[Trilinos-Users] Two compilation problems with MultiLevelPreconditioner

[Jonathan Hu]

Hi Ernesto,

     The HAVE_CONFIG_H macro should be defined in the makefile compiling 
your application.

Alternatively, you could use the Makefile.export approach.   To do this, 
add the following line to your application Makefile:

include 
/absolute/path/to/your/Trilinos/build/directory/packages/ml/Makefile.export.ml

This defines two make variables, ML_INCLUDES and ML_LIBS, that 
encapsulate all of the Trilinos headers and libraries that ML depends 
on.  Use these two variables in your application compile and link lines, 
respectively.   Makefile.export.ml also defines the HAVE_CONFIG_H macro.

Regards,
Jonathan
