[SOLVED] Intel Compiler 12.1 + Ubuntu 11.10 (gcc 4.6) + OpenFOAM 2.0.x
 

Greetings to all!

I've been experimenting with Icc (although I have an AMD machine :p) and I'm stuck with Ubuntu 11.10. Those two combined resulted in a dangerous mix where building OpenFOAM 2.0.x out of the box is impossible... unless you know the trick :cool:

Intel's Compiler 12.1 does not support the bleeding edge C++0x features provided with Gcc 4.6, so there are a lot of crazy messages that pop up if one does not add "-U__GXX_EXPERIMENTAL_CXX0X__" to the recipe (source: icpc 12.1.0, Ubuntu 11.10 (oneiric) and g++). Edit these two files and add the expression in bold:

1. "wmake/rules/linux64Icc/c++"
   
   Code:

   ---

   c++FLAGS    = $(GFLAGS) $(c++WARN) $(c++OPT) $(c++DBUG) $(ptFLAGS) $(LIB_HEADER_DIRS) -fPIC -U__GXX_EXPERIMENTAL_CXX0X__

   ---

2. "wmake/rules/linux64Icc/c"
   
   Code:

   ---

   cFLAGS      = $(GFLAGS) $(cWARN) $(cOPT) $(cDBUG) $(LIB_HEADER_DIRS) -fPIC -U__GXX_EXPERIMENTAL_CXX0X__

   ---

And there you go, it's ready to cook :D

Best regards,
Bruno
