3 years ago Hello, Unfortunately, I know English poorly, so I will use the translator.
Run as superuser (sudo, su, I do not know ARCH Linux ) on the command line: ldconfig and replace on unix|win32: LIBS += -lmirsdrapi-rsp

3 years ago this is the relavant ls -al output
lrwxrwxrwx 1 root root 36 Aug 17 15:27 libmirsdrapi-rsp.so -> /usr/local/lib/libmirsdrapi-rsp.so.2
lrwxrwxrwx 1 root root 39 Aug 17 15:27 libmirsdrapi-rsp.so.2 -> /usr/local/lib/libmirsdrapi-rsp.so.2.13Then you can try to replace with: -L /usr/local/lib/libmirsdrapi-rsp.so.2.13 Possibly broken links.

3 years ago Same error as firstyl mentioned. Can you just compile it for me and upload to Github releases?

This is a link to static compilation with Qt. https://drive.google.com/file/d/15_EmlQ1d__60GNXFC_QOfndGhEdVv5L4/view?usp=sharing But when running on other Linux distributions, there are more problems than when compiling a project.
Your SDRPlay 2.x driver is clearly not installed correctly.

3 years ago Now the program is starting up(thanks was infact a driver issue caused by the install script) but the controls are grayed out and I see no logs in the terminal. I can see the device showing up in lsusb.
Bus 001 Device 002: ID 1df7:3000 SDRplay RSP1a

3 years ago Which programm? Qt project?
Konradrundfunk
commented
3 years ago Yes the QT Program. So the dvbt2 software.

commented
3 years ago When starting the program, only the device selection elements are active. If the device is defined, the following graphic elements will become active. Then tune to the frequency and start, etc.
Konradrundfunk
commented
3 years ago I haven't seen any device selection option only the option to set frequency and gain.

3 years ago Now it won't build at all :/ .I have tried multiple ways to ensure that the lib is infact installed corectly and I can even see it in the ldconfig -p output: libmirsdrapi-rsp.so.2.13 (libc6,x86-64) => /usr/lib/libmirsdrapi-rsp.so.2.13. I don't know why it worked when compiled 30min ago.

3 years ago It is very strange. It is clear that the problem is not in the project. Does the device work with other programs? It is more like a hardware failure of a computer, such as a hard drive. The drive may run out of space.
Oleg-Malyutin
commented
3 years ago Now I remember. I had a similar problem with another library. I decided through - "right mouse button on the project - add a library ..." Before this "build - clean project"
Konradrundfunk
commented
3 years ago That infact did work whierdly. Thanks for now the software is looking great btw. If you don't mind I can make the instruktions more clear in the README for Arch linux users.

3 years ago I wont get a lock here. What's my mistake?
Oleg-Malyutin
commented
3 years ago This signal is too weak. From experience, synchronization starts with a gain reduction of ~ 40. Also strong reflected signal due to sub-optimal antenna orientation (or omnidirectional antenna). For starters, you can get a stable signal on a consumer TV.
Konradrundfunk
commented
3 years ago I do have a groundplane Antenna but I am trying now to get it in a better position but thats a good tip with the gain. I also will try using my V-Dipole Antenna.

Hi, I have a Sdrplay RSPA1 and tried to build with QTcreator. But I got the following errors below. I set the lib path to my lib folder since it wasn't recocnized before. I have the version 2 of the SDRplay lib installed from the website. I am on a ARCH Linux system and have compiled with g++. Thanks for your great work on DVBT2 decoding and deomoding!
