Compiling Branch 2.1 Windows 8.1: Boost, SDL2 not found

[criatura]

Hi,

I want to compile Ogre with the samples2 and thread support (it is appears as None), but cmake is not finding boost and "sdl".

I'm a very sad person, using Windows 8.1 64, Visual Studio Community 2015 and CMake to compile Ogre 2.1 (from date November 3). I have boost 1.59 installed (I downloaded the source and compile it), I defined environment variables BOOST_ROOT,BOOST_INCLUDEDIR,BOOST_LIBRARYDIR. However boost is not found by CMake. I Also tried installing boost using the installer (boost_1_59_0-msvc-14.0-64.exe). Also tried adding 1.59 to the line set(Boost_ADDITIONAL_VERSIONS ..) in Dependencies.cmake. Boost is always mark as not found, injuring my soul and changing the meaning of my life.

I followed this guide:

http://michaelcummings.net/mathoms/gett ... indows-8-1 (Thanks for the creator!)

I just let the default options and mark OGRE_BUILD_SAMPLES2.

I downloaded libsdl2 (SDL2-2.0.3.zip), it is checked as found by CMake, but then it gives an error from the CMakeLists of Samples2, I checked the error if and it is related to OIS:

if (OGRE_BUILD_SAMPLES2 AND NOT OIS_FOUND)
message(STATUS "Could not find dependency: SDL2")
message(STATUS "Skipping samples build")
set(OGRE_BUILD_SAMPLES2 0)
else()

You need OIS for Samples2?

Anyways I downloaded and compiled OIS from here (http://ufpr.dl.sourceforge.net/project/ ... s-v1-3.zip) and let it in the Dependencies folder, it is not found by CMake.

Also, I tried deleting that checking and then got a hundreds of compilation errors!

I'm getting the following output from cmake:

Any help is appreciated. I offer remote Chakras Alignment to any human being that helps me to get out of this compilation nightmare. The alignment will be made automatically if I got the problem solved

The best way to satisfy all of Ogre's dependencies at once is the ogredeps project (SDL2 and OIS are in there as well as others):
https://bitbucket.org/cabalistic/ogredeps

If you drop that repo into the top level of your Ogre source in a folder named "Dependencies" then Ogre's CMake script should include it (I don't do this but I see it in the CMake scripts and I've heard tell of it). Or you can build ogredeps separately and its install target will create a folder structure you can drop into Ogre before building.

About the samples2 requiring OIS I noticed that line because I tore all references to OIS out of my fork ... I'm not sure it's correct either, but I am too lazy to confirm. I do all my work from 1.10 right now too, so I'm not in a great place to comment on anything 2.0 or 2.1

About boost I have been through some pain back when I used to depend on it, so I feel you. It's a rough journey but definitely turn on Boost_DEBUG and dig through its output to understand what exactly it is looking for and thus why exactly it fails. It doesn't hurt to open up FindBoost.cmake that installs along with CMake but much is externally documented about its functionality also: https://cmake.org/cmake/help/v3.0/module/FindBoost.html

Just made it sticky because it gets asked a lot

When I tried a couple of weeks ago, sdl2 didn't work with the ogredeps in Dependencies directory method. I had to build it separately. I don't know enough cmake to track down the problem though (I prefer premake).

Thanks for your patience and time. I got Ogre working with samples2. Using this repo: https://bitbucket.org/cabalistic/ogredeps was the key.

Anyways, I have a doubt. Ogre doesn't need boost or some other library for the threads that it uses internally?

I will post my experience, it is just a compilation of information that is in the tutorials, forum, etc.

There are two types of threading: The old one, and the new one (introduced in Ogre 2.0)

The old one is optional and needs Boost/Poco/TBB. It's crap to be honest. isn't really useful, doesn't improve performance in almost all cases.
The new one cannot be turned off and doesn't require any third party library.

I'm really glad you mentioned that. I thought I needed boost to enable the new threading, but if not then I won't even bother with it.

Maybe it's time to drop that dependencies?

Nothing would make me happier. But I'm not sure if somebody has actual use for them.

I'm using it (Boost) to prepare resources in background through the ResourceBackgroundQueue class.

Is Boost required for this class or is this using the new threading system, too?

Yep, it uses the old threading system.
