No, you shouldn't leave that setup like that, qmicli is still crashing.<br>
<br>
It looks like your distribution isn't using /usr/lib by default for<br>
libdir, which is why this is breaking like this. Instead of the<br>
configure with only --prefix, do the following:<br>
<br>
// clear your previous installation that you did with --prefix=/usr<br>
$ sudo make uninstall<br>
<br>
// now configure also specifying --libdir, e.g. I would bet you're<br>
using Ubuntu or similar, so:<br>
$ ./configure --prefix=/usr --disable-static --libdir=/usr/lib/x86_64-linux-gnu<br>
$ make -j8 && sudo make install<br>
<br>
// and now retry the qmicli command, e.g.<br>
$ sudo qmicli -d /dev/cdc-wdm0 -p --nas-get-signal-info<br>
<br>
<br>

> i need a cid to execute too? ie execute a similar command "sudo qmicli -d /dev/cdc-wdm0 -p --nas-noop --client-no-release-cid" to get cid and then use the cid in te commnad inside the loop ?<br>

<br>
You could allocate a DMS client also for those, e.g. using --dms-noop<br>
instead, but well, if it's only 2 commands and you're not going to<br>
poll them over and over, you could just run them without the explicit<br>
client allocation logic.<br>
