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.

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)

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

linux-gate.so.1 => ��(0xf7766000)
libpthread.so.0 => /lib32/libpthread.so.0 (0xf76ff000)
libGL.so.1 => not found
libX11.so.6 => not found
libc.so.6 => /lib32/libc.so.6 (0xf754b000)
/lib/ld-linux.so.2 (0x5661f000)

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 ?
