[Trilinos-Users] building Trilinos with Intel 7.0

[Willenbring, James M]

(Trilinos-Users note I forgot to CC the list into my reply - you might wish
to wait for another response before tackling the problem.  My response
centered around a stray ", and some alternative ways to pass options.)

Tony,
By the way, I know of no one who as compiled Trilinos using Intel compilers.
We have talked about it, and will try to get to it.  If you get a script
that works, please send it our way.

Thanks.

Jim

Subject: [Trilinos-Users] building Trilinos with Intel 7.0

I have a quick question.  Has anyone been able to build Trilinos with
Intel's compilers ( icc and ifc ) version 7.0.  I keep getting an error
that looks like this:

checking for Fortran 77 libraries...
-L/opt/tritium/intel/compiler70/ia32/lib -L/opt/tritium/blas.intel/lib
-L/opt/tritium/lapack.intel/lib -L/opt/tritium/mpich.intel/lib -lm
-lblas
-llapack -lmpich" -L\ -lmpich -L/usr/lib -lintrins -lIEPCF90 -lF90 -limf
-lirc -lcxa -lunwind
checking for dummy main to link with Fortran 77 libraries... unknown
configure: error: linking to Fortran libraries from C fails
configure: error: /bin/sh '../../../Trilinos/packages/epetra/configure'
failed for packages/epetra

Inside of packages/epetra/config.log is:

configure:5888: icc -o conftest -O1 -tpp6 -xiM -mp -prec_div -pc64
-I/opt/tritium/mpich.intel/include
-L/opt/tritium/intel/compiler70/ia32/lib -L/opt/tritium/blas.intel/lib

-L/usr/lib -lintrins -lIEPCF90 -lF90 -limf -lirc -lcxa -lunwind >&5
ld: cannot find -lmpich"

I am building Trilinos using a bourne shell script:

-*-*-*-*-*-*-
#!/bin/sh

# Make sure that the build environment is set up properly
. /etc/profile.d/iccvars.sh
. /etc/profile.d/ifcvars.sh

export CC="icc"
export CXX="icc"
export F77="ifc"
export CPPFLAGS="-I/opt/tritium/mpich.intel/include"
export CFLAGS="-O1 -tpp6 -xiM -mp -prec_div -pc64"
export CXXFLAGS="-O1 -tpp6 -xiM -mp -prec_div -pc64"
export FFLAGS="-O1 -tpp6 -xiM -mp -prec_div -pc64 -132"
export LDFLAGS="-L/opt/tritium/intel/compiler70/ia32/lib
-L/opt/tritium/blas.intel/lib -L/opt/tritium/lapack.intel/lib
-L/opt/tritium/mpich.intel/lib"
export LIBS="-lm -lblas -llapack -lmpich"

../Trilinos/configure --prefix=/opt/tritium/Trilinos-3.0.intel
--with-mpi-cc=icc --with-mpi-cxx=icc --with-mpi-f77=ifc
--enable-referencey12m && make && make install
-*-*-*-*-*-*-

I think that configure is choking because it cannot find libmpich.a.
This is due to the -L\ that crept into the ac_cv_flibs variable.  Has
anyone been able to build Trilinos with the Intel compilers?  If so how
did you build it.  I have gotten Trilinos to build using the GNU C and
C++
compilers combined with the Lahey Fortran 95 compiler and a build script
very similar to that above.  I think that the problem is an interaction
between the configure script and Intel's compilers.  Any comments on
what
may be wrong would be very much appreciated.
