linux 64bit binary?

[Handoko]

Any luck of generating Linux Player?

I tried to compile it myself using Free Pascal 2.6.2, but failed with libc library. I'm a Ubuntu 64-bit user, it would be great if I can create native Linux games. I've tried Ats ZzDC but it doesn't run well on 3.1b.

[Ats]

Here's the compiled 3.1b player for linux (32bits), sent from my dropbox/phone. I'm not on my computer for a week so I can't help you much. Tell me if it works.

Edit: All right... I can't upload files to the forum from my phone. So here's the dropbox link: [sorry, wrong link... See my next post]

[Handoko]

Tested, unfortunately not working.

I renamed the downloaded file to "Player_linux.bin", started ZGameEditor 3.1b using WINE and opened a test project. Clicked "Android: build zzdc.dat file" and "Build Linux x86 binary". I set the result file as "Allow execute file as program", but an error message show up if I try to open it: "The file is of unkown type".

I found something strange:
- The file download from Dropbox is zzdc.pac
- The file size is only 41 KB, while the previous ZzDC is 217 KB

Note:
Sometimes the old ZzDC 3.0.0 can work when using ZGameEditor 3.1b. But in many cases, it just shows up a message asking user to choose screen resolution and it quit immediately if we choose any of the option.

Oops sorry, I didn't pay attention. I hate touchscreens...
So here's the link to the good file: https://www.dropbox.com/s/3b086kgyolncp ... _linux.bin

[Handoko]

Awesome, it works. Now the fun begins.

Thank you Ats and the creator of this software.

Nice! Great to see an updated Linux binary! Will be using this for sure, thanks for your work!

[Dragon]

Ok I've finished the instllation from sdl1.2 now the precompiled version from Ats a few posts ago works by me. But the compiler fails with the same mistake as before.

And thanks Ats for an actually compiled version.

[Imerion]

I finally came long enough to try running my game in Linux using this binary.
All I get is this message though : "OpenGL could not be loaded".
How come? OpenGL works fine in all other programs, including a bunch of modern games. I run Xubuntu 14.04 and have an Intel HD4400 graphics card with the latest drivers and mesa 10.1.

[VilleK]

It might be a 32/64-bit problem. The ZGE Linux runtime currently only supports 32-bit.

Make sure you have a 32-bit OpenGL driver named libGL.so on your system.

[Imerion]

Ah, that's right. For some reason I thought this was a 64-bit binary. But if it isn't, then that is the problem. I use a 64 bit system. I'll try it on my other computer instead. Thanks!

Anyone who has the ability to compile a new Linux binary for the latest beta?

Games exported with the Linux binary found here doesn't seem to work.

[Ats]

I'm still stuck with Android 64, so I decided to install linux x86 on an old computer in order to produce a new bin for Linux with the latest ZGE sources.
Here's my updated script with some side notes:

• libsdl2-dev does not work so you need to install the old one
• ppc386 doesn't seem to search for the libs inside the folders, I had to add them manually with several -Fu
• Same as folders, you got to create them manually. Don't know why...

Code: Select all

sudo apt-get update
sudo apt-get install fp-compiler subversion libsdl1.2-dev
svn checkout http://svn.freepascal.org/svn/fpc/trunk fpc
cd fpc
sudo make all
sudo make install
cd ..
svn checkout https://github.com/VilleKrumlinde/zgameeditor.git zge-src
cd zge-src/trunk

cd Build
mv ZzDC Player_linux.bin

Attached is the new Player_linux.bin

But I'm still struggling to launch the produced ZGE file. Here's the problems:

Permission denied
chmod 755 your_file_name

error while loading shared libraries: libSDL-1.2.so.0: cannot open shared object file
sudo apt-get install libsdl-image1.2:i386

OpenGL could not be loaded
I tried several things listed here and elsewhere but can't get past that. I'm on a linux 64 computer right now, I'll test on the x86 one when I'll get back home.

EDIT: Ok, it's working perfectly on linux x86

Hi VilleK, I'm compiling ZGE for linux32, which I was able to compile several times already last year, or maybe two years ago.
But this time around, I get this new error:

[Ats]

So I replaced line 337 of ZPlatform_SDL.inc

Code: Select all

procedure ClipAndCopy(Source : PSoundMixUnit; Dest : PSmallInt; FrameCount : integer);

per

Code: Select all

procedure ClipAndCopy(Source : PSoundMixUnit; Dest : PSmallInt; SampleCount : integer);

as it was in 2016.

And it's compiling perfectly
I was planning on making a GitHub PR, but I got that message when starting editing the file, so I'll let you change it:

We’ve detected the file encoding as ISO-8859-1. When you commit changes we will transcode it to UTF-8.

[VilleK]

Thanks, the error is actually that I forgot to also update the variable name in the loop inside the function. Fixed now!
