Hi.
I need to revisit the glibc-2.34 naming changes.
Afaiu, no changes has been made regarding this topic.
So, 2022.01 is still not glibc-2.34 compatible?
glibc.make seems to get to libpthread. Ie, it completes these:
ifdef PTXCONF_GLIBC_LD
@$(call install_copy_toolchain_dl, glibc)
endif
ifdef PTXCONF_GLIBC_C
@$(call install_copy_toolchain_lib, glibc, libc.so.6)
endif
...
So it finds ld-linux-x86-64.so.2 and libc.so.6, files without any softlinks.
but:
ifdef PTXCONF_GLIBC_PTHREAD
@$(call install_copy_toolchain_lib, glibc, libpthread.so)
endif
fails, because it's named:
sysroot/lib64/libpthread.so.0 without any other softlinks.
...
lib -
<snip>x-tools/x86_64-secplatform-linux-gnu/x86_64-secplatform-linux-gnu/sysroot/lib64/ld-linux-x86-64.so.2
lib -
<snip>/x-tools/x86_64-secplatform-linux-gnu/x86_64-secplatform-linux-gnu/sysroot/lib64/libc.so.6
install_copy_toolchain_lib: libpthread.so not found
make: *** [<snip>/lib/ptxdist-2022.01.0/rules/glibc.make:38:
<snip>bin/platform-secplatform-x86_64/state/glibc.targetinstall] Error 1
