While trying to cross-compile Python-3.9.7, I came across the next error report: i586-cross-linux-gcc -Xlinker -export-dynamic -o python Programs/python.o -L. -lpython3.9 -lcrypt -ldl -lpthread -lm -lm _PYTHON_PROJECT_BASE=/mnt/lfs/sources-base/Python-3.9.7 _PYTHON_HOST_PLATFORM=linux-i586 PYTHONPATH=./Lib _PYTHON_SYSCONFIGDATA_NAME=_sys configdata__linux_i386-linux-gnu python -S -m sysconfig --generate-posix-vars ;\ if test $? -ne 0 ; then \ echo "generate-posix-vars failed" ; \ rm -f ./pybuilddir.txt ; \ exit 1 ; \ fi /bin/sh: line 1: python: command not found generate-posix-vars failed make: *** [Makefile:619: pybuilddir.txt] Error 1 ----------------------------------------------------------- Strange, because Python configure/Makefile known that we are cross-compiling, but still try to execute a program with the target architecture, which is not the same as the architecture of the build machine. Of course it fails. |

Update: I came to realize that the command 'python' is without './', so it will search using PATH for python. Which - on my system Opensuse TW - does not exist, since there we have 'python3'. So, I made a softlink python->python3. Alas, I noticed that when I made the softlink python to python3 before starting configure, configure stops and complains that python3.9 is not found. Sure, TW has python3.8. But why check for previous/current versions, when making a new python binary? Ok, made the link after configure was done, which ended in: ---------------------------------- i586-cross-linux-gcc -Xlinker -export-dynamic -o python Programs/python.o -L. -lpython3.9 -lcrypt -ldl -lpthread -lm -lm _PYTHON_PROJECT_BASE=/mnt/lfs/sources-base/Python-3.9.7 _PYTHON_HOST_PLATFORM=linux-i586 PYTHONPATH=./Lib _PYTHON_SYSCONFIGDATA_NAME=_sysconfigdata__linux_i386-linux-gnu python -S -m sysconfig --generate-posix-vars ;\ if test $? -ne 0 ; then \ echo "generate-posix-vars failed" ; \ rm -f ./pybuilddir.txt ; \ exit 1 ; \ fi Could not import runpy module Traceback (most recent call last): File "/mnt/lfs/sources-base/Python-3.9.7/./Lib/runpy.py", line 14, in <module> import importlib.machinery # importlib first so we can test #15386 via -m File "/mnt/lfs/sources-base/Python-3.9.7/./Lib/importlib/__init__.py", line 57, in <module> import types File "/mnt/lfs/sources-base/Python-3.9.7/./Lib/types.py", line 296, in <module> GenericAlias = type(list[int]) TypeError: 'type' object is not subscriptable generate-posix-vars failed make: *** [Makefile:619: pybuilddir.txt] Error 1 ------------------------------------- Complete native compile functions as expected. Maybe the reason that TW is still using 3.8? Shall try that next. |

Update 2: Using the python-3.8.12 source....no problem! All functions well. So, 3.9 has some issues i guess ;) |
