Hello Hardened users, this is just a quick heads up. GCC 4.3.4 will be |
| 20 |
going |
| 21 |
stable on hardened profiles shortly. Unlike Hardened GCC 3.4.6, this |
| 22 |
version |
| 23 |
lacks default SSP building. However, FORTIFY_SOURCE=2 |
| 24 |
and -fno-strict-overflow are now enabled by default. Other Hardenedcompiler |
| 25 |
features (ex. default relro, bind now & pic/pie building) remain enabled - |
| 26 |
no |
| 27 |
change from 3.4.6. |
| 28 |
|
| 29 |
It is regretable this must be done before GCC4 is SSP-by-default enabled. |
| 30 |
However, more and more packages require the newer GCC. The stable GCC on |
| 31 |
Hardened has been GCC 3.4.6 for a long time, but this has become an |
| 32 |
untenable |
| 33 |
situation. GCC4 SSP-by-default works and will be added in a later revision |
| 34 |
- |
| 35 |
some GCC4+SSP bugs in grub and glibc also remain to be fixed. |

Please follow '2. General Upgrade Instructions' in the 'Gentoo GCC Upgrade |
| 38 |
Guide' [1] when upgrading from GCC 3.4.x to GCC 4.3.x. The upgrade should |
| 39 |
be |
| 40 |
relatively smooth, but if you run into upgrade troubles seek help via this |
| 41 |
mailing list, bugs.gentoo.org, or irc.freenode.net, #gentoo-hardened. |
