交叉编译probem - rdynamic

如何解决交叉编译probem - rdynamic

我一直在尝试在 wsl2 上将库 libsound 交叉编译到 Windows 10。

我使用了 library's github 中描述的步骤。会议“为 Windows 构建”

但是，我在 cmake 执行过程中遇到了一些问题：

cmake .. -DCMAKE_TOOLCHAIN_FILE=/path/to/mxe/usr/x86_64-w64-mingw32.static/share/cmake/mxe-conf.cmake

命令返回：

  is not able to compile a simple test program.

  It fails with the following output:

我遵循了 github 中描述的所有说明。

有人知道这是怎么回事吗？

解决方法

我认为使用兼容 MinGW 的 GCC 构建的应用程序是兼容 Windows 的应用程序，但我不确定。 -rdynamic 仅与 Linux / ELF 目标相关。您可能需要确保指定了正确的编译器，例如通过设置 CC 环境变量。
