GCC8.2-Chapter6 LFS test check
 
Hello,

I am building Linux from scratch following the book instructions from Linux-From-Scratch-Version8.3-systemd Page#123. I am in the GCC package now and while running the following command
Code:
chown -Rv nobody .
su nobody -s /bin/bash -c "PATH=$PATH make -k check"
I get the following output:
Code:

I want to know if I am good to go and install the GCC package or am I missing something? Also, I did all the previous steps with no errors and in a single mount i.e. I have not disconnected my partition drives or shut any system etc. So I believe, there is nothing wrong with mounting the virtual drives.

Thanks,

Looks good to me. The lines
Code:
make: *** [Makefile:2235: do-check] Error 2
make: Target 'check' not remade because of errors.
always occur if there is even one "unexpected" failure. But I can't even see one on your output. There are plenty of expected failures but they don't count. Anyway, one or two errors in a program as complex as gcc is to be expected. That's a general rule, by the way. One error is no cause for panic. A lot of them means something is wrong. Go ahead and install.

Sorry to piggyback on this thread
when I run
Code:
chown -Rv nobody .
su nobody -s /bin/bash -c "PATH=$PATH make -k check"
I get the message
Code:
su: cannot drop the controlling terminal
any ideas?

My guess is something wrong with either /dev or /dev/pts. You don't say whereabouts in the book you are, but if you are in chapter 6, then everything depends on the correct dynamic filesystems being mounted on the new LFS partition before you chroot. Especially if you are working in spasms on different days. I always use a script to do all the mounts and then chroot, so I don't have to remember the details.

Try ls /dev and ls /dev/pts to check that all your devices are there

ta for the reply. I've re-mounted everything, deleted gcc-8.2.0 and am trying again!

I ran into this same issue (4 years later!) in v11.2 of the book, which uses the "tester" account instead:

Code:
chown -Rv tester .
su tester -c "PATH=$PATH make -k check"
I also tried rebooting and remounting everything, re-entering the chroot. The issue ended up being something wrong with the root permissions.

Code:
(lfs chroot) root:/sources/gcc-12.2.0/build# ls -ld /
drwx------ 20 1001 1000 4096 Nov 24 16:44 /
The fix was to set these permissions to the same as /bin/bash:
Code:
chmod 755 /
