This file contains instructions to build and install the TSS libraries.

# Dependencies
To build and install the tpm2.0-tss software the following dependencies are
required:
* GNU Autoconf
* GNU Autoconf archive
* GNU Automake
* GNU Libtool
* C compiler
* C Library Development Libraries and Header Files (for pthreads headers)
* pkg-config

The following are dependencies only required when building the test suite.
Most users will not need to install these dependencies:
* cmocka unit test framework

# Building From Source
## Bootstrapping the Build
To configure the tpm2.0-tss source code first run the bootstrap script, which
generates list of source files, and creates the configure script:
```
$ ./bootstrap
```

## Configuring the Build
Then run the configure script, which generates the makefiles:
```
$ ./configure
```

## Compiling the Libraries
Then compile the code using make:
```
$ make -j$(nproc)
```

## Installing the Libraries
Once you've built the tpm2.0-tss software it can be installed with:
```
$ sudo make install
```

This will install the libraries and the resource manager to locations
determined at configure time. See the output of ./configure --help for the
available options. Typically you won't need to do much more than provide an
alternative --prefix option at configure time, and maybe DESTDIR at install
time if you're packaging for a distro.

**NOTE**: It may be necessary to run ldconfig (as root) to update the run-time
bindings before executing a program that links against libsapi or a TCTI
library:
```
$ sudo ldconfig
```
