I downloaded it for raspberry pi and moved it over to the worlds folder inside the map i want to use. and go to run ./mapserver and i get bash: ./mapserver: No such file or directory

Did you try it with

Code: Select all

chmod 755 ./mapserver

Maybe just a permission issue (executable permission)

Sorry about that. That was a mistake on my side: i thought cross-compiling with go would be easier than in C/C++ :D
Anways, i released version 0.0.2 for windows and linux (32,64 bit x86 and arm)
I tested the linux-arm release in an emulator and it looks good so far (if your map is big though it will be slow initially)

[DoyleChris]

Well i tried the latest version on my RPI and i get the same error. Even by running chmod 755 ./mapserver i still get, chmod: cannot access './mapserver': No such file or directory.

[DoyleChris]

i got it to work had to change mapserver-linux-arm to mapserver

[DoyleChris]

I get this though

Code: Select all

Yay! Another Go tool! Congrats!

Can you try it with the newest release (v0.0.3):
https://github.com/thomasrudin-mt/mapse ... /tag/0.0.3

I changed the database flags to account for the increased delay

[BuckarooBanzay]

Thx, i wanted a simpler, more maintanable solution than the java-bloat i already had :)
Its a fun language with a pretty good learning curve...

I got another error to do with the map.

Java isn't bad if you're prototyping, but if you're deploying on a smallish cloud instance, it's impossible, literally, because you need half a gig of ram to even run. With golang, you can deploy without any of that.

Could be that the mapserver is still locking the sqlite database, and MT really does not like that.

[DoyleChris]

Found out i ran out of space.

The cause was/is a full disk, as the message said :)

database or disk is full

The mapserver opens a read-only connection to the sqlite database to circumvent such things as locking, works good as far as i tested it. That won't be a problem for the next database-connectors (psql to name one).

One exception for the read-only connection is the initial connect though (in which the timestamp-columns are added)

@DoyleChris thx for testing :D let me know if you have other issues

Next item on my list: realtime updates of travelnets, lua-displays and poi's xD

Cant see players on the surface.

Thats on my roadmap, don't worry :)

Planned features:

• POI markers / mod integration
• Player markers and infos (HP, breath, etc)
• Street names / Train stuff

So i moved my minetest server from the sdcard to a external harddrive. The harddrive is NTFS.
i go to run the ./mapserver command and i get this message.

Code: Select all

panic: unexpected end of JSON input

goroutine 1 [running]:
main.main()
        /home/thomas/git/mapserver/server/main.go:43 +0x2ec

I think your mapserver.json got somehow corrupted :(
How does that file look like on your drive?
You could try to replace it with the following snippet or deleting it alltogether (it needs to re-render the whole map though)

How or can I specify a colors.txt file?

I use my lib_materials and lib_ecology mods. lib_materials defines a lot of new grass, dirt, ore, stone, sand and liquid types, that make up the world. lib_ecology adds to this adding plants and trees, and defining biomes.

I do not currently have an updated colors.txt for minetestmapper that accommodates my mods, but nothing here indicates this would be necessary. If this is not the case, which mods, specifically, does this support?

I just released version 0.1.0 with a lot of new features, the custom colors.txt is documented here: https://github.com/thomasrudin-mt/mapse ... /config.md

BuckarooBanzay,

Just wanted to let you know that I have generated values for my mods for colors.txt. The maps look great.

Thanks,
Shad

Good to hear :)
I'm currently working on the postgres implementation.
After that i will move the map for pandorabox to this mapserver.
30 GB of map-data with 4 layers... i wonder how long this will take :D

This release is not backward compatible, sorry...

Important changes:

• Postgres support (experimental)
• More mapobjects (technic anchor/quarry/switching station)
• Realtime train/composition display
• New tile-storage (not backwards-compatible)

Train markers

Is this already operational on your server?
