Many thanks for the fast response.
This solves the problem (- somehow)
I changed the compiler command from
$compiler $options $includes -c $file -o $object
into
$compiler $options $includes -c e:/my_projects/hello/$file -o $object
This works!
Unfortunately this is not very elegant as I need to change the setting for each new project I would like to compile.
Isn't there a macro like "$projectpath" that contains the path to the project??
I haven't seen such a macro neither in the macro list (under advanced settings) nor in the C::B docu.
Are there other options to use an absolute path for the compiler?
