c++ - 向后的 cpp 无法再构建，尽管链接但仍缺少 lbdf

Question

我在 arch 上并且犯了升级错误。

在我可以构建 bacward-cpp 之前，现在我收到以下错误:

../libraries/backward-cpp/backward.hpp:1357:10: error: ‘bfd_get_section_flags’ was not declared in this scope; did you mean ‘bfd_set_section_flags’?
 1357 |     if ((bfd_get_section_flags(fobj.handle.get(), section) & SEC_ALLOC) == 0)
      |          ^~~~~~~~~~~~~~~~~~~~~
      |          bfd_set_section_flags

      |                        ^~~~~~~~~~~~~~~~~~~
      |                        bfd_set_section_vma

 1361 |     bfd_size_type size = bfd_get_section_size(section);
      |                          ^~~~~~~~~~~~~~~~~~~~
      |                          bfd_set_section_size
make[1]: *** [VulkanEngine.make:233: obj/Debug/VulkanDebugging.o] Error 1
make: *** [Makefile:30: VulkanEngine] Error 2

我通过将 -lbfd -ldl 作为 g++ 的参数来链接 lbdf 和 ldl。在按照文档包含 header 之前，我还在执行 #define BACKWARD_HAS_BFD 1 。

我很茫然。

binutils对应的宏略有变化。

您必须从节宏中删除 _get 并手动删除 fobj.handle.get() 参数:bfd_get_section_flags(fobj.handle.get (), 部分) 到 bfd_section_flags(section)。
