Re: Error undefined symbol: UP while installing Readline on wsl (Ubuntu 20.04.6 LTS)

    Hi Hiroo,
      
      ChatGPT helped me to fix the problem with Readline Library
      
      +++
      How to fix "awk: symbol lookup error:
      /usr/local/lib/libreadline.so.8: undefined symbol: UP" while
      ./configure and make
      in WSL 2 (Ubuntu 20.04.6 LTS) on Windows 10
      
      Avoid Modifying Read-Only System Libraries: Since the
      /usr/lib/wsl/lib/ directory appears to be read-only,
      always aim to create symbolic links in a user-writable directory
      like ~/custom_libs.
      
      1) Create a directory in your home folder (or another writable
      location) to hold your custom libcuda files.
      mkdir -p ~/custom_libs
      
      Since you cannot modify the /usr/lib/wsl/lib/ directory directly,
      you can create a symbolic link in your custom library directory
      and ensure that it’s recognized by your system.
      
      2) Create a symbolic link in this directory that points to the
      original file:
      ln -sf /usr/lib/wsl/lib/libcuda.so.1 ~/custom_libs/libcuda.so.1
      
      Recheck the Symbolic Link: Make sure the symbolic link in your
      ~/custom_libs is pointing correctly:
      ls -l ~/custom_libs/libcuda.so.1
      
      3) Use the custom library path. To use the library from the new
      location, you can set the LD_LIBRARY_PATH environment variable to
      include your new directory. You can add this to your ~/.bashrc or
      ~/.bash_profile so that it is set automatically when you start a
      new shell session:
      echo 'export LD_LIBRARY_PATH=~/custom_libs:$LD_LIBRARY_PATH'
      >> ~/.bashrc
      source ~/.bashrc
      
      4) Verify the Symbolic Link. Confirm that the symbolic link points
      correctly to the original library:
      ls -l ~/custom_libs/libcuda.so.1
      
      You should see something like:
      libcuda.so.1 -> /usr/lib/wsl/lib/libcuda.so.1
      
      5) Verify the Environment Variable:
      echo $LD_LIBRARY_PATH
      
      6) Try running ldconfig again without errors:
      sudo ldconfig

I am using wsl (Windows Subsystem for Linux) on my notebook Ubuntu 20.04.6 LTS
...
My goal is to successfully compile a run (Mathemagix is a free computer algebra and analysis system):

You already have GNU readline installed.  What you need is the header files.

sudo apt install libncurses-dev libreadline-dev

I hope this helps.
