mqtt-client-object's Issues

build script not working on macOS

Hi,

I'm trying to compile mqtt-client-object for pd on MacOS via terminal and the build script seems not to work

Error: could not load cache 
make: *** No targets specified and no makefile found.  Stop.

Thanks to the great help of @i-n-g-o I think I'm halfway to the solution. As mentioned I did the following steps:

  • cd into build/osx folder
  • cmake ../..

These steps seemed to work.

When I do the next step:

make -j 8

I can see some progress, but after 76% I get some warnings:

mqtt-client-object/third_party/paho.mqtt.c/src/StackTrace.c:112:34: warning: cast to smaller integer type 'int' from 'pthread_t' (aka 'struct _opaque_pthread_t *') [-Wpointer-to-int-cast]
                Log_stackTrace(trace_level, 9, (int)my_thread->id, my_thread->current_depth, name, line, NULL);

And after 96% I get some Errors:

Could you help me with this part as well. Thanks a lot!

dll crash on windows, trying to rebuild

Hi, I'm using mqtt_client with purr-data for a class. It works great for students working on Mac OS. On windows, we get an error:

The procedure entry point _Unwind_Resume could not be located in the dynamic link library C:\Program Files\Purr Data\extra\mqtt_client.dll

I thought I might try to recompile the library from source, but I have scant experience building on windows with mingw.

A few questions:

  • Did you all use mingw32 installed through MSYS2 to test the windows build?
  • Do you have any tips/instructions on build environment setup?
  • Have you tried this with purr-data on windows, as opposed to puredata?

Thanks!

crash on windows when publishing

Hi.

When running the external on windows (compiled with mingw) using Pd i experience crashes when publishing a value.
The exception code is: 0xc0000094. Which apparently is a division by zero (STATUS_INTEGER_DIVIDE_BY_ZERO)

Connecting and subscribing works fine.

I guess this happens somewhere in the mqtt library.

Do you have any idea what that could be?
