It could be possible, that something went wrong. I should creat a new project.
Anyway, i tested the -v option on another pc, with right settings. This option doesn't creat a symbol table, so debug is still not working with -v.
The output file name is "Complexe_rechnung.exe" like the project is called.
Seems the debug is not working with Borland. For simple projects i can still use "printf"
Thanks for helping anyway, guys
