ARM Keil error #17 expected a “]”

Demetris Tziambazis

I am trying to build a program on Keil µVision v.5.12.

The errors seems to be only "one" (expecting a ]) .

Rebuild target 'Target 1'

What did i do wrong? (am i forgeting anything setting up my keil project?, perhaps a .h? or is the [0 ... dimension] declaring my matrices? )

    Sorry but I am new with all this and I try to learn as fast as I can.

    The ranger [ 0 ... Dim ] is not acceptable obviously by the compiler.
    I initialized my matrices otherwise and now that error disappeared.

    But now I get this....

    Add the library, object file, or source file that contains the implementation (in source code form or in already compiled binary form) of fix16_mul() etc to your project.
