LFS on a VM

发表于 分类于 阅读次数： 本文字数： 3.8k 阅读时长 ≈ 3 分钟

Just without vmware-guest-additions support, so there is no Internet.

FAQs & tips

I'm lazy, I don't want to create any other partition including /home, /boot or create swap.

Yes, you can expand your VM disk by 20 GB and allocate it to your LFS root directory. Using the /boot directory from your host distro is acceptable (even it's not in a seperate partition).

sed: can't read gcc/config/i386/t-linux64: No such file or directory

https://www.linuxquestions.org/questions/linux-from-scratch-13/sed-can%27t-read-gcc-config-i386-t-linux64-no-such-file-or-directory-4175694927/

You didn't extract the tarball and enter the gcc directory, the LFS guide omitted these first two steps every page.

VMware Workstation has paused this virtual machine because the disk on which the virtual machine is stored is almost full

Read the warning carefully, it says:

VMware Workstation has paused this virtual machine because the disk on which the virtual machine is stored is almost full.

So it's the time to clean your host disk space, instead of insufficient space of your VM, especially you've taken too many snapshots.

The system has no more ptys. Ask your system administrator to create more.

Make sure if you've done chapter 7.3 and chapter 7.4 correctly. You can save the script below in your VM, reboot and run it with root privilege.

chroot "$LFS" /usr/bin/env -i   \
    HOME=/root                  \
    TERM="$TERM"                \

The terminal looks frozen when running make check in gcc of chroot environ

That's normal. The guide says it takes around 43 SBU to finish the whole process. For me it cost about 10 hours without pipelining, some of checks like asan.exp in g++ tests, comformance.exp in libstdc++ tests cost 2 to 3 hours (yes, for one check file).

You can type su tester -c "PATH=$PATH make -k check -j4" to speed up a bit.

Make failure in gcc of chroot environ

Try make again (without -B).

Too many make check failures (thousands of) in gcc of chroot environ

It's maybe caused by the source, download again in All Packages and redo the process if you want to wait another couple of hours.

If you didn't see any error in make, ignore the make check process is also an option.

Can I use grub-mkconfig in my host distro to generate boot config

Yes, it works. The only flaw is that the grub boot menu entry will be unknown Linux distribution on /dev/sdaX instead of our favorite Linux From Scratch.

Can't boot into LFS, saying something including available partitions: 0b00 1048575 sr0 driver: sr

The Linux kernel you built doesn't include the VMware disk driver. You can search options in make menuconfig which contains string VMWARE and add them manually in .config in kernel source root.

Here are the search results of my machine:

Summary

It tooks me about 9 days, the kernel config is not as hard as I thought before. The most difficult part is the patience.

BTW, the technical guide explained before looks still kind of abstract even though I've finished the whole process. Maybe that's the most educational part in the whole LFS journey.

In the future, maybe I'll go to the BLFS part, such as installing vmware-guest-additions and configuring the network, ssh, programming, DE, etc. Of course this is time-cosuming, so maybe I'll give up here.
