Out of memory error while compiling

[SuperRiderTH]

I have been using Enigma for a bit and I went to run the game and I got:

cc1plus.exe: out of memory allocating 65536 bytes
mingw32-make.exe[1]: Leaving directory `e:/ENIGMA/enigma-dev/ENIGMAsystem/SHELL'
mingw32-make.exe: *** [Game] Error 2

Is there anyway to fix this?

Holy moses. How big is your game? Or are you just genuinely short on memory? I don't think the JVM's allocation bounds affect ENIGMA's compiler; if they did, it would be possible that your game was just big enough to only cause a memory issue when compiling.

Could you get us the size of the game file, and the memory consumption of each of LateralGM (javaw.exe) and cc1plus? The task manager should list those.

[SuperRiderTH]

The .gm81 is 9.17 MB (9,623,627 bytes) according to windows, and it cant be a problem with memory, I have 12GB of ram.

 I tried to run it again, got the same error, and I watched the Task Manager and I saw cc1plus's memory go up to around 2,000,000 K. java.exe is at 728,900 K while running.

In the run file I added -Xmx1000M -Xms1000M to the command for starting up enigma, the game fails to open otherwise.

Also, I dual boot Windows 7 (64-bit) and Ubuntu 13.04. While I am using Ubuntu and I try to run the game my whole computer becomes non responsive while compiling and never finishes.

Well 2GB is the amount a 32bit program can get. When it hits that ceiling windows will trow an exception (aka crash) when more is asked. The question is why cc1plus does this? And a better question is what the hell is cc1plus? Shouldn't it be g++?

[forthevin]

2 GB is far too much, cc1plus should not use nearly so much memory. It may be the same issue as when compiling Iji.

After trying to run on Windows, could you give us how many lines the file ENIGMAsystem/SHELL/Preprocessor_Environment_Editable/IDE_EDIT_object_functionality.h contains?

[SuperRiderTH]

IDE_EDIT_objectfunctionality.h has 18062 lines.

[Josh @ Dreamland]

This smells like a bug in GCC. Nothing ENIGMA puts in that code should make it bloat to 2GiB. The only other file that might bloat up immensely is IDE_EDIT_objectaccess.h... Even then, though, 20,000 lines is hardly a reason  to require 2GiB of RAM.

Would you be willing to share either of the game file or that folder (Preprocessor_Environment_Editable)? It contains a loose C++ translation of your game code, but it's not enough to reverse-engineer back to the original game.

Hang on didn't somebody else post that memory problem with cc1plus. I'm trying to remember what happened there.

[polygone]

Yes they did, somebody called Wishdream on the irc. I didn't know what it was causing it so I told him to wait for Josh but he never came back.

It was probably the same problem, he said cc1plus was spammed like 20 times in the task manager and I initially figured it was MinGW screwing it. But in the IRC he said he also tried it on 3 different systems and they all had the same issue, the only thing apparently common was that they were all Win 7. I'm not sure on the validity of his testing though, but the specs of the systems he gave me were:

AMD Athlon(tm) 64 X2 Dual Core 4800+ 2.50GHz CPU, 1GB RAM 64-bit Win 7 OS, AMD Radeon HD 6670 1GB GFX Card, Realtek HD Audio
Win 7 32-bit 2GB RAM laptop
Win 7 64-bit 2GB RAM Laptop

Although thinking about it now, I'm considering whether it was the game size doing it and if he was then just testing the same game. SuperRiderTH do other games or a blank room work correctly for you?

[SuperRiderTH]

Other games do work. It is only this one causing a problem.

This game right now is very WIP, and I just started to move things over to ENIGMA and start to fix missing functions, etc. It is a modification of the Sonic Revival Engine, with Super Ring Engine stuff ported into it.

So here is the Preprocessor folder.

Ah so can you upload the game, then we can see if it happens for anybody else.

[polygone]

By the way with a game as large as the one you're trying it's highly unlikely that it will be compatible with ENIGMA right now anyway.

[SuperRiderTH]

Really the only problems are the no inheritance, variable_local_get/set/exists, and compiling. So not much problems. Just have to remake some things.

[polygone]

ok. can you upload the game then? google drive has fast upload if you want something quick.

[forthevin]

IDE_EDIT_objectaccess.h is ~40 MB, which is definitely the cause of the issue. This means that the problem is as far as I can tell the same as for Iji: the game in question is too massive measured in terms of lines of code and number of actions for ENIGMA to handle it properly at the moment. The reason is that the current game compilation process does not scale well. SuperRiderTH, can you verify that the game is indeed very large in terms of lines of code and number of actions?

We do plan to fix the issue in the future, but it may be a while before the issue has been fixed.
