Answer 1

By default gcc links dynamically and go - statically.

But if you link you C code statically, you might get a binary with a bigger size.

In my case:

• go x64 (1.10.3) - generated binary with size 1214208 byte
• gcc x64 (6.2.0) - generated binary with size 1421312 byte

both binaries are statically linked and without debug_info.

go build -ldflags="-s -w" -o test-go test.go
gcc -static -s -o test-c test.c
