The first being that Android- NDK has pretty clean And documented integration now with autoconf projects, so it's pretty simple to build the: - tss2-sys - tss2-tcti-* - tss2-tctildr - tss2-mu - tss2-rc Libraries by following the section on autoconf: https://developer.android.com/ndk/guides/other_build_systems#autoconf Then configuring the project like so: ./configure --host=$TARGET --disable-esys --disable-fapi make -j$(nproc) <snip> CCLD libutil.la CCLD src/tss2-mu/libtss2-mu.la CCLD src/tss2-tcti/libtss2-tctildr.la CCLD src/tss2-rc/libtss2-rc.la CCLD src/tss2-tcti/libtss2-tcti-device.la CCLD src/tss2-tcti/libtss2-tcti-swtpm.la CCLD src/tss2-tcti/libtss2-tcti-pcap.la CCLD src/tss2-tcti/libtss2-tcti-mssim.la CCLD src/tss2-tcti/libtss2-tcti-cmd.la CCLD src/tss2-sys/libtss2-sys.la readelf -h ./src/tss2-sys/.libs/libtss2-sys.so | grep -i Machine Machine: AArch64 You can download the NDK from here: https://developer.android.com/ndk/downloads It get's tricky in that in order to use the ESYS or FAPI libraries, you need to satisfy the openssl dependency. For Android in-tree, they have Boring OSSL and are carrying patches on our project for integrating with Boring SSL. For mainline, you can build OSSL against the NDK and then configure tpm2-tss project using normal autoconf idioms to use that OSSL: https://wiki.openssl.org/index.php/Android You would set CFLAGS and LDFLAGS to point to the needed include dirs and library paths for OSSL, something Like what is mentioned in the " Install the OpenSSL Library" and " Compile and Link against the Library" in The aforementioned OpenSSL Android instructions link. > -----Original Message----- > From: Roberts, William C > Sent: Monday, December 28, 2020 1:19 PM > To: Phani Srinivas <phani.srinivas(a)in.abb.com&gt;; Fuchs, Andreas > <andreas.fuchs(a)sit.fraunhofer.de&gt;; tpm2(a)lists.01.org > Subject: RE: TPM2 TSS on Android > > The example Andreas shows is built using a "Blueprint" file.
