Compilation error about gr-lora_sdr HOT 13 CLOSED

Hi,

I would suspect an issue with the version of either boost or gcc. The file environment.yml provide the full description of the conda environment used. You can first try to use the matching versions for libgcc, libgcc-devel, gcc_linux-64, gcc_impl_linux-64, gxx_linux-64, gxx_impl_linux-64, boost and boost-cpp. Another option is to duplicate this conda environment and use it to build and use this module.

Let me know if having the matching versions of the library fixed the building issue, or if you have difficulties with the duplication of the environment as I have never used this module on Arch Linux.

Thank you for your prompt response. Yes, I think you are right that I have a software version mismatch. My best bet is to try Conda. I will give it a go. Again, thank you for making available this very useful tool for the LoRa research community.

hello，Thank you very much for this file and it real helps tp learn about gnuradio.However, when i tried to run make i meet this problem：

CMake Error at python/cmake_install.cmake:48 (file):
file INSTALL cannot find
"/home/LEELA/desktop/gr-lora_sdr/build/python/init.pyc": No such file
or directory.
Call Stack (most recent call first):
cmake_install.cmake:51

What kind of problem it is? I run it with VMware with Ubuntu 20.04.3

Hello @Lijinyudoudou,
did you received any warning/errors when executing the cmake .. command in your build folder? Did you build gnuradio using pybombs, conda, from source, or with a different method?

from gr-lora_sdr.

hello， when cmake .. there is no warning or errors , and I install gnuradio with ppa installation.

from gr-lora_sdr.

@Lijinyudoudou can you provide the output of the cmake .. command as well as the output of the make command after deleting the content of the folder <path_to_repository>/gr-lora_sdr/build/?
If you can also provide the file python/cmake_install.cmake that is causing the error, that would be helpful.

It now seems to have issue with the characters '桌面' in your installation path.

from gr-lora_sdr.

so Should I install ubuntu in english? This characters just desktop in Chinese..

from gr-lora_sdr.

Or maybe installing the module in a path that doesn't includes Chinese characters may fix it.

@tapparelj
Thank you very much. I have changed the language to english and tried again with git .
I have to install liborc-0.4-dev and then later i have installed this Module successfully.

sudo apt-get install liborc-0.4-dev

Thank you for your time and answer. It really helps.

@Lijinyudoudou Nice to hear, let me know if you run into any other issues.
