New Linux Issue?

[Lebeau]

NGD, HELP! Today (7/29/2016), I logged into game via STEAM. I had been ingame just a few hours before. STEAM did a brief update to CoR (it has done this twice recently, with no issue). The CoR login screen functioned normally. It reached the character selection screen normally. I chose a character & pressed play. It loaded the loading screen (got at most 5-10% of load) & then immediately crashed to desktop. I tried repeatedly, even rebooted pc, but same result. I have up-to-date Linux 14.04 64-bit OS, Pentium D 2.8 CPU, & Nvidia GT218 GPU. A ticket has been submitted, but is anyone else also having this issue since the STEAM patch? :confused:

[_Enio_]

The linux rolauncher binary has been updated a few times recently. It shouldnt be related to issues coming from the game binary itself.

Do you have any more info regarding your system and linux distribution?

-It's all 'Greek' to me, Enio, but what other info do you require, & how do I obtain it?

[_Enio_]

Only thing i see there is errors about the 32bit steam overlay library, that doesnt have to mean anything though.

I dont play via steam, so i dont know how to debug it probelrly. You could consider trying the non-steam version. Thats easier to debug aswell.

All you need is the 64bit rolauncher, and the needed libraries. And patience since it will download alot of stuff.

In case you want to try it - I bundled those in my dropbox >>here<< (https://www.dropbox.com/s/t6sfy5udirsn9rj/regnum.tar.gz?dl=0).

Just extract this in your homefolder and run the rolauncher binary and it will download the game stuff. Better then the one from the website which is full of outdated resources.

Edit: You might have to make it executable by either using context menu in some file manager or via commandline with chmod +x rolauncher

[Lebeau]

I will definitely consider the option, but I want to see if NGD/STEAM debugs their product 1st. I know next to nothing about computers or this OS, & I don't know what the current issue is now, but I do know that the native Linux version of CoR crashes even quicker on this dinosaur of a pc than what I have now thru STEAM. I have tried the native CoR version repeatedly thru 3 Linux OS upgrades over a few years to no effect, & each time had to run game thru STEAM in order to play, until now. I might also upgrade to 16.04 Xubuntu LTS & try running it then, but I had wanted to wait until 16.04 is as thoroughly proofed & as stable as 14.04. Thanks for the help, Enio, I'll keep my fingers crossed, & if all else fails, try your advice in a week or so....

-Repeat..."what other info do you require, & how do I obtain it?"

[_Enio_]

-Repeat..."what other info do you require, & how do I obtain it?"


Well its rather technical. These mostly rely on running the game with some debug tool active, however with steam i am not sure, i did read it executes games in some kind of sandbox, which might make stuff difficult.

You say you crash after you press enter world, so you can get into character select successfully?

If yes, there are 2 tools that can get you info about whats going on right before the crash. strace logs system calls (file open calls and stuff) that can get hints at what "part" of execution the crash occurs, or what files or actions system-wise are involved. gdb is the main linux debugger, which can give insight into what program was executing when the crash occurred, this is rather cryptic however when the binary isnt a special debug version, however still can get some hints)

Now if you can get into character screen, and you can produce a crash by pressing enter, you can use these tools by attaching them to the game process.
So what you need to do after getting to character screen (in windowed mode)

strace


Fire up a console
Find out the Process id (PID) of the game binary ( either with the help of top, or by issuing ps ef | grep -v grep | grep game) <--- if you dont get a result here, stop. Then steam runs stuff in a sandbox where we cant just look in easily.. Then you need to try it with the standalone game version.
Attach strace to the process (strace -o <some_filename> -p <PID>)
Produce the crash
Stop the strace logging in console by issuing Ctrl+C
Upload and share the file (Shouldnt contain private info, but feel free to pm)

gdb


Fire up a console
Find out the Process id (PID) of the game binary ( either with the help of top, or by issuing ps ef | grep -v grep | grep game)
start gdb on commandline (just enter gdb)
In the gdb console that now shows up, enter attach <PID>
Produce the crash
gdb console will say something about the crash (received SIGABORT or SIGSEV or whatever)
enter "backtrace" or "bt"
Copy paste the printed result here
Btw, you can exit the gdb console by issuing quit



That should at least shed some light on where the problem lies. But its a bit technical.


If you have any questions, dont hesitate to ask (here or pm)


Good luck!

Edit: You might have to install these tools from the ubuntu packet manager.

[Lebeau]

I tried the bundle you suggested. It ran normally for extraction & install. It loaded the RO-login screen when the RO-app was opened. It began a 4.6MB download on that login screen. It finished all of it, then the app immediately crashed to desktop. The RO-launcher won't do anything now, at all. It won't even run in a terminal so we can look at what is going on. The terminal opens, nothing appears, & a fraction of a second later, the terminal crashes to desktop. No luck (except bad). Just feelin' kinda' busted & disgusted...(but thanks for the effort, not your fault).

:facepalm3:

So, I ran the program in terminal via ... :~$ /home/admn/regnum/rolauncher &
& it spit this out:

[1] 3703
... :~$ /home/admn/regnum/rolauncher: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: No such file or directory

Yet, the file & directory DO exist afaik.

