 Posted: Tue Jul 02, 2002 12:05 pm Post subject: glibc compile flags |
 |
|
Just bootstrapped with
-march=i686 -O3 -malign-double -falign-functions=4 -fschedule-insns2 -pipe
without a hitch (using the stage-1.3b-r1 tarball). The same flags however broke python in stage 2 (some kind of access violation with pod/pod2html, if anybody knows which flag causes this please let me know).
-mwide-multiply gives me the "value too large for designated data type" error compiling glibc.
Is there a safe way to remerge glibc after I have a working stage3 system, so I can try -march=athlon -mmmx -m3dnow -funroll-loops as well? |

last weekend i installed a new gentoo system from the 1.3b tarball. I used
-march=i686 -mcpu=i686 -fomit-frame-pointer -O3 -pipe
everything compiled fine, i have working gentoo 1.3b including kde 3.0.1-cvsblabla now.

Right, that's because -fomit-frame-pointer is stripped from the CFLAGS before compiling glibc.

Hi,
Anyone here using apache with phpsupport here? it compiles fine for me with gentoo 1.3b but when starting apache it cannot load the phpmod  (sorry, i cant write the errormessage because i have to use gcc2 because i want apache with php).
my second problem was that kde compiles fine, but noatun cant play anything. you can add things to the playlist but nothing plays . Normal kdesounds work without probs.
cya

Hi!
My installation fails while "emerge system" at the Python package.
If I emerge the newest Python without "-r*" (IITC 2.2.1), it installs
fine, but emerge is fscked up afterwards
Any way to fix Python now?
If helpfull, here are my flags for a 800mhz athlon:
| Code: |
-mcpu=athlon -march=athlon -O3 -pipe -fomit-frame-pointer -malign-double -mmmx -m3dnow -mno-sse -mno-sse2

It just MIGHT be the -malign-double. I JUST now ran into the same issue, and I built the system fine with the flags I had before:
-march=pentium3 -mcpu=pentium3 -mfpmath=sse -mmmx -msse -O3 -pipe
When I added -malign-double... I bootstrap... that works.... stage 2... Python... !KABOOM! So I will remove the -malign-dobule and retry (which I am sure will work again, as it did before)

When emerging net-mail/procmail-3.22-r6, the following line built properly on my dual athlon-mp system:
| Code: | | CFLAGS="-march=athlon-mp -O2 -pipe -fomit-frame-pointer -falign-jumps=5 -falign-loops=5 -falign-functions=64 -funroll-loops -mfpmath=sse" emerge procmail |
The only way in which this deviates from my normal build configuration is that it omits -finline-functions. Looks like that's one to filter.
For verbosity, here is my "emerge info" output (these are my default settings, and WILL break procmail at strstr() benchmarking):
