Just because the last couple months were quiet doesn’t mean that nothing’s going on. Case in point, the last month of 2021 saw a ton of updates, though many of them had been in the works for a long time.
Yum now requires the ibmi-repos package. This should hopefully mean a smooth transition to the new repos as users update their installations.
If you have more questions please refer to the FAQ or reach out to me.
OpenBLAS has been updated to
0.3.19 which brings
optimized code paths for both POWER9 and Power10. In addition, OpenBLAS will
now determine the proper CPU optimizations and number of cores to use at
runtime automatically instead of having to set
OPENBLAS_NUM_THREADS, respectively. Users can still set these values if they
want to override them.
NOTE: This package is only available for IBM i 7.3 and newer.
Python 3.9 packages for Numpy, Pandas, and other ML packages are now available! This has been a long-awaited update for many users, especially as Python 3.6 is now no longer supported.
In addition, many packages have been updated (including some major version changes) and new dependencies packaged. You’ll definitely want to test your applications.
Full list of packages and versions:
- numpy 1.21.4
- pandas 1.3.4
- scipy 1.7.3
- scikit-learn 1.0.1
- beniget 0.4.1
- gast 0.5.3
- joblib 1.1.0
- ply 3.11
- pybind11 2.8.1
- pythran 0.10.0
- threadpoolctl 3.0.0
NOTE: These packages are only available for IBM i 7.3 and newer.
CMake was updated to 3.16.9 and now builds svr4-style libraries when the
SOVERSION property is set on a library target. The soname will
SOVERSION, unless not specified in which case it uses
and if that is not specified, it builds an un-versioned shared object.
add_library(foo SHARED foo.c) # Creates libfoo.so add_library(bar SHARED bar.c) set_target_properties(bar PROPERTIES SOVERSION 1) # creates libbar.so -> libbar.so.1 add_library(baz SHARED baz.c) set_target_properties(baz PROPERTIES VERSION 1.2.3) # creates libbaz.so -> libbaz.so.1.2.3 add_library(bla SHARED bla.c) set_target_properties(bix PROPERTIES VERSION 1.2.3 SOVERSION 1) # creates libbla.so -> libbla.so.1
This brings CMake in line with libtool’s
--with-aix-soname=svr4 option used
throughout our rpm ecosystem.
GDB has been rebuilt to use NCURSES instead of the PASE curses libraries. This fixes errors when using terminals other than “xterm” or “aixterm” (eg. xterm-256color used by most modern Linux terminals). It also now properly handles UTF-8 locales when running in TUI mode.
The OpenJDK 11 Early Access rpm has been updated to handle the SVR4-style libraries we use in our rpm ecosystem when using dynamic linking. This fixes problems when loading libraries for FreeType, GLib, OpenSSL, CUPS, Fontconfig, libzip, and more.
This package now provides a charset-alias sub-package shipping /QOpenSys/pkgs/lib/charset.alias, which can be used as an rpm dependency for other packages which depend on this file.
TK is now built with the open source X.org X11 libraries instead of the PASE X11 libraries.
The system PKI trust directories (/QOpenSys/etc/pki/trust and /QOpenSys/pkgs/share/pki/trust) changed ownership from the p11-kit package to ca-certificates. Most users will not have the p11-kit package installed in normal operation, which meant that these directories wouldn’t be either. This made it more difficult for users to figure out where to put their own CA certificates (eg. for self-signed certificates). In addition, we’ve added a README file at /QOpenSys/etc/pki/trust/anchors/README. Seiden Group also has a great step-by-step article outlining the steps.
Speaking of CA certificates, the system CA certificate trust store, based on Mozilla’s trust list, has been updated based on the NSS 3.60.
If you’re interested in all the changes:
- NSS 3.45 CA Changes
- NSS 3.46 CA Changes
- NSS 3.48 CA Changes
- NSS 3.54 CA Changes
- NSS 3.57 CA Changes
- NSS 3.60 CA Changes
- python3 was updated to 3.6.15
- python39 was updated to 3.9.8
- service-commander was updated to 0.7.0 and 0.7.2
- libutil has been updated to 0.11.1
- nss updated to 3.68.1
- nspr updated to 4.32
Well, that’s it for 2021. What a year!
We had some big new packages and versions:
- GCC 10
- Node.js 16
- Python 3.9
We also had quite a lot of smaller updates to packages like bash, curl, db2util, nginx, R, etc. What was your favorite update this year?
Check back next week for the start of 2022 updates.
