I believe the readline error will be fixed by re-running cygwin's setup.exe and installing the libreadline-devel package.

As for the FIONREAD error, I'll look into that now and try figure out which package it belongs to and get back to you.

gurcei commented 8 years ago

The only other mystery left is what package is needed for that "FIONREAD" stuff...

I used grep inside my cygwin's "/usr/include" folder to try locate which include-files refer to this FIONREAD...

I then use a 'cygcheck' tool to figure out which packages those include files referred to.

The tool reports that the likely packages needed are:

cygwin64

I'm guessing this one comes with a default install and you should already have this

cygwin64-w32api-headers

while I don't recall manually installing this package, I'm guessing it got installed on my system due to being a pre-requisite to some other package I installed in the past on my cygwin system.

Anyway, try running cygwin's setup.exe and installing that latter package, and hopefully that FIONREAD error will go away too. If not, let me know and we can investigate it further.

Search led me here first; found a solution over at sourceforge. Just wanted to drop a link for the next person who gets stuck with FIONREAD when compiling some C on cygwin: Serial Port Programming in C++

Possible solution: #ifndef FIONREAD // cygwin defines FIONREAD in socket.h instead of ioctl.h #include <sys/socket.h> #endif

Think some solutions have been documented on this ticket, so closing.