-As to the other suggestion, I'm pretty sure I'll have to install those tools, as I use a stripped down GUI (XFCE) that has none of these things I'm fairly sure. Will try to follow your directions above & get you more info when my mood improves sufficiently, & I have the time & patience. Then, I'll try obtaining the native-RO info 1st, as you said you were unfamiliar with STEAM, & that it's easier to debug the native version.

Download the file from Enios dropbox and try

LD_PRELOAD=path/to/file/libjpeg.so.62 ~/regnum/rolauncher

Also replace your rolauncher with the one Adrian posted. https://www.championsofregnum.com/forum/showpost.php?p=1862492&postcount=33

Maybe it helps.

[_Enio_]

You need to cd into that directory and then run ./rolauncher. Sorry i shouldve mentined that: Binaries are looking in the current directory for libraries first, and then in the default library paths (usually /usr/lib/ and /usr/local/lib/) So in your case (seems you are in ~ = /home/admn) it looked in your home directory and didnt find that lib..

so do a cd /home/admn/regnum && ./rolauncherAnd try again.

The 4Mb update just meant it updated the rolauncher binary itself. To be able to start rolauncher from any path, you could "install" those libraries by copying it in the respective library folders. I personally dont mess with those though, only let packages i installed via some package manager add stuff there (so i can track it).

Edit: You can also do something like this LD_LIBRARY_PATH=/home/admn/regnum /home/admn/regnum/rolauncher this temporarily adds the folder ~/regnum to the search path. Im not sure about the LD_PRELOAD skit mentioned, it should work similarly, but per-library. You'd need to also preload the libpng12.so.0 then.

SO,

What the hell is a "libjpeg.so.62"? Why don't I have one already? Where do I get one?

SO,

....after asking meself these questions, I found out I'm not alone in this issue. Others in unrelated app installations also suffer a lack of "libjpeg62", tho not sure why. I then installed it. I ran native-RO (the one that wouldn't do ANYthing before) in a terminal. The RO-loader loaded normally. It patched 21 MB or so, then I got to server selection screen. I choose a server, it went to the loading screen normally, but took a long while getting resources, as is normal 1st time in. It got to character selection screen, I pressed play, & RO crashed, the terminal spitting this out:

[1] 14832
... :~$ [S_API FAIL] SteamAPI_Init() failed; SteamAPI_IsSteamRunning() failed.
[S_API FAIL] SteamAPI_Init() failed; unable to locate a running instance of Steam, or a local steamclient.so.

SO,

WTF?! Why is the native version of RO looking for STEAM ffs?! Am I missing far more here than I realize?! /me is stupid ya' know...

:facepalm3:

[Adrian]

Have you tried installing the library?

sudo apt-get install libjpeg62

[Lebeau]

Have you tried installing the library?

sudo apt-get install libjpeg62

Yes, I did, but thanks (sorry, I'm bad with the post-posted edits):

"...Others in unrelated app installations also suffer a lack of "libjpeg62", tho not sure why. I then installed it. I ran native-RO (the one that wouldn't do ANYthing before) in a terminal..."

-Adrian, is it normal for the linux-native version of RO to look for STEAM? It cannot find it of course. It's not there to find.

[_Enio_]

This is very odd. Does the user you log in to ro decide if it has to run with steam?

Also, just out of curiosity, can you confirm that that libjpeg.so.62 is infact located in /home/adm/regnim folder?

Very sorry for your issues, hope we get it nailed somehow. Why it is asking for steam when steam isnt even launcching it is beyond my knowledge..

[Lebeau]

...Also, just out of curiosity, can you confirm that that libjpeg.so.62 is infact located in /home/adm/regnim folder?...

Is it supposed to be in home/admn/regnum/live/libs? If so, then it is NOT. NO libs at all in the "libs" folder there. Tried cntl-h & find nothing hidden, so...

[schachteana]

I could actually confirm OPs issue:
./rolauncher: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: No such file or directory
(I freshly upgraded to ubuntu 16.06 yesterday, some packages were uninstalled)

But after installing libjpeg again (see adrians post), everything worked properly again.

(Note: There are NO lib files whatsoever in the live folder. And the lib folder is totally empty. All the libs which can be found in a windows installation seem to be encapsulated within the binaries)

[_Enio_]

I did some debugging with Lebeau (kudos to your patience!)

Sadly, its way beyond library stuff. In the recently compiled game binaries, the CPU instructions LAHF/SAHF are used that is not compatible with some of the older 64Bit CPU

The "bt" on the crash:

specifically missing the flag lahf_lm: Load AH from Flags (LAHF) and Store AH into Flags (SAHF) in long mode

Questions:
* Did something on the compile flags change / or the compiler version change in one of the recent releases?
* Can this be fixed on NGDs end?

Thank you Enio, that was some great debugging. Of course it can be flagged.

Lebeau, which processor do you have? Please give us as much detail as you can.

Just want to post an update on this issue.

For now we worked aound by getting the 32Bit version running on the 64Bit system.

