error while loading shared libraries: libjpeg.so.62: cannot open shared object file:
No such file or directory
The Required Shared Libraries
In order for printing to succeed, certain libraries must be installed on the middle tier where SAS Visual Analytics is deployed. Here is a list of known libraries. Depending on your release of SAS Visual Analytics, the version number at the end of the library name might be different. The transport log indicates exactly which library is missing, so you should install the library indicated in the log. The example messages shown previously appeared because the libjpeg.so.62 library was not installed in a SAS Visual Analytics 7.1 environment.
- libjpeg.so.62
- libfreetype.so.6
- libpng12.so.0
- libfontconfig.so.1
- libz.so.1
- libm.so.6
- libpthread.so.0
- libc.so.6
- libexpat.so.1
- libXxf86vm.so.0
- libcurl.so.4
- libXdamage.so.1
- libxcb-shape.so.0
Note: The transport log mentions only the first missing package that it finds. Continue to check the log until you no longer see a message about a missing library.
The packages that provide these shared libraries differ by Linux version and distribution. Both the yum (Red Hat Enterprise Linux and Oracle Linux) and zypper (SuSE Linux Enterprise Server) commands provide options for finding the package that contains a particular file. For more information about finding and installing the required packages, consult the man pages for yum and zypper, and the documentation for your Linux distribution.
