How do I uninstall dragenengine?

[ChekPuk]

I was stupid enough to install dragonengine with sudo, this was really bad idea... How do I uninstall everything? Didn't found how to do it with scons.

[LordOfDragons]

You can uninstall any target individually with scons by appending "-c". So to uninstall you can run one of these commands:

• scons -c install => Remove all install targets and their dependencies
• scons -c install-engine-runtime => Remove all install engine targets which includes the game engine and all modules
• scons -c install-igde-runtime => Remove all install igde targets which includes the igde and editors

If you run scons -h you see all supported targets. Any can be reversed with "-c".

Out of curiosity... what went wrong? I did sudo scons installs before and had no troubles. Depending on what went wrong it could be fixed in the code base.

Oh... Sorry, forget to write in op... Restless night :)

I was installing 1.4 release from source tarball, after successful installation and some poking I decided to remove it. Command 'scons -c install' left headers in /usr/incude and /usr/dragenengine with subfolders. Maybe something else. How to do a complete deinstallation?

Installing something in root not with package manager - is a crime, that's why it was bad idea. It's not safe and it's hard to keep tracking files, upgrading and so on.

Interface and the engine was terribly slow on my laptop on both, Intel and Nvidia, some examples crashed with some weird errors. As I understand - the engine is not ready for casual poking of guy like me. This was a reason not to build or try Dragenengine again.

I see. The source code is set up for developing modules and editors and creating distribution files. It is not intended to be used directly by end users.

Instead to use the game engine (as gamer) or create games (game developer) you do not use the game engine sources, instead you use the distribution packages. This way installing the engine goes through the package manager of your distribution and allows proper uninstalling as well as proper updating. That's the intended way to use the game engine both for players and game developers. In particular that's how casual poking at the game engine is supposed to be done. Building the engine source code is only required for a specific group of people with specific needs.

For this reasons "scons -c" is not going to remove all files. In particular it leaves behind directories. This is how SCons works. You can though easily remove these directories after running "scons -c" like this: rm -rf /usr/{include,lib,share}/{dragengine,deigde} Which are in total 6 directories that can be safely deleted recursively.

Can you also tell me what kind of CPU and GPU you are using? This would allow me to better understand what hardware configurations work or do not work. If you can also provide the logs ( ~/.config/delauncher/logs or ~/.config/deigde/logs ) then I can examine what caused troubles. This helps to improve the game engine.

But script that I should download as a regular gamer/developer will install it in /opt, not a big difference. If it doesn't produce package to install it should run from users folder where it can be easily removed.

The other laptop I tried was with Nvidia 1660ti, don't remember CPU, but acted very similar, slideshow in dstestproject and errors on others. Bad luck. Maybe I should try some other building options, but nah, not interesting.

[LordOfDragons]

You can install into a specific directory by using SCons parameter "prefix=path/to/directory" or using "custom.py" (examples in "dist.custom.py" and "dist.posix.custom.py", copy and adjust). That's what I use for active development. It would be possible to modify the default path in SCons. I'll consider it. That said the "install" target is for engine development and package building using sandboxing (SCons option "--install-sandbox=path/to/sandbox").

The GPU looks fine. You should have no troubles running DSTestProject on it (the least demanding example). If the result is so bad I suspect problems with the OpenGL driver. Please provide the log files mentioned above, then I can tell more. On my Laptop I've got nVidia GPU too so that by itself should not be the problem.

[LordOfDragons]

Wait a moment... I totally forgot. You are compiling from "master" branch, is that right? The master branch is currently in progress of working on a new feature and is not stable right now. If you use the master branch right now you are going to get into troubles. Please use the "stable" branch. It points to the v1.4 release. Stupid me that I did not think of this earlier.

[ChekPuk]

No, I was using 1.4 release. Ok. Tomorrow I give it another try, this time I will write down all errors and logs to help you understand what's happening. In new issue?

As for this issue with complete removal I think that there must be a bit more in readme, or in manual.

[LordOfDragons]

It's certainly not wrong to create a new issue for these errors. Helps others looking for problems if issues are not mingled.

I've adjusted the README. More changes can be made if required.

[ChekPuk]

Oh... Installed install-dragengine-1.4-linux64.sh and install-deigde-1.4-linux64.sh... How do I remove them now? Scons provided -c option, but by installing with scripts I can't really know how to remove them back. This is wrong. I quit.

[LordOfDragons]

The uninstall option I've added for the 1.5 release. You can use them already now by getting the nightly build installers since their uninstallers work also for older installation. To uninstall run the installers with the "--uninstall" option: https://github.com/LordOfDragons/dragengine/releases/tag/nightly .

[LordOfDragons]

I'll close this issue since the information provided in here should be sufficient.

Concerning the running issues please create a new ticket and attach the above mentioned log files.
