Hi, I have set up a build on Windows, following your guides. LO is built correctly without errors and can be invoked from instdir. But I am still confused about the LODE set up. To build LO on windows you have to install Visual Studio with several options about C++ and .NET Framework. To build you have to set up cygwin. You can use VS as an IDE. But this is not for building, only as an extended text editor which is providing syntax highlightning and text expansion and so on. But why is VS needed then for the build process (except .NET Framework)? Since g++ is used for compiling, why are some parts of MVCS are needed? LO has some dependencies on .NET Framework. Why is not Mono used which is crossplatform and also open source ? Before I start digging into the code I want to understand some dependencies, the build process and other more common subjects about the project. Joachim
