i trying debug below c++ program on new mac in eclipse mars.
i able build project (which generates output file).
i able run 'local c++ application' not generate output file seems completing successfully.
but unable debug says ...
i tried different options in 'debug configurations' no luck ...
'could not determine gdb version using command: /usr/bin --version' ...
'no such debugger'
error creating session cannot run program "gdb": unknown reason cannot run program "gdb": unknown reason cannot run program "gdb": unknown reason
could not determine gdb version using command: /usr/bin --version
"error while launching command: gdb --version"
what doing wrong ? appreciated.

apple hasn't shipped gdb tools quite while now. can download , build fsf gdb, have no idea how works on os x. apple added lot of functionality version of gdb shipped in day never made fsf source base.
the debugger apple supports lldb. can use lldb eclipse through lldb-mi driver. doing described instance here:
https://www.codeplay.com/portal/lldb-mi-driver---part-2-setting-up-the-driver
note if have xcode 7.x, includes lldb-mi driver program in xcode.app/contents/developer/usr/bin/lldb-mi, don't have go through steps in 2.1 above.
