[solved] Cannot find MCServer executable - Linux x64

[ctag]

Hello!

I'm not particularly new to building things with make, but I seem to be missing something here.

I first tried downloading the Linux x64 tar file and extracted it.

Code:

$ wget http://ci.bearbin.net/job/MCServer%20Linux-x86-64/lastSuccessfulBuild/artifact/MCServer.tar
$ tar xvf MCServer.tar

But when I try looking for the executable in ./MCServer/ it isn't there:

Code:

~/MCServer$ ls
crafting.txt  furnace.txt  hg  hg.supp  items.ini  monsters.ini  Plugins  README.txt  vg  vg.supp  webadmin

Ok, then I tried compiling it myself:

Code:

$ git clone https://github.com/mc-server/MCServer.git

I couldn't copy all of the make output over SSH, but it completed without any apparent errors.

Code:

The MCServer file still isn't there?! Even after make claims to have linked it. I'm pretty confused, the directions seemed quite straightfoward. Have I missed some step to running the server?

Thanks,

Stupid question, but you did use cmake first, didn't you? There wouldn't be a makefile without it, probably, but I just had to ask. Can't be much more help otherwise, perhaps someone from the *nix community can shed some light? Bearbin? SamJBarney?

Hi xoft,

Yes, I ran cmake beforehand with the RELEASE flag.

Code:

~/MCServer$ cmake . -DCMAKE_BUILD_TYPE=RELEASE

Out of curiosity, what happens when you grab the current version from the Github repo and try to build it? Also what kind of linux are you running?

[ctag]

Hi SamJBarney,

Unless I'm mistaken, that's what I'm doing. I [git clone] the current source from https://github.com/mc-server/MCServer and build it with cmake and make.

Both ways, building or grabbing the .tar archive, result in a MCServer directory with no MCServer program (or settings.ini for that matter).

Thanks,
-CTAG

[SamJBarney]

CTAG,

Ah. Missed that. Sorry.
Hmmm.... That's a bit weird. I'm running a build right now, with the same parameters that you did just to see if I can reproduce it. And the results are in! I just ran a build on my machine, and I am getting no executable in the MCServer directory. For some reason cmake is putting it in the src directory.

Check to see if src/MCServer/MCServer exists for you.

Respectfully,
Sam

I'll post a fixme to Github so that this gets fixed soon.

SamJBarney,

That was it! I copied the MCServer out of src and into the correct folder, the server now runs. This is a pretty odd scenario, especially since make claims to be linking "MCServer/MCServer" xP

Thank you,
-CTAG

[SamJBarney]

CTAG,

No problem. I think its just the fact that CMAKE is using a relative path for when it is supposed to be in the root directory, but it is still in the src directory.

Respectfully,
Sam

[ctag]

OK, that makes sense. Thanks again for the help.

Hey there, just saying I had the exact same issue with the Raspberry Pi after building it from the Git repositery. As described, it was placed on the src directory.
