Hello.

I tried to compile and run jsclient, but I ran into a number of problems. Please help me solve them.

First, I performed the actions described in the corresponding README.md. But jsclient did not compile with the latest version of emscripten (3.1.64):

sreda@kamelusz-desktop:~/dev/emsdk$ ./emsdk install latest
Resolving SDK alias 'latest' to '3.1.64'

em++: error: legacy setting used in strict mode: USE_PTHREADS

So I decided to use an older version of emscripten (3.1.29):

sreda@kamelusz-desktop:~/dev/redemption/projects/jsclient$ em++ --version
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.29 (43074846f216abad2a1c35b5a631f2a9481d9e07)

jsclient compiled, albeit with warnings:

For debugging purposes, I slightly changed the Transport::do_send function. It looks like this in my case:

void Transport::do_send(const uint8_t * buffer, size_t len)
{
    LOG(LOG_DEBUG, "Transport::send %zu bytes (total %zu)", len, output_buffer.size() + len);
    hexdump(buffer, len);
    this->output_buffer.insert(this->output_buffer.end(), buffer, buffer + len);

    LOG(LOG_DEBUG, "Transport::send complete");
}

But when I tried to launch jsclient, I got an error:

Note that there is no debug output after adding bytes to output_buffer inside modified Transport::do_send function.

Please tell me how to get workable jsclient? I suspect that this behavior occurs due to unsuitable versions of emscripten and clang:

sreda@kamelusz-desktop:~/dev/redemption/projects/jsclient$ clang++-16 --version
Ubuntu clang version 16.0.6 (23ubuntu4)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

sreda@kamelusz-desktop:~/dev/redemption/projects/jsclient$ em++ --version
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.29 (43074846f216abad2a1c35b5a631f2a9481d9e07)

Which versions of emscripten and clang are you using to build the client? How do you assess the stability of this approach of using RDP in a web browser?

It seems that jsclient works after switching to emscripten 2.0.25 😮

Update.
Nope. It successfully connected to rdpproxy, but there is no image.
