=== GCC now uses Implicit DSO linking ===
 
Key points:
# ld will no longer automatically search in the dependencies of linked objects.
# If your project used both libraries A and B, it will not compile unless A and B are both explicitly linked.
# There are more explanations on the Features page. [[UnderstandingDSOLinkChange |here]]
 
Under the new changes, if your package fails its build with a message like:
 
  /usr/bin/ld: gpx-parser.o: undefined reference to symbol 'acos@@GLIBC_2.0'
  /usr/bin/ld: note: 'acos@@GLIBC_2.0' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line
 
 
Then the line that builds the specified .o needs to explicitly link libm.
 
 
 
=== _builtin_stdarg_start has been completely removed from GCC 4.4.3 ===
 
_builtin_stdarg_start will return a undefined reference to "_builtin_stdarg_start" because of the depreciation of <stdarg.h> in GCC 4.0
The replacement is _builtin_va_start.
