I think this broke my build. Config params are:

The error I get is in the final linking:
Undefined symbols for architecture x86_64:
"_timer_create", referenced from:
_start_timeout in os_unix.o
"_timer_settime", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
What system is this on?
This is on a Mac running Monterrey (or is it Monterey?)
What is the contents of auto/config.h ?
Specifically the value of HAVE_TIMER_CREATE
/* #undef HAVE_TIMER_CREATE */
I now see that in os_unix.c there is this line:
# if defined(HAVE_TIMER_CREATE) || defined(MACOS_X)
This assumes that any Mac system has timer_create(). Looks like this
isn't true. Can you change that line to:
# if defined(HAVE_TIMER_CREATE)
It looks like this is the only line where this matters.
Also, the contents of auto/config.log where it says "checking for timer_create"
configure:13071: checking for timer_create
configure:13098: gcc -o conftest -g -O2 -I/opt/sw/include -DMACOS_X conftest.c

What is the build command used? Do you overrule $LIBS perhaps?
make
I meant the linker command that gets executed. But considering the
above, it would not matter.
Changing to:
# if defined(HAVE_TIMER_CREATE)
fixed the build.
