I've got a method that is a pain in the ass, but sometimes works.
First, I do a grep so that I can send all the file names that have the unreferenced symbol/function to a file.
For example: grep -rl "_dl_start_final" $PWD > afiletosaveallnames
Then you open "afiletosaveallnames" (doesn't need to be so long) and see whereelse is the unreferenced symbol. Sometimes the function is declared
but not [I]defined[/].
Sometimes is easy, if you find where the function is defined you can add the file to the headers if you find it.
The most of the times the file exists but is misplaced.
If you can't find where the function is defined, then some library is missing.
You 've got to find it somewhere ... and fall in an endless updating..https://lqo-thequestionsnetw.netdna-..._lq/icon12.gif
