cannot build from source on Ubuntu 12.04 about libpointmatcher HOT 10 CLOSED

I suspect that your CMake is not pointing to libnabo or something related. Did you follow this:
https://github.com/ethz-asl/libpointmatcher/blob/master/doc/Compilation.md

If it doesn't work, could you post your CMakeCache.txt?

from libpointmatcher.

Libpoint matcher has to compile with openmp. @pomerlef you need to add the openmp flag to pointmatcher's cmakelist.

from libpointmatcher.

@pomerlef Preferably copy this: https://github.com/ethz-asl/libnabo/blob/master/CMakeLists.txt#L51

from libpointmatcher.

@simonlynen Any ways to have those flags optional? There are quite some code relying on libnabo...

from libpointmatcher.

If the flag is required, shouldn't it be provided in the link flags for nabo through the generated libnaboConfig.cmake?

from libpointmatcher.

@pomerlef it is optional https://github.com/ethz-asl/libnabo/blob/master/CMakeLists.txt#L51 if the user has openmp it is activated.
@stephanemagnenat yes I will try to export that properly.

from libpointmatcher.

@stephanemagnenat I will investigate why my previous approach: https://github.com/ethz-asl/libnabo/blob/master/libnaboConfig.cmake.in#L16 doesn't seem to work

from libpointmatcher.

Thanks @simonlynen
Adding this: https://github.com/ethz-asl/libnabo/blob/master/CMakeLists.txt#L51 to the libpointmatcher CMakeLists.txt file solves the issue.
Once you resolve it permanently, I can try this all again.

from libpointmatcher.

This should be fix with the commit 790f2b5

@pmolina7 Could you update you libnabo repository, clean your build files and rebuild libnabo and libpointmatcher? Everything should work now.

from libpointmatcher.

Thank you @pomerlef - it all builds correctly now :)
