I know there are some alternatives to freeze, but I have to maintain a larger project as CGI script which is (for me) not so easy to transform and I use it up to 20 years now.\n\n```\n$ python3 --version\nPython 3.12.2\n$ dpkg -l | grep python3.12\nii  python3.12                           3.12.2-1                                amd64        Interactive high-level object-oriented language (version 3.12)\n...\n$ cat helloworld.py\n#!/usr/bin/python3\n\nprint(\"Hello, World!\")\n$ /usr/share/doc/python3.12/examples/freeze/freeze.py -o frozen helloworld.py\n...\n$ cd frozen\n$ make\n...\nx86_64-linux-gnu-gcc -Wl,-Bsymbolic-functions     -g -fwrapv -O2  -Xlinker -expo\nrt-dynamic -Wl,-O1 -Wl,-Bsymbolic-functions config.o frozen.o M___future__.o M__\n_main__.o  ...\nM_zipp.o /usr/lib/x86_64-linux-gnu/libpython3.12.so   -lm      -lm   -lz -lm -lm   -lexpat  -lexpat     Modules/_hacl/libHacl_Hash_SHA2.a         -lz                        -ldl -lm  -o helloworld\n/usr/bin/ld: cannot find Modules/_hacl/libHacl_Hash_SHA2.a: No such file or directory\ncollect2: error: ld returned 1 exit status\nmake: *** [Makefile:1236: helloworld] Error 1\n```\n\nThe linker does not find the library `Modules/_hacl/libHacl_Hash_SHA2.a` . As far I can see, Ubuntu does not deliver `Modules/_hacl/libHacl_Hash_SHA2.a` as a binary anywhere in the system or as another deb-package. \n\nThe only option I see so far is to compile the python sources myself and copy/link the static Modules folder to the current directory. The following Dockerfile shows that (after removing `RUN` and changing `WORKDIR` to `cd` it should be also runable as shell script). However, this is very unhandy and runs \u003e 1h on my machine.\n\n```\nFROM docker.io/library/ubuntu:noble\n\n# enable package sources\nRUN sed -i '/deb-src/s/^# //' /etc/apt/sources.list \u0026\u0026 apt-get update\n\n# Ubuntu cloud images do not install all files from packages. This drops, e.g.,\n# the Python examples; therefore, remove the Ubuntu cloud \"excludes\" configuration.\nRUN rm -f /etc/dpkg/dpkg.cfg.d/excludes\n\n# install required packages\nRUN apt-get --yes install build-essential python3.12-dev python3.12-examples\n\n# build python\nRUN apt-get --yes build-dep python3.12\nRUN mkdir /build /demo /demo/frozen\nWORKDIR /build\nRUN apt-get --yes source python3.12\nWORKDIR /build/python3.12-3.12.2\nRUN DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage --no-sign -b -j16\n\n# create python demo program\nWORKDIR /demo\nRUN echo '#!/usr/bin/python3\\nprint(\"Hello, World!\")' \u003ehelloworld.py\n\n# run freeze\nRUN /usr/share/doc/python3.12/examples/freeze/freeze.py -o frozen helloworld.py\n\n# add required link to static modules\nRUN ln -s /build/python3.12-3.12.2/build-static/Modules /demo/frozen/Modules\n\n# build and run frozen demo program\nWORKDIR /demo/frozen\nRUN make \u0026\u0026 ./helloworld\n```\n\nWhy is the Hacl library statically linked? Is linking to it necessary at all? Would it be an option to have it as .so as I am used e.g. from psycopg? If needed, in any case it should be provided as binary by the distro. Further, the by freeze generated `frozen/Makefile` (see [Makefile.txt](https://github.com/python/cpython/files/14433051/Makefile.txt)) is full of `$(sourcedir)` referencing the python source directory (after a build), e.g., `LIBHACL_SHA2_A=Modules/_hacl/libHacl_Hash_SHA2.a`. freeze should generate paths as (then) the lib is located by the linux distro.\n\nWith Python 3.11.x everythings works like a charm. Should Ubuntu deliver the Module _hacl as binary, or which form? I cannot find any hint in the system and in the package repo. If desired, I could open a respective issue in Ubuntu Lauchpad bugtracker.\n\nMany thanks for looking into it,\nChris\n\n\n### CPython versions tested on:\n\n3.12\n\n### Operating systems tested on:\n\nLinux\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-119320\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/chris21k","@type":"Person","name":"chris21k"},"datePublished":"2024-02-28T12:15:24.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/116043/cpython/issues/116043"}
