chrono build error on Ubuntu - irrKlang.h not found

[Robert]

I'm attempting to build Chrono from source on my Ubuntu 16.04 VM (32bit) with the following options:

Build demos

build tests

enable irrklang

enable irrlicht

enable opengl

enable vehicle

enable openmp

I'm compiling with gcc (5.4.0) in debug mode, and I get the following error when executing "make" from the chrono_build directory:

...

I have downloaded IrrKlang (1.5.0) from the official download site and installed the shared libraries in /usr/local/lib and the headers in /usr/local/include/irrklang/

I checked that the shared libraries are found in my /etc/ld.so.cache file.

Attached is a full screenshot of my cmake gui window, but I believe the issue has got to be with the following Cmake variables

CH_IRRKLANGLIB = /usr/local/lib/libIrrKlang.so

CH_IRRKLANG_SDKDIR = /usr/local/include/irrklang

I feel like I've hit a wall with this, so any help would be appreciated.

Thanks,

Robert

Today I was able to get Chrono to finish building!

Somehow I was in a detached head state in my local repo, but I checked out master (Chrono 3.0.0), and deleted my cmake cache. When reconfiguring in the Cmake-gui, it no longer required me to have the IrrKlang option checked to be able to build the vehicle module, so I left it unchecked and don't really plan to test building with it. Everything built successfully but i was getting errors with a lot of the demos. Most notably, all the Irrlicht and vehicle demos were crashing with a *** Stack smashing detected *** error. At this point I had the Irrlicht 1.8.2 library installed.

I downloaded and installed Irrlicht 1.8.4 and that has fixed all the demos that I've tried so far. Hopefully this is useful for anyone on Ubuntu running into similar errors.
