using the method explained in video lecture 7 did not get rid of the errors.

[Wakil Sarfaraz]

Hello all,
I followed exactly what Prof Bengerth did in video lecture 7 using eclipse to get rid of the errors (step-1.cc/properties/c++ general/path and symbols  and then adding the path from the File System /usr/local/dealii/include/deal.II) it did not help to reduce the number of errors.
However, I must note that the only errors it shows are about the headerfiles of dealii such as

#include <deal.II/grid/tria.h>
#include <deal.II/grid/tria_accessor.h>
#include <deal.II/grid/tria_iterator.h>
#include <deal.II/grid/grid_generator.h>
#include <deal.II/grid/manifold_lib.h>
#include <deal.II/grid/grid_out.h>

the remaining code appears fine (with no error signs).

On emacs however things seems to be fine.

I think the correct path should probably be /usr/local/dealii/include.
Are the deal.II files in this directory? Is this where you installed
deal.II on your system?

This is an issue that is in reality something that we can't fix with
deal.II. It's something that one needs to tell eclipse, and we have
never really found a useful way to tell eclipse the correct combination
of information.

That said, did you watch lecture 8.01?

Sure, but emacs understands nothing of your code to begin with. It
doesn't complain because it doesn't even *try* to understand anything.

Yes I watched both.
So conclusively, do you think I should just stick to using emacs or gedit if I cant get eclipse to work.
Or do you think I lose too much not using eclipse. Apologies if my question is not a standard one.

The thing is that the errors Eclipse shows don't mean that it's not
working at all. It's simply not working as well as it could if it knew
the correct paths. But it still works a heck of a lot better than emacs
or vim. So my recommendation is to investigate again where exactly all
of the deal.II header files went, see if you can fix it, but in any case
continue to work with a reasonable editor such as eclipse.

[Wakil Sarfaraz]

Yes, deal.II directory is in the include.

I think that is what went wrong.

I will try this tomorrow when I am in the office.

Thanks for the prompt reply.

Is there reason you are not using the cmake generator (-G) to create
the eclipse project? I think it should add all paths correctly. At
least it worked for me in the past and also works in my current setup
(using qtcreator).

That was exactly the problem. I added the directory /usr/local/dealii/include without /deal.II and it worked.
Thanks again.
