Hi Dirk, I'm not sure if it's the same problem, but we were having issues with icc 8.1 under Red Hat on our Prism system (after upgrading one of our service packs)
Our fix was to download a new version of os_defines.h from Intel. - basically take os_defines from http://www.intel.com/software/products/compilers/downloads/os_defines.h.90 and use this to overwrite the Red Hat version (in our case to /usr/include/c++/3.2.3/ia64-redhat-linux/bits/os_defines.h ) We had slightly different errors to you, but I've just tried your code using our old os_defines, + that fails (with the fix it works).... but then again our problem was whenever we included <iostream>... So this may help, but then again may not! Good luck, + cheers - Adrian On Tue, 2005-07-05 at 13:08 -0500, Dirk Reiners wrote: > Hi everybody, > > I'm having problem with the Intel compiler on Linux that I can't seem to > find a solution for. > > For some reason icc uses the gcc stdlib headers for things like cmath. > These use compiler-specific builtin functions that the intel compilers > doesn't know, so linking fails.
