Error while trying to install odoo15 requirements.txt on M1

I am trying to install the requirements for odoo15 on my MBP M1 Pro running MacOS Ventura 13.0 in my virtual environment running python 3.10.8
but I keep getting the following error:
build/temp.macosx-12-arm64-cpython-310/_openssl.c:575:10: fatal error: 'openssl/opensslv.h' file not found

Now, I have already spent a lot of time researching and it seems that openssl might be the problem here
I have already install openssl via brew, it is running the newest version, as suggested in this GitHub issue
I have installed the newest version of pip as suggested in this StackOverflow post
Edit: I have now also tried setting these flags as suggested in this StackOverflow post:
export LDFLAGS="-L/opt/homebrew/opt/openssl#1.1/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl#1.1/include"
I have also retried everything in another venv using Python version 3.8

So how can i install lxml lib? I've tried pip, but there is the same finish.

Try to install the following packages:
sudo apt-get install libxml2-dev libxslt1-dev python-dev
If this does not work, make sure that it is not a problem of memory, if so you will need to increase your machine memory.

Just had to add more memory to the instance in order to finish the lxml compilation

Error installing bcrypt with pip on Cygwin: cant find ffi.h (libffi is installed)

Similar to this question, I'm having trouble installing bcrypt under Cygwin, and receiving this error:
Downloading/unpacking bcrypt
Downloading bcrypt-1.0.2.tar.gz (40kB): 40kB downloaded
Running setup.py (path:/tmp/pip_build_Chris/bcrypt/setup.py) egg_info for package bcrypt
c/_cffi_backend.c:13:17: fatal error: ffi.h: No such file or directory
#include <ffi.h>
^
compilation terminated.
...
distutils.errors.DistutilsError: Setup script exited with error: command 'gcc' failed with exit status 1
Complete output from command python setup.py egg_info:
c/_cffi_backend.c:13:17: fatal error: ffi.h: No such file or directory
#include <ffi.h>
^
compilation terminated.
The libffi-devel package is installed, and I've also tried using the --global-option='-I/lib/libffi-3.0.13/include' argument to tell pip exactly where the ffi.h file is on my system.

I was able to build/install this implementation from source under Cygwin: https://bitbucket.org/alexandrul/py-bcrypt/overview

I met the same problem.
Fixed the problem by:
cp /usr/lib/libffi-3.0.13/include/*.h /usr/include

Installing M2Crypto on CentOS

I am trying to install M2Crypto on CentOS by compiling from the source.
i am doing a python setup.py build
But I get the following error,

The following should work:
env SWIG_FEATURES="-cpperraswarn -includeall -D__`uname -m`__ -I/usr/include/openssl" python setup.py build
Edit: and openssl-devel package is of course also required.

I just had this problem. In M2Crypto's INSTALL file:
Note about Fedora Core -based Distributions
----------------------------------------------------
Fedora Core (and RedHat, CentOS etc.) have made changes to OpenSSL
configuration compared to many other Linux distributions. If you can not
build M2Crypto normally, try the fedora_setup.sh script included with
M2Crypto sources.
My solution was to get the sources from PyPI or from the source. Then in the M2Crypto directory:
$ chmod +x fedora_setup.py
$ ./fedora_setup.py install
If you're using a virtualenv, change the path of the python interpreter in that file, or activate your environment before building.
The only dependency that I had that wasn't satisfied on my system was openssl-devel.

Install openssl-devel.

Follow Brian's instruction, and make sure you have install openssl-devel. if you experience error like this:
./fedora_setup.sh build
running build
running build_py
running build_ext
building 'M2Crypto.__m2crypto' extension
swigging SWIG/_m2crypto.i to SWIG/_m2crypto_wrap.c

SWIG/_ec.i:7: Error: Unable to find 'openssl/opensslconf-i686.h'

You are running i386 operating system on 64 bit hardware. arch =´uname -m´ will yields i686. The easiest way is to work around this is to create a symbolic link.
sudo ln -s /usr/include/openssl/opensslconf-i386.h /usr/include/openssl/opensslconf-i686.h
Or if you experience errors like:
./fedora_setup.sh build
running build
running build_py
running build_ext

Some headers are missing, just issue the following command and try again:
sudo yum install python-devel

I had this problem now (in 2018), I solved it by installing openssl-devel, gcc and make
yum install gcc gcc-c++ make openssl-devel
