Go get with M1 mac fails
When I try to go get the library I'm given the following error. Does this mean that there are system calls being made in the library that are not supported on ARM?

ld: symbol(s) not found for architecture arm64

I'm not familiar enough with M1s to really offer much support. What I do know is that ncurses can be built for the M1s and CGO should work out of box. From the looks of things, though, it strikes me that your system might not have the forms or menu libraries? It might be something similar to: https://gist.github.com/cnruby/960344
I have ncurses programs running on my computer, so you're right that it should be supported. I can compile ncurses programs written in c, with gcc -lform -lncurses so I believe I do have the form library installed, unless it's different for golang. I don't know what the menu library is though, and a google search didn't help.
I don't know how to apply anything in the page you linked to golang because I'm not that familiar with how the compiler works. It seems like the main problem people had there was not having ncurses installed, or not linking it when compiling. I have it installed, but is it possible to link libraries when using go get?
Yes, go get should link them properly. I'm wondering though if your ncurses, specifically the menu and form libraries, are actually natively compiled (ARM64) or are actually Intel. I'm not 100% sure if this will work but you could try setting the architecture for building to AMD64 just to test this theory out:
GOARCH=amd64 go get github.com/rthornton128/goncurses
If that successfully links, that is likely the issue.
I have the same issue, but on a Intel mac. clang -lncurses -lform works perfectly fine.
Hi! I successfully got it working. What happened in my machine was that cgo, somehow, was unable to find the installed libraries. I'm using macos Monterey on a M1 mac and I installed ncurses with brew.
This is what I did: as indicated in this site, ncurses installed by brew doesn't include .pc files (which is true). So here are they!
File: /opt/homebrew/lib/pkgconfig/ncurses.pc
prefix=/opt/homebrew/Cellar/ncurses/6.3
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/ncurses
major_version=6
version=6.3
Name: ncurses
Description: ncurses 6.3 library
Version: ${version}
Requires:
Libs: -L${libdir} -lncurses
Cflags: -I${includedir} -I${includedir}/..
File: /opt/homebrew/lib/pkgconfig/form.pc
prefix=/opt/homebrew/Cellar/ncurses/6.3

Name: panel
Description: ncurses 6.3 add-on
Version: ${version}
Requires: ncurses
Libs: -L${libdir} -lpanel
Cflags: -I${includedir} -I${includedir}/..
With that, I could successfully use pkg-config:
% pkg-config --cflags ncurses form menu ncurses ncurses panel
-I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses -I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses/.. -I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses -I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses/.. -I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses -I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses/.. -I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses -I/opt/homebrew/Cellar/ncurses/6.3/include/ncurses/..
which is nice! So, now I should indicate CGO that these flags should be used when calling the linker. This can be done by setting CGO_LDFLAGS:
export CGO_LDFLAGS="${CGO_LDFLAGS} $(pkg-config --libs ncurses)"
and, voi-lá, it worked :)
My application is indeed very simple - it's just a test to print a character in bold. But I think that this solution might be used if further problems appear, such as missing headers or other libraries.
