Linux Specific build notes
--------------------------
Written by Ken Goldman

Prior to the autotools support, most users began by untarring the
tarball or cloning the git repo, and then executing 'make' or 'make -f
<makefile>' in the utils and utils12 directories. For autotools and the
existing makefiles to co-exist, the existing "makefile" was renamed to
"makefiletpmc".
$ cd utils
$ make -f makefiletpmc
$ cd utils12
$ make -f makefiletpmc
This builds a TSS
- with TPM 2.0 and TPM 1.2 support,
- connecting to a TPM 2.0 SW TPM,
- with TSS state files in cwd,
- with tracing support,
- and with elliptic curve support.
Refer to the "Advanced options", below, for additional compiler options.
Autotools - Linux
---------
On Linux (and probably other Unix systems), open source projects expect that
the normal shell command 'autoreconf -i && ./configure && make && make install'
should configure and build the package.
If --prefix is omitted, the default /usr/local is used.
The LD_LIBRARY_PATH environment variable must be set to the path
(either the default or a user specified path). E.g.,
export LD_LIBRARY_PATH=/usr/local/lib
Example 1: To configure the TSS library to use the software TPM, build and
install the package in ${HOME}/local/bin and ${HOME}/local/lib directories
execute the following shell commands:
$ autoreconf -i
$ ./configure --prefix=${HOME}/local --disable-hwtpm
$ make clean
$ make
$ make install
An initial set of the most common TSS "./configure" options are defined
to enable/disable different features.
--disable-tpm-2.0 - include only TPM 1.2 support
--disable-tpm-1.2 - include only TPM 2.0 support
--disable-hwtpm - don't use the hardware TPM, use a software one instead
--disable-rmtpm - when using a hardware TPM, don't use the resource manager
--enable-noprint - build a TSS library without tracing or prints
--enable-nofile - build a TSS library that does not use files to preserve state
--enable-nocrypto - build a TSS library that does not require a crypto library
(dependency on "--enable-nofile")
--enable-noecc - build a TSS library that does not require OpenSSL elliptic curve support
--enable-debug - build a TSS library used for debugging.
Example 2: To configure the TSS library to use the hardware TPM, build and
install the package in the default /usr/local directories requires root
privileges. Executing the following shell commands will make and install the
package in the default directories.
$ autoreconf -i
$ ./configure
$ make clean
$ make
$ sudo make install
Other TSS features can be modified by specifying them directly as CFLAGS
"./configure" options.
CFLAGS='<options>'
options:
-O0 - change compiler optimization (default: 02)
-DTPM_DEVICE_DEFAULT="\"/dev/tpmrm0\"" - change hardware TPM (default: /dev/tpm0)
z-DTPM_DATA_DIR_DEFAULT="\"<pathname>\"" - specify directory for TSS state files
-DTPM_TRACE_LEVEL_DEFAULT="\"<level>"" - change level of tracing (default: 0)
0 - no tracing
1 - trace errors
2 - trace errors and execution flow
Example 3: To install the package in ${HOME}/local/bin and ${HOME}/local/lib
directories, compile for the gdb debugger, and connect by default to a socket
simulator TPM at command port 3333, execute the following shell commands:
$ autoreconf -i
$ ./configure --prefix=${HOME}/local --enable-debug --disable-hwtpm \
CFLAGS='-DTPM_INTERFACE_TYPE_DEFAULT="\"socsim\"" -DTPM_COMMAND_PORT_DEFAULT="\"3333\""'
$ make clean
$ make
$ make install
The TPM utility binaries are stored in utils/.lib and utils12/.lib directories
of the source directory.[1] To debug using these binaries in the source tree,
use either the binary stored in .lib or the libtool command.
$ libtool --mode=execute gdb <.lib/utility>

These are two sets of contributed instructions for a Mac autotools
build. There is also a contributed utils/makefile.mac.

Advanced options
----------------
For all options and details, see the documentation in ibmtss.doc or
ibmtss.html.
Some of the more common options are below.
1-3 can also be specified in an environment variable or at run time.
4-8, which are used to reduce the size of the library, must be
specified at compile time.
1) To default to a hardware TPM (rather than the SW TPM)
Add to CCLFLAGS:
-DTPM_INTERFACE_TYPE_DEFAULT="\"dev\""
2) To default to /dev/tpmrm0 (rather than /dev/tpm0)
Add to CCLFLAGS:
-DTPM_DEVICE_DEFAULT="\"/dev/tpm0\""
3) To default to a different directory for TSS state files (rather
than cwd)
Add to CCLFLAGS:
-DTPM_DATA_DIR_DEFAULT="\"directory\""
4) To remove TPM 1.2 support
Delete from CCLFLAGS and CCAFLAGS
-DTPM_TPM12
5) To remove the requirement for a filesystem (see documentation for
limitations)
Add to CCFLAGS
-DTPM_TSS_NOFILE
6) To remove the requirement for crypto (see documentation for
limitations)
Add to CCFLAGS
-DTPM_TSS_NOCRYPTO
7) To remove print tracing support
Add to CCFLAGS
-DTPM_TSS_NO_PRINT
8) To remove elliptic curve dependencies
Add to CCFLAGS
-DTPM_TSS_NOECC
