Failure reading file withe the win32 binaries

Hi, I am trying to use the win32 binaries to read an ifc file with the following line:
C:\assimp2json-master\bin\Debug\assimp2json --log --verbose rac_basic_sample_project.ifc test.json
and it outputs:
failure to read file rac_basic_sample_project.ifc
I have successfully converted this file using the online converter so it seems like there is an issue with the win32 binaries... is it possible to have a look and update the binaries to their latest version please?
I have been trying to build it myself with CMake and Visual Studio 2013 and it does not find some libraries so I am stuck...
Any help would be greatly appreciated!!

"bad escaped character" error in json

e g this fbx file converts to this json file which fails to parse in firefox with following error:

SyntaxError: JSON.parse: bad escaped character at line 9141 column 53 of the JSON data

Fails with latest assimp

It seems the codebase relies on some deprecated code from the core lib:

https://github.com/acgessler/assimp2json/blob/master/assimp2json/json_exporter.cpp#L23

wants to pull in https://github.com/assimp/assimp/blob/93bb63fdb40d9682e60ca97b0eda4951a552c742/code/BoostWorkaround/boost/scoped_ptr.hpp

But this hasn't existed in ~3 years?

Converted models are in black sometimes

HI,

Really thanks for the great work,

if we convert some models in the OBJMTL or collada models, some of the time they are looking black, no textures are applying, so the models are looking very bad, what is the reason behind on it??

compile error with gtest

Sorry if I'm missing something obvious...
but I'm doing the usual "mkdir build && cd build && cmake ../ && make"
and getting a gtest error. Perhaps you're missing a CMakeLists or I'm missing a library or something?

Full output of make:

Design a more compact version of the format that keeps vertex data in separate blobs

Allow configuration of flags

I have some models that require AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE with a value of less than 70. Any chance to supply a config file with settings as a command line param?

My simplest test case is to create a 'cone' in blender and save. The bottom surface tris have 'funky' normals around the edge due to shared vertices with the sides.

Make dropping lines optional?

Hi,

Is there any specific reason for dropping lines (https://github.com/acgessler/assimp2json/blob/master/assimp2json/main.cpp#L74) or would it be possible to add support for this type in the exporter also?

Cheers

/usr/bin/ld: cannot open output file assimp2json: Is a directory

Building assimp works fine after a bit of tinkering, but the Readme.md is pretty unclear about building assimp2json.
When building from https://github.com/assimp/assimp2json, the error "/usr/bin/ld: cannot open output file assimp2json: Is a directory" is produced.
When searching the web for this problem, I found that with other software it was fine to delete the conflicting directory, but that is not the case here, the contents are required.
Also renaming the dir on the filesystem and the references to the dir in the CMakeLists.txt, did not work, as it resulted in the output file name being changed to that of the new dir name.
In the make manual I can not find an option to change the output path. And after searching the web some more I feel stuck.

Less sussinct output around the error: "

".

Commands I use to build: "
git clone https://github.com/assimp/assimp2json
cd assimp2json
git submodule init
git submodule update
cmake CMakeLists.txt
make
".

Also tried "cmake CMakeLists.txt -G 'Unix Makefiles'" as stated in https://github.com/assimp/assimp/blob/master/INSTALL, to no avail.

As https://github.com/assimp/assimp2json is forked from https://github.com/acgessler/assimp2json which has more recent commits (2013 vs. 2015), I also tried building that with the same commands.
And changed line 34 of assimp/cmake-modules/AddGTest.cmake from "GIT_REPOSITORY https://chromium.googlesource.com/external/googletest" to "GIT_REPOSITORY https://github.com/google/googletest/".

This makes a bit of progress, but not enough: "

I imagine other were able to build assimp2json in a linux environment and might share how to?
Or that others can confirm that this is not working? Or perhaps work on a solution together.
Help would be appreciated.

Compile with xcode error

xcode cant find these two:

 #include <assimp.hpp>
 #include <export.hpp>

Any suggestion whats wrong or how to solve this?

What --flags are an option?

The README specifies flags can be passed on to the command line however I do not see what those flags are. Is this documented anywhere?

convert fbx to json not working

while convert the model from fbx to json, it is not working, i can't see any output or error, also i want to know that the converter is work with the animated models?

json2assimp

I'm writing a json2assimp importer, and I was wondering if you cared to collaborate. I will be using your format, or a newly defined format X3D/JSON that I've been writing loaders/converters for in JavaScript. This will allow us to roundtrip the JSON back to assimp for verification. Thanks for any input/collaboration you provide.

Win32 binaries

Sorry for stupid question but why assimp2json.exe works on one computer in Windows 8.1 but doesn't work on other in Windows XP? What are the system requirements?
