ogrecave / ogre-next-deps

Packaged ogre-next dependencies' sources with a convenient CMake build system.

OGRE-next DEPENDENCIES SOURCE PACKAGE

This package is provided as a quick route to compile the core dependencies of OGRE-next on most supported platforms. For a list of the included libraries and their versions, see versions.txt

CHECKOUT

This repo contains submodules. Therefore it needs to be cloned using the following command:

git clone --recurse-submodules --shallow-submodules https://github.com/OGRECave/ogre-next-deps

Checkout the Quick Start Scripts to see scripts that automatically clone this repo and build it (and also clone the main OGRE-next repo and build it).

COMPILATION

You need CMake (http://www.cmake.org). In a console, type:

cd /path/to/ogredeps
mkdir build
cd build
cmake ..
make
make install

If you are on a Windows system or prefer graphical interfaces, launch cmake-gui instead. Enter as the source code path the path where you extracted ogredeps (i.e. where this readme resides). Select any directory to build the binaries. Hit 'Configure', choose your compiler set and click Ok. Click 'Generate' twice. CMake will generate a set of project files for your IDE (e.g. Visual Studio or XCode) in the chosen build directory. Open them, compile the target 'BUILD_ALL'. Also build the target 'install'.

Note: Python 3.X is required to build the "shaderc" project. Download link: Python 3.X

USAGE

When compilation was successful and the install target was built, you should find a new directory 'ogredeps' in your build path. This contains the final include and lib files needed. Copy it to your Ogre source directory, rename it to Dependencies (or iOSDependencies or AndroidDependencies for those platforms) then rerun CMake for your Ogre build. It should pick up the dependencies automatically.

Check the manual for more information.

ogre-next-deps's Issues

Relative or absolute CMAKE_INSTALL_XXXDIR variables.

I am not really familiar with cmake. I am very sorry if I am reporting something silly. :-)

I have used ogre-next-deps. I have setup CMAKE_CXX_FLAGS and CMAKE_INSTALL_PREFIX. This is the content of my src/CMakeLists.txt:

# This is the CMakeCache file.
# For build in directory: /home/andre/hd_extra/repositorios/ogre-next-deps/build
# It was generated by CMake: /usr/bin/cmake
# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
# If you do want to change a value, simply edit, save, and exit the editor.
# The syntax for the file is as follows:
# KEY:TYPE=VALUE
# KEY is the name of a variable in the cache.
# TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!.
# VALUE is the current value for the KEY.

Now, I have realized that the generated files pkgconfig/shaderc*.pc give a wrong libdir:

prefix=/home/andre/.local
exec_prefix=${prefix}
libdir=${prefix}//home/andre/.local/lib
includedir=${prefix}/include

Name: shaderc
Description: Tools and libraries for Vulkan shader compilation
Version: 2020.2.1
URL: https://github.com/google/shaderc

Libs: -L${libdir} -lshaderc_shared
Cflags: -I${includedir}

I do not really understand much... but I see two options:

1. @CMAKE_INSTALL_LIBDIR@ should simply be lib, but it is being configured with an absolute path. The file ./build/src/shaderc-prefix/tmp/shaderc-cfgcmd.txt contains -DCMAKE_INSTALL_PREFIX:PATH=/home/andre/.local;-DCMAKE_INSTALL_LIBDIR:PATH=/home/andre/.local/lib/;-DCMAKE_INSTALL_BINDIR:PATH=/home/andre/.local/bin/.
2. In the case of includedir, ${prefix} should not be there either. And "two wrongs made a right", because @CMAKE_INSTALL_INCLUDEDIR@ is relative, not absolute.

The template files are like this:

prefix=@CMAKE_INSTALL_PREFIX@
exec_prefix=${prefix}
libdir=${prefix}/@CMAKE_INSTALL_LIBDIR@
includedir=${prefix}/@CMAKE_INSTALL_INCLUDEDIR@

Name: shaderc
Description: Tools and libraries for Vulkan shader compilation
Version: @CURRENT_VERSION@
URL: https://github.com/google/shaderc

Libs: -L${libdir} @LIBS@
Cflags: -I${includedir}

Maybe none of them (libdir or includedir) should have a ${prefix}/. It is strange, in my opinion, that @CMAKE_INSTALL_INCLUDEDIR@ actually gives a relative include path, instead of an absolute path. But this is also true for SYSCONFDIR, DATAROOTDIR, etc.

I do not really know which one is the correct one. But making all those XXXDIR relative to PREFIX is what makes more sense. In this case, BINDIR and LIBDIR are wrong.

Freeimage doesn't build with latest VS 2019 versions

With version 16.9.3 of VS 2019 (but I suspect with every version greater-equal than 16.8.x as well) Freeimage doesn't build in non-debug modes. The error is related to OpenJPEG library: uclouvain/openjpeg#1333. For what I've understood, OpenJPEG 2.x versions aren't affected by this issue.
An Freeimage upgrade should hopefully fix the problem.

Here you can find a quick and dirty patch to ovverride the issue.

Cannot compile under Android

Hello.

I tried to compile for Android. I used this command line:

# Download ogre-next-deps
git clone --recurse-submodules --shallow-submodules https://github.com/OGRECave/ogre-next-deps
 
# Compile ogre-next-deps
cd ogre-next-deps
mkdir -p build/Android/Release

    -DANDROID_NATIVE_API_LEVEL=24 \
    -DCMAKE_BUILD_TYPE=Release \
    ../../../

After make I have these error:

This warning is for project developers.  Use -Wno-dev to suppress it.

How I understand I should place SPIRV-Headers and glslang to this directory. Could you please where I should take them and what version?

link error building Remotery for macOS with Xcode 14.3 beta

When attempting to build the dependencies using Xcode 14.3 beta, I got an error:

ld: file not found: /Applications/Xcode14.3-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_macosx.a

This doesn't happen with Xcode 14.2. As I understand it, libarclite has something to do with providing runtime compatibility for old versions of macOS. So maybe the problem is that CMakeLists.txt sets CMAKE_OSX_DEPLOYMENT_TARGET to 10.7, while the minimum officially-supported deployment target for Xcode 14.2 and later is 10.13.

Python 3.* required to build shaderc

Hi, just when building these dependencies, python 3.* (I used Pythin 3.10 x64) was beeded to build the "shaderc" project.

1. Would you like this documented?
2. Is "shaderc" necessary for the vulkan renderer?

Compiler errors building FreeImage under Linux

Following the instructions under: https://ogrecave.github.io/ogre-next/api/2.3/_setting_up_ogre_linux.html

Attempting to build dependencies under Linux results in compiler errors about ISO C++17 such as the following:

ogre-next-deps/src/FreeImage/Source/OpenEXR/Imath/ImathVec.h:227:41: error: ISO C++17 does not allow dynamic exception specifications
  227 |     const Vec2 &        normalizeExc () throw (Iex::MathExc);

FreeImage can't compile on Windows because std::binary_function was moved in MSVC 14

Apparently this is a problem on Windows only, MSVC 14 moved std::binary_function into header file "functional"

The solution that worked for me was to add:
#include <functional>
