GPS with Sierra Wireless, Incorporated Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A (cdc-wdm0)

Hi Aleksander,
I don't remember, but after your email I recompiled with

./configure --prefix=/usr --disable-static && make
sudo checkinstall --install=no
sudo  dpkg -i libqmi_1.24.12-1_amd64.deb

but during the install I got this error:
dpkg: errore nell'elaborare l'archivio libqmi_1.24.12-1_amd64.deb 
(--install):
  tentata sovrascrittura di "/usr/bin/qmi-firmware-update" presente 
anche nel pacchetto libqmi-utils 1.24.8-1

so I did another run:
./configure --prefix=/usr/local --disable-static && make
sudo checkinstall --install=no
sudo  dpkg -i libqmi_1.24.12-1_amd64.deb

and I installed the package.

I have this situation:
locate libqmi-glib.so.5
/home/angelo/Software/libqmi-1.24.12/src/libqmi-glib/.libs/libqmi-glib.so.5
/home/angelo/Software/libqmi-1.24.12/src/libqmi-glib/.libs/libqmi-glib.so.5.6.0
/usr/lib/libqmi-glib.so.5
/usr/lib/libqmi-glib.so.5.6.0
/usr/lib/x86_64-linux-gnu/libqmi-glib.so.5
/usr/lib/x86_64-linux-gnu/libqmi-glib.so.5.6.0
/usr/local/lib/libqmi-glib.so.5
/usr/local/lib/libqmi-glib.so.5.6.0


ldd /usr/sbin/ModemManager
libqmi-glib.so.5 => /usr/lib/x86_64-linux-gnu/libqmi-glib.so.5 
(0x00007f236434f000)

after modify ld.so.conf.d/ libc.conf, issuing ldconfig with the ldd 
/usr/sbin/ModemManager I got this:
libqmi-glib.so.5 => /usr/local/lib/libqmi-glib.so.5 (0x00007ff47371e000)

finally

mmcli -m 0 --location-get

The latest stuff that I want to verify is following situation
sudo dpkg --get-selections | grep libqmi*
libqmi                        install
libqmi-glib-dev:amd64                install
libqmi-glib5:amd64                install
libqmi-proxy                    install
libqmi-utils                    install
libqmobipocket2:amd64                install

Now I have only another issue: modem-manager-gui is reporting the 3GPP 
position, but nothing about the GPS position:  but this is another story.

Thanks for your support !

cheers,
Angelo
