exe convert dll golang

In Golang, you can use cgo technology to convert a dynamic link library (DLL) written in C or C language into a dynamic link library (DLL) in Go language.

Generally speaking, a DLL is an executable file that can be loaded into memory at runtime and used by other programs. During the compilation phase, the code is combined into an executable file through the linker. In some cases, we may need to convert an executable file into a dynamic link library so that the code in it can be reused in other programs.

First, we need to create a dynamic link library containing the C or C code that needs to be converted. This can be done using a C or C compiler and linker. For example, on Windows systems, we can use the Visual Studio toolchain to create a DLL.

Next, we need to create a new Go language program and use CGO technology to call the functions in the DLL and convert them into functions in the Go language. CGO technology allows us to use C language functions and variables in Go language programs.

The following is a simple example that demonstrates how to convert a DLL written in C language to a DLL written in Go language:

// main.go

package main 

/*
#cgo CFLAGS : -I .
#cgo LDFLAGS: -L . -llibrary
#include "library.h"
*/
import "C" 

func main() { 
    C.my_function() 
}

In the above example, we used CGO technology to call the DLL 'my_function' function. In a function signature, 'C' means using the C calling convention. 'CFLAGS' and 'LDFLAGS' are used to specify the paths to search for header files and library files. '#include "library.h"' declares functions that can be used in the Go language.

Then, we need to execute the following commands in the command line to compile and link our program:

go build -o output.dll -buildmode=c-shared main.go

In the above command, the -o option is used to specify the output file name, -buildmode Options are used to specify the type of generated file. In this example, we use the c-shared option to tell the linker to generate a dynamic link library.

Once the command is executed successfully, we will get a DLL file named 'output.dll'. We can use this file to dynamically link the library in other programs.

In short, converting a DLL written in C or C to a DLL in the Go language is a very useful technology that allows us to reuse C or C code in different programs. It requires some CGO technology and C programming knowledge, but once mastered, it will bring us a lot of benefits.
