<br>
Sorry, I had a typo: I was still editing the .f90 program file
instead of the .F90 file.<br>
<br>
However, now I am having troubles forming the matrice I would
like to diagonalize.<br>
Presently the size is not yet huge and it could be held in a
previously computed matrix of dimension N*N.<br>
<br>
I am using the following to build the matrix and the compiling
from the example 1 and slightly modified:<br>

Once more, the program execute without troubles for all the examples
in the package.<br>

send us the code that breaks. Also copy/paste the *complete* output from 'make' when
you attempt to compile this code.

Try .F files instead of .F90 some Fortran compilers handle preprocessing in different ways for .F and .F90
Please also send configure.log and make.log so we know what compilers etc you are using.

Note that we are using C pre processing directives,

Thank you for the quick reply.
It partly solved the problem; the PETSC and SLEPC files are now included in the compilation.
However the Warning are now error messages!
***

These should not be capitalized.

And the corresponding code lines are:
***
#INCLUDE <finclude/slepcepsdef.h>
USE slepceps
!

!

I am having trouble compiling a code with some dependencies that shall call

The compilation however goes perfectly for the various tutorials and tests in

<pre wrap="">Its best to rename your sourcefiles .F/.F90 [and not .f/.f90
