I going to assume you're running Apache web server on a Debian-based Linux distribution. Here is what I typically do.

Step 1: Download Euphoria 4.1 64-bit from GitHub.

$ wget -q https://github.com/OpenEuphoria/euphoria/releases/download/4.1.0/euphoria-4.1.0-Linux-x64-57179171dbed.tar.gz 

Step 2: Extract only the bin and include directories to /usr/local/euphoria-4.1.0-Linux-x64.

$ sudo tar -C /usr/local -xzf euphoria-4.1.0-Linux-x64-57179171dbed.tar.gz euphoria-4.1.0-Linux-x64/{bin,include} 

Step 3: Symlink the executables from bin directory into /usr/local/bin (which should be in the environment PATH).

$ cd /usr/local/bin 
$ sudo find /usr/local/euphoria-4.1.0-Linux-x64/bin -type f -executable -exec ln -s {} \; 

The trick here is that the eu.cfg in that package points to the directory where we put the files, including the -i option which indicates where to look for include files.

$ cat /usr/local/euphoria-4.1.0-Linux-x64/bin/eu.cfg 
[all] 
-d E64 
-eudir /usr/local/euphoria-4.1.0-Linux-x64 
-i /usr/local/euphoria-4.1.0-Linux-x64/include 
[translate] 
-arch ix86_64 
-gcc 
-con 
-com /usr/local/euphoria-4.1.0-Linux-x64 
-lib-pic /usr/local/euphoria-4.1.0-Linux-x64/bin/euso.a 
-lib /usr/local/euphoria-4.1.0-Linux-x64/bin/eu.a 
[bind] 
-eub /usr/local/euphoria-4.1.0-Linux-x64/bin/eub

Anything you're installing by hand should go into /usr/local/lib, which should be in the default search path for shared libraries on common distros like Debian, Ubuntu, Fedora, etc.

Euphoria relies on dlopen() so reading that man page helps understand how it's searching and why the loading can fail.

Unfortunately the man page outright states, "if dlopen() fails for any reason, it returns NULL." So working out "cannot find" versus "cannot load" can be tricky.

If you've got your libraries in /usr/local/lib, if they still aren't loading, run them through ldd and look for instances of not found. These are dependencies you need to resolve.

If you're missing any dependencies, you'll get output similar to this:

$ ldd /usr/local/lib/libname.so | grep 'not found' 
  libsomething.so => not found 

If you're on Debian/Ubuntu/etc. and are unsure which package is required to install the missing library, you can try searching with apt-file.

$ sudo apt install apt-file 
$ sudo apt-file update 
$ apt-file find libsomething.so
