Dear Windows users,
The latest version of MinGW has made some changes in the pthread library, breaking the compatibility with Bocop. Until this issue is fixed, we provide an archive of a compatible MinGW installation on the Download page. All you have to do is to extract the archive to a location without spaces in its name (for instance C:, but NOT C:Program Files).
We are sorry for the inconvenience, and are working on a solution to this issue.
The Bocop team
