Hi folks, we are testing the Boost.Test-Framework (installed with GetIt-Package Boost). We use C++ Builder 10.4.1 with Boost 1.70.0. We have created a new C++ Console-Application (with VCL enabled). Under Project->Options we have set '_TCHAR as char', because Boost.Test seems to need this mapping. It is not working with ' _TCHAR as wchar_t' The application main-entry-function is imported via #include . The application then is run with the params : --log_level=all --report_level=detailed --build_info=true The console-output seems to be fuzzy : 1. Why is the platform win32? We use target-platform win64 and have installed boost 64bit via getit... 2. Paths are outputted with '\' and '/' 3. The fatal-error is correct but the consoleoutput 'St9exception' seems not correctly interpreted (charset ?) Are we doing something wrong or do you have some tipps regarding this ? Thx a lot. This is the console-output : [cid:image001.png@01D71B23.032439B0] Kind regards, Michael Morelli
