A premake5 script for building assimp

assimp.lua

-- How to use:
-- 0. Get assimp from https://github.com/assimp/assimp
-- 1. Place this file next to the cloned assimp repository like this:
--
--       assimp.lua
--       assimp/
--
-- 2. Set up configuration headers
--
--     2.1 Create a folder for configuration headers, I usually name it _config_headers/
--
--          _config_headers/assimp/     <- config.h will be included as "assimp/config.h" so the assimp/ part is important
--          assimp.lua
--          assimp
--
--     2.2 Generate config.h and revision.h from assimp/code/config.h.in and assimp/revision.h.in and put them into _config_headers/assimp. (You can also just edit and rename them, that's what I usually end up doing.)
--
--          _config_headers/
--            assimp/
--              config.h
--              revision.h
--          assimp.lua
--          assimp
--
-- 3. Edit the 'files { ... }' and 'defines { ... }' depending on which importers/exporters you need. By default I enabled COLLADA, OBJ, FBX and ASSBIN (assimp binary, good for caching)

I used this script and after some modification the only error i get is that it can't find config.h inside defs.h line 55

Assimp premake

@harshit2608 if you're still interested. Assimp uses autoconf to generate config.h an other include file. Try to find the .h.in, then use premake-autoconf to generate the necessary symbols.

I added some instructions to make this gist easier to use

try using the command cmake . before linking with premake.

I have some linking errors when using this.

Does anyone know why and how to fix it?

Here's the bin of the errors. https://pastebin.pl/view/70a9aacd

@silvertakana Looks to me like either

• zlib isn't compiled correctly or
• The assimp project moved the 'assimp/contrib/unzip/' folder somewhere else

I'm not working on any game engines that use assimp right now (I switched everything to gltf), so I am not keeping this file up to date very much.
If you manage to get it to work, feel free to post your updated version.

First of all, thank you @Cannedfood for making this much easier for me!

I've updated it to work with latest pull assimp, files have just been moved basically and new dependencies added. Only tested it working with FBX and Obj currently, use the above but replace files and includedirs with the following

files {
	-- Dependencies
	'assimp/contrib/unzip/**',
	'assimp/contrib/irrXML/**',
	'assimp/contrib/zlib/*',
	-- Common
	'assimp/code/Common/**',
	'assimp/code/PostProcessing/**',
	'assimp/code/Material/**',
	'assimp/code/CApi/**',
	'assimp/code/Geometry/**',
	-- Importers
	'assimp/code/AssetLib/IQM/**',
	'assimp/code/AssetLib/Assbin/**',

	'assimp/code/AssetLib/Collada/**',
	'assimp/code/AssetLib/Obj/**',
	-- 'assimp/code/AssetLib/Blender/**', 'assimp/contrib/poly2tri/poly2tri/**',
	'assimp/code/AssetLib/FBX/**',
	-- 'assimp/code/glTF2/**',
	-- 'assimp/code/glTF/**',
	'assimp/code/Assbin/**' -- For caching
}

includedirs {
	'_config_headers/',
	'_config_headers/assimp/',
	'assimp/',
	'assimp/contrib/',
	'assimp/contrib/irrXML/',
	'assimp/contrib/unzip/',
	'assimp/contrib/rapidjson/include/',
	'assimp/contrib/pugixml/src/',
	'assimp/contrib/zlib/',
	'assimp/contrib/utf8cpp/source',
	'assimp/code',
	'assimp/include',
}

Thank you very much @Karamu98! I updated the gist accordingly.

Thanks for making this file, it simplifies the work alot.

I did have to make a few changes to work with the latest version of ASSIMP (as of this comment being left) that were pretty minor, it seems like they have added two new file types USD and pbrt so I just added the lines:

'ASSIMP_BUILD_NO_USD_IMPORTER',
'ASSIMP_BUILD_NO_PBRT_IMPORTER'

and

'ASSIMP_BUILD_NO_USD_EXPORTER',
'ASSIMP_BUILD_NO_PBRT_EXPORTER'

In there respective places

I used this file and everything worked except when I tried to turn on the gltf importer. I did eventually get it to work though, I had to change these lines

'assimp/code/glTF/**',
'assimp/code/glTF2/**',

to

'assimp/code/AssetLib/glTF/**',
'assimp/code/AssetLib/glTF2/**',

I also had to set the cpp dialect to c++17 at the top of the file so that inline variables could compile

cppdialect "C++17"

And I also had to add this to the list of defines to fix errors created by glTFAssetWriter.inl

'RAPIDJSON_HAS_STDSTRING=1'

Thank you for creating this script, it would have taken much longer if I had to create it from scratch

Heyo, just wanted to add this here in case anyone trying to build with gcc stumbles upon this

For gcc, just add this define and it should work.

	filter "system:linux"
		defines
		{
			"HAVE_UNISTD_H"
		}  

The final Lua script that worked for me, just in case:

project "assimp"
    kind "StaticLib"
    language "C++"
    cppdialect "C++17"
