Hello Thomas,
The error you have described typically indicates that a DLL could not be loaded
(in this case libgcc and libstdc++). This can be easily resolved by adding the
directory containing these to the PATH variable prior to starting the program:
set PATH=C:\MinGW64\bin;C:\MinGW64\x86_64-w64-mingw32\lib;%PATH%
Dependency Walker [1] is quite useful for diagnosing these types of problems.
Regards,
