Build error

[jpaul]

I tried to build the latest repro on CentOS 1804 x64 and got a failure.
cmd issued: sudo /usr/local/bin/python3.7 setup.py install

update

I also tried the 0.14.0 version from here and got a different build error:

Thank you for your detailed report!

On 64-bits Linux, you should use the wheels released to pypi. I think that sudo /usr/local/bin/python3.7 -m pip install python-mbedtls would work in your case.

Otherwise, if you want/need to build python-mbedtls (the python library), you need to install mbedtls (the C library) first. python-mbedtls is not written in pure Python and requires the headers and the shared libraries from mbedtls to compile.

Provided you have a C compiler, curl, and CMake, you can use the shell script available in scripts/install-mbedtls.sh. The script takes the version of mbedtls that you want to install as argument, so run sudo ./scripts/install-mbedtls.sh 2.7.8 from the root of python-mbedtls to download and install mbedtls 2.7.8 to /usr/local.

Once you have mbedtls, install python-mbedtls with python setup.py install.
