0001051: Module class not found due to soft links in the NED folder's path

Notes
(0001370) andras (administrator) 2018-09-18 09:14	Steps to reproduce. Create the following files: ==> x/package.ned <== @namespace(ns); ==> x/omnetpp.ini <== [General] network=inet.Foo ==> x/inet/Foo.ned <== package inet; simple Foo { @class(Foo); @isNetwork(true); } ==> x/inet/Foo.cc <== #include <omnetpp.h> namespace ns { class Foo : public omnetpp::cSimpleModule {}; Register_Class(Foo); } Build an executable simulation and try it: cd x opp_makemake --deep make ./x # works fine Then create a softlink to x, and run the simulation: cd .. ln -s x x-softlinked cd x-softlinked pwd # /home/you/.../x-softlinked (abs path w/ softlink) ./x -n $(pwd) # error: class not found
