KeyValue is available in standard formats at SourceForge.
Just download and unpack it into your hard disk.
Windows Vista users might need to perform an extra step. As we shall see below, KeyValue's build system relies on Cygwin. For an obscure reason in some but not all machines, Cygwin fails to copy files. To prevent this from happening, turn KeyValue's home directory and all its descendants into shared folders. Right click on KeyValue's home directory and select . Then, click on . Then the directory gets a new icon with a two-people picture.
KeyValue depends on a few libraries and tools. Some of them are compulsory while others depend on the user's purpose. The following sections explain in detail the need for these tools and libraries.
Two C++ compilers are supported: Microsoft Visual C++ 2008 (for Windows) and GCC (for GNU/Linux).
Most of GNU/Linux distributions come with GCC already installed. KeyValue has been tested with version 4.x.x but other versions should work as well.
Microsoft provides different editions of Visual Studio C++ 2008. The Express Edition is available, free of charge, at
Editions differ mainly in their IDEs. However, there are also compiler differences. During KeyValue's development we came across lines of code that the Professional Edition did compile whereas the Express Edition failed. Some effort has been made to maintain compatibility with both editions.
We need additional build tools, notably, GNU make and the bash shell.
GNU/Linux users do not have to worry about most of these tools since they are probably installed by default. However, a less popular tool called makedepend is required. Normally, it is part of the x11 or xorg packages. To check whether you have it or not, on a console window type:
If not found, use your distribution's package system to install it or, alternatively, download and install from source code:
Windows users will also need these tools but, unfortunately, they are not directly available. Therefore, Cygwin (see Section 2.4) will be required to provide a GNU/Linux-compatibility layer to Windows systems.
Boost is a high quality set of C++ libraries for general purposes.
KeyValue depends on a few of Boost libraries notably Smart_Ptr (for shared and intrusive pointers) and Date_Time (for date and time classes). All Boost libraries that KeyValue depends on are header-only. Therefore, all we need is to download and unpack Boost into the hard disk.
Boost is available for download at its SourceForge page:
KeyValue is a cross platform library for GNU/Linux and Windows systems. Its build system relies on tools that are very popular on GNU/Linux systems but not on Windows. For that reason, Windows users must install Cygwin to have a GNU/Linux-like compatibility layer. Cygwin is available at
During installation we have to make a few choices. Normally, default answers are fine. However, when choosing the packages to install, make sure that the following items are selected:
Archive/zip (needed only if we want to build the LibreOffice Calc add-in);
Although installation procedures for KeyValue developers is not in the scope of this document, we anticipate here the list of extra Cygwin packages that developers must install:
Cygwin comes with a small tool called link.exe to create file links (shortcuts). This tool is, probably, useless since there is a Windows native alternative and Cygwin also provides ln for the same purpose. Unfortunately, we must bother with link.exe because this is also the name of the Microsoft Visual Studio linker and, therefore, they conflict. A workaround is renaming Cygwin's link.exe to, say, link-original.exe. Open a bash shell by clicking on and type the command below followed by Enter.
On many occasions we need to type bash shell commands. Therefore, remember how to get a bash shell console window and consider keeping it constantly open while working with KeyValue.
KeyValue comes with a LibreOffice Calc add-in for GNU/Linux and Windows systems. To build this add-in, one must install the LibreOffice SDK.
The LibreOffice Calc add-in has been tested with some 3.x.x versions of LibreOffice and LibreOffice SDK. It probably works with all 3.x.x versions.
Download and install a LibreOffice SDK version compatible with your installed LibreOffice:
KeyValue comes with an Excel add-in. To build this add-in, one must install the Excel SDK.
Only the Excel 2007 API is supported. If compatibility with this API is kept by new Excel releases, then the add-in should work with them as well. However, KeyValue does not work with Excel 2003.
