Inkscape and OpenShot throw error "undefined symbol: ssyrk_64_" from libcblas

[Khris777]

Description

I did a fresh install of OpenShot and Inkscape this weekend.
I'm using EndeavorOS and the arch repositories with the pacman package manager.

Both applications fail to start and throw the same error:

Inkscape:
symbol lookup error: /usr/lib/libcblas.so.3: undefined symbol: ssyrk_64_

OpenShot:
ImportError: /usr/lib/libcblas.so.3: undefined symbol: ssyrk_64_

The cblas library just got updated to 3.12.0, so I presume that might be the cause.

cblas Version: 3.12.0
Operating System / Distro: EndeavorOS, Kernel 6.1.62-1-lts

Checklist

• I've included a minimal example to reproduce the issue
• I'd be willing to make a PR to solve this issue

The _64_ in the symbol name suggests that your applications require an "INTERFACE64=ON" build of BLAS/CBLAS. it is possible that the symbol suffix naming has changed from previous releases (new name may be ssyrk64_ or ssyrk_64 as a side effect of providing both normal and extended-address-range symbols in the same library).In that case the 3.12 library would no longer be a drop-in replacement for earlier versions but require a recompile/relink of dependent applications. Can you check with "nm" what the symbol names are in the new Arch build ? (see #666 for background)

I am not knowledgable about nm, but when I use it on libcblas.so(.3(.11.0)) I get "no symbols".
Can you direct me to the correct file I need to look at?

There's also something about the 64-bit API in the release notes.

The "no symbols" is a bit strange for a shared library, perhaps you looked at a symbolic link that is not pointing anywhere
after the update of libcblas to 3.12.0 ?
Make sure that your "blas" package also got updated to 3.12, and if the problem persists perhaps check with whoever manages the lapack/cblas package on the Arch Linux side - I just did a test build of 3.12 on Linux and my nm output looks correct -

nm lib/libcblas.so|grep ssyrk
000000000000d8a0 T cblas_ssyrk
000000000001d8c0 T cblas_ssyrk_64
                 U ssyrk_
                 U ssyrk_64_

(and libblas.so has the matching symbols for ssyrk that libcblas Uses:

nm lib/libblas.so|grep ssyrk
000000000000dff0 T ssyrk_
000000000007ec80 T ssyrk_64_

That was the problem, thanks, I didn't even look at blas as I believed there was automated dependency and version checking to prevent something like this.. The maintainer updated cblas a few days before blas, as of today both are at 3.12 and everything works again.

In case this is useful to anyone finding this, I had the same exact error because I had an old /usr/local/lib64/libblas.so* ... I was confused because nm /usr/lib/libcblas.so.3.12.0 also returned "no symbols", but it works anyway after deleting the old library files.
