Adding Units to FPC from GitHub
lazarus / 62-General

----------------------------------------------------------------------
Mark92630 · 2015-03-30 16:59

Mac OS X 10.10 (Yosemite), with fpc (2.6.4), fpcsrc, and Lazarus
(1.2.6) installed.

I have not been using Lazarus, because the learning curve with
Lightweight-IDE looks a LOT less steep.

Anyway, I've been writing some elementary programs in fpc (using
Lightweight-IDE), and they mostly work just fine. Now, I want to add
some code from GitHub to my existing Pascal environment, namely
"generics.collections" from "dathox", and I have no idea how to do it.
There are no installation instructions for this on GitHub.

Can anyone help?

TIA,

Mark

You'll need to install trunk version of FPC for that.

Then get the files on your harddrive.
make sure fpc has the search path set up to
(-Fu%thepathwherefilesare%)

the added generics.collections to your uses section
Code: [Select]uses ... generics.collections

So, now I have multiple questions, but I will take them one at a time.

When I start fpc from the command line, why am I getting ppc386 and
not ppcx64? Here are the first three lines back from typing "fpc"
(without the quotes) at the command prompt, and hitting [enter].

Free Pascal Compiler version 2.6.4 [2014/02/26] for i386
Copyright (c) 1993-2014 by Florian Klaempfl and others
/usr/local/bin/ppc386 [options] <inputfile> [options]

Thanks,

Mark

that's because i386 is a default target (selected by "fpc") for OSX.

passing -Px86_64 to fpc will make it select ppcx64.

Thanks. Next question, when I look at compiling units as described in
the documentation:

http://www.freepascal.org/docs-html/user/userse11.html#x27-340003.3

it refers to .pp files. But "generics.collections" has a /src folder
with a bunch of .pas files and a sub-folder /src/inc, with a couple of
.inc files. I tried to feed a .pas file to fpc, but it complained that
the file contained an "Illegal unit name: Generics".

Is this where I need a Version 3 compiler?

Yes, this is the where you need Version 3 compiler.
