Hello Folks,

i have a problem installing Python module orjson on AIX 7.3.

I get following error message:

I am using Python 3.11 but it does not work with Python 3.9 also

Any ideas?

kind regards

Some discussion regarding this.  https://github.com/rust-lang/rust/issues/94232 . We will involve rust compiler team for further debugging. 

But for time being, can you follow below steps and try it in your system. Suggested patch is disabing  lto in Cargo.toml.

  • git clone https://github.com/ijl/orjson.git

  • git checkout 3.10.12

  • Apply below patch. 

    diff --git a/Cargo.toml b/Cargo.toml

    index 4a6213e..9ed7037 100644

    --- a/Cargo.toml

    +++ b/Cargo.toml

     incremental = false

    -lto = "thin"

    +lto = "off"

     opt-level = 3

     panic = "abort"

  • python3 -m pip install . --root $PWD/install -v

    In above command, change the value of '--root' as per your need.
