I'm building the development version of systemd.
After updating various programs listed in the Changelogs for LFS and
BLFS, I left linux-5.5 for last. I had upgraded to linux-5.4.13 a few
days ago, without trouble. Keeping in mind that glibc-2.30 depends on
the linux headers, as stated in the LFS book:
#############
6.7.1. Installation of Linux API Headers
The Linux kernel needs to expose an Application Programming Interface
(API) for the system's C library (Glibc in LFS) to use. This is done by
way of sanitizing various C header files that are shipped in the Linux
kernel source tarball.
#############
I did that sanitizing with linux-5.5, and then built the full linux-5.5.
Unlike earlier builds, the build process asked a bunch of questions
about "makemenu" options, most of which I accepted the default for. Then
I modified the configuration file of the boot manager I use, rEFInd, to
account for the updated linux version. Unfortunately I missed changing
one line that specifies loading the initrd file, which stayed at the one
for linux-5.4.13. I rebooted the system, and everything seemed to be ok.
At least, until I tried to compile Fluxbox.
That complained that a couple of pieces of libstdc++ were missing. After
some research, I decided to recompile glibc, which required redoing the
Linux API Headers stuff first. Then "make" for glibc went into an
endless loop after 3-4 minutes, so I eventually Control-C'd out of it. I
repeated this process several times with the same result. Here's the
repeating part of the loop:

After that, I carefully went over each step of making the Linux API
headers and compiling glibc. I discovered my error of using the old
initrd file in the boot manager configuration file. I fixed that and
rebooted, then again built the API headers for linux-5.5 and then tried
glibc again. I got the same endless loop. Then I tried the same thing
with linux-5.4.13 and glibc, which last week built with no issues. I got
the same endless loop.
Obviously something else has changed, but I have no clue what. Any ideas?
