glibc-2.39-r6 |configuration not matched in ../abi-

[Administrator note: this post, and the first 4 responses, were originally attached to the solved topic [Solved] glibc-2.39-r6 |configuration not matched in ../abi-. This poster has a different problem, so I split it out. The split out post had no title, so I added one. -Hu]

I get the same error "glibc cannot be compiled without optimization" even though i have set "-O2" in my flags:

Is there another setting i need to tweak to get optimization going?

As stated above, i have "-O2" in my CFLAGS (and CXXFLAGS) as well as he arch as returned by resolve-march-native.

Post by Hu » Tue Jun 11, 2024 11:57 am

OP's problem was solved by adding -O2. Yours is not. This suggests you have a different triggering condition leading to the same error message. The output you provided does not appear to me to be sufficient to debug your problem. I see you posted emerge --info above. Please also follow the other instructions Portage prints when a build fails.

# Sam James <sam@gentoo.org> (2023-12-14)
# Gentoo's kernel maintainers have decided to discontinue gentoo-sources and
# gentoo-kernel for old kernel LTS branches because of the resources to require
# testing and patching them, combined with changing kernel lifecycles.
#
# The new policy is to support kernels with genpatches for 3 years after their
# release.
#
# Specifically, 4.14/4.19/5.4 have been dropped. See https://www.mpagano.com/blog/?p=315
# and http://www.kroah.com/log/blog/2018/08/24/what-stable-kernel-should-i-use/.
#
# sys-kernel/vanilla-sources will continue to be provided for all branches
# until they reach formal upstream EOL.

I put the build log in https://pastebin.com/shsN5yVQ

How did the CFLAGS change between emerge --info and the build log? Is there some local override in the environment or package.env or /etc/portage/env?

Code: Select all

 * Running do_src_configure for ABI amd64
 * ==== glibc build environment ========================================================
 *          CFLAGS:   -fno-builtin-strlen
 *        CPPFLAGS:   
 *        CXXFLAGS:   -march=skylake-avx512 -O2 -pipe
 * =====================================================================================

This does not happen on my systems. Try to find where this -fno-builtin-strlen comes from.

I have a similar problem on my system ...

Code: Select all

emerge --info
  ...
 CFLAGS="-march=skylake -O2 -pipe"
 CXXFLAGS="-march=skylake -O2 -pipe"

Code: Select all

* ==== glibc build environment ========================================================
 *          CFLAGS:   -fno-builtin-strlen -g
 *        CPPFLAGS:   
 *        CXXFLAGS:   -march=skylake -O2 -pipe -g

It looks like the override comes from the portage settings

Code: Select all

grep -r CFLAGS /etc/portage
/etc/portage/env/no-builtin-strlen.conf:CFLAGS= -fno-builtin-strlen
/etc/portage/env/debug.conf:CFLAGS="${CFLAGS} -g"
/etc/portage/make.conf:CFLAGS="${COMMON_FLAGS}"
/etc/portage/make.conf:FCFLAGS="${COMMON_FLAGS}"

but I don't know what causes those settings being applied for the glibc build

Not sure where this bad advice comes from as it is both removing make.conf settings, because there is no $CFLAGS pulled in, and is rather dangerous particularly for glibc which is the source of strlen. I would remove this file or at least move it out of /etc/portage/env.

It would be nice to see the result of grep -r . /etc/portage/package.env in this case.

Edit: A quick search of the wiki indicates that valgrind may be in play for the flag. But if you are not actively debugging with valgrind, it is completely unnecessary. Plus, the implementation shown in this file is broken compared to what the wiki shows.

Actually, I found it now ...

Code: Select all

cat /etc/portage/package.env/glibc 
# Store debug info before ELF striping for later use by various debuggers.
# Added for Valgrind which needs glibc debug symbols.
#
sys-libs/glibc no-builtin-strlen.conf debug.conf
