GCC library linker problems

[Eric Fattah <freediver991@xxxxxxxx>]

I have spent more than three full days trying to debug a library linker problem.
  
  My project has custom start up code, and I must use -nodefaultlibs  -nostartfiles, in order to prevent conflicts with automatic startup  code.  
  
  Thus, I need to manually add libraries.  I am working within Eclipse and don't have the option of a custom makefile.
  
  If I try to use functions such as cos(x) or sprintf(), I get a huge  list of unresolved references.  I have added every library I am  aware of, without success.  Below is a dump.
  
  Any help would be greatly appreciated.
