Question

I get the following error.

I thought that this a not properly closed } in frontend.h. Therefore I checked all brackets } in frontend.h with vi and syntax on but they are ok. I am lost and I don’t know where to look at. Please let me know, if you need more information.

The corresponding place in frontend.h is:

Answer 1

You have a conflict with the symbol SYS_DAB. You're defining this as a macro with value 0 on the command line (-DSYS_DAB=0), so when the compiler gets to the enum definition for fe_delivery_system it sees 0 where it should see SYS_DAB.

It's likely that this symbol is being used for two different purposes, so you will probably need to rename one of them - whichever one is used least you could rename to e.g. SYS_DAB_, or something equally creative.
