Building goGPS java 1.1.0 COMPILATION ERROR :

[jpsitou]

I tried to compile the currently released library with JDK-21 and JDK-23, but I got the following error.
It seems to be a problem with some of the source code, so I would appreciate some advice.
(The error message contained Japanese text, so this is a translation of the Japanese text into English.)

Apologies, it's been 3 years since I worked on this and I must have forgotten to push some changes.
I've fixed the compilation errors, can you try again?

[jpsitou]

Thank you for the information. I tried again, but
RinexNavigation.java:[435,27]
I am getting an error because the RinexNavigationParserGlonass class is undefined.
Could you please advise on how to deal with this?

The following is the content of the error message during packaging:

[ZiglioUK]

You're absolutely right, apologies. I forgot to add the new file (it's still a stub though, no Glonass Rinex parser yet)

[jpsitou]

Thank you for your apology. I understand the situation.
I'd like to ask if there are any plans to add the Glonass Rinex parser in the future.
If there are no plans for that, could you please advise me on possible alternative solutions?

[ZiglioUK]

@jpsitou do you actually need a parser for Glonass Rinex? this library is not currently being maintained but we could always ask ChatGPT to fill the gap...

[jpsitou]

I apologize that I haven't been able to fully understand the details yet, as I haven't successfully compiled and used this library. If possible, I would greatly appreciate guidance on either:

Whether a GLONASS RINEX parser could be added to this library, or

How to resolve potential parser errors when attempting to use this library for RTK positioning with GLONASS RINEX data.

However, if the library is no longer maintained and there are no plans for updates, I will need to consider alternative solutions independently. Thank you for your helpful response.

[ZiglioUK]

@jpsitou what I mean: I've already fixed the compilation problem by providing an empty implementation of the Glonass Parser. If you need to process Glonass observables it would take time by hand (also I'm not using GoGPS these days) but probably it would take no time for AI to do it, so we could look into that

[jpsitou]

Thank you very much. After receiving your message five days ago, I tried downloading and compiling again, but it didn't work. However, after your recent suggestion, I downloaded it again and was able to compile it without any issues.
