package main // If a Go source file imports “C”, it is using cgo. The Go file will have access to anything appearing in the comment immediately preceding the line import “C”, and will be linked against all other cgo comments in other Go files, and all C files included in the build process. /* #include stdio.h #include stdlib.h void myprint(char* s) { printf("This is in C code : %s\n", s); } */ import "C" note here: there should be no new line between closing comment (*/) and import “C” lines, like below */ new line import "C" this will result in error, # command-line-arguments could not determine kind of name for C.free could not determine kind of name for C.myprint import "unsafe" func Example() { cs := C.CString("This is passed from Go Code\n") C.myprint(cs) C.free(unsafe.Pointer(cs)) } func main() { Example() } //reference : https://github.com/golang/go/wiki/cgo The complete source code for “main.go” is like below, package main /* #include stdio.h #include stdlib.h void myprint(char* s) { printf("This is in C code : %s\n", s); } */ import "C" import "unsafe" func Example() { cs := C.CString("This is passed from Go Code\n") C.myprint(cs) C.free(unsafe.Pointer(cs)) } func main() { Example() } Compile the code as, go build If you are cross compiling same code, you can refer to post https://lynxbee.com/how-to-resolve-error-no-buildable-go-source-files-in/ and add CGO_ENABLED=1 before go build.

Execution & Command Syntax

Terminalbash
sed from Go Code\n") C

Gotchas and Common Issues

  • Permission Verification - confirm execution permissions and path variables before invoking system binaries.

  • Version Compatibility - check software version release notes for deprecated flags or syntax changes.

  • Log Monitoring - inspect system logs (journalctl or /var/log) to troubleshoot execution failures.

Following these steps ensures clean configuration, proper security boundaries, and reliable execution for execute c code from go – c to golang binding.
