gcc 3.4.0 and glibc

ralam · 04-25-2004, 07:20 PM

In Chapter 5, when compiling glibc 2.3.3 with the just bootstrapped gcc 3.4.0 and linux headers 2.6.5, I get this error:

I have no overriding environment variables like CFLAGS and CXXFLAGS set. How do I solve this error?

Note you may also need to use the -fno-unit-at-a-time compiler flag. I did.

Code:

make CFLAGS+="-fno-unit-at-a-time"

Ok, I solved the problem by using a more recent version of glibc (2.3.4)

cmcginty · 05-04-2004, 10:53 PM

Hey, exactly where did you get Glibc 2.3.4. I'm looking all over for this and can't seem to find it.

cmcginty · 05-05-2004, 02:11 AM

I am assuming you got it from the glbic CVS on sources.redhat.com. I haven't used CVS very much unfortunately. The version.h file says the current version is 2.3.3, yet looking at the Versions.def file there is a marker for 2.3.4. How can I get a list of tags in the libc module, or find out what date was the official 2.3.4 code?

This is the "all the packages" page for Bleeding Edge Linux From Scratch. Scroll to the bottom of the page and read note 2

cmcginty · 05-05-2004, 06:16 PM

Thanks, I didn't know there was a BE-LFS project. If I'm right, I think the page you were reffering to is this:

Yes, sorry, I didn't realize I'd forgotten to post the link. How stupid of me. My apologies.
