  ICC kernel compile wrapper Linux

• thaidog November 14, 2008 12:16 PM PST    Need "wrapper" to compile the Linux kernel with ICC I am a developer with an idea to start a new kernel source for Gentoo that is specifically for the Intel ICC compiler. Evidentally there is a "wrapper" that is needed to be applied to the kernel source first before ICC can correctly complie the Linux kernel. Where can I get this wrapper? (I have looked all over the web but the only yhing I can find is old documentation) zhenhua.zhang November 14, 2008 7:16 PM PST Rate   #1 Re: Need "wrapper" to compile the Linux kernel with ICC You could find 'Linux kernel build white paper with 10.0 compiler' in below URLs. In the bottom of that page, there is another paper discussion the compatibility with GNU Compilers may be also useful for you. http://www.intel.com/support/performancetools/c/linux/sb/cs-007713.htm thaidog November 15, 2008 2:29 PM PST Rate   #2 Reply To #1 Re: Need "wrapper" to compile the Linux kernel with ICC Quoting - zhenhua.zhang You could find 'Linux kernel build white paper with 10.0 compiler' in below URLs.

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 have looked all over the web but the only yhing I can find is old documentation) 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. thaidog November 18, 2008 6:55 AM PST Rate   #6 Reply To #5 Re: Need "wrapper" to compile the Linux kernel with ICC Quoting - Feilong H (Intel) 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. Feilong H.

If you need a hand, please ask. -- Nescire autem quid ante quam natus sis acciderit, id est semper esse puerum.

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: gentoo_x86_32 ~ # cd /usr/src/linux gentoo_x86_32 linux # nano intelwrapper gentoo_x86_32 linux # make HOSTCC=intelwrapper CC=intelwrapper /usr/src/linux-2.6.25-gentoo-r7/scripts/gcc-version.sh: line 25: intelwrapper: command not found /usr/src/linux-2.6.25-gentoo-r7/scripts/gcc-version.sh: line 26: intelwrapper: command not found make: intelwrapper: Command not found CHK     include/linux/version.h CHK     include/linux/utsrelease.h HOSTCC  scripts/basic/fixdep /bin/sh: intelwrapper: command not found make[1]: *** [scripts/basic/fixdep] Error 127 make: *** [scripts_basic] Error 2 gentoo_x86_32 linux # EDIT: whoops... I did not put it in my path... that's what that error is. thaidog November 19, 2008 4:33 PM PST Rate   #10 Reply To #8 Re: Need "wrapper" to compile the Linux kernel with ICC Quoting - nanometrics Quoting - nanometrics   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.
