The Make and CMake build systems create three libraries: libmbedcrypto, libmbedx509, and libmbedtls. Note that libmbedtls depends on libmbedx509 and libmbedcrypto, and libmbedx509 depends on libmbedcrypto. As a result, some linkers will expect flags to be in a specific order, for example the GNU linker wants `-lmbedtls -lmbedx509 -lmbedcrypto`. Also, when loading shared libraries using dlopen(), you'll need to load libmbedcrypto first, then libmbedx509, before you can load libmbedtls.

### Getting files form git: the Crypto submodule
The Mbed Crypto library now has its own git repository, which the Mbed TLS build systems are using as a git submodule in order to build libmbedcrypto as a subproject of Mbed TLS. When cloning the Mbed TLS repository, you need to make sure you're getting the submodule as well:
git clone --recursive https://github.com/ARMmbed/mbedtls.git
Alternatively, if you already have an existing clone of the Mbed TLS
repository, you can initialise and update the submodule with:
git submodule update --init crypto
After these steps, your clone is now ready for building the libraries as detailed in the following sections.
Note that building libmbedcrypto as a subproject of Mbed TLS does not enable the PSA-specific tests and utility programs. To use these programs, build Mbed Crypto as a standalone project.
Please note that for now, Mbed TLS can only use versions of libmbedcrypto that were built as a subproject of Mbed TLS, not versions that were built standalone from the Mbed Crypto repository. This restriction will be removed in the future.
### Make ### Make
We require GNU Make. To build the library and the sample programs, GNU Make and a C compiler are sufficient. Some of the more advanced build targets require some Unix/Linux tools.
