If you aim to participate in Boost development, the only obligatory communication channel is the Boost mailing list
You don't have to use any of Gitter, Slack
For GIL specifically, I'd suggest to use the dedicated boost-gil list
Yes, for Slack you need an invite. Do you see the topic line of this room? There should be links
I should have stick one in the README.md
Pull requests are welcome :-)

hi everyone
I am Ashish Vishal, a student of IIT(BHU).
I am interested in image processing so I want to contribute to BOOST.GIL
project in GSoC 20. I am having a decent knowledge of C++ and image processing.
Below is the link of my codeforces, CodeChef and hackerrank handle on which I have submitted some solutions in c++.
codeforces: https://codeforces.com/profile/ashishvishal78
CodeChef: https://www.codechef.com/users/ashishvishal78
hackerrank: https://www.hackerrank.com/ashishvishal7810

I have recently done a project on image processing in the technical fest (Technex) of IIT(BHU) and was the first runnerup of the event. The project code is uploaded on my Github profile.
Below is the link of my GitHub repo

Hello, @ashishvishal78 we have got new GIL channel on slack which would be a more appropriate place for any discussion now onwards as we are slowly shifting there from gitter for GIL channel

thanks for inviting me

FYI, on cpplang.slack.com, apart from #boost and #boost-gil channels, there is also Boost-wide Google Summer of Code channel. Feel free to join #boost-gsos
You can join cpplang.slack.com via https://cppalliance.org/slack/

Hello Everyone, i have recently joined this channel, I wanted to participate in GSOC by contributing in this project. I had a descent ides on Image Processing, C++ and wanted to actively contribute in this open source community.
Manav-Kumar
@Manav-Kumar
Can somebody guide me on it.
Mateusz Łoskot
@mloskot
@Chinmay-Manas First things first https://lists.boost.org/Archives/boost/2020/02/248236.php then Boost wiki on GSoC, then GIL README and links there
If you have specific questions, post to Boost (or boost-gil) mailing list
See the README or topic of this room for link to slack channels

@mloskot, Can you please send me invite link for slack group.

@mloskot Seen your message on mail list. I assume you have run the test under ASan and UBSan with the latest Clang. I had observed a codgen regression in VS2017 that took me a while to investigate https://developercommunity.visualstudio.com/content/problem/342397/x64-optimization-codgen-bug-in-latest-compiler-ver.html and while it is seems to be fixed in VS2019 it is still not in VS2017. I may suggest to find an older build of VS2017 (<=15.7.5) and see if the bug reproduces there.
Pranam Lashkari
@lpranam
I would suggest you to join the slack channel @Kojoley
And continue conversation there...

@lpranam I do not have slack and do not want to use it

@mloskot

I do not have slack and do not want to use it

@Kojoley I understand not everyone is keen in using Slack. I moved there as all other Boost'ers hang out there, it is properly archived, convenient. I don't force anyone to move along, I just may not hang out on Gitter as often myself.

@Kojoley I dUBSan builds (undefined, integer, nullability) on Linux, they pass, but I admit I did not checked their detailed output yet. Thaks for the pointers, I will follow those leads

Hello everybody

hi
Mahmoud Ahmed
@mahmoudahmedd

I am Mahmoud, studying Computer Science at the Cairo University with a graduation date of 06/2021.

I have been trying for a week to link boost library (boost_1_69_0/boost_1_72_0) with visual studio 2010 or 2013 to solve Programming competency test

Mateusz Łoskot
@mloskot
sorry, this is not a general Boost support channel

But I do not know what is the problem
I watched many videos...
I followed the necessary steps...
But I don’t know what is the problem

@mloskot

to link boost library

FYI, there is no such thing as a Boost library.
Boost is a collection of C++ libraries!

Mateusz Łoskot
@mloskot
@mahmoudahmedd As you've said the word GIL, yes, this is the right channel, although we are moving to #boost-gil on Slack

Back to your question

to link boost library

GIL is header-only, there is no linking against any GIL binaries

Mahmoud Ahmed
@mahmoudahmedd

Well, I'm going to ask another question.
Can i slove "Programming competency test --- Generic Image Library"

Using another library?

It is a simple library that helps me read bitmap images...
Mateusz Łoskot
@mloskot

@mahmoudahmedd second issue

with visual studio 2010 or 2013

If you read the https://github.com/boostorg/gil/#requirements you will learn GIL requires C++11 since Boost 1.68 release

You should know your compiler/toolset of your choice to be able to tell if it does support C++11 or not
There will be no time for teaching you how to use compilers during GSoC

Using another library?

Well, the competency test is clear, it says "Using latest Boost.GIL..." and it says "...using latest Boost.GIL." again

There is alternative competency test suggested, which does not have to use GIL but metaprogramming techniques
Now, given that it is late into GSoC program and some students have been working on their proposals and competency tests since January, changing or relaxing competency test now is not the right thing to do.
I believe that answers your question
Mahmoud Ahmed
@mahmoudahmedd

There is alternative competency test suggested, which does not have to use GIL but metaprogramming techniques

Yes, I have read it, but to be honest with you
I did not understand the required
But the first (simple convolution filter) test was considered rather simple

Well I will try again
Thank you Mr Mateusz :)
Mateusz Łoskot
@mloskot
Well, I have to say basics of metaprogramming like using typelists, finding element in a typelist using a library like Boost.MP11 mentioned there, is quite a requirement for contributing to GIL.
GIL is a non-trivial highly templated code
