Just for the records, "kamailio --cfg-print" should not show any preprocessor directives, it should plain text with the preprocessor directive/conditions evaluated, but its output should help identifying when some preprocessor directive is set to a wrong value or misplaced/missing.
Then, is the last #!endif on the last line without a new line after it? If yes, add a new line after it, the parser might not see it otherwise (although I thought was addressed at some point, it might be only my hope it happened).
Cheers, Daniel

A few quick thoughts on this:
- Preprocessor definitions can begin with either |#!| OR |!!| so you might want to use this as your grep regex (I didn't test this, but i think it would catch both patterns): [#!]!ifn?def|[#!]!endif
- You mention that you have a definitions.cfg file which means that you're using at least one include_file or import_file declaration, and if you're using one, then it's a good chance you're using more than one. Make sure you're considering your entire Kamailio config file. Rather than grepping only kamailio.cfg it might be more helpful to dump the kamailio config to grep: kamailio --cfg-print | grep [#!]!ifn?def|[#!]!endif
- Finally it might be good to consider if you need all of those preprocessor defines and ifdefs. Yes, the default sample config has many of them, but that's a situation where a single file is meant to be able to illustrate a lot of potential use cases. In most real-world situations, you will program the server already knowing what you will/wont need and not need all of those feature flags. Like, either my environment has RTPEngine and I'm going to use it, or it doeesn't. I know this when I write my Kamailio scrip, so either I write the code I need or I don't. It's likely that you can clean these up, resolve your issue, and have the benefit of a cleaner more easier read config as well.

Hello everyone,
I'm having an issue with my Kamailio config where I'm getting the following error:
ERROR: bad config file (0 errors) (parsing code: 0) 0(2) ERROR: <core> [core/ppcfg.c:276]: pp_ifdef_level_error(): different number of preprocessor directives: 1 more #!if[n]def as #!endif
I've gone through the config up and down so many times and can't seem to find the problem. I have a definitions.cfg file where I define all the variables, and I’ve made sure that every #!ifdef WITH_SOMETHING has a corresponding definition. I also ran this command (recommended by GPT):
grep -E '#!ifn?def|#!endif' /usr/local/etc/kamailio/kamailio.cfg
It shows matching numbers of #!ifdef and #!endif, and I’ve checked it manually several times — everything looks fine. Any tips for debuging or finding the problem.
