cannot run ybc excutable from linux download about ybc HOT 10 CLOSED

Do you mean the 'ybc' executable? It's just an ordinary ELF32 file, you shouldn't have any issues running it. Depending on your distribution, you may have to install a (few) package(s) before you can run 32bit executables on a 64bit installation. Maybe that's the issue?

Hi John,
many thanks for your help. Yes I mean ybc executable
You are right.
$ dpkg --add-architecture i386
$ ldd ./ybc
points to missing libraries, eg
$ apt-get install -y libstdc++6:i386
And now ldd does not say any libs are missing. But
$ ./ybc
Gives segmentation fault

Note that I am doing all of this inside a docker container
$ docker run -i -t ubuntu:14.04 /bin/bash
which may be a cause. For example, I appear to be unable to strace the seg
fault?!

I'm not really up on linux that much. I just want to use it to to set up
languages on http://cyber-dojo.org to encourage devs to do coding dojos
(from a browser but with security on the server provided by docker), and to
try and raise some money to buy Raspberry Pi'es for kids.

Thanks
Jon

I tried inside a 32 bit docker container
moby/moby#611
https://registry.hub.docker.com/u/besn0847/ubuntu32/
Same problem. Still seg faults

from ybc.

Bump? Same thing happens to me, and I can't build it myself because I have no clue what language this is written in.

I think a bmx file is a BlitzMax file.

Hi everyone. I'm sorry I missed this issue the first time it was brought up. I happened to just not have logged in to GH for a while around that time and it flew under my radar.

1. yes, the language is BlitzMax. It's a proprietary compiler, which means if you haven't heard of it building the project will be difficult - that was kinda part of "the joke" at the time. There is an open-source BMX compiler project here, but I don't know how complete it is.

2. I haven't been able to reproduce yet. Will try again. The unofficial list of packages recommended to run a minimal BlitzMax application is libglu1-mesa:i386 libfreetype6:i386 libxft2:i386 libxpm4:i386 libasound2:i386 libpulse0:i386 libopenal1:i386.

Sorry again for not paying attention to this sooner. Thanks for reporting.

@Leushenko All were installed. Still segfaults.

Does BlitzMax have a way of inserting debugging symbols? If so, I could pop it in GDB and see where it's segfaulting.

CURSE YOU PROPRIETARY COMPILERS!!!!!!!! :|

I'm still keen to add B to cyber-dojo.org
I just need a compiler that can run on linux
Cheers
Jon

OK... gone from "cannot reproduce" (old system) to "always reproduce" (everywhere else): I actually can't even build&run a Hello World or empty file without seeing the same error as the others above, so I'm choosing to blame this one on BlitzMax. Max's support for Linux has always been more or less pre-alpha and gets worse every year as it is pretty much unmaintained.

Luckily this only seems to affect release builds on my machine, so I am being hilariously unprofessional and have replaced the prebuilt version with a debug build instead, which still works correctly - for me.

Needs a rewrite in a different language, I guess.

from ybc.

@Leushenko It works now! Thanks!

Glancing at the source code style, you might like using a language like Nim, which has variant types (to avoid comparing to a string overly often) and plenty of other niceties.
