 Posted: Sat Sep 15, 2007 7:12 pm Post subject: Cannot run 32bit applications [SOLVED] |
 |
|
I can run any of the 32bit applications that I have installed when I do I get a "No such file or directory" error, even though the file clearly exists.
For example
| Code: |
bob etc # /opt/firefox/firefox-bin
bash: /opt/firefox/firefox-bin: No such file or directory
bob etc # file /opt/firefox/firefox-bin
/opt/firefox/firefox-bin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped
bob etc # strace /opt/firefox/firefox-bin
execve("/opt/firefox/firefox-bin", ["/opt/firefox/firefox-bin"], [/* 60 vars */]) = -1 ENOENT (No such file or directory)
dup(2) = 3
fcntl(3, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 7), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2b7340ca1000
lseek(3, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek)
write(3, "strace: exec: No such file or di"..., 40strace: exec: No such file or directory
) = 40
close(3) = 0
munmap(0x2b7340ca1000, 4096) = 0
exit_group(1) = ?
Process 27961 detached
|
I get the same problem with games like doom3 or neverwinter nights, acroread, and wine. I have already checked that other non-32bit applications on the /opt partition can run, so I don't think it is a permissions problem. Also I am using the 2007.0/desktop profile.
| Code: |
/etc/make.profile -> /usr/portage/profiles/default-linux/amd64/2007.0/desktop/
|
Finally I also see this problem when trying to emerge wine. Portage can not create a file that it can be executed.
It fails with the error:
| Code: |
checking for x86_64-pc-linux-gnu-gcc... x86_64-pc-linux-gnu-gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables

EDIT: Solution
I actually finally solved this with out reinstalling gentoo so I am very happy and I'll share what I did and what I think was wrong.
This turned out to be another multilib problem probably created back when I switched to 2007.0 profile. One of the mistakes I did was I played around with the multilib useflag trying to fix things, before I learned it was deprecated. In addition to wine not compiling I also couldn't get app-emulation/emul-linux-x86-java to emerge. So I thought something might be wrong with gcc and tried remerging it to discover it to would not emerge. It failed with and error saying it could not find /usr/include/gnu/stubs-32.h. Which should be included by glibc.
I followed the advice in this post. And downloaded glibc, binutils, and gcc from tinderbox. Then used emerge -k to install the prebuilt packages. And right after that everything worked.

Okay, checked those two posts I have "sandbox" turned off, and my CFLAGS appear to be okay. I noticed the /emul/linux/x86/lib file dosen't exist. I don't know if that is the problem or how to fix it.
| Code: |
CFLAGS="-O2 -march=athlon64 -pipe -fomit-frame-pointer"
CFLAGS_x86="-m32 -L/emul/linux/x86/lib -L/emul/linux/x86/usr/lib"
FEATURES="ccache distcc distlocks metadata-transfer parallel-fetch sfperms strict unmerge-orphans userfetch"
|
And I do have the emulation enabled.
| Code: |
bob icfp # zcat /proc/config.gz | grep IA32
CONFIG_IA32_EMULATION=y
CONFIG_IA32_AOUT=y
|
emerge --info

that should be "-Wl,-O1" You've left out the comma.

Your right, it should be that, but that is not the problem. I actually thought that the LDFLAGS might be at fault and removed them, but that didn't change anything. So when I put them back in I missed the comma.
I have remove the LDFLAG completely now.

Well, it's a guide, not gospel. -Wl,-O1 is quite safe and only affects shared libraries, and there's no way it could cause this. Also, it's perfectly acceptable for submitting bug reports, which is what the optimization guide is warning about: stuff that'll get your bugs marked INVALID. I see it all the time in the reports on bugzilla, and it's never once been singled out or even noted by any dev responding to any bug that I've ever seen. I think the guide is probably referring about more exotic stuff like having a bunch of -z 'keyword' options and messing around with hashvals or the -Bdirect stuff that was a sort of minor ricing trend for awhile. --as-needed could be included in that warning I suppose, but even though it's not officially supported, for all intents and purposes, it is. --as-needed bugs are not only accepted and fixed, but have their own tracker on Gentoo's bugzilla.

BlinkEye, not sure how this is related but $CC is the universal name for the systems c compiler. Back in UNIX days it was actually callled cc. In your case it has been set to g++ which is proablly okay because C++ can compile C code.
On a side not the my origional problem still exists, and I haven't been able to solve it.

Utlo, sorry about that. This is obviously the wrong thread I posted to. Some guy had problems with compiling and I wanted him to check that he didn't set CC to a C++ compiler or compiling will brake at some point.
