Passing C++ pointer to callback doesn't compile, such as "this".

[vdcoder]

Built with:

c:\cheerp\bin\clang++ -target cheerp -cheerp-mode=wasm -cheerp-linear-heap-size=128 -cheerp-wasm-loader=loader.js -o output.wasm main.cpp -g -cheerp-sourcemap=output.js.map

Bare example:

include <cheerp/client.h>

include <cheerp/clientlib.h>

class [[cheerp::genericjs]] foo { public: void StartTimer(); private: void MyMemberFunction(); };

void foo::StartTimer() { client::setInterval(cheerp::Callback([this](client::Event* e){this->MyMemberFunction();}), 1000); }

void foo::MyMemberFunction() { client::alert(L"Hello"); }

foo * pFoo;

[[cheerp::genericjs]] void webMain() { pFoo = new foo(); pFoo->StartTimer(); }

Error:

c:\cheerp\bin/../include/c++/v1\functional:1570:9: error: Cheerp: Wasm function 'operator()' cannot take parameter '' of non-wasm type 'client::Event ' _Rp operator()(_ArgTypes...) const; ^ c:\cheerp\bin/../include/client\cheerp/client.h:73:11: note: in instantiation of template class 'std::function<void (client::Event )>' requested here new std::function(func));

Do you know why I cannot do add-apt-repository, I have latest Kubunto, from today.

Thanks,

You need to use the Nightly build PPA, the release PPA does not support bionic for now.
