Strange error in Dosbox

I just swapped OS, it seems to me that the speed issue is existing already from version 180209 ! So seems to be not a fresh issue. If somebody has still this not yet updated system version, he can perhaps confirm.

@voljega
@lmerckx
Also to note, if it can help. I have not all versions but see a notable increase of size between 2017 and 2018 :

OS 170417 Dosbox size 2977700

OS 180209 Dosbox size 5048136

OS 180330 Dosbox size 5111180

For the moment I copied back the version from 170417 to /usr/bin, and again perfect.

@dragu nice to know ! well maybe @lmerckx will have an idea (and 14 569 notifications )

@voljega
Also something new about the MOUNT C "/usr/share/dosbox" story.
After copy of dosbox 2017 version, this always exist in the actual OS 180330, seems to be a configuration issue.

[lmerckx]

@Dragu @voljega For the moment, not too many notifications !
But sorry for the inconveniences.

The /usr/share/dosbox usage is clearly new to virtual keyboard. The increase of size is strange indeed: new modifications due to b*mp and virtual keyboard modification can't explain this size.

As voljega said before, can be due to a change in compilation directives !?

I will check tonight. But, on my RPI2, I detected no lag ... what are your platforms ?

[Dragu]

@lmerckx
Dont work in the nights !
We have time and also a job to pay for the playing toys. Anyway, for the moment, I am fine with older version.
In my case it is the PI3, but are there differences also in dosbox in PI versions ?
And dont worry.

[voljega]

@lmerckx RPI3 for me too

[Dragu]

@lmerckx
@voljega
Could this be a possible explication for the volume size increase, that the 2018 build is the 64-bit version and not the 32 ?

[lmerckx]

@Dragu @voljega
Back home ...

I've just tested my DosBox RPI2 (updated to 18.03.30) and I confirm: I have no lag problem on games Wolfenstein 3D, Epic Pinball, Ultima 7.
The size of my dosbox is 5046488.

Can you send a support archive ?

Edit: Now, I can reproduce the /usr/share/dosbox bug ! I've never tested without dosbox.bat, in fact.
I look for a correction.
Still no idea for lags.

[lmerckx]

@Dragu Mine is still 32 bits.
Here is the result of the "file dosbox" command, launched from another Linux workstation:
dosbox: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 4.4.0, stripped

[voljega]

@lmerckx doesn't work in recalbox for me : # file dosbox -sh: file: command not found

tried Epic Pinball, lags horribly too :s

@lmerckx do you have a RPI3 ?

[lmerckx]

@voljega Yes, I had to transfered my dosbox exec to another Linux workstation to get "file" command.
I have a RPI2.

Do you also launch games with autoexec or with a dosbox.bat script ?

[lmerckx]

@dragu So, I think I have solved the "/usr/share/dosbox" problem:
When there is no dosbox.bat file in directory, DosBox scan other parameters to find a valid file to execute or directory to mount. When it find the share directory, it stops and go on with it.
It explains why I had no problem. I always use the dosbox.bat file.

So, the solution was to put the initialization of the virtual keyboard before the autoexec startup.

But, I'm curious, how do you configure your autoexec ?
Do you need to specify the mount and exit in it ?
Do you have an example ?

@lmerckx said in Strange error in Dosbox:

s**t I f you don't have a rpi3, it's not gonna be easy to find the issue ...

Do you also launch games with autoexec or with a dosbox.bat script ?

I always use a dosbox.bat with all necessary instructions in it (mount for instance but no need for exit), I keep no command at all in dosbox.cfg (I always have one too)
If you need, I can give you my dosbox.bat and dosbox.cfg for Epic Pinball

@lmerckx said in Strange error in Dosbox:

Yes, I had to transfered my dosbox exec to another Linux workstation to get "file" command.

figured as much, but I don't have any linux at home other than my recalbox ...

@lmerckx
In general I have always an dosbox.bat file to start games, and mostly the mount operations I make at the end of dosbox.cfg. But this is just personal choice and no issue.
I found the story with the VK at testing a game. Because, if you start with dosbox.bat and have an error, you will never see it Screen erase instantly.
I for this reason sometimes start a game with no dosbox.bat, for debugging.
Concerning the speed lag, it is in relation important 1/2 as before if not less.
What is surprising that you have with the PI2 no problems, but we with PI3 have.
So, I think solution between both build.

[Dragu]

@lmerckx
I have another idea. Would it be possible to upload somewhere your version of PI2, to test with PI3 ?

[lmerckx]

@Dragu Good idea. The link is here: https://www.proximuscloud.be/web/app/share/invite/HLQ1C8rABR
If it doesn't work with it ... can you send me your configuration file. Perhaps, is it a change I made which still allow to get good performance.

[Dragu]

@lmerckx
I think it was not so brillant as idea, as the file is not executable under PI3. I dont know the reason and expected downward compatibility, what is not the case. So, this will unfortunately not help us.

[lmerckx]

@Dragu Sh... Can you send me your confiuration file anyway ?

[voljega]

keeps getting stranger and stranger !
