FOSS gamedev and creative worlds

This is an old laptop and anything more recent than .3.1 slows down to a crawl.
3.1 used to work fine, but I did something wrong trying other versions and now, I can't get back to 3.1 working.

i am on Ubuntu 12.04
installed Minetest using synaptic manager
some clue to the crash:

"minetest crashed with SIGSEGV in vtable for irr::core::irrAllocator......"

"executing non-writable VMA/usr/games/minetest
reading unknown VMA"

suggestions?

Try to move/rename your ~/.minetest directory to reset all settings.
Move world to new dir if necessary.

I tried to delete all minetest related files and directories and reinstall, but obviously, I missed some.

I first completely removed the package with synaptic, then did a search for "minetest" and removed:
/usr/share/app-install/desktop/minetest
/usr/share/app-install/icons/minetest
/var/cache/apt/archives/minetest..

Can you suggest where else I go look for other minetest related stuff?

Thanks

Try compiling it yourself:


This downloads, compiles and runs Minetest. Just open a terminal and paste the whole code block (it'll do the commands in the right order just fine).

Calinou: so far, so good, if slow.

Thanks a lot

On a second try, it crashes again.

Here is some terminal log info, can you make sense of it:

You already had a directory named "minetest" in your home directory, the game didn't download and compile. Rename it then try again. ;)

I don't know where it was hiding, because I did a system wide search for minetest and found nothing before using your terminal script. I will look further when I get back to that computer.

Thank you for responding.

Go into you file manager, and tell it to quit hiding files and directories from you.

Also, the directory is called ".minetest", if that helps.

You are right, Ogb, I now know to do that and it is saving me a lot of time.

I just need another tip to give myself quick permission to delete or edit system files without the painfully slow "sudo rm" command in terminal. (I am not more linux savy than the minimum to use Ubuntu)

Giving yourself permission to edit system-critical files is bad for security.
If you do that, then any program you run is capable of edit such files (what would happen if you allowed a trojan to edit/access such files?)

You shouldn't remove system files unless you know what you're doing. :P

and I shouldn't play minetest until it is a stable released game ?

seriously: all I wanted to do the other day, was remove all minetest files and folders (some had been left even after "complete package removal") to do a clean new installation. I failed anyway because I had missed the hidden files. I'll try again when I get back to that laptop in a few days.

removes the Minetest package, including configuration files and user data (this includes your worlds).

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

sudo apt-get purge minetest

Thanks a lot, Calinou
