2017.1.2 amend fix.dat problem

[SVW]

Hi folks,
2017.1.2 works great, BUT: I can't amend the fix.dat file. Unzipped fix.dat.gz with 7zip, amended the waypoints with Notepad++ (code UTF-8 without BOM), rezipped, replaced the old fix.dat.gz by the new one. FG loads and initializes navdata at startup, but the map won't show any fixes at all
Any ideas? Thanks for help in advance!
Greetings, svw

EDIT:
The coding must be ANSI, then it works fine. Sorry to bother you.
cheers

Hi SVW,

What Windows calls ANSI... not sure if all fixes follow this, but at least the copyright sign at the top of the file is in ISO-8859-1 (aka latin1).

Taking the opportunity to tell you that in FG 2017.2.0, there is an easier and cleaner way(*) to add missing fixes (or even move misplaced existing fixes): see this message. And the same works for nav.dat.gz entries. It is the logical extension of the previously existing NavData/apt feature for airports.

The only thing is: please don't do this only privately: by submitting your corrections to the X-Plane scenery gateway (if not already there), you ensure that one day they will benefit everyone when FG updates these files (this is not directed at you personally, just a general remark!).

(*) Easier because you don't even have to compress the files (though it is possible), and can call them the way you want, as long as they end in .dat or .dat.gz. Just put them in a NavData/fix folder inside a scenery directory (thus, NavData should be a top-level directory inside one of your scenery paths).
Cleaner because you don't have to modify FG's files, you can easily disable your changes/reenable them, and when FG upgrades the files or when you reinstall it for whatever reason, your changes won't be lost.

Here are my files for LOWI and MHTG:

Note: some fix names containing X or Y are slightly different from the real ones, otherwise FG wouldn't show them (I believe this is due to an intentional filtering in order not to clutter the map too much; probably this should be improved some day to depend on the zoom level...).

Merci Florent! J'espère à bientot!

Ja, ja, hoffentlich!

Thats no English video, but I'm sure that you know what to do with the nav.dat.gz file.

[rominet]

Glad to hear it works for you, but in FG 2017.2 and later, there is a cleaner way to do that, as mentioned in my message above. Basically, you can put *.dat or *.dat.gz files in NavData/fix and NavData/nav (as well as NavaData/apt) inside any scenery directory. You may want to create a scenery directory just to contain a NavData subdirectory for this kind of changes. FG will find the .dat and .dat.gz files at startup and merge them in RAM with the canonical ones in $FG_ROOT. This avoids modifiying contents under $FG_ROOT and allows enabling or disabling your changes by simply adding or removing the corresponding scenery path (either with --fg-scenery on the fgfs command-line, or with the corresponding interface in your launcher, if you use one).

[RenanMsV]

Yeah I know, instead replace your apt dat just add it as a custom scenery. I'm just giving you a file with all fix in the world. Thanks
