Funny. Maybe it’s a line ending style problem? Our source files are originally all linux-style line ending, so if you unzip the source package you need to tell it to transform the line endings of text files, either with whatever UI option your zip client has, or on the command line with “unzip -a ….”. Mingw would probably handle any line ending, and maybe msvc2013 was made less picky there as well?

Right, the plugin loader bails out... . So if you want to provide your plugin to users of the binary download of Qt Creator, you need to make sure that you match the Qt version and compiler version of the Qt Creator in the package (that’s why we also added info about the compiler in Qt Creator’s about dialog). We should be clearer about that in the “extending” manual, and possibly mention that in the README as well (since it’s a more prominent place).
