Hi Eliot,

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?


$ 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.

$ uname -a
CYGWIN_NT-10.0-19045 DESKTOP-P3E71RB 3.4.5-1.x86_64 2023-01-19 19:09 UTC 
x86_64 Cygwin

$ cygcheck -f /usr/include/sys/select.h
cygwin-devel-3.4.5-1
