Hello! |
2 |
|
3 |
I have a clean uClibc environment (not gentoo based), and inspired by |
4 |
hardened-gcc-3.3.2 the gcc specs file was changed to support ET_DYN |
5 |
binaries, the only change I have done is replacing Scrt1.o with "crt1S.o |
6 |
interp.o" (crt1S.o not yet in the uClibc tree, but in portage), due to the |
7 |
fact that Scrt1.o does not exist in uClibc like in glibc-2.3.2. I do not |
8 |
know what the difference is between Scrt1.o from glibc and crt1S.o coming |
9 |
from the hardened-gcc-2.4.6 (the version for uClibc is PaX version, so |
10 |
similar to those in hardened-gcc-2.4.6). |
11 |
Could someone comment on problems regarding this change? |
12 |
|
13 |
I have seen a dependency on binutils-2.14.90.0.7, but this one has some |
14 |
problems with uClibc (does not correctly support canadian cross-compiling, |
15 |
binutils-2.14.90.0.6 yes). Is it really needed, or is |
16 |
binutils-2.14.90.0.6-r7 enough? |
17 |
|
18 |
I have rebuilt about 50 packages (mainly development environment) with |
19 |
these changes, but there is some strange behaviour (it is not related |
20 |
to the fact that everything is -fPIC built, I had this already defined |
21 |
earlier in my CFLAGS for almost all packages) |
22 |
I am also interested in an Scrt1.o version for uClibc, so a changes |
23 |
description between the PaX and the glibc-2.3.2 implementation would be |
24 |
helpful. |
25 |
|
26 |
Why was the default -fomit-frame-pointer option removed? From my |
27 |
experience there are only a few packages, that are incompatible with it |
28 |
(mainly libraries). |

Thanks, Peter |
