Using Go Within Existing C Projects
Background:
You have a C program comprised of multiple object files stored in an archive file (.a). You intend to add a new Go file to the project, compile it into an object file, and incorporate it into the existing archive.
Objective:
Integrate Go functions into your C program.
Process:
1. Compile the Go File into an Object File:
Run the following command:
2. Call Go Functions from C:
In your c_caller.c file, declare an extern function:
In the main function, call the Go function and handle the result:
3. Using GCCGO to Build the Entire Project:
Run the following command:
4. Addressing Errors:
Alternative Solution in Go 1.5:
In Go 1.5 (coming in August), a new feature enables the creation of C-compatible libraries from Go code. With this feature, you can build a static or shared library directly from a Go file, eliminating the need for intermediate object files.
Example:
In main.c:
In main.go (compiled with go build -buildmode c-archive ... for static or go build -buildmode c-shared ... for shared library):
