Build fails -- ld: library not found for -lassimp

[chrisalbertson]

Building this on a MBP. All Apple software up to date. I cleaned out everything in Homebrew before I started "dumped" every package. The did ./install and after a couple hours got message quoted below. Yes I can track down the library but I figured you might want to add this to your list of dependencies

Looks like there's a related discussion here in https://github.com/ros-planning/geometric_shapes/issues/23.

I'm doubtful that just pre-installing assimp is going to be enough, though, given that we do have rosdep keys for that package:

https://github.com/ros/rosdistro/blob/39948946d46f1325806289a12914d6bdac55427c/rosdep/osx-homebrew.yaml#L5-L12

And there's the required dependency on it here:

https://github.com/ros-planning/geometric_shapes/blob/66352a742520f71e19a32139ec7463dcefe3b451/package.xml#L17

To clarify, did you find a path to success on 10.10? Was it just installing, or did you have do other stuff? (brew link -f, manipulating DYLD_LIBRARY_PATH, etc)

Anyway, thanks for trying this out and reporting your results!

I'm running macOS High Sierra 10.13

Before I started I completely removed everything to do with Home-brew but did leave homebrew itself installed

Yes I see that it is not as simple as just finding a copy of libassimp

My fall back is easy, I run Linux in a VM on my mac.

I'll test any new version of this as it would be nice to have ROS native on the Mac.

I had the same problem, and I ended up editing the link.txt in the build folder, as proposed here: https://github.com/ros-planning/geometric_shapes/issues/23#issuecomment-284830221

However after changing c++ toolchain to CLT from the Xcode.app, it stopped complaining.

As a part of my efforts to make CMake find assimp automaically I added https://github.com/assimp/assimp/blob/master/cmake-modules/Findassimp.cmake to ls /usr/local/share/cmake/Modules/ which may have something to do with it.

[mikepurvis]

There's a ticket tracking this upstream, but it's likely to be a while before there's a solution from either assimp itself or the homebrew package: https://github.com/assimp/assimp/issues/1517

I'd be delighted for a PR which is able to make ros-install-osx do the right thing, ideally without hacking on files installed/owned by homebrew packages (though installing a temporary fork of assimp from your own tap is totally fair game— please just use the rosdep file to point at it).

So I changed the -lassimp argument to the location where brew installs assimp and clang seems to find it just fine, but then I get a serious linking error concerning missing symbols.

Does anyone know what might be going wrong?
