mqtt with raspbery pi - install issues

[sshanks-kx]

Report from user:

I have the interface working on a Raspberry Pi but had some issues following the instructions and using the supplied install.sh Default kdb+ build from kx comes named q/l32arm . I needed to rename to q/l32 Otherwise error will be seen: q)\l mqtt.q '/home/pi/q/l32/mqtt.so: cannot open shared object file: No such file or directory [2] /home/pi/q/mqtt.q:2: connX :mqtt 2:(connX;3); ^ [0] () Install.sh fails Detected System

• OS: linux-gnueabihf
• TYPE: arm
• MACHINE TYPE: arm-unknown-linux-gnueabihf ERROR: OSTYPE linux-gnueabihf not currently supported by this script Please view README.md for installation instructions Issue 2 can be bypassed with: OSTYPE="linux-gnu" ./install.sh but that shows another error: ERROR: Directory 'lib' does not exist. Please run from release package The .so is located in the cmake folder

Instead of using install.sh I just did copies manually: cp q/mqtt.q $QHOME/ cp cmake/mqtt.so $QHOME/l32/

Steps

#Broker and command line tools install
sudo apt-get install mosquitto mosquitto-clients

#q lib folder comes as l32arm from Kx make sure to rename to l32
#.bashrc entries:
export PATH="$PATH:/home/pi/q/l32"
export QHOME="/home/pi/q"

sudo apt-get install libssl-dev git cmake

wget https://github.com/eclipse/paho.mqtt.c/archive/v1.3.2.tar.gz
tar -xzf v1.3.2.tar.gz
cd paho.mqtt.c-1.3.2
make
sudo make install

export BUILD_HOME=/usr/local/lib

cd ..
wget -O mqtt.tar.gz https://github.com/KxSystems/mqtt/archive/1.0.0-rc.1.tar.gz
tar -xzf mqtt.tar.gz
cd mqtt-1.0.0-rc.1
mkdir cmake && cd cmake
cmake ..

@cmccarthy1 - This is working correctly on Raspberry Pi now - can be closed out.
