LimeNET micro RPI/CM3 8 GB build from source

[9a4db]

Hello,
can you advise please LimeNET micro RPI/CM3 8 GB
build from source.

I was following;
git clone https://github.com/qradiolink/qradiolink
cd qradiolink/
git checkout master
mkdir -p build
cd ext/
protoc --cpp_out=. Mumble.proto
protoc --cpp_out=. QRadioLink.proto
cd ../build/
qmake ..
make
./qradiolink

protobuf and Qt5 installed

You need libconfig++ and libconfig++-dev packages to be installed prior to building. See the list of all dependencies in the README, and try to apt install them all before building otherwise you'll have to repeat this step many times.

[9a4db]

Thank you,
afer running:
sudo apt-get install gnuradio-dev protobuf-compiler gr-osmosdr gnuradio libvolk1-dev libvolk1-bin libprotobuf17 libprotobuf-dev libopus0 libopus-dev libspeexdsp1 libspeexdsp-dev libpulse0 libpulse-dev libcodec2-0.8.1 libcodec2-dev libasound2 libasound2-dev libjpeg62-turbo libjpeg62-turbo-dev libconfig++9v5 libconfig++-dev qt5-qmake qt5-default qtbase5-dev libqt5core5a libqt5gui5 libqt5network5 libqt5sql5 qtmultimedia5-dev libqt5multimediawidgets5 libqt5multimedia5-plugins libqt5multimedia5 libftdi1-dev libftdi1 libsndfile1-dev libsndfile1

only missing was: libftdi-dev

After that, make started well, with just few warnings
After approx 10 min, ended with:

/usr/bin/ld: QRadioLink.pb.o:(.data.rel.ro+0x26c): more undefined references to `google::protobuf::Message::SpaceUsed() const' follow
collect2: error: ld returned 1 exit status
make: *** [Makefile:439: qradiolink] Error 1

Here already have protobuf:

libprotobuf-dev is already the newest version (3.6.1.3-2+rpi1).
The following package was automatically installed and is no longer required:

Any more suggestion?

[kantooon]

Hmm, that's a weird one, never seen it before. It seems the linker can't link into libprotobuf-c++. Which branch are you building off? I've made changes lately to that part that may be incompatible with your version of libprotobuf (can you please check and post its version?), so I suggest the following:

• remove the generated *.pb.h and *.pb.cc files from ext/ dir
• clean the build directory
• check out a stable tag, latest one is 0.8.2-3: git checkout 0.8.2-3
• run the build again

You'll be missing some latest features, but the build may work with that version. Alternatively, you can download a source tarball from the releases page, 0.8.2-1 and above until you hit 0.8.3-alpha

[9a4db]

Thank You,
I am looking for basic functionality only... it is LimeNET micro after all :)
Will try advised later today...

Have stable running Soapy, now just need TX/RX application

Helo Adrian,
Problem persist:

I used qradiolink-0.8.2-3.zip deleted complete directory on pi and repeated:

protoc --cpp_out=. QRadioLink.proto
cd ../build/
qmake ..
make

Can you post your version of libprotobuf? I am using libprotobuf17 here, make sure you are not using libprotobuf-lite17.
To completely avoid this, fall back in release versions until you stop getting those errors. There should not be too many tries.

Have this one, have no clue is it good enough :)

[9a4db]

Tested with:
qradiolink-0.5.2
no luck on start gsm.h trouble
manage to find only some arduino libs
and
qradiolink-0.8.1-9
qradiolink-0.8.2-rc1
having the same problem like
qradiolink-0.8.2-3

Guess, now is turn for someone more proficient on RPI 👍

[kantooon]

I forgot to ask the most basic question: which version of Debian is your OS based on? Debian 10 (current stable) is supported, so if your version of Raspbian is based on Debian 10 then they are doing something strange to libprotobuf and/or protoc.

[9a4db]

I am using 2019-09-26-raspbian-buster 3,7 GB image,
which have enough space up to 8 GB on CM3 from LimeNET micro package.
Have no clue on which Debian version is based.
Lime and Soapy utility are up and running.

libprotobuf-dev is already the newest version (3.6.1.3-2+rpi1).

Sorry for the delay. It seems to me that the code generated by protoc is incompatible with the version of libprotobuf being linked. Can you please post the output of ** protoc --version ** ?
It looks like there is a need for reproducible builds, including on Raspbian, but I don't have enough resources right now to do that. This issue pottentially affects all arm64 platforms.

[9a4db]

Thank you Adrian,
For temporary solution I used Soapy Remote and now able to run at last Cubic SDR.
For example SDRangel is crashing on Soapy Remote device selection.
My RPI used for testing is at moment busy feeding FR24 instead of broken F- hardware.
Will let you know when able to compile on RPI again.
But I can try to compile from source on Ubuntu 18.04 and try Soapy Remote with
qradiolink / if Soapy Remote is supported?
Wish you all the best for new 2020. and thank you for the good SW work and efforts.

Djani, I don't know about Soapy remote. Theoretically it might work, but in practice it's always harder. Don't expect it to work perfectly though, or even well enough. Had some weeks to test my setup, when confronted with the real deal all this theoretical stuff goes out the window, the reality is my setup does not work well enough at the moment. Things may improve in the future or they may not. Don't rely on it for anything serious, at the moment it's good when you are bored and want to try various things.

[9a4db]

Dear Adrian, that is good enough....
Really appreciate your efforts.
