Use go tool compile to create object files and go tool link to combine them into an executable binary.
Use go tool compile to compile Go source files into object files and go tool link to link those object files into an executable. These low-level tools are typically invoked by the go command but can be run directly for fine-grained control.
go tool compile -o main.o main.go
go tool link -o myapp main.o
The compile step translates .go files into .o object files, while the link step combines them with dependencies into a final binary.
Think of go tool compile as the translator that turns your Go code into machine instructions, and go tool link as the assembler that stitches those instructions together into a single runnable program. You usually don't need to run these manually because the standard go build command handles both steps automatically. Use them directly only if you need to debug the build process or customize the compilation pipeline.
