Cmake Error: No target "nabo" #223

Closed bishesh closed 6 years ago

bishesh commented 6 years ago

cmake results in an error saying that it cannot find target "nabo". I've manually set the directories of Eigen and boost. It somehow automatically finds the libnabo_DIR (the build directory, and not the install directory). My system: g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609 ccmake/cmake version 3.5.1

Below is the result with --debug-output

Running with debug output on.

@HannesSommer is that related to the issues ongoing on libnabo?

HannesSommer commented 6 years ago

@pomerlef , I'm note sure, yet. It might be an old (solved) problem preserved on the system.

@bishesh , could you please wipe the folder ~/.cmake/packages/libnabo/ and try building libpointmatcher again? (it should now find the install directory of libnabo)

And if that works, and you have some extra time to help us improving the code: to execute cmake . in libnabo's build folder and try libpointmatcher again (also starting with a cmake .).

bishesh commented 6 years ago

Thanks. I was wondering how libpointmatcher cmake automatically found the libnabo path as build folder; didn't realize that it saves this info in ~/.cmake/packages ! Removing that and setting libnabo path to LIBNABO_INSTALL_DIR/share/libnabo/cmake worked.

About rebuilding libnabo: I had just built libnabo yesterday after using the changed cmakelists file as from here. I can rebuild it, but I am not sure if it would change anything because I would be repeating the exact same steps I did yesterday, right ? I didn't understand exactly what you want to check. But I'd be happy to try if I understand properly what we are trying here.

HannesSommer commented 6 years ago

Thanks for trying and reporting!

I didn't forget about you building nabo yesterday ;). The difference is that you've deleted nabo from the cmake user registry in between (~/.cmake/..). If you try once more we learn whether the problem was from an old entry or whether libnabo is still providing bad ones. They are generated in the cmake config time, I'm not mistaken. It is important that you explicitly call cmake first for libnabo and then for libpointmatcher.

bishesh commented 6 years ago

Yes, libnabo still generates the wrong path that gets picked up by libpointmatcher from ~/.cmake/..

I deleted the build folders, install folders and ~/.cmake/ directories. Starting again from libnabo, which installs fine, the same problem that I reported in this issue comes. The problem is with the variable "libnabo_DIR" which gets set to the libnabo build folder by default. Once I manually change it to the cmake directory in the installed folder, things are fine.

HannesSommer commented 6 years ago

Okay, then we have to fix that. Big thanks for testing and reporting!

Technically it is fine that it finds the build space, because it is supposed to work without install. The issue is with the target then, as the actual error indicates.
