TSS v15.8 and later versions support Trillium Quality 64-bit processing for Linux only and does not include 32-bit processing. Note the following:
If you have an existing real-time project that was running with the 32-bit modules, the project automatically runs with the 64-bit modules in the current release.
If you have an existing 32-bit client application developed with a pre-v15.8 version, you will need to re-compile it for 64-bit processing. For the 64-bit Director API, only Java is supported and there is no support available for C/C++.
