seehuhn / go-ncurses Goto Github PK

package is not compiling.

Reason is ncurses.h does not define KEY_EVENT.

Wrote the necessary ncurses package code on my application and included the import as "seehuhn.de/go/ncurses". Also performed the go get command and up to then no error.

Then when I tried to compile the app in the cmd directory that uses NCurses, I got this go compilation error:

    golang.org/x/sys/internal/unsafeheader
    golang.org/x/sys/unix
    seehuhn.de/go/ncurses
  		Module seehuhn.de/go/ncurses 

		[ FILE  ../pkg/mod/seehuhn.de/go/[email protected]/attrs.go  ]
../pkg/mod/seehuhn.de/go/[email protected]/attrs.go:19@11:
     fatal error  ncurses.h  No such file or directory
       19 | // #include <ncurses.h>
          |           ^~~~~~~~~~~
    compilation terminated.

I have downloaded other modules that required compilation (CGO) and never had an issue, but this one crashed and burned. I am on a Linux Debian (Raspbian).

In ncurses.go there is a CGO line to define the curses library to load. Specifically:

// #cgo LDFLAGS: -lncurses

My tests on modern Debian and FreeBSD show that this now needs to be:

// #cgo LDFLAGS: -lncursesw

to compile successfully.

Have others come across this issue?

It may be that the older library reference is needed for other platforms, in which case this needs to be conditional. But that's an implementation detail.
