| == GCC upgraded in alpha ==
| |
|
| |
| | |
| | |
| | |
| '''Note: gcc has upgraded from 4.4.2 to 4.4.3'''
| |
| This includes gcc, gcc-c++, gcc-fortran, gcc-gnat, and gcc-objc.
| |
| | |
| | |
| '''GCC now uses Implicit DSO linking.'''
| |
| | |
| [[Features/ChangeInImplicitDSOLinking |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.
