libgnuradio-ieee802_11.so not found?

It seems you are copy-pasting random commands you find online. First, you have to find out where you actually installed the module. See if the library is actually under /usr/local/lib.

If that's the case, you could setup the environment with:

export LD_LIBRARY_PATH=/usr/local/lib:${LD_LIBRARY_PATH}
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:${PYTHONPATH}

Also run sudo ldconfig.

Hi,
please put /opt/local/lib in your LD_LIBRARY_PATH environment variable and do sudo ldconfig.

[egaebel]

That did it. I feel silly. Thank you so much!

[bastibl]

Good to hear that it's fixed

I found your work very interesting and i have tried of modify your code for implementig 256-QAM, but i have trouble.
Can you help me about 256 QAM, it's possibile to update this modulation?

I encountered the same issue, but on MAC. There is no LD_LIBRARY_PATH environment variable on MAC. How could I resolve this issue? Many thanks in advance.

[bastibl]

On macOS you should not need that. The shared library should know the full install path of the linked libraries. If you have problems, the library that cannot be found probably hasn't set its install_name.

[bastibl]

As you might have seen, the problem was that the LD_LIBRARY_PATH was not set up. Did you check that yours is correct?

If that's not the problem, you might try opening a Python session and import ieee802_11.

[bastibl]

OK, so maybe we should go 10 steps back.

• Did you download, build, and install gr-ieee802-11?
• If so, where did you install it to?

I understand that my previous post is hard to understand, but did you actually try the commands?

[bastibl]

OK, so you downloaded the source code. That's already pretty good. The next important steps are to actually compile and install the software. Since there is already a build directory, you seem to (at least) have tried something.

Please see here for installation instructions: https://www.wime-project.net/installation/
Don't just blindly copy-paste commands to the terminal and hope for the best, but make sure that it actually works. During installation, you will also see where the module ends up. I don't have Mint, so I don't know the default install paths on Mint. Then adapt your environment variables accordingly.

I'm not really sure how I can help you further with this. What you post, suggests that you are missing the basics of using a computer. Maybe you want to read a bit more about Linux and compiling software. The fact that you posted a screenshot of the downloaded source code, suggests that you don't know the difference between source code, build directory, and install path.
