 Posted: Sun Aug 02, 2009 7:42 pm Post subject: Running 32-bit binaries on AMD64. Flash player (not plugin!) |
 |
|
What should I do if I need to run a 32-bit closed-source binary on a 64-bit system? What is the best way to get 32-bit libraries?
I downloaded 32-bit Adobe Flash player (not a browser plugin) from http://www.adobe.com/support/flashplayer/downloads.html
When I tried to run it, it demanded 32-bit libnss3.so.
I figured the libraries from dev-libs/nss from Sabayon should work. I unpacked the libraries to the same directory and started the player as LD_LIBRARY_PATH=. ./flashplayer
Then it demanded libnspr4.so. I did the same with dev-libs/nspr from Sabayon.
After that, flashplayer started, reported multiple errors
(flashplayer:26323): Gtk-WARNING **: /usr/lib64/gtk-2.0/2.10.0/engines/libxfce.so: wrong ELF class: ELFCLASS64
and stopped with "Segmentation fault".
strace showed that flashplayer tries to open (unsuccessfully) a number of 32-bit libraries. It seems that libcurl.so.4.1.1 from Sabayon can replace libcurl-gnutls.so.3, but there's nothing like libldap-2.4.so.2. How should I compile it from source? Also it seems that the program tries to use 64-bit /usr/lib64/gtk-2.0/2.10.0/engines/libxfce.so instead of 32-bit /usr/lib32/gtk-2.0/2.10.0/engines/libxfce.so. What can I do about that? |

app-emulation/emul-linux-x86-* and *-bin

There is no support for compiling normal packages for x86 on amd64 currently. Use binary packages or compile them manually. |

I meant besides that. Most libraries aren't available that way.

How do I compile them manually on 64-bit system? What gcc/configure/make/what-else? switches do I need? |

The few times I've needed to do it, I just got fedora binaries and manually placed them in /usr/lib32

don't destroy yourself brain, just install this one with the same USE flags
PS google://32bit chroot

However, flash-libcompat-0.2.tar.bz2 does have the necessary libraries, so thanks.
And why does it keep writing | Code: | | Gtk-WARNING **: /usr/lib64/gtk-2.0/2.10.0/engines/libxfce.so: wrong ELF class: ELFCLASS64 |
?
Install a parallel 32-bit system? I was hoping for a less disk-hungry solution. Even so, what are the ways to determine which libraries a binary needs? |

Any distribution will do. Sabayon just has the most familiar names and the most similar dependencies.

/usr/lib32 becomes a mess this way  Unless they are placed by an ebuild. That's why a temporary directory and LD_LIBRARY_PATH until everything works. |

A 32-bit program has decided to manually load a 64-bit library, which doesn't work. There's nothing you can do about this except to file a bug report with the program's authors.

"ldd /path/to/my/program" will show which libraries the program uses; any library without a matching path on the right-hand side (I believe ldd prints "unresolved" here) needs to be installed. You'll want a 32-bit chroot simply because that's the easiest way of building 32-bit libraries, but a basic build system isn't that large. |

Thanks! That was the answer I needed.

Yes. Just like that. Thanks. |
