Getting requirements to build wheel did not run successfully

[eddpascoal]

Hi,
when I try to install on

• ubuntu 22
• 64bit
• python 3.10
• poetry or pip

I would get the following error:

Collecting ifxpy==3.0.5
  Downloading IfxPy-3.0.5.tar.gz (155 kB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.

Am I missing something here?

Build it from source:

Informix CSDK needs to be installed somewhere in your system:

informix@lxhost:~/OpenInformix$ echo $INFORMIXDIR
