glibc 2.3.6 on LFS 5.6
 

Hi there!
i've a problem while i use the command
../glibc-2.3.6/configure --prefix=/tools \
--disable-profile --enable-add-ons \
--enable-kernel=2.6.0 --with-binutils=/tools/bin \
--without-gd --with-headers=/tools/include \
--without-selinux

I've compiled and installed binutils, gcc and libc headers without error same version that's in the man.

This is the log:
[...]

*** versioning will introduce incompatibilities so that old binaries
*** will not run anymore.
*** For versioning you need recent binutils (binutils-2.8.1.0.23 or newer).

See `config.log' for more details.

thanks

Did you look at "config.log" to see why the compiler could not handle a "long double"?

i've found in configure:7509

what can i do?

if i remove --with-binutils=/tools/bin
work...

I've followed the lfs...

after, when i use make

In file included from version.c:33:
/sources/glibc-build/csu/version-info.h:2: error: missing terminating " character
/sources/glibc-build/csu/version-info.h:3: error: missing terminating " character

make: *** [all] Error 2

I do not know. I just wrote a little test program to compute the size of a long double, and it compiled and ran for me using Cygwin. You must have something misconfigured somewhere.

No error if i use LFS's LiveCD...

Thanks David for reply
