 |
|
Hi all,
I am using Gentoo (hardened) as guest on XenServer. It is working very good, I am very happy with that. ;-)
A few days ago was released new GCC (4.7.3-r1) and I have encountered some issue:
| Code: | checking for suffix of object files... configure: error: in `/var/tmp/portage/sys-devel/gcc-4.7.3-r1/work/build/x86_64-pc-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details. |
As far as I know the problem is associated with -march=native. So far this flags work well, until now...
gcc -march=native -E -v - </dev/null 2>&1 | sed -n 's/.* -v - //p' ::
| Code: | | -march=corei7 -mcx16 -msahf -mmovbe -maes -mpclmul -mpopcnt -mabm -mno-lwp -mfma -mno-fma4 -mno-xop -mno-bmi -mno-tbm -mno-avx -msse4.2 -msse4.1 --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=8192 -mtune=generic -fno-strict-overflow -fPIE -fstack-protector-all |
grep -m1 -A3 "vendor_id" /proc/cpuinfo
| Code: | vendor_id : GenuineIntel
cpu family : 6
model : 60
model name : Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz |
Gentoo wiki says that I should use this flags for my CPU:
| Code: | CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=core-avx2 -O2 -pipe"
CXXFLAGS="${CFLAGS}" |
... but it does not work.
The only way to "pass compilation" is remove -march. But the question is: how to affected on performance? And second question: why this problem occur? On other VM (but not hardened) everything is fine.
