Slirp not supported on mingw build

[DependentAppearance0]

Describe the bug I am trying to use networking in windows 98 and as my wifi adapter doesn't support pcap I'm trying to use slirp. According to all of the documentation slirp isn't supported on the visual studio builds so I reinstalled dosbox-x using the MinGW build SDL1 (Default MinGW build). No matter what I do I get the following lines in my log files:

ETHERNET: Backend not supported in this build: slirp
NE2000: Failed to open Ethernet backend slirp

I did also test the mTCP example which ended up returning the fully FF mac address.

Environment: Windows 10 21H1 DOSBox-X 0.83.15 Used the bellow configuration:

It appears that libslirp may not be enabled in the default MinGW build for some reason, even though in the MinGW script there is supposed to be a step to install the mingw-w64-x86_64-libslirp library for 64-bit MinGW builds. In any case, can you try the following 64-bit MinGW SDL1 build that I compiled myself for Slirp support?

The build you attached works and slirp is able to run. I have full internet access on both dos and windows 98 with the attached build.
