Troubles compiling for windows

[fire]

1. spdlog is missing
2. openvdb is missing
3. boost is missing

Looking into this.

[fire]

Newer instructions that are failing

1. use msys
2. pacman -S mingw-w64-x86_64-boost mingw-w64-x86_64-openvdb mingw-w64-x86_64-spdlog cmake ninja
3. git clone https://github.com/SarahWeiii/CoACD.git
4. cd CoACD
5. mkdir -p build
6. cd build
7. cmake .. -GNinja

[fire]

Some errors:

src/btConvexHull/btAlignedAllocator.cpp:71:31: error: cast from 'char*' to 'long unsigned int' loses precision [-fpermissive]
   71 |         offset = (alignment - (unsigned long)(real + sizeof(void*))) & (alignment - 1);

This is sufficiently difficult that making release builds for windows might be a good idea.

Hi thank you for the suggestions. Our code was mainly tested on Linux, have you tried using WSL to run the code on Windows?

i'm sure it compiles fine on linux but a native windows build would be more than welcome for this fantastic library

[fire]

I am unable to compile for windows.

[yetigit]

I am unable to compile for windows.

@fire please use my fork https://github.com/yetigit/CoACD and checkout to master to build on windows.

git clone --recursive https://github.com/yetigit/CoACD.git
git fetch origin master
git checkout master

and use vcpkg with cmake.

example of using the app :
coacdapp.exe -i chair.obj -o chairout.obj -np -mn 10 -t 0.4 -c 4

the parameter -np is needed to speed things up if you are sure you have a watertight manifold mesh
the new parameter -c (max number of convex hulls) is super useful.

The problem we had here on windows :

• is the namespace pollution. there was a dozen of using namespace std in broad scope headers (this was the biggest problem and I had to go in there and manually prepend std:: to everything for hours).
• couple of incorrect includes
• dependencies not referenced in the cmake file
• unneeded instructions in the cmake file

@SarahWeiii i am not familiar with collaborating using forks and I have some other work to do but do consider the changes I made on my fork, on master https://github.com/yetigit/CoACD and maybe let's try to merge it later, cheerios

[fire]

vcpkg install openvdb:x64-windows
git clone --recursive https://github.com/yetigit/CoACD.git
cd CoACD
git fetch origin master
git checkout master
mkdir build
cd build
$env:CMAKE_TOOLCHAIN_FILE="C:\Users\ernes\scoop\apps\vcpkg\current\scripts\buildsystems\vcpkg.cmake"
cmake .. -G"Visual Studio 17 2022" -DCMAKE_BUILD_TYPE=Release
.\CoACD.sln and build the coacdapp

Work in progress

Need to force 64bit OpenVDB

coacd_RelWithDebInfo.zip

Estimated took an hour to fix the vcpkg problems.

[SarahWeiii]

Thank you @fire @yetigit for the effort of compiling CoACD on Windows! @yetigit you could simply send a pull request to me and I can merge the code into the main branch.

Hi everyone,
I've been struggeling for couple of days now to try and run coacd on windows with no success.

when I "pip install coacd" the installation is complete but then when I try to import it I get:

Is it possible to run this library on an x86_64 os?

[SarahWeiii]

Our library supports x86_64 os. Have you installed vc redist or visual studio?

[SarahWeiii]

We have updated the pypi package, including all the .dll in the wheel. You could install the latest (0.0.4) and try if it works.

How do I get version 0.0.4? pip install coacd is giving me version 0.0.3
thanks

[SarahWeiii]

You may try pip install coacd --upgrade

[Shayp277]

Hi, reinstalled the coacd and now its the 0.0.4 version.
Guess I tried before the package was updated in the pypi.
Now everything works great!
thank you very much for this awesome library and quick response :)
