static-libraries - 如何将 64 位 COFF 转换为 OMF？

Question

我需要将 64 位 .lib 文件从 COFF 转换为 OMF。 Coff2Omf.exe 适用于 32 位库但给出...

ERROR: COFF error: FOOx64.lib
(coffread.cpp, 1637) : invalid machine type detected

...在 64 位库上。是否有用于此目的的更新工具或类似工具？

根据 Embarcadero 的文档:

Differences Between Clang-based C++ Compilers and Previous-Generation C++ Compilers

Object and Library File Format

• BCC32 and its associated tools use OMF in .obj and .lib files.
• Clang-based C++ compilers use ELF in .o and .a files.

This difference means, for example, that when you migrate a 32-bit Windows applications you must change references to .lib and .obj files to be .a and .o, respectively.

BCC64.EXE, the C++ 64-bit Windows Compiler

Compiled object file
ELF64 format

#pragma link

Do not specify the file extension (.ext) of modulename, as long as you are using default file types. The linkers assume the following default values for the file extension (.ext) of modulename:

• .obj extension for BCC32
• .o extension for:
  Clang-based C++ compilers
  BCCOSX

So if you omit the .ext, then the correct extension is automatically used according to your current target platform.

OMF 仅供 32 位编译器/链接器使用。 64 位编译器/链接器改用 ELF64。
