Subject: cpp-example: Add std::vector example
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e4e8ff14ab51892bdcb176b9eef2741286597db8;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

cpp-example: Add std::vector example

Add a standard container (std::vector) to the C++ example program to
demonstrate the debugger's capability to inspect and traverse STL
containers during a debugging session. This requires enabling GDB's
pretty-printing feature, which depends on Python scripts shipped with
the compiler.
