I have installed Fedora 21 on my Raspberry Pi 2 using BerryBoot, and when I run minecraft-pi, I get the error: libbcm.so not found. I have already installed mesa-libEGL to fix the error: libeglv2.so not found, but I cant seem to install libbcm.

  • Where did you get minecraft-pi from? – goldilocks Jul 19 '15 at 20:53
  • @goldilocks from pi.minecraft.net – patrick Jul 20 '15 at 10:47
  • The odd thing is that libbcm.so looks like it could be something pi-specific (if 'bcm' refers to Broadcom, which it often does), but there is no such library included in Raspbian, no such library found by searching normal Debian repos, and no such library searching normal Fedora repos. – goldilocks Jul 20 '15 at 13:52

I think you mean libbcm_host.so. The minecraft-pi executable requires the following:

> ldd minecraft-pi 
    libGLESv2.so => /usr/lib/vc/libGLESv2.so (0x4a3b0000)
    libEGL.so => /usr/lib/vc/libEGL.so (0x4a340000)
    libbcm_host.so => /usr/lib/vc/libbcm_host.so (0x4a390000)
    ^^^^^^^^^^^^^^
    libpng12.so.0 => not found
    libSDL-1.2.so.0 => not found
    libstdc++.so.6 => /lib/libstdc++.so.6 (0x4b908000)
    libm.so.6 => /lib/libm.so.6 (0x4a410000)
    libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x4a2d0000)
    libc.so.6 => /lib/libc.so.6 (0x4a180000)
    libpthread.so.0 => /lib/libpthread.so.0 (0x4a308000)
    libX11.so.6 => /lib/libX11.so.6 (0x4a788000)
    libvcos.so => /usr/lib/vc/libvcos.so (0x4a378000)
    libdl.so.2 => /lib/libdl.so.2 (0x4a2f8000)
    librt.so.1 => /lib/librt.so.1 (0x4a5c8000)
    libvchiq_arm.so => /usr/lib/vc/libvchiq_arm.so (0x4a330000)
    /lib/ld-linux-armhf.so.3 (0x4a150000)
    libxcb.so.1 => /lib/libxcb.so.1 (0x4a8a0000)
    libXau.so.6 => /lib/libXau.so.6 (0x4a928000)

That was checked on a pidora B+. The library is one that is special to the pi, hence the /usr/lib/vc path.

It's in the github firmware repo here. You can try getting just it specifically, then try grep "vc/lib" /etc/ld.so.conf.d/* to see where to put it.

If that turns up nothing, create a /opt/vc/lib directory, owned root and set mode 755, place the library in there with the same permissions, then:

echo "/opt/vc/lib" > /etc/ld.so.conf.d/myrpi.conf
ldconfig

When you run ldd on minecraft-pi now, as up top, you should see that library linked correctly. Please also read my note at the bottom here about /opt/vc.

You may have further problems, but this should solve that one.
