Python 3.11 and 3.12 compile packages for ARM64 on an Intel64 Mac resulting in errors

I was never able to install packages like pyzmq, scipy, numpy, and pandas because pip compiles these packages for arm64 instead of x86_64.
I only found out the cause of the error when I ran pip without realizing I had specific flags in my CFLAGS variable for a previous program I was compiling, as before I had just given up not understanding the errors and opted for the pip that came with python3.9 that did not give this error.
clang: error: unsupported option '-mlong-double-64' for target 'arm64-apple-macosx13.1.0' clang: error: the clang compiler does not support '-mtune=skylake
Is there any way to provide the correct target for pip, and what should it be for x86_64 intel OSX / MacOS?

Problems with installing Kivy on MacOS

I tried to install Kivy on my computer but unfortunately I failed.
I'm running MacOS (v10.13.4) and I have installed Cython successfully (v0.26).
I ran:
pip3 install kivy
Then the process starts and the following error occurs:
**Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/yl/kw3svt1x4rdfdjzsd5hds9_c0000gn/T/pip-req-build-869vs3u5/**.
Is it possible to fix it?
As asked in the comments I'm posting the complete error trace:

Detected Cython version 0.26
This version of Cython is untested with Kivy. While this version may
work perfectly fine, it is possible that you may experience issues. If
you do have issues, please downgrade to a supported version. It is
best to use the newest supported version, 0.25.2, but the minimum
supported version is 0.23.
If your platform provides a Cython package, check if you can downgrade
to a supported version. Otherwise, uninstall the platform package and
install Cython via pip:
pip install -I Cython==0.25.2

Install cx_oracle on solaris 11 sparc

Most of the cx_Oracle 5.2.1 version builds are for Windows and Linux. How do I install/get an install for a Solaris 11 Sparc?
I tried to install using the following: cx_Oracle-5.2.1.tar.gz from sourceforge.net
But resulted in the following error:
/tmp/cx_Oracle-5.2.1$ python setup.py build

Please advise.

Oracle (nor Sun, for that matter) did not include a compiler in the Solaris OS installation image. The Solaris Studio compiler is available for download, and of course you can also go the GCC route (UNIX Packages web site offers installable packages of GCC and various libraries needed for dependences for a modest fee.)
The original post is quote old though, and the solution as of now is to simply install the cx_oracle package from the 11.3 or 11.4 IPS.

I do not know the exact reason for the error you are getting. It looks, however, like the "cc" compiler is not installed. You should be able to find that package and install it. Or you will need to adjust your configuration to use gcc instead. This link may help:

Error when Installing Pycurl on OS X

I am trying to install pycurl on OS X Mavericks. I have downloaded and installed the Xcode dev tools to have some compiler. I went into the Xcode preferences and made sure that I have downloaded all the compliers I would need but still getting this error
When I try to install pycurl I get the following errors. Any help would be much appreciated.

Try this:
brew install python
Double check you are using brewed Python:
which python
(Should return something like /usr/local/bin/python)
Install pycurl with pip.
pip install pycurl
I just tested this on Mavericks.

Try specify the ARCHFLAGS env var:
ARCHFLAGS="-arch x86_64" pip install pycurl

What is the best way to setup Django on os X 10.7 Lion?

I am setting up Python and Django on os X 10.7 from a virgin install and Xcode 4.3.
I tried using the default install of Python:
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/
I normally use a Python based package manager called easy_install.
Easy_install seems to not be able to find the compiler.
EDIT: When I tried to install MySQL-python I got this error:

error: Setup script exited with error: command 'llvm-gcc-4.2' failed with exit status 1
Apparently, the system attempts to use the same compiler used to compile the installed Python framework.
For some reason Apple didn't include llvm-gcc-4.2.
Xcode 4.1 used GCC, but with Xcode 4.3 that seems to have changed.
From what I can gather, Apple wants to use Clang as the compiler vs GCC.
So I added to .bash_profile:
cc=clang
I decided I would just recompile Python with clang but first, I needed to install readline.

What the easiest way to install Django on Lion 10.7?

Did you install the command-line tools with Xcode 4.3? They are not installed by default. You can install them by going to the Downloads pane in Xcode 4.3's preferences.

Making it way too hard:
First, make sure you install Xcode (available for free in the Mac App Store). It includes all the build tools that might be necessary to compile certain Python packages.
To get easy_install just download setuptools and follow the instructions for installing on Mac OS X at that link.
Once that's done, you can easy_install virtualenv to get a nice segregated environment to work in.

For the MySQL issue you have to edit the site.cfgfile:
mysql_config = /usr/local/mysql/bin/mysql_config
And then:
$ python setup.py build
$ sudo python setup.py install

Try updating XCode and reinstall all global site-packages. You may also want to try pip instead of easy_install.
You can also try to compile with
export ARCHFLAGS='-arch i386 -arch x86_64'
This solved many of my problems in the past when upgrading OSX versions.
