Yes I have read this paper... it deos not give a link to the wrapper it talks about however. Here is a link that has sme older wrappers:

 

http://www.pyrillion.org/index.html?showframe=linuxkernelpatch.html

 

I have not tried them however because I think they are too old to work with a 2.6.2* kernel.

I am a developer with an idea to stat a new kernel source for Gentoo that is specifically for the Intel ICC compiler. Evidentally there is a "wrapper" that is need to be applied to the kernel source first before ICC can correctly complie the Linux kernel. Wher can I get this wrapper? (I have looked all over the web but the only yhing I can find is old documentation)

Looks like your post did not go through...

Hi thaidog, were you asking for a wrapper for 2.6.xx kernel on IA32?  I can share one for 10.x compiler with you.  I didn't test with 11.0 compiler yet.

That would be awsome! I am using the 10 version right now since that is what is available in portage. That is the exact one I am looking for... IA32.

The following is an example of wrapper script.  Please try it with a newer update of icc 10.1.

 

#--------------------------------------------------------

# This is a wrapper script for icc 10.1 on IA-32

#--------------------------------------------------------

ARGS=$@

ICCARGS="-fno-builtin"

 

# For loop to change options of icc

for ARG in $@

do

case $ARG in

-fno-stack-protector  )

     ICCARGS="$ICCARGS -fno-stack-security-check"

     ;;

 

-Wno-pointer-sign | -msoft-float | -ffreestanding )

     ;;

 

* )

     ICCARGS="$ICCARGS $ARG"

     ;;

esac

done

 

icc $ICCARGS

 

exit $?

Bummer.

 

I tried to compile the linux kernel with ICC and got into a horrible mess.  I think it is way too embedded with GCC for it to work but if you managed to get it working, I would be VERY interested.

If you need a hand, please ask.

A hand would be great. I have version 10 not 10.1. Do you know where to get 10.1? I got the wrapper working... but after a few min it errored:


make[1]: *** [arch/x86/vdso/vdso32-int80.so.dbg] Error 1
make: *** [arch/x86/vdso] Error 2

Other people at the gentoo forums are trying it but they are running in to similar issues.

Well I've got version 10.0. Not sure where to find 10.1. I got this error when trying to do it with 10.0:

EDIT: whoops... I did not put it in my path... that's what that error is.
