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

I did rollback my new toolchain to 2.33 and I didn't keep the 2.34 one. :\.
I think it was rather simple, it didn't find the library and I didn't dig
much deeper. I'm not in dire need of 2.34, it was just a maintenance bump.
Maybe something to do with the platform PTXCONF_GLIBC_VERSION?
"Specify the glibc version this BSP shall be built with. This information is
used to guess the toolchain path if you use "ptxdist toolchain" without an
argument, and to install the glibc into the target file"
I can redo the toolchain. Do you have any suggestions?
My guess is, that the heuristics in scripts/install_copy_toolchain.sh
cannot handle the changes in 2.34, but I'm not sure.

Quote from changelog:
* Previously, glibc installed its various shared objects under versioned
file names such as libc-2.33.so. The ABI sonames (e.g., libc.so.6)
were provided as symbolic links. Starting with glibc 2.34, the shared
objects are installed under their ABI sonames directly, without
symbolic links. This increases compatibility with distribution
package managers that delete removed files late during the package
upgrade or downgrade process.
Seems like glibc decided to be a trainwreck from one version to another with
no apparent mean of restoring old behavior for a smoother transition period?
Ptxdist glibc installation fails with this naming scheme. If anyone knows
any better here, please enlighten me.
Right, so PTXdist first tries to find the specified file, e.g. libc.so.6,
and should then follow symlinks and deal with ld.so scripts. I'm not sure
why that fails but it should be possible to fix it to handle new and old
glibc versions.
What's the error that you get?
