未定义的引用“__imp_fmi2_import_free”

Question

我一直在试图编译和链接C编写的测试文件，并可以与JModelica的FMILibrary通信。我能够编译和链接，并在Linux系统中运行它。即将在Windows中，我使用的MinGW-64编译器来编译和链接FMILibrary测试文件，但我正在逐渐未定义引用错误。我能够编译和32位MinGW的运行它，但我需要编译和64位编译的二进制文件链接。

我的命令是这样的：

gcc -I <..fmilib\include> -L <..fmilib\lib> -lfmilib -o testfile testfile.c fmivars.c 

而下面的是，这是获得打印出来的结果结果

有没有在FMILibrary设置在Windows 64位MinGW的编译器64位编译任何宏或什么？谢谢。

假设libfmilib.x.y.z提供缺少的符号，则链接的/编译器的命令行上的库将其移动到需要他们.C-文件的权利

gcc -I <..fmilib\include> -L <..fmilib\lib> -o testfile testfile.c fmivars.c -lfmilib

谢谢大家对我的帮助。我终于解决了我的问题，并能运行代码。我安装的Dependency Walker通过@PilouPili的建议，并发现我的申请正在寻找在同一个文件夹中的库（我不知道出于某种原因），它是无法找到它。所以，我复制所有的静态和动态库，我在我的testfile的是文件夹中粘贴。还我改变命令行由@alk的建议和移动-lfmilib到最后。我用一个静态的动态库来代替。但不管怎么说我的应用程序现在运行。非常感谢你的帮忙。
