Having trouble compiling panda3d on Windows

Compiling or Editing the Panda Source

I am having trouble compiling Panda3D on Windows 8.1 x64 with Visual Studio 2017.

makepanda\makepanda.bat --everything --installer --no-eigen --msvc-version=14.1 --threads=1 --arch=x86

Do you have the assimp library available in your build environment?

3

Yep. I built it in the thirdparty directory using the panda3d-thirdparty repo.

4

It’s not immediately obvious to me. What happens if you replace that copy of assimp with the ones we provide in the thirdparty packages on the download page?

5

Where in “Thirdparty tools for Windows (32-bit)” is there the assimp folder?

6

You should get the 64-bit one, not the 32-bit one. It should be in panda3d-1.10.0/thirdparty/win-libs-vc14-x64/assimp which you can drop in instead of the one you built using the panda3d-thirdparty repo.

I’m trying to build 32 bit since unfortunately I have to support windows xp.

8

By the way, if you are not using Assimp, you can skip building libp3assimp using --no-assimp. However, you may just run into similar problems with other libraries.

9

Perfect! That was exactly what I needed. Everything else compiled perfectly.

(For the record, Windows XP is still supported by the 64-bit build, as long as you use either Python 2.7 or 3.4, but it makes sense that you might still want to support 32-bit machines as well if you are targeting XP.)
