problem with linux: missing

a fresh install of moose image failed to start on a number of Linux machines because of missing libraries

the missing dependencies are libGL and libX11 that for some reasons were not installed (but it was a running linux with graphical interface).

See below

$ ldd vm-display-X11

more info on this,

On my own computer, the dependencies are not the same:

---

$ ldd pharo
    linux-gate.so.1 =>  (0xf7751000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf76ce000)
    libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf76c9000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf76ab000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf74f5000)
    /lib/ld-linux.so.2 (0x565c6000)

Specifically, the two missing libraries (for hte others) are not requested on my computer.

So why were they needed in the other cases? (I am using the same pharo5 as they do)

there should be a way to test that.
Not too sure how. May be an installer in the form of a headless image using the system ldd (see above) command ?

If you are using Pharo on a Linux 64 bits system you need the Linux 32
bits librararies. There are not installed by default on Linux.

You can follow these procedure to install the missing 32 bits libraries:

thanks for both replies.

- I was under the impression that the 64bit VM was precisely intended to remove dependencies on 32bits libraries ... ?

- and yes, you are right, I should have called on the plugin, not the vm

thanks again

The vm-display-X11
will be dynamically loaded, that is why you don't see the GL/X11 dependency if you ldd on the vm (pharo-executable).

If you are on a 64Bit machine, you need to have 32Bit libraries for X11/GL . And yes, it would be nice to have a headless vm not to depend on the display library stuff.

I don't knwo. Did you installed the 64bits VM and Pharo 64 bits image. I
think it is still WIP.

The reason is that the vm binary is 64bit but the interpreter is for 32bit images. Therefor the plugins are 32bit, too. If there will be a 64bit vm plus image the dependencies would go away. We are close to that but not there.
