Re: [ libui ] can't open .so

Unfortunately, there are a few things going on here:
Problem 1: A typo
Yes, sorry, the ui.e library looks for libui.so.0 but the included file is named libui.so. My bad. Please rename one or the other. I will fix this in a future release.
Problem 2: Missing libraries
You may be missing a library that libui.so is linked to. Run ldd libui.so | grep 'not found' and see if anything is listed there.
However, if you're on Debian/Ubuntu/Mint this is unlikely to be a problem and libui should work out of the box.
Problem 3: Euphoria 4.1 is broken
The current Euphoria 4.1.0 build does not have its rpath set to include the local directory. This is a relatively simple fix and will be corrected when I release 4.2.
In a pinch, you can just run cd examples; LD_LIBRARY_PATH=../bin eui controlgallery.ex and it would work (assuming you fixed problem #1 above).
In the mean time, here's a more permanent solution I would recommend:
- Put any additional libraries (e.g. libui.so) you want to use in your Euphoria bin directory.
- Edit your ~/.profile file and add export LD_LIBRARY_PATH=/usr/local/euphoria-4.1.0-Linux-x64/bin to the end.
- Log out and back in for the changes to take effect.
