Sei Lisa 0040fbea18 Update build system

- build-aux.py:
  - Remove commented line
  - Expose '-' for stdin/stdout in setvars (it was implemented but not exposed)

- Makefile:
  - Default to gcpp as preprocessor instead of mcpp.

- BUILD_GUIDE.md:
  - Now both Python 2 and 3 can be used, so remove the version requirement.
  - mcpp is not available in precompiled form for newer Mac processors, so indicate cpp instead.
  - Explain how to modify Makefile for mcpp.
  - Other minor changes

Creating a release version

Needed tools

To create a release version like the ones available for download, you need to have the following tools:

For Linux

zip. It comes in most distributions, e.g. for Debian or Ubuntu use sudo apt-get install zip; if it isn't available in yours, try this link: http://www.info-zip.org/Zip.html#Downloads
Python. It comes in most distributions, e.g. for Debian or Ubuntu use sudo apt-get install python; if it isn't available in yours, try this link: https://www.python.org/downloads/.
make. It comes in most distributions, e.g. for Debian or Ubuntu use sudo apt-get install make; if it isn't available in yours, try this link: https://www.gnu.org/software/make/#download.
GNU cpp. It comes in most distributions, e.g. for Debian or Ubuntu use sudo apt-get install cpp. If it isn't available in yours, or you have trouble installing it, you can instead use mcpp, which is much more lightweight and is included in most distributions. It is also available at this link: http://mcpp.sourceforge.net/download.html. gcpp comes preconfigured by default in Makefile. For mcpp, you need to set PREPROC_KIND=mcpp and PREPROC_PATH=mcpp in the Makefile.
LSL-PyOptimizer. Currently the latest master branch is used to create the releases, which you can download by clicking on the Code button near the top right of the linked page.

For Mac OS/X

zip (comes preinstalled)
Python (comes preinstalled)
make - It comes as part of the command line develompent tools (Xcode) which you can install for free. Open a terminal and type make; if you don't have it installed, it will prompt you to install it. Xcode can also be installed manually from https://developer.apple.com/.
cpp - Should come as part of the command line development tools where make is.
LSL-PyOptimizer. Currently the latest master branch is used to create the releases, which you can download by clicking on the Code button near the top right of the linked page.

For Windows (x86)

zip
Python
make
mcpp. Makefile comes preconfigured for gcpp, therefore you need to edit it by setting PREPROC_KIND=mcpp and PREPROC_PATH=\full\path\to\mcpp.
LSL-PyOptimizer. Currently the latest master branch is used to create the releases, which you can download by clicking on the Code button near the top right of the linked page.

For processors other than x86, you need to find the above utilities for your processor.

Creating the release

Once you have the required tools, edit the Makefile in the AVsitter2 folder to suit your needs, then using a terminal (also called command interpreter, shell, console... depending on the operating system) change to that folder using cd <path-to-folder> and type make. That should generate a file called AVsitter2.zip with the packaged version for SL, and another file called AVsitter2-oss.zip with the packaged version for OpenSim.

If you only want the Second Life optimized scripts without zipping them, use make optimized. The optimized files will have an .lslo extension, and they are ready to be copied and pasted each into a Second Life script.

If you only want the OpenSim scripts without zipping them, use make opensim. The OpenSim files will have an .oss extension.

If you only want the SL zip, use make AVsitter2.zip; if you only want the OS zip, use make AVsitter2-oss.zip.

If you want to remove the optimized scripts and the zip files, use make clean (you can regenerate them at any time by typing make).
