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:

312 enum fe_pilot {
313 PILOT_ON,
314 PILOT_OFF,
315 PILOT_AUTO,
316 };
317
318 enum fe_rolloff {
319 ROLLOFF_35, /* Implied value in DVB-S, default for DVB-S2 */
320 ROLLOFF_20,
321 ROLLOFF_25,
322 ROLLOFF_AUTO,
323 };
324
325 enum fe_delivery_system {

357 };
358
359 enum atscmh_sccc_code_mode {
360 ATSCMH_SCCC_CODE_HLF = 0,

Here is the output of the

option:

Answer

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.
