pack_install make error

[peter....@stud.uni-due.de]

Hello Group,

I need help installing packs in SWI-Prolog.

I want to install the mqtt pack but I only get an error while installing.

?- pack_install(mqtt).

If I understand the error correct it fails to find the SWI-Stream.h file. I found the file in my SWI-Prolog installation in the swipl/include folder.

And if I understand the gcc command then the -I parameter adds folders where the make searches for .h files. So i copied the file in swipl/ext/include, but that didn't work either.

I have found a newer Version of the mqtt pack by Sprior (https://github.com/sprior/swi-mqtt-pack) and tried to install that version, but I only get following error:

?- pack_install('https://github.com/sprior/swi-mqtt-pack.git').
ERROR: Domain error: `pack_name' expected, found `'swi-mqtt-pack''
ERROR: In:

So I am guessing that either the pack configurations or my System configuration is not correct. Can someone help me with that?

To change the pack files I downloaded them and tried to install the pack from my harddrive but that didnt't work either.

I unzipped the pack in the folder C:\mqtt and have it as a zip in C:\mqtt.zip. So I tried

?- pack_install('file://C:/mqtt').
false.

?- pack_install('file://C:/mqtt.zip').
false.

and as you can see got only false as response. So I am doing something wrong here too.

My System:

Windows x64

SWI-Prolog 7.6.4

swipl --dump-runtime-variables

CC="gcc";
PLBASE="c:/program files/swipl";
PLARCH="x64-win64";

pack swi-mqtt-pack has an install bug filed now, looks like fix in progress.

First of all, I would like to thank you for your quick answer. And I can see that there were changes in the git. But the error is still the same.

In the git (https://github.com/olsky/swi-mqtt-pack/releases) the version was updated to 1.0.7 but when I use pack_install('mqtt') it only offers me the option to download version 1.0.5.

I can download the newest version manually, but SWI-Prolog just prints false when I try to install a file from my hard drive (see first post). Can someone point out what I am doing wrong here.
