Dear Wiki user, You have subscribed to a wiki page or wiki category on "Fedora Project Wiki" for change notification. The following page has been changed by PaulWFrields: http://fedoraproject.org/wiki/Docs/Beats/DevelTools/GCC ------------------------------------------------------------------------------ This release of Fedora has been built with GCC 4.1, which is included with the distribution. === Caveats === + + * Fedora developers have introduced changes in the ELF .hash section that provides symbols for dynamic linking. This new .gnu.hash section, which is produced with the new default `--hash-style=gnu` option for `gcc`, serves the same purpose. It provides, however, an approximately 50% increase in dynamic linking speed. Binaries and libraries produced with the new hashing function are incompatible with older `glibc` and dynamic linker releases. To use the old-style hashing routines, pass the `--hash-style=sysv` option instead. * You need GDB 6.1 or newer to debug binaries, unless they are compiled using the `-fno-var-tracking` compilation option.
