 |
|
When I start prelink --all I get tis at the beginning:
| Code: |
prelink: /usr/bin/localedef: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker

prelink: /usr/bin/pcprofiledump: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker
prelink: /usr/bin/rpcgen: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker
prelink: /usr/bin/testload: Could not parse `/usr/bin/testload: error while loading shared libraries: libnormvol.so: cannot open shared object file: No such file or directory'
prelink: /usr/sbin/zdump: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker
prelink: /usr/sbin/iconvconfig: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker
prelink: /usr/sbin/zic: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker
prelink: /usr/sbin/rpcinfo: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker
prelink: /usr/sbin/nscd_nischeck: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker
prelink: /usr/lib/misc/pt_chown: Using /lib/ld-linux-x86-64.so.2, not /lib64/ld-linux-x86-64.so.2 as dynamic linker

So it seems to me he does not use x86_64 libs but x86-libs instead. What effect does this have?

i dont think you need to prelink with amd64. For some reason, it's sort of like implied with the stages. or something. i really dont know why. but yeah something like that

What?
Why exactly I don't have to prelink with amd64? Can anybody confirm that and explain why?

/lib64 is a symlink to /lib, so those are 64bit ld-linux.so's but the fact that at link time the path was specified as /lib instead of /lib64 confuses prelink, you don't need to worry though as the programs listed are so small that prelinking those particular programs is unnecessary. The reason i think they are linked like that is probably because they are part of glibc.

I don't think that prelink is working for me either...

Shouldn't a forced prelink modify just about every binary on the system? The mtime was not touched for anything as far as I can tell.
Also:
root # ls -l /etc/prelink.cache
-rw-r--r-- 1 root root 546138 Jan 27 20:39 /etc/prelink.cache
root # prelink -p
0 objects found in prelink cache `/etc/prelink.cache'
That seems strange. I get 200 pages of library addresses if I do that under my 32-bit chroot.
Can any harm come out of rm'ing prelink.cache and seeing if that is the problem? |

my prelink.cache is | Code: | | -rw-r--r-- 1 root root 76474 9. Mär 14:34 /etc/prelink.cache |
and i noticed a speedup by using it at first time. if you're sure that prelink wont work, use LDFLAGS.

The size of the file really doesn't matter - I was just illustrating that there must be SOMETHING in it at that size, but the prelink -p output shows no records.
I do not dispute that prelink should yield a program-launch performance improvement. |

Ok, prelink -p shows me nothing, too. But if i cat /etc/prelink.cache there're listed all the programs, what's with that? I have no clue why prelink wont work at adm64 but the -p option let me wonder. If prelink doesn't fit at amd64, LDFLAGS will not work, too?

Hm, for one thing, I consider myself pretty lazy so I dropped the prelink thing at the beginning (you do need to babysit your packages if you update them often). I just use "-Wl,-O1" on my LDFLAGS 
Actually, does this make a difference speed wise, I wouldn't know, if it does I can't seem to notice it
Cheers

| I used prelink for a while to speed up load times in kde, but since support for fvisibility stuff went in for 3.4, I've had no need for it as everything loads nearly instantly.... |

What do you mean? I don't get it.

did the job, the newest prelink is maybe broken.
