Bzip2 – Visual Studio libbz2.dll Build

Patches and a PowerShell script to build bzip2 with Visual Studio using a dynamic library (libbz2.dll).

Patches

Patches are included in this repository that modify the makefile.msc file in the bzip2 distribution to:

  • Build cleanly with Visual Studio 2013 and later (replacing deprecated command line options).
  • Build libbz2 as a DLL (libbz2.dll).
  • Dynamically link the executable outputs with libbz2.dll (by default the executables are statically linked).
  • Add a version resource to the executables and DLL.
  • Fix a 'not a normal file' error when using bzip2.exe to compress large files.

PowerShell Script

The PowerShell script, Build-Bzip2.ps1, performs the following actions:

  1. Downloads the bzip2 source from https://www.sourceware.org/bzip2/.
  2. Extracts and verifies the source.
  3. Applies the patches (see above).
  4. For the x86 and x64 architectures:
    1. Executes nmake to build bzip2.
    2. Copies build outputs to a directory named outputs.
    3. Creates zipped packages containing build outputs in a directory named packages.

Build-Bzip2.ps1 requires:

Binaries

32-bit and 64-bit Windows binaries can be downloaded from the releases page.

The binary releases depend on the Visual Studio C Runtime Library (please refer to the release notes for details).
