Per https://copr.fedorainfracloud.org/coprs/sharkcz/danny/build/8372393/ there is no such problem in earlier releases. It exists in ld.so:
$ readelf -a -W usr/lib64/ld64.so.2 | grep __parse_hwcap
19: 000000000002e240 2516 FUNC GLOBAL DEFAULT [<localentry>: 8] 9 __parse_hwcap_and_convert_at_platform@@GLIBC_2.23
30: 000000000002e240 2516 FUNC GLOBAL DEFAULT [<localentry>: 8] 9 __parse_hwcap_3_4_and_convert_at_platform@@GLIBC_2.39
663: 000000000002e240 2516 FUNC GLOBAL DEFAULT [<localentry>: 8] 9 __parse_hwcap_and_convert_at_platform@@GLIBC_2.23
680: 000000000002e240 2516 FUNC GLOBAL DEFAULT [<localentry>: 8] 9 __parse_hwcap_3_4_and_convert_at_platform@@GLIBC_2.39
And libc.so includes it AS_NDEEDED:
$ cat ./usr/lib64/libc.so
/* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily. */
OUTPUT_FORMAT(elf64-powerpcle)
GROUP ( /lib64/libc.so.6 /usr/lib64/libc_nonshared.a AS_NEEDED ( /lib64/ld64.so.2 ) )
So I would expect the link to resolve the reference to the dynamic loader.
I don't think there is any bug here, but the problem is likely in the link line?
This is likely because libtool tries to reimplement the linker in a shell script. It's required to use the order -lc -lgcc_s -lc (listing -lc twice), otherwise links with -Wl,--as-needed fail. you are right, sounds like bug 2047389 is back FEDORA-2025-1072edb794 (libtool-2.5.4-2.fc42) has been submitted as an update to Fedora 42. https://bodhi.fedoraproject.org/updates/FEDORA-2025-1072edb794 FEDORA-2025-1072edb794 (libtool-2.5.4-2.fc42) has been pushed to the Fedora 42 stable repository. If problem still persists, please make note of it in this bug report. |
