Linux build

Use CMake.

Short Version:

sudo apt-get update
sudo apt-get install pkg-config build-essential ninja-build cmake libssl-dev clang

OpenSSL

You will need a supported version of OpenSSL installed in order to build the TPM simulator.

Similarly to the Windows build, if you enable SM{2,3,4} algorithms in TpmProfile_Common.h, the build may fail because of missing SM{2,3,4}.h headers. In this case you will need to manually copy them over from OpenSSL's include/crypt folder.

Cross-Compiling for Big-Endian Architectures

NOTE: These intructions are not optimized, they are the notes of one successful attempt at cross-compiling for ppc64.

REMINDER: Set BIG_ENDIAN_TPM to YES in TpmProfile_Common.h!

REMINDER: NVChip is not compatible between different endiannesses of the TPM. Delete NVChip if it's left over from a previous test.

You can use cmake's cross-compilation features to generate a 64-bit PowerPC binary TPM simulator for testing, even from a little-endian-architecture Linux environment.

You will need the following packages:

  • gcc-powerpc64-linux-gnu
  • binutils-powerpc64-linux-gnu
  • libssl-dev (ppc64)
    • You can build this from openssl source with CROSS_COMPILE=powerpc64-linux-gnu- ./Configure linux-ppc64, then
      • running make / make install
    • If you build and install openssl from source for cross-compilation, it is
      • recommended to specify --prefix=/usr/local/ssl/ppc64/ and
      • --openssldir=/usr/local/ssl/ppc64/ to ensure it does not
      • interfere with any other installations of openssl. See OpenSSL Installation for more
      • information about building and installing OpenSSL from source.
  • libc (ppc64)

    • You can build this from glibc source with:

      configure CC=powerpc64-linux-gnu-gcc CXX=powerpc64-linux-gnu-g++ --target=powerpc64-linux-gnu --host=powerpc64-linux-gnu
make -j
make install

NOTE: The rest of these instructions assume that the PowerPC64 version of openssl got installed at /usr/local/ssl/ppc64/.

Run the binary using qemu-ppc64-static ./Simulator/src/tpm2-simulator. Problems you may run into:

  • You may need to add the path to the PowerPC64 OpenSSL lib directory to LD_LIBRARY_PATH.
  • You may need to add a symlink to your PowerPC64 libc at /lib64/ld64.so.1
