Error while loading shared library libOgrePaging.so.1.9.0 (Ubuntu 17.04) #13

Closed RAD750 closed 6 years ago

RAD750 commented 7 years ago

Hello, I have installed RoR with your scripts which seemed to work perfectly (no errors at all). I can run the configurator with no problems, but when I click on "save and load" it crashes. If I launch RoR directly from command line, I get this:

jacopo@ubuntu:~/rigs-of-rods/install/bin$ ./RoR
./RoR: error while loading shared libraries: libOgrePaging.so.1.9.0: cannot open shared object file: No such file or directory

Is this something related to Ubuntu 17.04 or something else broke? I am sure I ran all the scripts in order... Is there any other file I can send or things I can do to troubleshoot the problem?

By the way, I had to modify the content.sh script with the new URLs, since it gave me a 404 error. The URL apparently changed from downloadcdn.rigsofrods.org to dl.rigsofrods.org ;-)

Thanks in advance for troubleshooting.

I am also having this error when trying to run the game. I am also running Ubuntu 17.04.

Hello.

UPDATE1: Search the OGRE build directory for file "libOgrePaging.so*". If you find it, try copying it to the directory where "RoR" binary is located. If you don't find it, find and post "CMakeCache.txt" file so I can take a look if the module was even selected for building. Then I'll need to see OGRE's build log if you can find it, but I can't guide you - I don't know where it's saved.

ORIG POST: I'm not familiar with the linux scripts (I'm a Windows developer), but my guesses are:

I'll get back with more info.

I tried moving libOgrePaging.so and libOgrePaging.so.1.9.0 to the RoR binary and kept getting the same error. I have both the Rigs of Rods CMakeCache.txt and the Ogre CMakeCache.txt Rigs Of Rods CMakeCache.txt Ogre CMakeCache.txt

@Ninja5tyl3 Use http://man7.org/linux/man-pages/man1/ldd.1.html to see what *.so files RoR requires and where is it looking for them.

Also try:

Figured out what is happening. libOgrePaging.so and libOgrePaging.so.1.9.0 are located in "wherever-RoR-is-installed/install/lib/" while the executable is looking in "/usr/lib/x86_64-linux-gnu/". Moving the libraries there fixes the issue and the game runs.

@Ninja5tyl3 - Fantastic work!! This makes 1ea 7 year old (and Dad too) very very happy that they can play the game again. Thanks for posting the fix. Cheers.
