qhull run-time error when using CreateFromPointCloudAlphaShape #1364

Closed HSarham closed 4 years ago

HSarham commented 4 years ago

Describtion I get a runtime error when running CreateFromPointCloudAlphaShape:

QH6248 qh_lib_check: Incorrect qhull library called. Caller uses reentrant Qhull while library is non-reentrant QH6249 qh_lib_check: Incorrect qhull library called. Size of qhT for caller is 8232, but for library is 2896. QH6255 qh_lib_check: Cannot continue. Library 'qhull 7.2.0 (2015.2 2016/01/18)' uses a dynamic qhT via qh_QHpointer (e.g., qhull_p.so)

Environment:

Hm, sounds weird. Could you try to build it with gcc instead of clang.

Here is what I found: Compiler of Open3D | Compiler of my own program | Result clang | clang | run-time error above gcc | clang | run-time error above gcc | gcc | different run-time error (1) clang | gcc | Linking error (2)

I don't know maybe it is my program however I think it is worth looking into. (I am using OpenMP both in my program and for Open3D if it is any help)

HSarham commented 4 years ago

I found the problem. On Ubuntu 18.04 I had installed libpcl which depends on libqhull-dev. There is a conflict between the qhull compiled in Open3D and the default one installed on the system. The reason is that libpcl was also used in my project. I removed the libpcl from my project and now things seem to be fine. On the other hand, I tried to remove the BUILD_QHULL cmake option so that Open3D compiles with the default system libqhull but it gives a hard-coded error which I think could be fixed in the future versions of Open3D.

KunikaValecha commented 4 years ago

Have you got this resolved ?

NicoBux commented 4 years ago

I'm having the same error, unsure if it is caused by the same issue as HSarham.
