Support iOS

[shockcao]

Hi all,

Is there any plan to support on Android, iOS and Windows?

[dtikhonov]

Yes: we plan to support all of those -- however, not in the nearest future. Android is likely the easiest of the three, as it is based on Linux.

Pull requests are welcome -- and you get fame and glory! :)

[shockcao]

thanks, I've stripped a pure QUIC sdk from proto-quic for Android & iOS but based on Google base with a big bulk, glad to see the smaller sdk using C program. I will try to make lsquic-client support Android/iOS whenever I have time.

[amoldeshpande]

hi @dtikhonov , I have a windows version at https://github.com/amoldeshpande/lsquic-client

I am able to compile in debug and release as well as pass tests in debug mode. Ran http_client and was able to get a web page back.

I'm about 1 commit behind so I'll need to update before I make a pull request. Before I do that, I wanted to point out that I had to make a lot of changes due to Microsoft's pigheadedness about never properly supporting C99 (To be fair, there were also GCC extensions that I had to deal with)

Those diffs are relatively minor individually, so it's honestly not too bad.

Before I go through the torture to update and make a pull request I want to be sure that you guys are OK accepting those types of changes :-) They will force you to code slightly differently going forward if you want to keep the Windows version alive.

Thanks. Edit: missed a not.

[dtikhonov]

Sounds both ominous and exciting. I think we’d have to see what you propose. Looking at your branch, the changes don’t look very scary, even though there are many of them.

Submit a patch and let’s take it from there - it would be really nice to have lsquic work on Windows!

[amoldeshpande]

cool, will do. It's mostly a bunch of variable-sized arrays (or 0-length arrays) that are not supported properly in VC.
I don't have a Linux/Mac handy to regress my changes though.

[dtikhonov]

Thank you very much, @amoldeshpande, for pull #7 -- we are reviewing it.

[amoldeshpande]

@dtikhonov any news on the pull request ?

[dtikhonov]

Sorry we have been swamped a bit. My plan is to examine the patch more closely next week. I will need to set up my own Windows environment.

One thing I don’t like — and will try to change — is the moving around of functions.

[amoldeshpande]

ok, no worries. I had to move the functions because visual C++ doesn't like forward declaration of static consts. But if you have a better way to do it, that's great.

BTW Microsoft has various free VM images if you're not looking for a permanent Windows environment.

[somanybut]

@amoldeshpande, how to build lsquic-client in win7, pls descripe the building steps. thks.

[amoldeshpande]

@somanybut, It's pretty much the same steps as the Linux version. You have to compile boringssl for yourself and get zlib and openssl from vcpkg (or wherever else you get your 3rd party libraries). Make sure you exactly match the C-runtime library (static,dynamic, debug,release) for each component or you'll get linker errors.

Until my pull request goes through, please file issues at my fork.

[rperper]

@somanybut @amoldeshpande When we've merged the Windows changes into the master branch there will be released a how-to-compile-for-Windows doc.

[somanybut]

I am a java programmer, and I know little about C and C++.

@amoldeshpande @rperper thanks for your help, I'll try to compile the project. thanks again.

[stormcenter]

So , is there any Android/iOS sample project available on release or debug branch ?

[dtikhonov]

No, Android and iOS are still not supported.

[stormcenter]

I have build a arm64 arch liblsquic.a using -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES=arm64 and add pods depends on BoringSSL and I found some build errors blew when I add liblsquic.a into my test project.

[amoldeshpande]

I don't have iOS tool, so litespeed guys can give a better answer, but it looks like you may either need to turn off address sanitizer (-fsanitze=address) or add some other library related to asan to your project.

[dtikhonov]

@stormcenter, please try @amoldeshpande's suggestion, as we don't have a better one, at least for now.

[stormcenter]

Yes, I turn off address sanitizer , the error down to 5, and I'll find a zlib on iOS to complete the iOS build. Thanks

[JVHE]

@dtikhonov I ported the lsquic client on Android using the wrapping function method. I have uploaded it in my repository, but it currently only works on the ARM architecture. Many bugs are scattered so I'm not sure I can apply pull request because this is the first experience.

[dtikhonov]

This is great, @JVHE! You're right -- I also don't know how how a PR request would look. The wrapped library is in a different language with a different API.

How do you compile the library? I looked around your repo and could not find build instructions.

[Android4MediaPlayer]

@JVHE How do you compile the library on android platform?

This problem is because of the new NDK. cmake find_path with android toolchain does not work without setting some cmake vars for latest NDK (>= r19b). Anyways, I have raised a PR #132 to handle Android and it solves this problem too.

Thanks for you suggetstion, I build succes. And I got exexcutable binary :http_client. But when I push it to may android device and run http_clinet, it always report an error as follows：

can you show me why or can you show me the right way to use it?
