Hello, I am following the "Open Source Analog Desi...

Hello, I am following the "Open Source Analog Design Flow" document to build Xyce which depends on Trilinos. I follow the instructions to build a parallel version of Trilinos which builds fine but when I attempt to configure Xyce it complains with:
Copy code
checking for Teuchos_SerialDenseMatrix.hpp... no
configure: error: Unable to compile a test program against Trilinos that includes Teuchos_Serial_DenseMatrix.hpp.  It is possible Trilinos was not properly configured or the environment has changed since Trilinos was installed.  See config.log for more information.
I seem to recall that when I last built Xyce I had to resort to a serial build (the clue is in the name of the missing file) unless that's a false memory. Any ideas on what might be wrong given I follow the recipe precisely?

There's nothing significant about that file; it's just that the "configure" script for Xyce is using it to test that it can find the header files for Teuchos; this is coming from a standard AC_CHECK_HEADER call in configure.ac. Beyond that, you might find some additional helpful information in build/config.log; you can compare to mine which has
Copy code
It was created by Xyce configure R::7.4, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ../configure CXXFLAGS=-O3 ARCHDIR=/home/tim/src/XyceLibs/Parallel CPPFLAGS=-I/usr/include/suitesparse --enable-mpi CXX=mpicxx CC=mpicc F77=mpif77 --enable-stokhos --enable-amesos2
at the top, and then about 80% through the file, I have

In particular, the line that tests for the Teuchos header file is

and indeed, I have the file 
Teuchos_SerialDenseMatrix.hpp
installed in 
/home/tim/src/XyceLibs/Parallel/include
. Either you're missing the include argument, or you're missing the directory. Figuring out which is the first step.

Thanks for answering - this should probably have been posted in the Xyce channel... My bad. I should have looked at config.log in the first instance rather than asking for a hint. I see further problems in the config environment test programs that look like they come from my compiler version/environment.

so compiler/stdlib compliance problem. Thanks again for the brain jog....
