I updated Cygwin to 3.4.5-1.x86_64.

However, the same problem occurs.
Cygwn-devel doesn't seem to work.
$ gcc -o selectStdIn selectStdIn.c
selectStdIn.c:9:10: fatal error: sys/select.h: No such file or directory
#include <sys/select.h>
^~~~~~~~~~~~~~
compilation terminated.
Well, on my system cygcheck -f /usr/include/sys/select.h clearly says
that the file came from cygwin-devel-3.4.3-1. Maybe you misspelled
cygwin-devel ? You do have to select the package explicitly, too.
I just reinstalled Cygwin but I'm unsure of what I missed.
I did "cygcheck -f /usr/include/sys/select.h" and it seems to tell me that I
do have cygwin-devel-3.4.5-1
Did I miss a step?
What gcc are you running? Maybe not cygwin's?
I think I'm running MinGW's gcc.
I typed in "gcc --version" and this is what Cygwin returned.
$ gcc --version
gcc.exe (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0

What should I do next?
If you choose to install cygwin-devel in Cygwin Setup, it will install all the
tools and files needed to develop under Cygwin, as well as rebuild Cygwin itself
and most of the components and packages.
If you use the provided Desktop and Start Menu shortcuts to run bash under
mintty, or both under Cygwin/X, you should be able to work as if under any Linux
or similar distro.
You must have the virtual Cygwin paths
/home/$USER/bin:/usr/bin:/bin:/usr/sbin:/sbin:... first in PATH and similar
/usr/share/{man,info,awk} /usr/lib/gawk for {MAN,INFO,AWK,AWKLIB}PATH in your
preferred shell initialization files e.g. in bash $OSTYPE == "cygwin".
