go get "github.com/gbin/goncurses" fails--invalid flag in pkg-config

[richard thiebaud]

go 1.13  Linux mint 20.2:

dick@dick2:~$ go get "github.com/gbin/goncurses"
go build github.com/gbin/goncurses: invalid flag in pkg-config --libs: -Wl,-Bsymbolic-functions

Wouldn't it make more sense to open an issue against that project? Although, since it hasn't seen any updates in eight years you'll probably not get much support. Perhaps try the project it was forked from since it appears to be actively maintained? https://github.com/rthornton128/goncurses

Is this an error in the project?

Yes, although technically it seems to be a problem with the pdcurses/ncurses dependency. The Go toolchain doesn't provide the pkg-config file. That's from the CGO dependency. See, for example, https://github.com/gbin/goncurses/blob/master/defs.go

Note that I think the reported problem about -Wl,-Bsymbolic-functions
will not happen with Go 1.16 or later.

It turns out that the bad options were in the pkg-config for ncurses on my computer. Once I deleted them from the pkg-config files for ncurses and all related items, the problem went away and github.com/gbin/goncurses worked as expected.
