How to Successfully Compile gopacket on Windows 64-bit: A Step-by-Step Solution

Compiling gopacket on Windows 64-bit: A Comprehensive Guide

Problem:

Unable to compile gopacket on Windows 10 in 64-bit mode (GOARCH=amd64), despite successful compilation in 32-bit mode (GOARCH=386). The error encountered is:

c:/WpdPack/Lib/x64/wpcap.lib: error adding symbols: File in wrong format
collect2.exe: error ld returned 1 exit status

Solution:

To successfully compile gopacket on Windows 64-bit, the following steps are essential:

Install Required Components:
- Install go_amd64 and add it to your PATH.
- Install TDM GCC x64 and add its binaries to your PATH.
- Add TDM-GCCx86_64-w64-mingw32bin to your PATH.
- Install Winpcap.
Generate Missing Static Libraries:
- Download the Winpcap Developers' Pack and extract it to C:.
- Copy wpcap.dll and packet.dll from c:windowssystem32 to a temporary folder.
- Generate .def files by running gendef wpcap.dll and gendef packet.dll.
- Create libwpcap.a and libpacket.a static libraries using dlltool commands:
  - dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libwpcap.a --input-def wpcap.def
  - dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libpacket.a --input-def packet.def
- Copy both generated .a files to c:WpdPackLibx64.
Compilation:
- With these preparations completed, gopacket should now compile without errors.

Additional Notes:

The provided solution requires the installation of TDM GCC x64, which provides necessary tools for 64-bit compilation on Windows.
Copying wpcap.dll and packet.dll to a temporary folder is essential as Admin privileges may be required to run gendef on them in their system locations.
Ensure that all paths are correctly set and that necessary variables (e.g., GOARCH) are appropriately specified.
