Error during build

[swarmt]

Hey There!

Just wanted to test out your library and struck an error during build.

undefined reference to trimesh::TriMesh::read(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' collect2: error: ld returned 1 exit status dsl_gridsearch/CMakeFiles/dsl_grid3d_node.dir/build.make:120: recipe for target '/home/sam/robo/devel/lib/dsl_gridsearch/dsl_grid3d_node' failed make[2]: *** [/home/sam/robo/devel/lib/dsl_gridsearch/dsl_grid3d_node] Error 1 CMakeFiles/Makefile2:377: recipe for target 'dsl_gridsearch/CMakeFiles/dsl_grid3d_node.dir/all' failed

Weird... my build is successful. Trimesh is included in the package directly, so there should not be any version mismatches or anything. Do you have another version of trimesh installed on your system? It could possibly be finding that version instead of the one included in the package.

[swarmt]

Definitely no other versions of trimesh. I will try it on a clean install.

EDIT: Same issue clean install.

[swarmt]

There is something broken with the linking of libtrimesh.a. Build successfully if I supply the full path. I'll let you know when I figure it out!

[msheckells]

Okay, thanks!

I am having the same issue after following the installation instructions. I have no other version of trimesh installed. I'm on Ubuntu 16.04

I just pushed a branch called linker-test. Could you check it out and try to build it? I changed dsl_gridsearch to a static lib and linked trimesh to it directly instead of linking trimesh to the individual executables. Both this version and the old configuration still build fine on my computer, so I don't really have a good way of testing the changes myself.

[gilmoujw]

Thanks for the quick response! I deleted everything and cloned that branch and followed the installation instructions again. However, I got the same error.

Really not sure why this is happening. I will look into it tomorrow. If I figure anything out I will post it here.

[gilmoujw]

As evidenced by the error: 'undefined reference totrimesh::TriMesh::read(std::__cxx11::basic_string<char, std::char_traits, std::allocator > const&)' I believe the problem isn't linking but rather to do with the version of GCC that the static library was compiled under. I found a great explanation at: https://stackoverflow.com/questions/41134190/linker-can-not-find-symbols-but-theyre-there

I tried using the workaround described here: https://stackoverflow.com/questions/40705852/undefined-reference-to-std-cxx11basic-string-in-boost-on-travis-ci by adding add_compile_options(-D_GLIBCXX_USE_CXX11_ABI=0) to the CMake file. The errors about read went away, but new errors in the library related to ros functions appeared. I have put them below.

[gilmoujw]

I was able to get it to build by getting the latest version of trimesh2 from here and copying the appropriate files over after building trimesh2.

Did you try building the latest trimesh2 lib from source as mentioned by @gilmoujw?
