| == Boost ==
| |
| | |
| {{package|boost}} provides a set of portable, peer-reviewed, C++ libraries. In Fedora 15, Boost is brought up to date with the current upstream, version 1.4.6. | |
| | |
| With every new release of Boost come new components and libraries. For instance, Boost 1.46 brings ICL, and Boost 1.45 had already brought MSM and Polygon.
| |
| | |
| Moreover, the existing components and libraries are enhanced with new features and bug fixes. For instance, the Boost.Math components have now become better than the GSL for support to statistical analysis.
| |
| | |
| For full details, see the Boost pages at http://www.boost.org/

| == gdb ==
| |
| | |
| Fedora 15 features GDB release 7.3. This, together with [http://sourceware.org/gdb/wiki/ArcherBranchManagement Archer] and Fedora extensions improves debugging experience on Fedora by making the debugger more powerful. The majority of these features were written by Red Hat engineers, thus benefiting all gdb users. New features for the Fedora 15 release are not limited to:
| |
| * Support for breakpoints at [http://sourceware.org/systemtap/wiki/AddingUserSpaceProbingToAppsSystemtap SystemTap markers (probes)]
| |
| * Support for using labels in the program's source
| |
| * OpenCL language debugging support
| |
| * Thread debugging of core dumps - priting <code>pthread_t</code> of threads and their TLS variables
| |
| * Python scripting improvements not limited to:
| |
| ** GDB values in Python are now callable if the value represents a function address.
| |
| ** New module gdb.types for inferior types.
| |
| ** New module gdb.printing for writing and registering pretty-printers.
| |
| More features are listed [http://sourceware.org/cgi-bin/cvsweb.cgi/~checkout~/src/gdb/NEWS?cvsroot=src upstream] above the line <code>*** Changes in GDB 7.2</code>.
| |
| | |
| Numerous important packages within Fedora are pre-built with [[Features/SystemtapStaticProbes|SystemTap static markers]], and these can now be used as the target for breakpoints in gdb.
