C++ Eclipse 生成无效的 exe

Question

我正在使用 C++ Eclipse 和 MinGW/MSYS 生态系统来编译我的 C++ 程序。我在我的系统变量中为 MinGW/MSYS 设置了正确的路径。在构建时，还会创建一个名为 LibTest 的 EXE，但它的格式为 x86/le。当我运行这个 EXE 时，出现以下错误:

CreateProcess error=193, %1 is not a valid Win32 application

我在创建的 EXE 上使用了 Dependency walker，但出现了以下错误

Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.

我在下面附上构建日志:

似乎正在挑选一些 32 位库。

但是，如果我使用命令行编译，则会生成正确的 EXE。

Answer 1

问题似乎出在真正使用 -shared 上。 -shared 用于动态链接库(.DLL)仅。对于构建应用程序 (.EXE)，您不应使用它。 (我说的是你的 makefile 中的最后一个命令:g++ -shared -o"libTest.exe"./src/Test.o)

像这样构建

g++ -o "libTest.exe"  ./src/Test.o
