Building on Windows

Setting up the Environment to compile on Windows

Requirements

• Microsoft Windows
• Microsoft Visual Studio (Express or Other)
• Window Driver Kit
• MinGW and MSYS
• libgpgme source
• libgpg-error source
• libassuan source

Setting up the build environment

In order to compile the plugin, you need to compile libgpgme and libgpg-error, and crate the .lib files.

build and install libassuan

1. Extract libassuan somewhere

2. In the MSYS CLI, navigate to the libassuan dir and execute:

    ./configure --prefix=/mingw
    make
    make install
   

build and install libgpg-error

1. Extract libgpg-error somewhere

2. In the MSYS CLI, navigate to the libgpg-error dir and do

    ./configure --prefix=/mingw
    make
    make install
    mkdir lib
    cp src/.libs/libgpg-error-0.dll.def lib/libgpg-error-0.def
   

3. For the next part, either you need to be in the standard windows CLI (cmd.exe) or in the visual studio command prompt.

   3.1 if using the Visual Studio CLI, cd to your libgpg-error directory and type:

    lib.exe /machine:i386 /def:lib\libgpg-error-0.def /out:lib\libgpg-error-0.lib
   

   3.2 if you use the standard windows CLI (cmd.exe), go to the libgpg-error directory and type:

    c:\WinDDK\7600.16385.1\bin\x86\x86\link.exe /lib /machine:i386 /def:lib\libgpg-error-0.def /out:lib\libgpg-error-0.lib
   

4. move the file lib/libgpg-error-0.lib somewhere that the compilier can find it while building the plugin.

build and install libgpgme

1. Extract libgpgme somewhere

2. In the MSYS CLI, navigate to the libgpgme dir and do

    configure --prefix=/mingw
    make
    make install
    mkdir lib
    cp src/.libs/libgpgme-11.dll.def lib/libgpgme-11.def
   

3. For the next part, either you need to be in the standard windows CLI (cmd.exe) or in the visual studio command prompt.

   3.1 if using the Visual Studio CLI, cd to your libgpg-error directory and type:

    lib.exe /machine:i386 /def:lib\libgpgme-11.def /out:lib\libgpgme-11.lib
   

   3.2 if you use the standard windows CLI (cmd.exe), go to the libgpg-error directory and type:

    c:\WinDDK\7600.16385.1\bin\x86\x86\link.exe /lib /machine:i386 /def:lib\libgpgme-11.def /out:lib\libgpgme-11.lib
   

4. Move the file lib/libgpgme-11.lib somewhere that the compilier can find it while building the plugin.

Build the plugin

1. Navigate to the webpg-npapi directory and execute:

   1.1 For Visual Studio 2008:

    firebreath\prep2008.cmd . build
   

   1.2 For Visual Studio 2009:

    firebreath\prep2009.cmd . build
   

   1.3 For Visual Studio 2010:

    firebreath\prep2010.cmd . build
   

2. Navigate to the newly created build directory and execute:

    cmake --build . --config MinSizeRel --target webpgPlugin
   

The plugin is now built, and should be found in build\bin\webpgPlugin\MinSizeRel\npwebpgPlugin.dll
