Error for Linux Build

[smalloff]

Hi! My params for Linux release.

set GOARCH=amd64 set GOOS=linux go build -ldflags "-s -w"

Output:

Installed TDM-GCC OS Windows 10. Golang version 1.18.4

How can I compile for Linux? When building for Windows, there are no errors. Thanks!

I have the same error on a docker build.

I have the same error on a docker build.

Try this library github.com/nickalie/go-webpbin

@smalloff @Pukka922 try to add env CGO_ENABLED=1

For me Zig worked great as compiler when cross compiling from Windows to Linux.
I used these env variables:

GOOS=linux
GOARCH=amd64
CGO_ENABLED=1
CC="zig cc -target x86_64-linux-musl"
CXX="zig c++ -target x86_64-linux-musl"
