build issue under linux

[Pourya Shirazian]

Hi, 

I am very new to OpenSurgSim and got introduced to this fantastic project at MMVR conference.

I am trying to build the system under Linux Ubuntu but there are errors for YAML-CPP lib:

undefined reference to `YAML::detail::node_data::mark_defined()'

Please advise.

Thanks,

[Christos Bergeles]

Hi Pourya,

I had the same issue and ended up avoiding to build the tests. You can unset the flat with cmake. Hope that helps.

Thanks yes I managed to build it as well.

Did you manage to build the examples as well?

Pourya and Christos,

Have you installed our version of yaml-cpp [1]? CMake should have
complained if this isn't installed, but just wanted to make sure.

Ok, so I managed to solve it.

In the CMakeLists.txt contained in the examples folders, there is no cmake directive to link to the yaml-cpp library (under LIBS). Speculating here, but it may be because according to your log commits the library was removed from the THIRD_PARTY libs.

I put up a branch (fix/yaml-examples) that I think does what you are
describing. Could you check it out and verify that this fixes your
issue? I also attached the patch if that is easier.

If this isn't what you did, could you submit a patch?

Hi Paul,

It still does not work. There was another issue with Yaml not having a Find**.cmake file, but I had adapted one from the net (attached).

I still get linking errors, but it may have something to do with the YAML_CPP directory being undefined - I recall the set variable being YAMLCPP without underscore. I can't take a better look right now (I am reading through the examples), but I should in a couple of days. Also, the Stapling example does not compile out of the box, giving:

 The binary directory

     /home/cbergeles/src/OpenSurgSim/build/Examples/ExampleStapling

   is already used to build a source directory.  It cannot be used to build

   source directory

     /home/cbergeles/src/OpenSurgSim/Examples/ExampleStapling

The error persists even if I erase the directory.

Best,

Christos

My bad. Example stapling is building fine!

Christos, for packages built with CMake (like OpenSurgSim and Yaml-cpp),
a Find**.cmake is not the preferred way to find the package. These are
used to find dependencies that are not build with CMake. The way we have
yaml-cpp setup right now, does not require the Find*.cmake.

Would it be possible to setup a time to work through your issues? I
think it might be a faster way to figure out what is going on.

Hi,

Sure, that would help. Just let me know. Due to the time difference any time you suggest is probably ok. Skype: c.bergeles

Thanks,
