Marco Ca.: we will be asked in the near future if we want to keep or drop Windows.

Discussion about Windows support

A long discussion followed, which I try to summarize here.

The main reasons to build our software on Windows were (not in order of relevance):

  • non-GNU compiler (different/more warnings)
  • better development/debug environment
  • possibility of running offline on laptops
  • different operating system (limit the possibility of using non-portable libraries)

The first three points are already addressed without the need of Windows

  • non-GNU compiler: we are using the Intel compiler (even if there are some licensing issues that should be addressed) and Coverity
  • development/debug environment: nowadays we almost do not use Visual Studio and Eclipse reduces even more the its need
  • running on laptops: we can use CERNVM