However this is nothing a normal user will be getting right. Theres alot of dependencies you need to install in 32Bit. It involved starting the "game" binary without rolauncher to find out which 32Bit-libs were missing and resolving which ubuntu packages might contain it etc.

tl;dr: If there's no good reason to break compat with some of the older 64Bit CPU, i.e. some great improvements in performance for the newer, i think it would be worth getting this fixed (especially since RO might be played on older hardware in some parts of the world).

[Lebeau]

I did some debugging with Lebeau (kudos to your patience!)...

Not the hero here, at all, you are (kudos to YOUR patience!).

[Adrian]

Well, we finally got to the real problem!

You never had a 64-bit version working in the past. We released the 64-bit version in Steam some weeks ago. You were running the 32-bit version and everything was fine until we made available the 64-bit one.

Even if we set the flag to avoid lahf/sahf, LuaJIT needs it and, of course, adds it.

The possible solutions would be:

- Downloading the 32-bit installer from our website and play outside Steam.
- Find a way (I don't know if it's possible) to force Steam to use the 32-bit architecture for CoR.

So, there is no way for us to fix it. Sorry! :(

[_Enio_]

I was curious, and turned out - there is another option.

However first a quick note - even when supplying "-mno-sahf" to gcc when compiling LuaJIT - it will not remove it - because it is INLINE asm, this will be translated verbatim.

So what are we using.

[enio@thinkpad ~]$ cd regnum/live; strings game | grep LuaJ
LuaJIT 2.0.2
Have to say i checked 2.0.4 first, thats why i tested 2.0.3 too if it already works:
[enio@thinkpad LuaJIT-2.0.2]$ objdump -d src/libluajit.a | grep -A3 -B2 fprem
2924: dd 42 08 fldl 0x8(%rdx)
2927: dd 02 fldl (%rdx)
2929: d9 f8 fprem
292b: df e0 fnstsw %ax
292d: 9e sahf
292e: 7a f9 jp 2929 <lj_ff_math_fmod+0x28>

[enio@thinkpad LuaJIT-2.0.3]$ objdump -d src/libluajit.a | grep -A3 -B2 fprem
2921: dd 42 08 fldl 0x8(%rdx)
2924: dd 02 fldl (%rdx)
2926: d9 f8 fprem
2928: df e0 fnstsw %ax
292a: 9e sahf
292b: 7a f9 jp 2926 <lj_ff_math_fmod+0x28>

[enio@thinkpad LuaJIT-2.0.4]$ objdump -d src/libluajit.a | grep -A3 -B2 fprem
291f: dd 42 08 fldl 0x8(%rdx)
2922: dd 02 fldl (%rdx)
2924: d9 f8 fprem
2926: df e0 fnstsw %ax
2928: 66 25 00 04 and $0x400,%ax
292c: 75 f6 jne 2924 <lj_ff_math_fmod+0x28>

Isnt that funny? Thats the only occurrence of remainder calculation in LuaJIT, and they changed it in 2.0.4 (current stable release) to use and instead of sahf (which does the same as test in the other thread, maybe its faster).

Here is the github commit in question, sadly no reasoning stated, however its labelled "x86/x64: Avoid use of SAHF instruction." (https://github.com/LuaJIT/LuaJIT/commit/c03be1210c5334e58958d95ea0412c20c3eb0128)

tl;dr: SHAF is not used anymore in LuaJit since version 2.0.4, so get it updated! :P

OMG, I feel ashamed :sifflote:

Tomorrow we will test updating it and see if everything still works, ha!

Lol, don't be! It was a lucky find driven by curiosity on the workings of the "-no-sahf" switch.

In case there are incompatibilities regarding other changes in 2.0.3/2.0.4 - it should be very easy to cherry pick this change into 2.0.2 too.

Good luck!

Good news. It works and sahf is not there anymore. We'll be uploading this on Monday and I'll let you know here so you can test.

Awesome, thanks for the update.

We uploaded the 64-bit version with the changes to our experimental repository. Lebeau, please tick in your launcher advanced options "Use experimental client" and let us know if the problem is gone. Thanks!

Adrian, Enio, I'm extremely grateful for all of your time & effort that have been expended on my (& perhaps others') behalf in this matter, & I truly thank you both very much indeed. There's currently a hitch of sorts though, entirely on my end. Currently, I'm away from home & desktop, with only a tablet for internet access, & so, cannot test this revamped 64-bit game version. Regrettably, I'll be away for another two weeks, but will install, test it, & then, post my findings here as soon as I get settled back in at home. I duly apologize for being the roadblock in this & for this unavoidable delay, but summer vacation at the lake, cookouts, vino & an exceptionally large & comfy hammock hung in the shade are not at all to be missed if at all possible..../me raises glass in salute....

:o

I can confirm the absence of that evil sahf instruction, and i did not notice any side effects on my machine (A recent intel i5 cpu).

Final checklist, go.

Regnum 64-bit installed ... check.

Experimental client enabled ... check.

Authorization code entered & authorized ... check.

Good to go, begin countdown to launch sequence....
