After running the long and huge GQRX install, here is the output for these links

Code:

scott@scott-P5QC:~$ ls -l /usr/lib/x86_64-linux-gnu/libboost_system.so
lrwxrwxrwx 1 root root 25 Apr  8 11:52 /usr/lib/x86_64-linux-gnu/libboost_system.so -> libboost_system.so.1.58.0
scott@scott-P5QC:~$ ls -l /usr/lib/x86_64-linux-gnu/libboost_system.so.1.58.0
-rw-r--r-- 1 root root 14496 Apr  8 11:54 /usr/lib/x86_64-linux-gnu/libboost_system.so.1.58.0
scott@scott-P5QC:~$

Firefox and other programs do still startup after installing GQRX.
I suppose the GQRX developer has made an error in the programming?

this is not a programming but a linking error.
you can check link related issues using ldd:

Code:

ldd /<path-to>/gqrx

This whole troublesome mess came about because GQRX stopped working, complained of libboost error.

My next step is to try GQRX again and wonder what will happen.

This is the link, and how to do this.

Did you check this?

sort of moot now, the reinstall os is hosed.
Too many errors. I had no sound, an hda intel chip, module error not loaded. Followed a link to fix, that broke the mouse on rebooting.

And the software installer was broken, had to use package installer, and who knows how many other broken packages.
So I am reinstalling, wiped the 20gb OS partition complete install, not an over the existing os reinstall.

sdowney717 · 06-14-2016, 08:19 AM

new install os sound and mouse working.
Installing gnome now.
For some reason 'software installer' hangs in unity?
Trying to install chrome now and before, a square box with a ? and a line run in the middle, hover over and it says 'waiting to install'.
I had a window and had clicked install, it runs a little the window closes and that is that.

Last time I had to install chrome using dpkg from terminal. Same now? Maybe gnome can do this.

yes gnome was able to install graphically using 'package installer'
From Firefox, save as a deb file, then open the location, right click, select 'software installer'. In gnome an added choice is 'package installer', which works.

'software installer' is hosed', broken for me. Click the install button a little blue progress bar appears in the button for about one second and goes back to the solid blue button. I only tried this for Google Chrome.

off hand, the sound 'fix' posted here broke my system the second time.
I had no audo, just a dummy device at the time.

Man you're brave, I know I would have given up and searched for another distro, or at least I would have get rid of this infamous Gnome

I do run Linux mint 17.3 and it is real solid. Use the cinnamon desktop.
I have that for a navigation PC. I like it a lot.

I bought a cheap rtl-sdr usb dongle off Ebay. Was hoping to have it give me ships positions using AIS.
Alas, it is not detecting any marine signals. It barely picks up FM radio.
I could barely hear a garbled indistinct NOAA marine weather out at the boat.

For some reason has the sensitivity of a brick.

That was the reason I was wanting GQRX to work to test the thing.
I did get SDR# to work in windows, and for a time GQRX in ubuntu, and the result was the same, pretty much no marine VHF works.

I have two marine radios, and they both pick up well the NOAA weather broadcast. And the handheld VHF marine radio has a little tiny antenna.Works anyway fine.

If I use the handheld to broadcast say channel 13, the rtl-sdr device shows on the waterfall the signal, but no sound whatsoever, no white noise, just silence. I set it to NFM. If set to AM, a garble almost inaudible voice is heard.

So hold key down to transmit, rtl-sdr detects a signal and tuned in but pure silence.
