我有一些代码,是在golang(在ubuntu上)中编写的,并试图打包为Windows exe,但是不幸的是,由于来自github项目的某些cgo依赖性,我最终不得不按照如下方式将我的程序包构建为dll。回答https://stackoverflow.com/a/49079049/4750381,因为它不能作为Windows的可运行exe文件编译(即使使用MinGw)。
我的编译行是:
[GOOS = windows GOARCH = 386 CGO_ENABLED = 1 CC = i686-w64-mingw32-gcc go build -buildmode = c-shared -o main.dll main.go
我的主程序包代码如下:
package main
import (
"C"
"fmt"
console "github.com/AsynkronIT/goconsole"
"github.com/AsynkronIT/protoactor-go/actor"
"path/to/repo"
)
const cfgPath string = "./config.json"
func main() {
fmt.Println("from main")
}
func dllRun() {
// Used for running the test and various other operations, thus generally all lines except 1 will be commented out
ctx := actor.EmptyRootContext
props := actor.PropsFromProducer(testmachine.NewTestMachine(cfgPath))
pid, err := ctx.SpawnNamed(props, "tm")
if err != nil {
panic(err)
}
defer func() { // run after the read line fucntion executes and terminates the program
ctx.Poison(pid)
}()
console.ReadLine()
}
我编写了另一个go脚本(这次使用Windows)以尝试加载和读取该DLL文件:
import (
"syscall"
)
func main() {
myDLL := syscall.NewLazyDLL("C:/Users/konyenso/Documents/DLLOpener/main.dll")
mainCall := myDLL.NewProc("dllRun")
ret, _, err := mainCall.Call()
if err != nil {
panic(err) // calling myDLL.mainCall failed
}
if ret == 0 {
print("Could not set the desired attributes")
// TODO: call GetLastError to get more information
}
print("OK")
}
但是即使我的文件路径正常,现在也总是出现以下错误:
panic: Failed to load C:/Users/konyenso/Documents/DLLOpener/main.dll: The specified module could not be found.
goroutine 1 [running]:
syscall.(*LazyProc).mustFind(0x13019400)
c:/go/src/syscall/dll_windows.go:311 +0x42
syscall.(*LazyProc).Call(0x13019400, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x4623e0)
c:/go/src/syscall/dll_windows.go:327 +0x21
main.main()
C:/Users/konyenso/Documents/DLLOpener/main.go:11 +0xa5
[有人可以告诉我我在做什么错吗?我整天都在调整,但收效甚微。理想情况下,我想直接从ubuntu构建一个没有dll的exe,但是如果这样做不可行,我至少希望能够从另一个exe文件运行我的dll。感谢您的协助。
**********编辑********************************因此,我编写了一些C ++代码来尝试打开dll文件(两者分别为64位和32位版本)
#define UNICODE
#include <windows.h>
#include <iostream>
/* Define a function pointer for our imported
* function.
* This reads as "introduce the new type f_funci as the type:
* pointer to a function returning an int and
* taking no arguments.
*
* Make sure to use matching calling convention (__cdecl, __stdcall, ...)
* with the exported function. __stdcall is the convention used by the WinAPI
*/
typedef int (__stdcall *f_funci)();
int main()
{
HINSTANCE hGetProcIDDLL = LoadLibrary((LPCWSTR)"C:\\Users\\konyenso\\Documents\\DLLOpener\\main.dll");
if (!hGetProcIDDLL) {
std::cout << "could not load the dynamic library" << std::endl;
return EXIT_FAILURE;
}
// resolve function address here
f_funci funci = (f_funci)GetProcAddress(hGetProcIDDLL, "dllRun");
if (!funci) {
std::cout << "could not locate the function" << std::endl;
return EXIT_FAILURE;
}
std::cout << "funci() returned " << funci() << std::endl;
return EXIT_SUCCESS;
}

您可以从下面的屏幕截图中看到,文件路径匹配,所以我不知道发生了什么。Screenshot showing paths confirmed
首先,您需要这样的导出dll方法:
