# Configuration `xds-gdb` configuration is defined by variables (see listed below). These variables may be set using: - environment variables (inherited), - or a config file set with `XDS_CONFIG` environment variable, for example: `XDS_CONFIG=/tmp/my_xds_gdb_config.env xds-gdb` - or by setting variables within a gdb ini file (see details below), - or a "user" config file located in following directory (first found is taken): 1. $(CURRENT_DIRECTORY)/.xds-gdb.env 1. $(CURRENT_DIRECTORY)/../xds-gdb.env 1. $(CURRENT_DIRECTORY)/target/xds-gdb.env 1. $(HOME)/.config/xds/xds-gdb.env ## Configuration Variables `XDS_CONFIG` Config file defining `XDS_xxx` configuration variables. Variables of this file will overwrite inherited environment variables. Variables definition may be prefixed or not by "export" keyword. Here is an example of config file: ```bash cat $HOME/myProject/xds-gdb.env export XDS_AGENT_URL=http://localhost:8800 export XDS_PROJECT_ID=4021617e-ced0-11e7-acd2-3c970e49ad9b export XDS_SDK_ID=c226821b-b5c0-386d-94fe-19f807946d03 ``` `XDS_LOGLEVEL` Set logging level Supported levels: - panic - fatal - error - warn - info - debug `XDS_LOGFILE` Set logging file, default `/tmp/xds-gdb.log`. `XDS_NATIVE_GDB` Use native gdb mode instead of XDS mode. `XDS_PROJECT_ID` *(mandatory in XDS mode)* Project ID you want to build `XDS_RPATH` Relative path into project `XDS_SDK_ID` *(mandatory in XDS mode)* Cross Sdk ID to use to build project `XDS_AGENT_URL` Local XDS agent url (default `http://localhost:8800`) ## Configuration variables set within gdb init command file Above `XDS_xxx` variables may also be defined within gdb init command file (see --command or -x option of genuine Gdb). You must respect the following syntax: commented line including `:XDS-ENV:` tag Example of gdb init file where we define project and sdk ID: ```bash # :XDS-ENV: XDS_PROJECT_ID=4021617e-ced0-11e7-acd2-3c970e49ad9b # :XDS-ENV: XDS_SDK_ID=c226821b-b5c0-386d-94fe-19f807946d03 ```
