Go ZeroMQ: Linker problem when trying to build in VS Code on Windows
问题
简而言之，我想做以下事情：
使用https://github.com/pebbe/zmq4并在Windows上的VS Code中运行一个简单的示例，比如hello world。
在构建过程中，我遇到了以下类型的错误：
<Windows Homedir>/TDM-GCC-64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: $WORK\b299\_x008.o: in function `zmq4_bind':
<GOPATH>/pkg/mod/github.com/pebbe/zmq4@v1.2.9/wrappers_windows.go:27: undefined reference to `__imp_zmq_bind'
到目前为止，我做了以下工作：
- 安装了Visual Studio，因为vcpkg install要求安装它。
- 使用
vcpkg.exe install libzmq:x64-windows安装了libzmq（默认是32位安装，我之前错误地安装了它，希望没有残留导致问题）。 - 在VS Code终端（PowerShell）中设置了所需的Go环境变量。经过一些尝试，我觉得应该这样做：
go env -w CGO_CFLAGS='-I <Windows Homedir>\vcpkg\installed\x64-windows\include'
go env -w CGO_LDFLAGS='-LD:<Windows Homedir>\vcpkg\installed\x64-windows\lib -L:libzmq-mt-4_3_4.lib'
- 安装了TDM-GCC。
- 将
<Windows Homedir>\TDM-GCC-64\bin、<Windows Homedir>\vcpkg\installed\x64-windows\lib和<Windows Homedir>\vcpkg\installed\x64-windows\include添加到%Path%环境变量中。
我正在使用Go版本go1.18.4 windows/amd64和Windows 10 Enterprise上的VS Code 1.74.1。
我不知道接下来该尝试什么，所以非常感谢任何提示。

In short, I want to do the following thing:
Use https://github.com/pebbe/zmq4 and run a simple example, like hello world in VS Code on Windows.
When building, I get these kinds of errors
<Windows Homedir>/TDM-GCC-64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: $WORK\b299\_x008.o: in function `zmq4_bind':
<GOPATH>/pkg/mod/github.com/pebbe/zmq4@v1.2.9/wrappers_windows.go:27: undefined reference to `__imp_zmq_bind'
What I did so far:
- Install Visual Studio, since it was required by vcpkg install
- Install libzmq using
vcpkg.exe install libzmq:x64-windows(default is 32 bit installation, which I did first by mistake. I hope there is no leftover from this somewhere that's causing problems.) - Set the required Go environment variables in VS Code Terminal (PowerShell). After some trying, it seemed to me that this has to be done like this:
go env -w CGO_CFLAGS='-I <Windows Homedir>\vcpkg\installed\x64-windows\include'
go env -w CGO_LDFLAGS='-LD:<Windows Homedir>\vcpkg\installed\x64-windows\lib -L:libzmq-mt-4_3_4.lib'
- Install TDM-GCC
- Add
<Windows Homedir>\TDM-GCC-64\bin,<Windows Homedir>\vcpkg\installed\x64-windows\liband<Windows Homedir>\vcpkg\installed\x64-windows\includeto %Path% environment variable
I'm using Go version go1.18.4 windows/amd64 and VS Code 1.74.1 on Windows 10 Enterprise.
I have no clue what to try next, so any hints are very much appreciated.

我在链接器标志的语法上犯了一个错误。https://github.com/pebbe/zmq4让我走了一条错误的路。应该是CGO_LDFLAGS=' -L <Windows Homedir>/vcpkg/installed/x64-windows/lib -l libzmq-mt-4_3_4'。
英文:
I was using a wrong a wrong syntax for the linker flags. https://github.com/pebbe/zmq4 has lead me on a wrong track. It should be CGO_LDFLAGS='-L <Windows Homedir>/vcpkg/installed/x64-windows/lib -l libzmq-mt-4_3_4'
