PrestoPlot on a 64-bit Linux

If PrestoPlot fails to start on a Linux 64-bit machine, check for an error message in the Broker log tab. PrestoPlot is a 32-bit binary so it might return the following message :

PrestoPlot : Apps/PrestoPlot/bin/prestoplot.lnx: error while loading shared libraries: libX11.so.6: cannot open shared object file: No such file or directory

  • Install the libX11 library with its dependencies (libXau, libxcb) in a 32-bit version. On yum-based systems, type:

sudo yum install libX11.i686

Celestia dependencies on Linux

If Celestia fails to start, the libpng 1.2 library might be missing.

  • Install the libpng12 library. On yum-based systems, type:

sudo yum install libpng12
