I can finally announce that the Stellar Qt/C++ SDK port is done. I renamed it from StellarQore to StellarQtSDK to make sure that there is no confusion with Stellar Core. I also moved it to github It has all the functionality and tests as the official Java SDK and it is proven to work in the wallet I presented for the last Challenge. https://github.com/bnogalm/StellarQtSDK I finally licenced it as MPL licence. It is almost the MIT licence but improvements to the source code must be published. So feel free to build anything with it. On the other hand, Qt is licenced as GPL/LGPL, a company is behind it but also the KDE community is backing it. For people wondering why I chose Qt: first because Qt is my preferred framework to work with. I love the flexibility and the power it has. It is really multiplatform, it allows you to build energy optimized applications with attractive interfaces. This SDK opens the door to Stellar to C++ developers who don´t like to run code inside a browser engine. On the other hand, Qt is aiming nowdays to the Internet of Things. With the next version Qt 5.10, two new modules will be included (MQTT and KNX) allowing Machine to Machine comunications. http://blog.qt.io/blog/2017/08/14/qt-for-automation/ Mix this with Stellar and start to think what new things we can build out of it. Don't stop here! It is also easy to build games and apps using QML I can offer to support any project that uses this SDK, even if you want to join the competition, don't doubt to contact me. You can start getting Qt at: http://download.qt.io/official_releases/qt/

I published this as early i could so people can use it to build things. I am pushing this up now as i feel it can be a nice day for developers checking this forum.

This is awesome BTW. This would work on a Raspberry Pi Zero wouldn't it?

It is possible. Qt works in raspberry pi zero.

Stellar Qt/C++ SDK full featured.

Hi @bnogal I want to build this project but get some error on qt5.9 vs2015

bnogal

toby20130333 you got replied in GitHub. For anything i am here and there ?

LukeSkywalker

toby20130333 let me know if you are still stuck, I ported ethminer on vs 2012,2013,2015,2017 this summer so I should be able to recall any of the bugs, they come back the same no matter which project ?

toby20130333

bnogal Hi I resolve it on my Windows Vs2015 platform But Mingw is Ok,PS,What's your stellar wallet address?

bnogal

toby20130333

The best tip, seriously, would be a Qt development around Stellar. To show the power of the Qt framework and to show up the errors the SDK may have as i am only using a small percent in the wallet i developed. Anything you find out feel free to communicate me, i can work on fix that or/and merge changes.

In any case, this is my stellar address
GBI6ZAO55BYUC7ILJH3H6I4LXU4UZV5TEKBOJIL3N3SV4LTUXP3VMDCU

But checking your blog i see you can bring nice things to stellar. ?

if you guys wanna collaborate with no strings attached feel tag me along, even if itès a request to write up and idea you have it will give me ideas too and we can share the code...

P.S. not looking to steal ideas and IP lol, I have so many that I need a team to help me ?

LukeSkywalker

Let me know if you need help I have alot of experience in Qt, wrote a Flight Termination System for Nasa with it in Cali ?

Totally matches the stellar moonshot/spaceship theme ?

I'm also writing a wallet let me know if you need help or advice or anything (it's also going to be an exchange, a pos, trade analysis tools, will present an ICO and token, chat service, some games and whatever idea I will come up with)

stella 4 life ?

P.S. I still own the code and it is certified by NASA

I'm working using Qt for the last 7 years, at my job and at home as a hobby. Didn't do anything that great, i am mainly doing software to simulate systems. Right now i keep working on the wallet i developed last summer using Qt, but i would like to develop something different.
I am thinking about doing something with a raspberry pi zero w, like, a system to get paid for a picture, the system would require only to know the public address (so no danger leaving that outside home). Or share raspberry pi/android sensors data to a mqtt broker (using QtMqtt) with same concept.

Also it could be nice to develop a otg wallet on a raspberry pi zero.

But time is limited in this busy world. If you decide to do anything, i repeat myself, here i am to help. If you find any error or have any problem with the library i will try to answer as soon i can.

toby20130333

LukeSkywalker Hi! I solve it by myself on windows ,thx for you. I can trans english to chinese for your app,if you use Qt to dev.

LukeSkywalker

Can you tell i'm an eager beaver to get to the moon ?

LukeSkywalker

bnogal Hi sorry that I never came back to check for a reply. I'm surprised I got an answer actually or I would of replied sooner.

toby20130333 I am currently working on my own project, I implemented a "roll your own" version of the Qt parts that fit my GUI needs and its taking all my time.

I see your project is coming a lot quite well gratz. Perhaps there's a way I could expose your project to the web with possible interface. it has multiple functions that currently or soon will expose all aspects of steller functionality.

LukeSkywalker

your project could be used for intelligent cities which is an in thing right now.

Hi. When compiling with MinGW there is no problem, but when compiled with MSVC2015, there are quite a few errors. Is there a compatible version for MSVC?

bnogal

Hello, Thanks for giving it a try.

You are right, I don't use msvc to compile anything, it works with GCC (MinGW) and clang. if msvc is giving problems should be easy to fix it, as i didn't use anything too modern, i can try to check it. If you work with GCC your software will compile easier on other platforms (except for the evil google, they want you to use clang)

In the other hand, i am currently writing an example of using the library step by step, later i will focus on documenting each function, but almost everything uses same API as java SDK (with some adaptions to make it more Qt friendly), hope to have it in the next weeks as is already half done. If you need any help, here i am ?

Also if you want to contribute feel free to open issues, suggestions and/or solve them ?

EDIT:

I gave priority to fix it to work with MSVC2017, it may work with MSVC2015. Checkout last master.
I also merged some changes that got lost in an offline computer i have. I did some order in the repository cleaning branches.

Hope it helps.

Dear bnogal. Thanks for such a great library. I was able to compile using msvc2015. If I have any questions, I will not hesitate to ask you. An observation, if you need to use openssl within the application you might have problems with the objects generated when trying to link since there are similarities in the names of the functions that use sha1.
