This is a set of scripts for building OpenSlide for Windows, including all of its dependencies, using MinGW-w64.

Cross-compiling from Linux

You will need MinGW-w64, nasm, OpenJDK, and Apache Ant. You will also need the GNU Classpath version of jni.h installed. (On Fedora this is in the libgcj-devel package.)

Then:

./build.sh bdist

Building natively on Windows

One-time setup

1. Install a JDK.

2. Install Cygwin, accepting the default set of packages. Make note of the location of the installer EXE.

3. Launch a Cygwin shell and navigate to the openslide-winbuild directory.

4. Execute:

   ./build.sh setup /path/to/cygwin/setup.exe
   

Building

./build.sh bdist

Note that cross-compiling is much faster than compiling natively.

Troubleshooting

The build will fail if the path to the openslide-winbuild directory contains spaces.

If the build randomly fails complaining that fork() failed due to a DLL address mismatch, follow the instructions here.

Substitute Sources

To override the source tree used to build a package, create a top-level directory named override and place the substitute source tree in a subdirectory named after the package's shortname. A list of shortnames can be obtained by running build.sh with no arguments.

build.sh Subcommands

setup

Configure Cygwin environment. Only useful on Windows. The path to Cygwin's setup.exe must be specified as an argument.

sdist

Build Zip file containing build system and sources for OpenSlide and all dependencies.

bdist

Build Zip file containing binaries of OpenSlide and all dependencies.

clean

Delete build and binary directories, but not downloaded tarballs. If one or more package shortnames is specified, delete only the build artifacts for those packages in the specified bitness.

Options

These must be specified before the subcommand.

-j<n>

Parallel build with the specified parallelism.

-m{32|64}

Select 32-bit or 64-bit build (default: 32).
