i rember seeing a utility which alows you to compare the registers used in a compiled binarey ie 24 lines use mmx and the like anyone seen heard of it, also just noticed icc8 is now in ~x86 which is handy

God DAMNIT! ICC'd bzip2, db, and readline break python compilation! Oh well, this is why I have a 2 ghz cpu I guess...

I'm drooling! Maybe even build GCC under ICC! Super fast emerges!
Just re-reading this thread and saw this. Why in the name of jebus would you want to compile one compiler with a different one?

And a listing of apps would be sweet.

Rebuilding gcc with icc wouldn't help anyway, because all the build would do is build xgcc using icc (if it's possible at all.) Eventually the gcc build would build a compiler to build itself.

well, I only get ICC 7:

what should I do to get icc 8 from the portage tree?

I keep getting it complaining about being unable to create executables. I've tried with CFLAGS="", I don't have any strange portage features enabled, and I use the script which someone posted quite early in the thread (page 1 or 2) that sets AR, LD, CC, CXX, FC, FF, FORTRAN, and all the rest.

Helpies?

galay2 · Post by **galay2** » Mon Mar 22, 2004 9:42 pm

why cant the ebuilds for all those "known to work" at the front page be changed to use the icc use flag? This way everyone can just add the use flag and emerge -uD world with a functional system? Moreover, if it's known to work, shouldnt it be default as part of the install doc? I mean faster apps is always better right?

I have a bit of a prob with icc. i'v gotten icc to install and works nicely and all. but the prob that i'v having is that its entry in /etc/ld.so.conf always seems to get removed with every new emerge. is there a way that i can get icc's entry in it to stay?

chocolate · Post by **chocolate** » Wed Mar 24, 2004 1:22 pm

I read the list of apps that can be compiled and successfully built using icc.

What about mpich and fftw? I am trying to do it (following the intructions given in this thread) but the emerge aborts...

thank you very much

Ahh, it was my CFLAGS it puked on -march=pentium3 so I stripped it down to -O3 and it worked ok.

ICC still has a bit to go before it fully replaced GCC. Looks like the intel version of -march is -ax(char) so for a pentium 3 it is -axB

Note to self. If you keep /opt on a separate partition and have compiled something with ICC that may be used during boot, (i.e. Bash, coreutils) your system won't boot because it needs the libs that ICC provides. You'll get a bunch of failed deps and then it will just freeze.

stonent · Post by **stonent** » Tue Apr 20, 2004 6:49 am

Some things I compiled:
Xine, XMMS, Xfwm4, xfcalcendar, eterm, bash, coreutils.

I wonder if gcc will compile? Hmmm

I doubt icc would compile gcc, but even if it did it would be pointless to do, since gcc would ultimately be used to rebuild itself (it uses a 3-stage compile process).

stonent · Post by **stonent** » Tue Apr 20, 2004 5:02 pm

Well on many commercial Unixes you have to compile GCC until GCC is distributed for it.

Now that I have ICC 8, I've noticed when I try to do a emerge -U --deep -p world, it wants to install ICC 7.1

as N

Code: Select all

Aurora root # emerge -U -p --deep world
>>> --upgradeonly implies --update... adding --update to options.

These are the packages that I would merge, in order:

Calculating world dependencies ...done!

[ebuild     U ] media-libs/libsdl-1.2.7 [1.2.6-r3]

[ebuild   R   ] dev-lang/icc-8.0.055

Something is screwy. I just re-emerged ICC8 just to be sure, but it didn't help.

Did you edit /etc/ld.so.conf directly? It is generated from LDPATH entries in the files in /etc/env.d. The icc8 ebuild should include /etc/env.d/05icc-ifc with the corrent entry.

I encountered a subtle problem with bzip2 when compiled with icc. It was breaking the use of SVG themes in gnome 2.7.1. Recompiling bzip2 with gcc fixed the problem. Just a heads up that the package might not work completely with ICC (even compiled with -cxxlibs-gcc).

I've searched around a bit but haven't found out how to use icc with portage. I don't think `emerge icc` is enough...

I have never used it but I think you also need the icc USE flag - but not sure if even that's enough..

Hello!

I have been trying to update (intel premium support) the masked IFC that "appears" in portage, that is: l_fc_p_8.0.034. The update lives in an RPM package. This gives me some segmentation fault related error... In http://forums.gentoo.org/viewtopic.php?t=223535 I have expossed the situation.

Can anyone help me?

Thanks!

Hi, is there any news about icc in portage implementation?

I've found a new ebuild for the 8.1.024 version: http://bugs.gentoo.org/show_bug.cgi?id=68117

The author is talking about how he compiled a series 2.4 kernel using a series of patches. Good practice of my Japanese

.

How exactly would I add the relevant CFLAGS, CHOST, and CXXFLAGS to my /etc/make.conf file?

Also, are any exported variables such as compiler name, options, etc overwritten by emerge when I run it? So if I use a script, like Cheesefoam suggested, would it follow through or does it require more hacking?

Well, With all of the optimizations that icc could add, why don't I see alot of documentation on it on the web. Often when I find anything it is scattered and obscure. Like even this forum for example.
I propose an ICC compilation wiki as the current gentoo ICC wiki site is inadequete. We could have different sections.
The kernel would get a good section (have you seen the stuff at www.pyrillion.org about kernel compilation. kicc helps out a little), then we could have a section on other programs, seperated by ones that work (without problems), one that work (with a little TLC and patching), and ones that are still hurdels for the gifted to help us overcome (and maybe even send fixes to the authors). While this would be mostly focused towards gentoo users (I don't know many more distros where people enjoy compiling thier own source as much as gentoo....well, excluding LFS or Lunar Linux), it would be a good step forward for the entire linux community.
What do you all say? Is there anyone willing to help me with such an endevor?
~Joshua
P.S. I am working on a 2.6.6 kernel with icc, so far, almost green, but I think i have a resource problem (or something else wrong).

ICC / IFC 8.0 is out!
