Problem to conda-build SOFA

[Namejess]

Hi everyone ! ✌

I try to create a conda package via conda-build in order to be able to deliver SOFA ready, directly uploaded on Anaconda.org

Windows 10.

I have created a recipe folder with a meta.yaml file that looks like this (in sofa/src/ from git clone):

package:
  name: sofa
  version: 22.11.00

source:
  path: ..
  

requirements:
  build:
    - {{ compiler('cxx') }}
    - "cmake"
    - setuptools
    - "boost >=1.65.1"
    - "python >=3.7"
    - "qt >=5.12.9"
    - "Scipy >=1.2.0"
    - "numpy >=1.16.0"
    - "pybind11"

  run:
    - "eigen >=3.2.10"
    - "qt >=5.12.9"
    - "qt-webengine >=5.15"
    - qt-main >=5.15
    - python
    - "boost >=1.65.1"
    

build:
  number: 0
  script: |
    cmake -S . -B build -DCMAKE_INSTALL_PREFIX=$PREFIX -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH:PATH="C:/Qt/5.15.2/msvc2019_64" -DCMAKE_PREFIX_PATH:PATH="C:/CDA CCI/INRIA/sofa/src/Eigen3"

The build comes to the end but my error log looks like this (sorry for the length):

Performing C SOURCE FILE Test CMAKE_HAVE_LIBC_PTHREAD failed with the following output:

Source file was:

}

int main(void)
{
  pthread_t thread;
  pthread_create(&thread, NULL, test_func, NULL);
  pthread_detach(thread);
  pthread_cancel(thread);
  pthread_join(thread, NULL);
  pthread_atfork(NULL, NULL, NULL);
  pthread_exit(NULL);

  return 0;
}

Does anyone have an idea for debugging?

Thanks 🤞

CMake seems to check if pthread is available on the system (CMAKE_HAVE_LIBC_PTHREAD). However, you are on a Windows system, so it should not be available.
Can you give more details on the failing step. What part of the code is calling the check of pthread?

We can close this thread, I'll continue the project directly on Linux.
