Red Hat Bugzilla – Bug 22080
RedHat 7 Ships with Gcc 2.96
Last modified: 2007-04-18 12:30:10 EDT
RedHat 7 ships with GCC version 2.96. After experiencing compatability
issues with this software, some research and contacts uncovered the fact
that GCC v2.96 is a beta version of the new and upcoming GCC v3 and was
never intended to be released as a development suite and is not forward or
backward compatable with previous or upcoming versions.
Check out http://gcc.gnu.org/gcc-2.96.html for more information
Why was Redhat 7, touted as a development platform, shipped with a never
meant to be released version of the C compiler?
If you encounter any bugs, please file them here, but the fact that we have
released this compiler is not a bug, it was intentional, see
Richard Henderson's explanation in lwn.net archives for why we decided
to ship this.
If you talk about C++ binary compatibility, then no g++ so far
has been compatible with other major g++ version (2.7.x vs. 2.91
vs 2.95.x etc.).
C should be binary compatible on ia32 (maybe with exceptions of
-mregparm in some cases).
