Hi! I have created a command line program: https://github.com/svetlyak40wt/cl-jslog I've tried to build it with sbcl and it worked fine. But when I compiled it with ECL, I found that right after running, it outputs following error: Condition of type: SIMPLE-ERROR The packages ((UIOP/OS . #<UIOP/OS package>) (UIOP/PATHNAME . #<UIOP/PATHNAME package>)) were referenced in compiled file NIL but have not been created Available restarts: 1. (IGNORE) Ignore the error, and try the operation again Top level in: #<process TOP-LEVEL>. Tried ECL 16.1.4 on Ubuntu and ECL 16.0.0 on OSX. What is the reason of this error, and how to fix it? -- Alexander Artemenko (a.k.a. Svetlyak 40wt) Blog: http://dev.svetlyak.ru Photos: http://svetlyak.ru Jabber: svetlyak.40wt@gmail.com
