| # How to Debug |
| |
| --- |
| |
| Since SINGA is developed on Linux using C++, GDB is the preferred debugging |
| tool. To use GDB, the code must be compiled with `-g` flag. This is enabled by |
| |
| ./configure --enable-debug |
| make |
| |
| ## Debugging for single process job |
| |
| If your job launches only one process, then use the default *conf/singa.conf* |
| for debugging. The process will be launched locally. |
| |
| To debug, first start zookeeper if it is not started yet, and launch GDB |
| |
| # do this for only once |
| ./bin/zk-service.sh start |
| # do this every time |
| gdb .libs/singa |
| |
| Then set the command line arguments |
| |
| set args -conf JOBCONF |
| |
| Now you can set your breakpoints and start running. |
