Linux support

[HunabKu]

Hi all, i make this subject to speak about linux support.

What issues with solutions we have :
- Linux differentiate uppercase and lowercase unlike Windows does. So the generated code is buggued.
Temporary fix : Launch MonoDevelop with MONO_IOMAP=case prefix.
Hypotetic definitive fix : Don't know atm, this issue comes from Mono code.

- Mono don't know ColoredConsoleAppender.
Temporary fix : Replace ColoredConsoleAppender to ConsoleAppender in config/logconfig.xml file.
Hypotetic definitive fix : Make building detect if host os is linux, then modify logconfig.xml file before copying. Maybe DolServer.exe detect if logconfig.xml is host os compatible and change it before launching.

- Linux differentiate uppercase and lowercase unlike Windows does. So the same folder with case differencies is considered as two folders by MonoDevelp when loading solution.
Temporary fix : Replace by AdminCommands/GMCommands/PlayerCommands the other case versions in GameServer/GameServer.csproj file.
Hypotetic definitive fix : Make temporary fix and commit it. This will not affect Windows building !
Commited here, waiting validation.

- File names and lines appear <file unknow>:0 in console/logs when an error occur.
Temporary fix : Launch mono with --debug parameter.
Hypotetic definitive fix : Don't know atm, this issue comes from Mono code.

- Building create 2 folders : debug and Debug.
Temporary fix : Copy debug files on Debug after each building. I personnaly added cp -rf debug/* Debug/ in my DoL launch script.
Hypotetic definitive fix : Found debug occurencies, modify it on the core ans commit it.

- When an Windows gererated serverconfig.xml file exist, server won't to start.
Temporary fix : Remove existing serverconfig.xml and launch DOLConfig.exe to generate another.
Hypotetic definitive fix : I mean make DOLServer.exe detect if host os is linux, then delete existing if needed and launch DOLConfig.exe to generate a serverconfig.xml file is linux compatible.

- Have this error on top DoLServer start :

Code: Select all

Starting GameServer ... please wait a moment! log4net:ERROR XmlHierarchyConfigurator: Cannot find Property [mapping] to set object on [log4net.Appender.ConsoleAppender] log4net:ERROR XmlHierarchyConfigurator: Cannot find Property [mapping] to set object on [log4net.Appender.ConsoleAppender] log4net:ERROR XmlHierarchyConfigurator: Cannot find Property [mapping] to set object on [log4net.Appender.ConsoleAppender] log4net:ERROR XmlHierarchyConfigurator: Cannot find Property [mapping] to set object on [log4net.Appender.ConsoleAppender]

Temporary fix : Comment or Remove <mapping>...</mapping> lines in logconfig.xml.


What issues we have no solution.
- Have this log when i go to NF :

Code: Select all

Search for frontiers/frontiers.mpk:numkeeps failed

Researches : I tried to add a empty numkeeps file to the frontiers.mpk file. The message still occurs. When i try to reload the mpk file on the software, "Range check error" message appears. I think a package checksum is in place and block to add/remove files. I think they are same error on Wndows but don't show. I think so the numkeep file isn't still used because don't block anything in game.
NO FIX

What issues with solutions we have NOT, need help :
- Certains file names and lines appear like <15029c3817b245ffb50e9433f5ade25d>:0 in console/logs when an error occur.

This is all "Build" Problem for Linux...

Except for the serverconfig.xml problem (probably due to line ending in CR/LF instead of LF)

If someone is using Linux as development platform I hope they'll have the skills to work around these glitches easily !

DOL Runtime have no issue that I know of when running with Linux/Mono...

By the way don't forget that you can use symlink on Linux filesystem, (ln -s) this can provide different case file name or directory name leading to the same content.

Great idea, i will test

Sadly not works. The --debug help for certain files:line but not all, with or without symlink :

I tested to build with xbuild directly, not with MonoDevelop but same problem.

New other problem : MySQL problem, only on linux, it works on Windows. Due that, server won't launch.

Solved alone without explanation... Maybe Mariadb update.

[Graveen]

Yop Hunab, can you embedded in the project a DOL.linux.howto file with mandatory software versions (mariadb,etc... Give simply a working one ) and the actual issues ?

Is there a way to know we are running Mono and simply put an if() for StatCounters ?

I will talk about with Leodagan.

research : no solution

[Leodagan]

What is this trouble ?

[HunabKu]

No trouble. Just a messsage. I think numkeeps file used in past for OF or 1st NF because they are no problem in game about keeps.
