Lucas,
This is sort of a silly question, but how feasible is it to compile and link a
dealii project without cmake? I'm pretty new to using C++ so I'm trying to get
a handle on the most basic way to do things.
I wrote a little file `dealii_function_test.cpp` to test out the Function,
Point, Vector, and Full_Matrix classes, as well as a simple accompanying
Makefile. The former just creates objects of those types and then prints the
contents. The latter searches through `src` and `include` directories in my
own project directory. I can post the text to these files if it would be helpful.
When I try to compile I get a lot of "undefined reference to" errors pointing
towards dealii functions. I can post a file with the error output if that
would be helpful. Do I just need to include a reference to the relevant dealii
object files? And if so, what do those look like/where might they be? In my
`/usr/local/lib` directory I have some dealii libraries (named some
combination of libdeal_II, so, g, and 9.2.0). Do I need to explicitly
reference those? And if so, why does make not know to look there?
For any non-trivial project, trying to set things up "by hand" is going to
result in disappointment and frustration. You will have to know not only where
header files are located, but also the name and location of the deal.II
library you want to link with, the flags used to drive the compiler, possibly
preprocessor #defines, and what other libraries deal.II depends on. All of
this is information that cmake exports and that your project would
automatically import if you used cmake.
This is wheel already invented. Don't waste your time trying to re-invent it :-)
Cheers
W.
