-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi
Ok, I have reinstated mention of this on my tweaks page. Hopefully this might assist in stopping many people from building systems with broken glibc's. To reiterate the problem:- * if your Ch 5 gcc build says "checking assembler hidden support... no" then your glibc is broken. (the glibc function __cxa_atexit will not work properly - run glibc's make check and watch tstcxaatexit fail) * if the binutils version on your *host* system is 2.12.1 or greater then you should be ok - "checking assembler hidden support... yes" * using the HAVE_GAS_HIDDEN thing even if it does say "yes" is completely harmless (we end up with HAVE_GAS_HIDDEN defined twice - big deal!) * now that we are passing --enable-__cxa_atexit for gcc, it is vitally important that our __cxa_atexit function in glibc actually works. * if anyone has built a broken glibc then you can possibly get away with just rebuilding glibc with the dynamic gcc again in Ch 6 * I still maintain that the LFS build method is potentially flawed. The *only* thing we build with our static Ch 5 gcc is glibc, the most important lib on the system! The only proper solution in my mind is to build glibc twice in Chapter 6 - at the start and at the end. Greg and further: > Is the option --enable-__cxa_atexit for gcc in chapter 5 & 6 ok ? > or should I pass this option only in chapter 6 ? It only affects C++. We don't build a C++ compiler in Ch 5 therefore there is no need to supply the switch in Ch 5. > should I append "#define HAVE_GAS_HIDDEN 1" to > gcc-build/gcc/auto-host.h in chapter 5 ? Yes, only in Ch 5. No need in Ch 6. so, go read the LFS book about installing gcc and glibc and make use of these notes. - -- Unsubscribe: send email to [EMAIL PROTECTED] and put 'unsubscribe lfs-dev' in the subject header of the message -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE9i/mlSrrWWknCnMIRApnRAJ9zHz+//G3itDDehymIsy8JQ3/kRACgpKfs S/vAK3YdvPNg8KRcVYBVdpw= =bOzu -----END PGP SIGNATURE----- _______________________________________________ Linux-users mailing list [EMAIL PROTECTED] Unsubscribe/Suspend/Etc -> http://www.linux-sxs.org/mailman/listinfo/linux-users
