## Introduction
This readme covers the **optional** feature to use GENIVI DLT (Diagnostic Log and Trace)
for logging withiin gPTP. General information about GENIVI DLT can be found at:
Primary DLT site:
https://at.projects.genivi.org/wiki/display/PROJ/Diagnostic+Log+and+Trace
DLT on GitHub:
https://github.com/GENIVI/dlt-daemon
## Build Related
DLT support in gPTP is a build time option.
### DLT must be built separately first before it can be used within gPTP.
- Get the latest DLT from github
- https://github.com/GENIVI/dlt-daemon.git
- Follow instructions in INSTALL file.
- For example (Building with Shared libraries off)
- mkdir build
- cd build
- cmake -DBUILD_SHARED_LIBS=OFF ..
- make
- sudo make install
- Install places static lib in: /usr/local/lib/x86_64-linux-gnu/static/libdlt.a
- Install places header files in: /usr/local/include/dlt/dlt.h
### Building gPTP with DLT loggging enabled.
- May need to update the gptp Makefile to specify location of DLT headers and lib
- GENIVI_DLT=1 make gptp
## Running
### DLT
- See the DLT documentaion about how to run the dlt-daemon.
- For example
- dlt-daemon -d
- Runs the daemon
- dlt-receive -a localhost
- Simple test client included in DLT to recieve DLT messages.
- dlt-user-example "Test message"
- Test the DLT client and daemon.
### gPTP
- Run as normal.
