Compilation problems on windows about boundary-first-flattening HOT 7 CLOSED

Linking against BLAS on windows is a bit of a pain, but I remember using this Win64 version of OpenBlas: https://sourceforge.net/projects/openblas/files/v0.2.19/

In particular, I included the libopenblas.dll.a static library in my visual studio project. I'll document the windows build process properly in the next release.

Hi, I tried to compile the project with Win64. When I started to run it, I got the error:

The code execution cannot proceed because nanogui.dll was not found.

Then I copied the nanogui.dll under the binaries\windows to my build directory, but I got the error:

The application was unable to start correctly (0xc000007b).

Is this because I builded it with Win64? I compiled with Win32 before and it worked with no problem.

@JinfanYang I'm not really sure, I haven't tried compiling with Win64. Let me know if you are able to figure it out!

I think you can link nanogui statically. When I have the time to work on it again I will try to document the windows build and possibly improve on the CMake files if neccessary.

Hello, first of, really nice project, the windows binary works great. But now I'd like to dig deeper and built it on my machine (windows) to experiment a little bit. I would probably not even need the ui later on, but I think it is a good starting point to run the whole program.

I have tried to build it under windows in 32 and 64bit with VisualStudio 2017 and CMake 3.13.2

• 64bit windows: after building suitesparse, adding filepaths to the path environment, adding libopenblas.dll.a (from openBlas in the second comment) it was compiling, but upon running I encountered the same issue as JinfanYang (which could be a 32bit/64 bit mismatch?)
• 32bit windows: here suitesparse I get a warning about "A library with LAPACK API not found."
  for 64bit i used HUNTER_ENABLED as mentioned in the suitesparse-metis-for-windows github, so it is available, but under 32 bit "[hunter ** FATAL ERROR **] Broken package: LAPACK on MSVC is only available on WIN64"
  if I ignore this, generate suitesparse, and do the same as with the 64bit version, I end up with LINK errors

I am also not sure what you mean with "On Windows, create a Visual Studio project with Cmake after running the first three instructions." I built it with cmake-gui and then later opened the generated bff.sln with VS2017.

I think the problems stem from LAPACK on my machine but it is a little bit overwhelming for me.
I'd really like to try out the flattening with some of my own meshes that currently can't be loaded (ply format with vertex colors).

Sorry I a beginner when it comes to compiling C++ libraries under windows etc, so my question is, maybe you would be so kind as to provide a more complete (as in starting from zero) step by step guide on how to build it / run it on Windows under VS2017.

Hi, I've included an openblas/lapack dependency in the deps folder specifically for Windows. The windows binary in the project is built under win32. There's also a separate command line app now in the binary folder.

thanks alot! I was able to build and run ( 32bit and 64bit) the new 1.1 version.
