Error when installing Cython for use with Buildozer - macos

I've run into an error while installing Kivy, which told me to install Cython, so I did.
Except I run into an error, I've tried installing with pip,easy_install, manually but it results in the same. I also tried installing a older version of Cython but no luck.
Error message:
Command /usr/bin/python -c "import setuptools, tokenize;file='/private/tmp/pip_build_root/Cython/setup.py';exec(compile(getattr(tokenize, 'open', open)(file).read().replace('\r\n', '\n'), file, 'exec'))" install --record /tmp/pip-nXMqSR-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/Cython
Storing debug log for failure in /Users/jorn/Library/Logs/pip.log
When I install manually I get this error:

unable to execute clang: No such file or directory
error: command 'clang' failed with exit status 1
I have read and tried all solutions I could find but none work..
I'm running on Mac osx 10.8.5

Ok, thanks to what #RaynP just said about it being a osx/clang issue I found the solution:

The error is related to Xcode 5.1.
You will have to download the cython-master from GitHub. Installing with pip will not work and results in another error.
in terminal go to the cython-master file and enter: sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future python setup.py install
This is a workaround the error.
Now I have installed Cython and can finally compile my app with Kivy/Buildozer:D

"cannot find -lssl; cannot find -lcrypto" when installing mysql-python?

I'm struggling to install the mysql-python pip either systemwide or in a venv on Ubuntu 14.04 with MariaDB 10 installed. Also tried with MariaDB 5.5 and getting the same error. I don't have this issue with vanilla mysql-server installed.
I have the following installed via apt-get:
build-essential
python-dev
libmariadbclient-dev (thats the MariaDB replacement for libmysqlclient-dev)
python-mysqldb
Originally I thought this was an issue installing this into a venv but I've subsequently noticed mysql-python won't install systemwide either. Below are the cmds I used to install in a venv.
virtualenv venv
. venv/bin/activate
pip install mysql-python==1.2.5

You need to have installed the development libraries of OpenSSL. It can be a libssl-dev, libssl-devel if your distribution provides separated packages for the dev libraries. Or install the complete openssl package if they don't.

But, there were two messages that you have that I didn't, namely:
/usr/bin/ld: cannot find -lssl
/usr/bin/ld: cannot find -lcrypto
Which if you did ld -lcrypto --verbose or ld -lssl --verbose wouldn't produce this results:
➜ src ld -lcrypto --verbose | grep succeeded
attempt to open //usr/lib/x86_64-linux-gnu/libcrypto.so succeeded
ld: warning: cannot find entry symbol _start; not setting start address
➜ src ld -lssl --verbose | grep succeeded
attempt to open //usr/lib/x86_64-linux-gnu/libssl.so succeeded
ld: warning: cannot find entry symbol _start; not setting start address
So, to fix this just make sure you have installed the libssl-dev package which provides both libraries.
I meet the similar error on MacOS but there is no "/usr/bin/ld: cannot find -lssl" for me.
Solved with the following steps:
Step 1. Make sure you have installed openssl with homebrew.
brew install openssl
Step 2. In a terminal:
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
For Linux you can also try yum install your missing library and add them to LIBRARY_PATH.
For Debian 9.x:
apt install libssl-dev
For CentOS:
sudo yum install openssl-devel

So how to fix it and can some one let me know why it is throwing me an error on my new macbook air ?
I suggest you try Pillow, the fork of PIL. I've not tried in a virtual machine but on Mac OS X you can do this:
brew install libtiff libjpeg webp little-cms2
pip install Pillow

I have installed xcode and xcode command line tools.
In fact, I can confirm that cc is installed by executing:
cc -v
which returns:
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix
These flags ended up letting me install it:
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
and then (of course):
sudo -E pip install pandas
Thanks #user3378649 for the flags suggestion - that got me thinking along the right track!
Can you please these commands for more information.
As long as you didn't mention what you used to overcome this problem, I'd suggest different approaches to help narrow down in order to find the problem:
First Solution :
Run these flags :
export ARCHFLAGS="-Wno-error=unused-command-line-argument-hard-error-in-future"
if it doesn't work
run these flags :
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
Second Solution :
Get Homebrew - it's a one-line shell script to install!
Edit your .profile, or whatever is appropriate, and put /usr/local/bin at the start of -your PATH so that Homebrew binaries are found before system binaries
brew install python - this installs a newer version of python in /usr/local
run "pip install pandas"
Third Solution :
use easy_install.
Execute the following command in Terminal
PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:$(PATH)}"
export PATH
Then :
$ sudo easy_install pandas
