What did you do?

I tryed to compile Discord bot in gccgo. (It can build on gc)
But gccgo errors.

What did you see instead?

What version of gccgo are you using?

Have you tried building using the version of the go tool that comes with gccgo, rather than the version of the go tool distributed with the gc toolchain?

I used Go 1.15.5( https://golang.org/dl/ ) and latest gccgo( https://gcc.gnu.org/git/?p=gcc.git;a=shortlog;h=refs/heads/devel/gccgo )

To use tip gccgo you'll need to use the version of the go tool that comes with gccgo, not the version from the Go 1.15.5 release. (The tip gc release should work also.)

Thank you, I'll try it.
