Hi all,

bash-5.2$ oslevel -s
7200-04-01-1939

We build a pyinstaller binary, the python script makes use of logging and pyzmq 27.1.0

The issue is the binary built on 7.2 core dumps on 7.3 bash-5.2# Invalid argument (src/io_thread.cpp:68)

I was suggested by the folks at pyinstaller to use -D_THREAD_SAFE, -D_THREAD_SAFE_ERRNO but the result is same.

Below is the pyinstaller ticket link with sample code used to produce the error/issue.

Hi,

We need more details, for example, what CFLAGS and CXXFLAGS you had used to build, and so on. In AIX, Python modules are recommended to be built in 64-bit mode, though you can also build in 32 bit mode.

Can you try like this?

pip3.12 cache purge

export CXX="g++ -pthread"
export CXXFLAGS=-maix64
export OBJECT_MODE=64
export LDFLAGS="-maix64"
export CC="gcc -pthread"
export CFLAGS=-maix64
pip3.12 install pyinstaller 

And then try??

Note: if you use Python 3.11, then change all commands to pip3.11. We also want to know which Python 3.11 are you using?
Also a common mistake that most make is using the AIX-based Python instead of the toolbox Python. 

So there could be a variety of reasons for not working. We need more details.

Hi,

OBJECT_MODE=64

AR=ar -X64

(venv) bash-5.2$ pip list
Package                   Version
------------------------- -------
altgraph                  0.17.4
packaging                 25.0
pip                       22.3.1
pyinstaller               6.15.0
pyinstaller-hooks-contrib 2025.9
pyzmq                     27.1.0
setuptools                65.5.0
(venv) bash-5.2$ python --version
Python 3.11.3

Python 3.11.3 is built by us, we use pyenv to maintain multiple python versions.

For pyinstaller I did the below:

bash-5.2$ /opt/IBM/xlC/16.1.0/bin/xlclang --version
IBM XL C/C++ for AIX, V16.1.0  (5725-C72, 5765-J12)
Version: 16.01.0000.0021

CC=/opt/IBM/xlC/16.1.0/bin/xlclang

CXX=/opt/IBM/xlC/16.1.0/bin/xlclang++

pip download -d venv/ pyinstaller==6.15.0

then did export CFLAGS="-D_THREAD_SAFE, -D_THREAD_SAFE_ERRNO" as suggested by pyinstaller folks

cd pyinst_debug/7_3/venv/pyinstaller-6.15.0

bootloader/waf distclean all -vv

For pyzmq the below is changed

 export CXX="/opt/freeware/bin/g++"
 export CFLAGS="-maix64 -pthread -fPIC"
 export CXXFLAGS="-maix64 -pthread -fPIC" 

export AR="ar -X64"

export ORIG_PATH=$PATH

export PATH=$PATH:/opt/freeware/bin  
export LDFLAGS="-Wl,-bnoipath /opt/pyenv/versions/3.11.3/lib/libpython3.11.so"  
$PIP_CMD install pyzmq==27.1.0 --no-binary pyzmq --no-cache-dir
export LDFLAGS=""
export PATH=$ORIG_PATH

gcc is version 10

We use the same steps on AIX 7.3 except for setting CFLAGS before pyinstaller

Even the python pyenv is copied and pasted on the AIX 7.3 setup from the 7.2 and the binary works without issues.

libzmq is downloaded from opensource toolbox

To reproduce the issue you can copy the code I shared in the pyinstaller ticket and run the pub code which connects to pyinstaller binary, it needs to be run multiple times for the core dump to occur

sometimes close to 30 hours.
