The tech notes for amd64 say that a link from /lib/ld-linux.so.2 to /emul/..../ld-linux.so.2 should have been automatically created. But it is not created! Unless I create the link by hand (which I did with the command below), no 32-bit applications work. This makes it impossible to emerge some x86 binary builds (e.g. openoffice-bin) because the ebuild tries to run 32-bit applications in the process. ln -s /emul/linux/x86/lib/ld-linux.so.2 /lib/ld-linux.so.2 After this link is created things seem to work fine. Reproducible: Always Steps to Reproduce: 1. emerge emul-linux-x86-baselibs 2. try to run any non-statically-linked 32-bit app (e.g. acroread) 3. Actual Results: bash: appname: No such file or directory Expected Results: Should have made a link from /emul/linux/x86/lib/ld-linux.so.2 to /lib/ld- linux.so.2 kugelfang@gentoo.org 2004-05-02 14:17:40 0000 phi dvandyk # ll /lib32 lrwxrwxrwx 1 root root 19 May 2 23:06 /lib32 -> /emul/linux/x86/lib phi dvandyk # ll /lib32/ld-linux.so.2 lrwxrwxrwx 1 root root 11 May 2 23:06 /lib32/ld-linux.so.2 -> ld-2.3.2.so That's the normal setup for Gentoo/amd64. It works for all 32bit binaries i know in portage. Ah, and please provide the md5sum of emul-linux-x86-baselibs-1.1.ebuild. btco@linux.ime.usp.br 2004-05-02 18:02:23 0000 The md5sum for my emul-linux-x86-baselibs-1.1.ebuild is 5a6f8865e339320acec47c35a9fbd1e2. Without creating the link by hand, here's what happens: # ACCEPT_KEYWORDS=x86 emerge acroread [success] # ldd /opt/Acrobat5/Reader/intellinux/bin/acroread /usr/bin/ldd: line 1: /lib/ld-linux.so.2: No such file or directory ldd: /lib/ld-linux.so.2 exited with unknown exit code (127) # /opt/Acrobat5/Reader/intellinux/bin/acroread sh: /opt/Acrobat5/Reader/intellinux/bin/acroread: No such file or directory After I create the link by hand: # ldd /opt/Acrobat5/Reader/intellinux/bin/acroread libXt.so.6 => /emul/linux/x86/usr/X11R6/lib/libXt.so.6 (0x55580000) libXp.so.6 => /emul/linux/x86/usr/X11R6/lib/libXp.so.6 (0x555d1000) libXext.so.6 => /emul/linux/x86/usr/X11R6/lib/libXext.so.6 (0x555d9000) libX11.so.6 => /emul/linux/x86/usr/X11R6/lib/libX11.so.6 (0x555e7000) libm.so.6 => /lib32/libm.so.6 (0x556ad000) libdl.so.2 => /lib32/libdl.so.2 (0x556cf000) libc.so.6 => /lib32/libc.so.6 (0x556d2000) libSM.so.6 => /emul/linux/x86/usr/X11R6/lib/libSM.so.6 (0x557ff000) libICE.so.6 => /emul/linux/x86/usr/X11R6/lib/libICE.so.6 (0x55807000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x55555000) # /opt/Acrobat5/Reader/intellinux/bin/acroread [runs normally. Actually it complains because it doesn't like to be run by hand, but that shows that it is at least starting] By the way, # uname -a Linux gandalf 2.6.3-gentoo-r2 #1 Wed Apr 28 14:15:50 BRT 2004 x86_64 12 GNU/Linux It seems to me (at least that's what I always read in books, etc) is that dynamically-linked binary applications have the string '/lib/ld-linux.so.2' hard-coded into the executable, so ld-linux.so.2 must be present at that specific location... kugelfang@gentoo.org 2004-05-03 05:32:46 0000 Ok, my fault. There _needs_ to be a /lib/ld-linux-2.so. The necessary symlinks should be created by the ebuild but that fails, cause ${D}/lib doesn't exist :-/ Fixed now. Thanks a lot Bruno. btco@linux.ime.usp.br 2004-05-04 02:35:31 0000 thanks for looking into it!
