When trying to debug this Eclipse CDT Project compiled with Mingw-w64 (build-info.txt) and clicked Debug as Local C/C++ Application, the following error is shown:
Reinstalling Mingw-w64 didn't fix the problem. A sample Hello World C++ Project compiles and debugs as expected but for any reason this Project doesn't. Maybe it has to do with the fact that it utilizes the libxl-3.6.2.0 dll from bin64 folder to read an excel file.
Eclipse configuration:
Eclipse Mars.1 (4.5.1)
Debugging became possible just adding the 64 bits dll inside LibXl folder bin64 to the Debug folder (where the generated executable was created). This solution insight came from @smurff1975's comment in the following thread.
