sure it is the conftest is a 32bit file and if it says "No such file or directory", chances are good multilib is screwed on your box
*** Bug 130361 has been marked as a duplicate of this bug. ***
I was unable to emerge glibc-2.3.5-r2, glibc-2.3.5-r3 and glibc-2.3.6-r3. Error message was: configure:7465: error: cannot compute sizeof (long double), 77 My bug report (Bug 130361) has been marked as a duplicate of this bug. I was able to solve this bug (for me) by enabling IA32_Emulation (CONFIG_IA32_EMULATION=y) in my kernel configuration. Indeed IA32_Emulation seems to be the default for current Gentoo-AMD64. I think I switched it off when compiling a fresh kernel. Compiling other software was working well, but I found a remark that compiling gcc fails with the same error message if IA32_Emulation is not enabled. After compiling the current kernel kernel-x86_64-2.6.16-gentoo-r6 with enabled IA32_Emulation, after rebooting emerging of glibc-2.3.6-r3 was successful and my AMD64-box works well. I hope we can close this bug report now. Best regards Stefan Salewski
Well, now I'm getting it on AMD64 when compiling motion. I saw some stuff about config.guess guessing wrong in a thread here: http://sourceware.org/ml/crossgcc/2006-01/msg00182.html uname -a on my system gives: Linux optimator 2.6.16-gentoo-r7 #2 SMP PREEMPT Sat May 27 23:53:08 EDT 2006 x86_64 Dual Core AMD Opteron(tm) Processor 275 GNU/Linux Finally, Here is config.log from the error: checking for linux/videodev.h... yes checking for memmem... no checking for short int... yes checking size of short int... configure: error: cannot compute sizeof (short int), 77 See `config.log' for more details. !!! Please attach the config.log to your bug report: !!! /var/tmp/portage/motion-3.1.19/work/motion-3.1.19/config.log
Created attachment 87742 [details] config.log checking size of short int... configure: error: cannot compute sizeof (short int), 77 See `config.log' for more details.
I also made sure the stuff in Comment 5 was correct in the kernel config. GLIBC on my system is: sys-libs/glibc-2.3.6-r3 [ebuild R ] sys-libs/glibc-2.3.6-r3 -build -erandom -glibc-compat20 -glibc-omitfp -hardened -linuxthreads-tls (-multilib) +nls +nptl -nptlonly -pic -profile (-selinux) +userlocales 0 kB
Yeah, the original issue is probably lack of 32bit support in kernel. Jacob, please open a separate bug for motion as that is unrelated mostly due to a missing dependency.
CONFIG_IA32_EMULATION=y Been there since day one over a year ago.
Ok, made a new Bug 134931
