KeyView 23.4

# Software Dependencies

To run KeyView on Windows requires the Microsoft Visual C++ 2019 redistributables to be installed. The redistributables are provided in the `vcredist` folder of the KeyView SDK but you can download the latest installers from Microsoft to get the latest security, reliability, and performance improvements.

To run KeyView on 64-bit Linux requires `libstdc++.so.6` and `libgcc_s.so.1` from GCC 7.2. For your convenience, these are provided in the `bin` folder of your KeyView installation.

NOTE: If you are running KeyView out-of-process then the `servant` and `WKOOP.exe` executables must be able to link to `libstdc++.so.6` and `libgcc_s.so.1`.

- If these are installed in a system folder, like `/lib64`, KeyView will find them automatically.
- If you prefer you can add the path of the folder containing these libraries to the environment variable `LD_LIBRARY_PATH`.

If you are running KeyView in-process:

- If your application is already linking to `libgcc_s` and `libstdc++` from GCC 7.2 or later, KeyView will use them as well and no further action is needed.
- If your application is linking to earlier versions of `libgcc_s` and `libstdc++`, OpenText recommends that you upgrade those binaries to those from GCC 7.2 or later.
- If your application is not linking to `libgcc_s` and `libstdc++` you must ensure those binaries are available in the same way as described in the instructions, above, for running KeyView out-of-process.

If older versions of `libgcc_s` and `libstdc++` are provided (but at least those from GCC 4.8) then most features will continue to work, but PDF Export, Optical Character Recognition, and RMS Decryption will not.

Some KeyView components require specific third-party software:

- On Linux platforms you must install the following dependencies, which are required by the embedded browser (WKOOP):

  RHEL 7 / CentOS 7 | RHEL 8 | SLES 15
  --- | --- | ---
  `libatomic libX11 libXtst libXScrnSaver libXcomposite atk at-spi2-core at-spi2-atk cups cairo pango alsa-lib-devel pciutils-libs` | `libatomic libX11 libX11-xcb libXtst libXScrnSaver libXcomposite atk at-spi2-core at-spi2-atk cups cairo pango alsa-lib-devel pciutils-libs` | `libatomic1 libX11-6 libXtst6 libXss1 libXcomposite1 at-spi2-core cups libcairo2 libpci3`

  For example, on CentOS 7:

  `sudo yum install libatomic libX11 libXtst libXScrnSaver libXcomposite atk at-spi2-core at-spi2-atk cups cairo pango alsa-lib-devel pciutils-libs`

- Java Runtime Environment (JRE) or Java Development Kit (JDK) version 7 to 17 is required in the ExportSDK for outputting to raster graphic images on non-Windows platforms in the Export SDK.
