+ bool "Build the shared library loader with debugging support"
+ depends on BUILD_UCLIBC_LDSO
+ default y
+ help
+ Answer Y here to enable all the extra code needed to debug the uClibc
+ native shared library loader. The level of debugging noise that is
+ generated depends on the LD_DEBUG environment variable... Just set
+ LD_DEBUG to something like: 'LD_DEBUG=token1,token2,.. prog' to
+ debug your application. Diagnostic messages will then be printed to
+ the stderr.
+
+ For now these debugging tokens are available:
+ detail provide more information for some options
+ move display copy processings
+ symbols display symbol table processing
+ reloc display relocation processing; detail shows the relocation patch
+ nofixups never fixes up jump relocations
+ bindings displays the resolve processing (function calls); detail shows the relocation patch
+ all Enable everything!
+
+ The additional environment variable:
+ LD_DEBUG_OUTPUT=file
+ redirects the diagnostics to an output file created using
+ the specified name and the process id as a suffix.
+
+ An excellent start is simply:
+ $ LD_DEBUG=binding,move,symbols,reloc,detail ./appname
+ or to log everything to a file named 'logfile', try this
+ $ LD_DEBUG=all LD_DEBUG_OUTPUT=logfile ./appname
+
+ If you are doing development and want to debug uClibc's shared library
+ loader, answer Y. Mere mortals answer N.

+ default y
+ help
+ Answer Y here to if you find the uClibc shared library loader is
+ crashing or otherwise not working very early on. This is typical
+ only when starting a new port when you havn't figured out how to
+ properly get the values for argc, argv, environ, etc. This method
+ allows a degree of visibility into the very early shared library
+ loader initialization process. If you are doing development and want
+ to debug the uClibc shared library loader early initialization,
+ answer Y. Mere mortals answer N.
