I would like to use FreeBasic to work with an MQTT server. Eclipse-Paho has a library package for Windows for use with C and I need to convert the Library Files.
There are 6 Header files, Two are master header files and the last two are included inside the first two:
MQTTAsync.h - This is the Master Header File I need for Non-Blocking Communications
MQTTClient.h - Do not Need this Master Header File.
MQTTClientPersistence.h - This file is included in both above Master Header Files
MQTTProperties.h - This file is included in both above Master Header Files
MQTTReasonCodes.h - This file is included in both above Master Header Files
MQTTSubscribeOpts.h - This file is included in both above Master Header Files
These Header files are in the attached .zip file.
Location of All Source Files for this MQTT Library:
https://www.eclipse.org/downloads/download.php?file=/paho/1.4/eclipse-paho-mqtt-c-win64-1.3.0.zip (https://www.eclipse.org/downloads/download.php?file=/paho/1.4/eclipse-paho-mqtt-c-win64-1.3.0.zip)
I was thinking of writing a conversion program to automatically convert these so I could use it for converting future updates.
I am looking for pointers, help, or both and am willing to provide information on MQTT if you are interested. At this time, this is NOT a commercial project although MQTT is widely used in many industries.
Thank you,
Peter House
I have attached a copy of the latest FBFrog.exe along with the original *.h and converted *.bi include files.
FYI
If you had tried to compile FBFrog yourself using WinFBE then you would have run into trouble because there was a bug in WinFBE that prevented the compiling of all of the individual *.o object files when creating the FBFrog project. That bug is fixed and I will upload a new version of WinFBE shortly.
Next problem will be the nasty business of import libraries.
BTW the translation of
char struct_id[4];
to
struct_id as zstring * 4
is wrong.
It must be:
struct_id(3) as byte ' (3) = 0 to 3, i.e. 4 elements
zstring * 4 only leaves you to write 3 characters because of the null terminator.
Paul and Jose,
Thank you so much - I will work on this and see if I can get it the rest of the way to working. I've written a bunch of C code under Linux to work with this library - it should be fun to get it working with FB under Windows.
I will keep posting as it goes . . .
