note to the tutorial.

@w84death Please reopen this issue so when can discuss minor issues here.

A small note: this fix is required for distros with GCC 14+, not just Arch Linux.

floppinux/floppinux.md

Lines 193 to 199 in f97120d

	> You may skip this following fix if you are building on Debian/Fedora
	Fix for **Arch Linux based distributions**:
	```bash
	sed -i 's/main() {}/int main() {}/' scripts/kconfig/lxdialog/check-lxdialog.sh
	```

@82MHz @4goettma there's still a small bug of missing quotes, that's causing these options to be dropped entirely when you run a build afterwards. I fixed it and made a pull request #15
