Possible to port GridWars 2
-
Sorry to bump a very old thread, but it appears better to do that than start a new one to give some consistency. I was just wondering how you got this to work @fluffypillow. I understand that it definitely won't work perfectly.
Do you just download the binary from https://github.com/mmatyas/GridWars/releases and execute it or did you also need to compile the source code too? If you needed to do the latter, did you place the binary in the same directory/folder as the compiled source code and run it?
I'm on a rpi 3B but still using jessie.
-
@spud11 at least in my experience with it it would start to run and then quickly crash. I wouldn't consider it playable on its current state on the pi
-
@spud11 If I remember correctly, you have to clone/download the git repo ("Source code" on the releases page is fine too), as that contains the game assets. Then download the binary, place it into this directory and run. Shouldn't need to compile anything, the binary on that page is already compiled for you. But I can take a look tomorrow if it still fails.

@fluffypillow @herb_fargus Thanks for your replies, guys. Must admit I haven't even been able to get it to run at all. I've copied the
gridwars-armhf-rel
file into a folder together with all of the source files. The binary is executable. I've run the binary straight from commandline usingsudo /bin/bash gridwars-armhf-rel
with the resultgridwars-armhf-rel: gridwars-armhf-rel: cannot execute binary file
. -
@spud11 Which folder have you copied into ? Looks like an error related to the filesystem mount options, usually you get this when the filesystem is mounted with the
noexec
option. -
@mitu Seems a bit strange because I haven't used
noexec
option anywhere. All files appear in the/home/pi/RetroPie/roms/gridwars2
folder that I have created and I'm just trying to start the file from commandline. -
@spud11 Have you made the file executable (
chmod +x gridwards-armhf-rel
) ? Note that you should run it via./gridwars-armhf-rel
, not withsudo bash ...
. -
@mitu said in Possible to port GridWars 2:
./gridwars-armhf-rel
Hi mitu. Happy New Year! Yes, I have given it the correct permissions and for good measure used the command you gave. I have also tried
./gridwars-armhf-rel
, but get permission denied. -
Just tried the binary on an up-to-date RetroPie, and it launches fine for me, without sudo or anything. Your errors seem to show filesystem issues as @mitu said; are you trying to run the game from USB or Samba share perhaps? Have you tried a different SD card?
As for the game, due to the GLES lib name changes on Stretch, it hangs on startup with an initialization error, then eventually crashes (patching the binary is not enough). Likely a bug in the engine itself.
-
@spud11 I got the same behavior as @fluffypillow - the program starts, but it's not fully compatible and crashes. But it's not the same error as yours, for sure.

If someone is interested for Windows version.
This link seems to be the only woking oneYou will find download link directly under first picture ;)
-
Up ! Can someone sum up where we are?
Which version did you use ?
I can certainly help going forward with this quest (having GW run on the pi), I'm a CS engineer... -
@toto2000 great! So at the moment on Debian Stretch the game doesn't start up properly, however it used to work (as in, launched) on Jessie (Wheezy?). There are quite a few issues with the engine causing crashes, you may want to run through the code with the debugger to catch them all.
You can get the code and my patches here, and also some build instructions. A prebuilt binary is here, the one that used to launch originally.
-
@toto2000 That would be great. I was unable to get the pre-built binary to work on Jessie (which I'm still on).
-
@fluffypillow Ok, I already managed to recompile completely the compiler itself and maxIDE on my Mac + compile GridWars using the command line + MaxIDE. Next -> recompile all these things in the Pi. I followed your instructions + get your controls.bmx patched file (original did not compile due to a Joycon not found error)
Do you have an idea of what was going wrong? Problems with the OpenGL version?
-
@fluffypillow Which version of the compiler did you use? This one : https://github.com/bmx-ng/bmx-ng/releases/tag/v0.81.3.16.rpi or a more recent one that you recompiled for the pi? On the Mac I used https://github.com/bmx-ng/bmx-ng/releases/tag/v0.99.3.31.macos and was wondering if I could recompile the up to date sources on the Pi, like I did on the Mac... Maybe this would maximize the chances of building a runnable GridWars..?
-
@fluffypillow You have been talking about Opengles, but the REAL OpenGl should be supported on Pi (see
Look at the YT video I linked. Apparently, OpenGL hardware acceleration is still experimental in 2018 and should be turned on from raspi-config... Ok, I'm investigating, and will let you know if I find something interesting...
-
@toto2000 Turning on the OpenGL driver will probably break the other RetroPie emulators, so be aware of that when testing.
-
@mitu Ok. I'll see what's happening then....
-
@mitu The problem is that Gridwars uses the OpenGL driver that requires OpenGL 1.1 minimum. (See this line in gridwars.bmx :
Framework BRL.GLMax2D
If I change this to :
Framework Pub.OpenGLES
That is the framework supported by default by the Pi, then, many things will not compile (such as TImage not recognized etc.)
So, we have to stick with the openGL driver. And if it's not hardware accelerated, then the Mesa OpenGL software implementation is certainly the one being used, that for sure will make the game unplayable.
My goal is to 1) recompile blitzmax tools (not use the old precompiled binary) 2) compile GridWars 3) try with the experimental hardware accelerated driver.I'll keep you informed...
