Hi All!

After trying the debian packaged Build of Widelands (which is 19) I was very disappointed whith a pointer speed of 0.3 FPS (which was not solveable via configuration). Some folks recommended to build an earlier version which should not be OpenGL-dependend especially Build 18. I tried 10 times or the like until i got all the libs necessary only to end compile.sh with a "was terminated" message after some minor faults and 98% compiled...

But what really annoys me - is that it's almost the same with build 17 as follows:

I do not suppose that all available builds have syntax errors the like, but I'm not that deep into to correct this myself, any ideas?

bash output:

Put ``` before and after a block of code to format it properly.

Well build17 was released in april 2012. I gues it would be pretty hard to get this to compile on modern compilers/build environments, as headers and dependencies especially from our third party packages most probably have changed much since then. I think I remember even @Nordfriese had difficuties getting an old buiold to compile properly today.
I am not sure whether b19 would still compile.

Moin DanRasp and welcome to the forum face-smile.png

It is true that libraries and compilers change so rapidly that code often fails to compile with a compiler toolchain that is a few years newer than the code itself, so b17 would be hard to get working already.

After trying the debian packaged Build of Widelands (which is 19)

(which is very outdated as well, the current version is 21)

I was very disappointed whith a pointer speed of 0.3 FPS (which was not solveable via configuration).

In build21, there's a new option whether or not to use SDL mouse cursor. I would recommend that you get build21 and try out whether toggling this option solves the problem face-smile.png

Try this branch: https://github.com/widelands/widelands/tree/build17

I compiled it like that with Ubuntu 18.04.

today i tried build 21, result:

whatching cpu load i guess it compiled several things in parallel, i hope one can prevent this saving memory...

you might try to invoke compile.sh with the -j option specifiying the processorcores to be used.

Thanks! meanwhile found out myself too...

so i lowered the memory split and set -j 1 now running, past the point it stopped yesterday - interesting fact: codecheck looks differently now, with checksums shown
