How do I do something a little more interesting like initialize a vector or matrix and do some linear algebra with it? Thanks so much for your help. This forum is awesome! TJB

I'm not familiar with this library, you'll have to take a look
through the documentation:
https://github.com/kyllingstad/scid/wiki
I see there is a matrix module
http://www.kyllingen.net/code/scid/doc/scid_matrix.html
import scid.matrix;
void main() {
auto m = matrix(5, 10);
}
Then go modify its values, and use some linalg functions with it:

The command Jesse posted is missing a -L-lscid and you'll probably
also need -L-L/usr/local/lib
So the complete command should be:
dmd -I/usr/local/src -L-L/usr/local/lib -L-lscid main.d
Here's a short explanation of those flags:
the -L prefix tells dmd to ignore this argument and pass it to the
linker(ld). So in our case, -lscid and -L/usr/local/lib are passed
to the linker. -l means link in a library, here 'scid'. The linker
appends the 'lib' prefix and 'a' suffix for you, so it searches for a
'libscid.a' file. -L (passed to the linker!) adds a directory to the
library search path. These are the directories which are searched by the
linker when looking for the 'libscid.a' file.

There are many ways to go about using modules, I will go over
installing a module for Linux. Usually the simplest way to get
started is to pass all files to the compiler (you use an import
statement to import the modules).
Build SciD as a library.
$ dmd -lib -oflibscid.a all.d files.d for.d SciD.d
Copy lib to /usr/local/lib
Copy sciD source files in the same direcectory structure
(propably starting with scid/) to /usr/local/src
Installed.
Create a main.d file somewhere:
$ cat main.d
import scid.something;
void main() {}
$ dmd -I/usr/local/src main.d
Windows would be something different, however optlink doesn't
have a standard set of locations to look for library files. you
can also pass the library to dmd
$ dmd -I/usr/local/src main.d libscid.a -- If it is in the same
directory as main.d

Okay. I tried this. I think I am close. I followed the
instructions that you gave (thanks btw)!
But, I get this error message:
$ dmd -I/usr/local/src main.d
main.d(1): Error: module scid is in file 'scid.d' which cannot be
read
import path[0] = /usr/local/src
import path[1] = /Users/name/dmd2/src/phobos
import path[2] = /Users/name/dmd2/src/druntime/import
Thoughts?
Thanks!

Thanks! TJB You don't import scid; as that is just a package, you need a module such as: import scid.matrix; but it will truely depend on which modules you need for the code you are writing.
