=== GCC now uses Implicit DSO linking ===

Key points:
[[Category:Documentation beats]]
# 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.
 
For additional details refer to the feature page on the wiki [[Features/ChangeInImplicitDSOLinking]]
 
=== _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.
