Perfect. Those MKL libraries did the trick, I may have been using static
versions which could have been one of the issues.. To install, I did the
following steps:
0) Installed the intel compiler and MKL to a directory without spaces in the
name (instead of "Program Files\...). This may have been superstition.
1) The following code was created with all the appropriate namespaces, etc.
in a simple main() :
ublas::matrix<double, ublas::column_major> A(3,3), B(3,1);
lapack::gesv(A,B);
2) Added: #define __ICC 1010 in my headers. I think this may be a small
inconsistentcy with my setup and these headers and will post another bug.
3) Put the ublas bindings in the proper location within the boost header
tree
4) Made sure boost includes were in the include path for Intel C++ in the
Options within Visual Studio. This may be where things are very buggy and
caused me trouble.
5) Added the full paths to "mkl_intel_c_dll.lib", "mkl_core_dll.lib" and
"mkl_sequential_dll.lib" as linker input
6) Compiled and appears to run
The "ipo: error #11035: Fatal error cannot open libmmdd" was an intel linker
error. But I am really starting to think it is a problem in the combination
of Visual Studio 2008 and the Intel build system that comes out of the
Intel/VS2008 project files. Things became inconsistent when I added the mkl
library to the list of library locations in the project settings. I was
planning to move over to a make file based build approach at some point, but
this may make me do it sooner:
On this, do people feel that boost::build is the right approach for library
end user projects with:
* Heavy emphasis on boost ublas and bindings.
* The need to do builds on linux and windows both with Intel C++ (ability
to point at different libs, etc.)
* Manage all of the different optimization tweaks we may need for scicomp
* Sufficiently well documented to figure out how to do things easily?
* Need for precompiled headers
* And I won't be completely lost if I try to use boost::mpi and MPI
bindings to things like MPICH2 in the build.
* Easy enough for lower-tech programmers that I can get them building
sample apps without tweaking a bunch of setup files? (or perhaps if I could
just give them a fixed file)
Thanks for your help, and after I get things running I will try to do my
part with regression testing/setup instructions for older packages.
