prelink unmasked

Would this then mean that someone thinks the portage implementation of prelinking is safe... damn that was fast...

Ladies and gentlemen, go ahead and break it.

I hope it is not just an error in the mask

It doesn't like me

Well all the tests passed when I installed, so I took the plunge and issued "prelink -a" (I even added /opt/kde/3.1/bin and lib to prelink.conf). So far so good.

It did complain that several things could not be linked against non-PIC libraries. In particular libz.so.1.1.4 showed up the most by far. Is there any reason zlib would not be built with -fPIC?

check with www.gentoo.org/~cretin/prelink.html for more info on errors..

I'm having a strange bug that makes prelink abort do to an assertion bug ??? but it's not listed so I'm trying to recompile the program.

I have the same problems than Bloody Bastard has.
I have the latest portage, bintutils, gcc, glibc, and even tried without any CFLAGS...

I must be blind but...How did you guyss configure poratage to use prelink?? USE="prelink" ?? I read http://cvs.gentoo.org/~cretin/prelink.html , but all he says is that newer portage versions supports prelink. But how can I put this option (I guess it's an option) on?
Cheers!

emerge prelink

You maybe misunderstood my question. Or perhaps I misunderstand the answer

..... Will portage really prelink all programs I emerge after emerging prelink??
Cheers!

Does anyone know why some of us could not even emerge prelink?

Please, if any of yoo can tell me why 9 of the 14 tests are failed in my system ( with new gcc, glibc, ...) , please please let me know.

Thanks in advance,

Guillermo

I have the same problem that bloody bastard had, 9/14 tests fail, I have new emerges of binutils, gcc, and glibc, in that order just as guide specifies; But all the log files of the failed items have a similar error...

for reloc's it is:
c(number of the item, eg reloc6 is 'c6')
c#:could not find variable copy reloc is against

..whatever that means; And for the shuffle files...

fle(#, eg shuffle1 = fle1)
fle#:could not find variable copy reloc is against

So some variable expressed in the 'reloc' files that is incorrect? Tell me what you think.

invaderzim · Posted: Sat Jan 11, 2003 3:28 pm Post subject: bigger binaries?

no one has mentioned this yet, but arent the binaries much larger after prelinking? I thought it was basically the same as statically linking? anyway, assume a share library needed by [blah] is 1mb and [blah] is 1mb then wouldnt [blah] be 2mb after prelinking?

thanks

I tried to use prelink and it worked great UNTIL...

I have an GeForce2 card and of course have the nvidia drivers. Yes, I did do an opengl-update xfree before I ran prelink. I have ONE application that uses openGL that I like to run. SOO I tried to do an opengl-update nvidia. EVERY time when I did that and then tried to run ANY OpenGL program it would seg fault INCLUDING glxinfo! Once I ran prelink -u, everything worked fine.

I'd LOVE to have prelink running again because I DID see a nice large speed difference. IE konqi startup time normal is .396 seconds. With prelink it was .013!!!!

I too had the same thign 9 of 14 tests failed... today, I got it working though when I switched over to the latest kernel (2.5.56) ... I dunno if that helps or not, but in installing the new kernel, I had to restart my system. I think it was the kernel that changed everything.

I bet, if you ask everyone with the 9 of 14 tests failed, they had the gentoo sources...

Uhm...I have gentoo-sources

seriousmoose · n00b Joined: 07 Nov 2002 Posts: 39

All I know, is when I changed from gentoo-sources to development-sources, prelink worked.

http://www.gentoo.org/doc/en/prelink-howto.xml

could someone help out? Manually doing ./configure
make make check in /var/tmp/.. did not result in anything
more either.

I have the same 9 tests out of 14 failed, and use gentoo sources too (2.4.19-r10)

However I don't feel like using 2.5 just yet. Does prelink work with a vanilla kernel? Or is it safe to switch to a 2.5 kernel, emerge prelink and prelink all the stuff, and reboot on the gentoo kernel?

seriousmoose · n00b Joined: 07 Nov 2002 Posts: 39

I suppose someone should submit this as a bugreport, because it seems consistent with what I said: prelink has problems on gentoo-sources

I just set up prelinking with no problems except some old non-PIC libraries which I fixed and I use gentoo sources, so the problem must be a little more complicated than that.

When I try to prelink I get :

Hello everybody,

prelink gave me the same "9 fails of 14" Bloody Bastard and some others mentioned.
