不是吗

我遗漏了什么？

尽管MinGW-w64 Wiki上的页面声称项目提供了双目标编译器，但这已不再完全正确。SEH变体（从GCC 4.8.0开始）只是单一目标。您可以通过检查其发行版的目录结构来查看它，也就是说，它们只包含64位或32位寻址的库，但不能同时包含这两个库。此外，最近它在MinGW builds的邮件列表中得到确认

另一方面，普通的旧SJLJ分布确实是双重目标。如果您得到：

应用程序无法正确启动（0xc000007b）。 单击“确定”关闭应用程序

---

当运行这些发行版生成的64位应用程序时，您应该记得

0xC000007B

是

状态\u无效\u图像\u格式

的代码，这是64位应用程序试图加载32位DLL的一个很好的证据。您可能已经将

\bin

添加到

路径

，而应该添加

\i686-w64-mingw32\lib64

，以使64位应用程序正常运行。

对于那些在linux上使用mingw获得此链接器错误的用户，您可能正在尝试使用带有-m32标志的64位编译器构建32位二进制文件，或者以其他方式构建32位二进制文件

---

要解决此问题，只需使用

i686-w64-mingw32

而不是

x86\u 64-w64-mingw32

编译即可。我认为唯一的双目标MinGW-w64构建是。MinGW版本的所有变体似乎都是单目标的，但我可能错了。@Haroogan:MinGW版本不是声称是双目标的吗？嗯，是的，根据这一页，看起来是这样的。但是你得到的结果是可疑的。您是否检查过发行版是否在两种变体（32位和64位）中都包含所有这些库？@Haroogan：老实说，我从来都不了解GCC中的库查找系统是如何工作的。。。它似乎只在文件夹中查找库，而文件夹是硬编码的，所以即使我将库从另一个GCC复制到另一个架构文件夹中，它似乎也不会工作。我只是对正在发生的事情、包含的内容和不包含的内容感到困惑，这就是问题所在。根据错误，LIB不存在，但我没有进一步检查。您下载了SEH变体吗？这是为我做的，谢谢！我在g++标志中添加了-i686-w64-mingw32标志。

gcc-x86_64-w64-mingw32 helloworld.c

give language not recognized error，

gcc-i686-w64-mingw32 helloworld.c

gavea`unrecognized command line option`。我使用的是Windows7 64位上mingw发行版的gdb、gcc和g++。（1） gdb被配置为“i686-pc-mingw32”（2）gcc.exe（x86_64-win32-seh-rev201506，mingwpy build）4.9.2（3）g++.exe（x86_64-win32-seh-rev201506，mingwpy build）4.9.2。所以交叉编译时，

Path

环境变量中不可能有

bin

目录？这是一个很大的限制，我想。。。谁总是想使用绝对路径访问

g++

等。？
