3. Setup MSYS2 (Run in MSYS2 shell)

    c. cd libserialport
    d. ./autogen.sh

I have an FTDI USB cable attached, USB Serial Port (COM3)

I am not sure how to proceed, I have tried the code on my main computer (not a virtual machine) and the same error...

I have now tried on the same computer running Manjaro: -

sudo pacman -S git gcc make autoconf automake libtool
cd ~/Downloads
git clone git://sigrok.org/libserialport
cd libserialport/
./autogen.sh
./configure
make
sudo make install

Compile examples and run list-ports: -

cd examples/
echo $PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/home/pauls/Downloads/libserialport/
echo $PKG_CONFIG_PATH
make
ls
./list_ports

Error:

./list_ports: error while loading shared libraries: libserialport.so.0: cannot open shared object file: No such file or directory

I am still using an FTDI serial cable...

Update: -

pamac install libserialport
pacman -S libserialport
cd ~/Downloads/libserialport/examples/
./list_ports

Output: -

Getting port list.
Found port: /dev/ttyUSB0
Found 1 ports.
Freeing port list.

Why did it not install after compiling the library??
