IRAF failed to build on OS X 13.3 (latest Xcode and Developer Tools installed):

cc -c -O -w  -g -Wall -O2  -I/opt/iraf/iraf/include -DNOVOS sysdep.c

build.1.log

Adding #include "unistd.h" (to unix/f2c/src/sysdep.c) seems to fix this issue, but unfortunately a linker issue pops up later on:

build.2.log

Since I've a running IRAF installation on my M1-MacBook (build and compiled in 2022) I retried with those sources ... same error (build.1.log) as above:-( From this I would guess that these issues are somehow related to XCode and Developer Tools (tried to build with 14.3 and 14.2). Anybody else experiencing problems with a fresh installation on Ventura 13.3?

Do I miss something from the logs?

I can confirm this and also went into this problem today after I updated XCode. It seems that the updated clang
is a bit more picky now. Unfortunately, I don't have constant access to a Mac, so it may take a while to fix it.

I converted this to bug report #273

At first sight it looked like patching iraf.h (adding #include <string.h> and #include <stdlib.h>) might fix the linker issues, but there are plenty more (like fe this one:
