AW: [Wien] Compilation error

[Gerhard Fecher]

Try the following 
a) switch of -ip in the compiler options, or use the option for interprocedural optimisation within single files only
b) make afminput and aim by hand switching off -ip in the accompanied makefiles

If you like to use your own settings in siteconfig (helps if you set up on several computers), just change the approprite parts in the script.
There is no need to print all the warnings about missing libraries if you have them installed in a different path, just comment those lines.

Anyway, lower Versions of ifort are not less but more buggy.

On Ithanum you should not use the ia32 libs.

More things you may find in my previous post about ifort 9.0 as well as in the compiler handbooks, read carefully the part about optimization.

Ciao Gerhard

Betreff: [Wien] Compilation error
 
Dear All,
         As I have installed Intel(R) Fortran Compiler 9.0 for Linux,
Intel(R) C++ Compiler 9.0 for Linux and Intel(R) Math Kernel
Library 8.0 for Linux, while compiling WIEN2K on both
Itaninum-based and P4-based Linux platforms I come across the
following errors:

Compile time errors (if any) were:
SRC_afminput/compile.msg:ifort: error: problem during multi-file
optimization compilation (code 1)
SRC_afminput/compile.msg:make: *** [afminput] Error 1
SRC_aim/compile.msg:ifort: error: problem during multi-file optimization
compilation (code 1)
SRC_aim/compile.msg:make[1]: *** [aim] Error 1
SRC_aim/compile.msg:make: *** [real] Error 2
and so on.

Since there is one option viz. "J  Linux (Intel ifort 8.1 compiler + mkl
7.0 )" and no option for something like "K  Linux (Intel ifort 9.0
compiler + mkl 8.0 )", I wonder what to do. One remedy may be to lower the
optimization level, or upgrade to a less buggy version of the compiler, or
both. But then how to perform this since I do not have any Intel ifort 8.1
compiler with mkl 7.0 configuration. For example:
"Recommended options for system linuxif8 are:
         Compiler options:        -FR -mp1 -w -prec_div -pc80 -pad -ip
-DINTEL_VML
         Linker Flags:            -L/opt/intel/mkl70/lib/32 -Vaxlib
-static-libcxa -pthread
         Preprocessor flags:      '-DParallel'
         R_LIB (LAPACK+BLAS):     -lmkl_lapack -lmkl_ia32 -lguide

   Current settings:
     O   Compiler options:        -FR -mp1 -w -prec_div -pc80 -pad -ip
-DINTEL_VML
     L   Linker Flags:            -L//opt/intel/mkl/8.0/lib/32 -Vaxlib
-static-libcxa -pthread
     P   Preprocessor flags       '-DParallel'
     R   R_LIB (LAPACK+BLAS):     -lmkl_lapack -lmkl_ia32 -lguide

coming with the following message:
"I could not find the path to the mkl-library (/opt/intel/mkl70/lib/32/)
 Please search whether mkl is installed at all and where
 (You can download mkl from Intel www.intel.com (similar as the ifc compiler)
 Without mkl you should install the ATLAS-blas or you must use the blas_lapw
 library (performance loss)"

Can you please suggest me what changes I need to make in successfully
installing WIEN2K in both Itanium and P4 based systems?

Sincerely,
A. Sen
