3 years ago Looks like ming-w64 isn't required, all that needs to happen is to set the architecture to x64 on 64-bit platforms. An updated build.gradle is provided below:
// Builds a Ghidra Extension for a given Ghidra installation.
//
// An absolute path to the Ghidra installation directory must be supplied either by setting the
// GHIDRA_INSTALL_DIR environment variable or Gradle project property:
//
// > export GHIDRA_INSTALL_DIR=<Absolute path to Ghidra>
// > gradle
//
// or
//
// > gradle -PGHIDRA_INSTALL_DIR=<Absolute path to Ghidra>
//
// Gradle should be invoked from the directory of the project to build. Please see the
// application.gradle.version property in <GHIDRA_INSTALL_DIR>/Ghidra/application.properties
// for the correction version of Gradle to use for the Ghidra installation you specify.

On windows, trying to mount a uefi filesystem results in the following JNI exception:
I hacked together a
build.gradlefile that will build a working version:Now this hacked-together gradle file might build a working version for windows, but it almost certainly will not work for other operating systems. I'm not a good enough Java/Groovy/Gradle engineer to know how to refactor this to a form that can be committed to the repository, but it took me quite a bit of effort to figure out why the current master branch does not work so I wanted to share my work in case anyone else needs it.
FWIW, I documented what I found here: https://nstarke.github.io/0047-ghidra-firmware-utils-adventure.html
