How can I fix the problem with glibc 
Thank you

config Log glibc

This is a config.log after glibc failed to compile.
Comment 2 Jakub Moc (RETIRED) gentoo-dev 2006-06-16 03:16:50 UTC
Check that you have CONFIG_IA32_EMULATION=y in your kernel.

Comment 3 Mudrii 2006-06-16 03:21:01 UTC
I have this option in the kernel 
 
cat /usr/src/linux/.config | grep CONFIG_IA32_EMULATION
CONFIG_IA32_EMULATION=y
Comment 4 Mudrii 2006-06-16 03:25:56 UTC
Before this problem I update to the kernel gcc-3.4.5 and all compiles but not glibc

I have another box with same config only runs gcc-4.1.1 and try to make a binary package and move to the problem PC and same error get again

You're having sandbox problems, so setting FEATURES=-sandbox should work as a workaround for the time being
Comment 6 Mudrii 2006-06-16 20:51:09 UTC
Try to emerge glibc with FEATURES=-sandbox and same error 

checking for long double... yes
checking size of long double... configure: error: cannot compute sizeof (long double), 77

Same problem with emerging sandbox

Some other fixeas > ?
Comment 7 Martin Schlemmer (RETIRED) gentoo-dev 2006-06-17 07:07:52 UTC
Looks like 32bit toolchain is broken or missing (which would explain the sandbox issues as well if 32bit libc is missing).
Comment 8 Mudrii 2006-06-17 17:49:14 UTC
how can be fixed this error ?
Comment 9 Mike Doty (RETIRED) gentoo-dev 2006-06-17 17:53:39 UTC
try resetting your compiler with eselect compiler or gcc-config. then 'source /etc/profile'
Comment 10 Mudrii 2006-06-18 03:33:03 UTC
no work changing the compiler
Comment 11 Mark Anders 2006-06-20 20:04:14 UTC
I had this same problem, but I seem to have fixed it now. I tried compiling a short c++ program: 
 #include <iostream> 
 
 int main() { 
 std::cout << "sizeof(char) = " << sizeof(char) << std::endl; 
 std::cout << "sizeof(short) = " << sizeof(short) << std::endl; 
 std::cout << "sizeof(int) = " << sizeof(int) << std::endl; 
 std::cout << "sizeof(long) = " << sizeof(long) << std::endl; 
 std::cout << "sizeof(long long) = " << sizeof(long long) << std::endl; 
 std::cout << "sizeof(float) = " << sizeof(float) << std::endl; 
 std::cout << "sizeof(double) = " << sizeof(double) << std::endl; 
 std::cout << "sizeof(long double) = " << sizeof(long double) << std::endl; 
 return 0; 
 } 
 
 It ran fine under 64bit mode. Then I recompiled with the -m32 switch. Compilation was fine, but it wouldn't run. I checked and the dynamic linker was set to /lib/ld-linux.so.2 which wasn't there. So I created a symbolic link from that to /lib32/ld-linux.so.2. Now it worked. I'm guessing maybe the compiler was messed up in the specs file which is where the dynamic linker is normally defined. Hope this helps . . .
Comment 12 Mudrii 2006-06-21 09:52:11 UTC
yup
/lib32 was missing from /etc/ld.so.conf

echo "/lib32" >> /etc/ld.so.conf
ldconfig	

fixed the problem

alright
