Error Linking Surfelmeshing Binary

[captain-pool]

Hey @puzzlepaint ,
I have been trying to build your project, but the build is failing every single time due to some Linker Failure. I'm not sure how to debug it, can you please help out?
I'm on Nvidia Docker, so CUDA version, OS and Qt version is not an issue. But I still keep on failing. I'm down with any configuration that works. Here's the Dockerfile

These are the configurations that I tried:

1. **Ubuntu 16.04 with CUDA 10.1 and Qt 5.9.1 **: Failed due to linker error (Something similar to the bottom, but it was 55 inplace of 52)
2. Ubuntu 14.04 with CUDA 8.0 and Qt 5.2.1: QOpenGLWidget not found
3. Ubuntu 14.04 with CUDA 8.0 and Qt5.4.1: Was having an issue similar to error: ‘AA_DontCheckOpenGLContextThreadAffinity’ is not a member of ‘Qt’ #10
4. Ubuntu 14.04 with CUDA 8.0 at Qt 5.10.1 (as mentioned in error: ‘AA_DontCheckOpenGLContextThreadAffinity’ is not a member of ‘Qt’ #10): Here's the log

I googled everywhere, but couldn't find something that helps. 😞

Hi, looking at #10 again and at the Readme, it appears that the Readme specifies a wrong "known working" version for Qt. Sorry for that, I will remove this.

It should work with the newer Qt versions however. Looking over the linker errors that you got, I think that those come from Qt. None of the missing symbols seems like something that is directly used in SurfelMeshing, and all seem to originate from Qt source files. I think that those could be likely fixed by either:

• Linking in the missing libraries manually (by adding them in SurfelMeshing's CMakeLists.txt). Googling for the names of the missing symbols should reveal in which library they are supposed to be. For example, the ucnv_ ones might be in libicuuc.so.
• If you compiled Qt yourself, change the way in which these libraries are compiled in, I think there should be configuration options for that in the Qt build configuration.
