while building cdrtools there are a bunch of "fatal errors" but without stopping the package to built despite the " | exit 1" at the end the "make ..." line in the cdrtools.SlackBuild.
------------------------
In file included from base64.c:2:
config.h:34:10: fatal error: lconfig.h: No such file or directory
34 | #include "lconfig.h"
| ^~~~~~~~~~~
compilation terminated.

In file included from ioctl.c:2:
config.h:34:10: fatal error: lconfig.h: No such file or directory
34 | #include "lconfig.h"
| ^~~~~~~~~~~
-----------------------
the package builds, despite it should stop on the "fatal error"???

Thanks D. Spaier, I found a solution to build without error:

What has been modified in the slackBuild is this:
---------------------
# When running make below, you'll see "errors" like these:
# config.h:34:10: fatal error: lconfig.h: No such file or directory
# 34 | #include "lconfig.h"
# However, lconfig.h will eventually be generated from lconfig.h.in, the build
# will restart, and the package will be correctly built. Since there are no
# ill effects from this I see no compelling reason to try to patch it here.
make -e INS_BASE=/usr DEFMANBASE=. || exit 1
make -e install INS_BASE=/usr DEFMANBASE=. DESTDIR=$PKG || exit 1
--------------------
the "fatal error" occurs before the generation of lconfig.h

Thanks to PV.

Strange, no fatal errors when I build from source from his master package, though J has gone all weird in recent couple years wanting everyone to use his schillytools and building everything including the kitchen sink that we'll never use nor want now rather than just cdrtools, but you can of course build only individuals from that tree, so anything is possible.

caveat: I last built it
ls -la `which cdrecord`
-rwxr-xr-x 1 root root 525764 Jun 9 2021 /usr/bin/cdrecord*

I guess he has a later version, I'll see if it errors.
