Question: static link tpm2-tss

[ChuanDou2021]

The version of tpm2-tss I am using is 3.2. x, and the application uses static linking to link tpm2-tss. The statically linked libraries include:

• libtss2-sys.a
• libtss2-esys.a
• libtss2-tctildr.a
• libtss2-mu.a
• libtss2-tcti-mssim.a
• libtss2-tcti-device.a
• libtss2-fapi.a
• libtss2-rc.a

But for the tss runtime, still look for the dynamic link library: libtss2-tcti-device.so, and the log is as follows

debug:tcti:src/tss2-tcti/tctildr.c:159:tctildr_conf_parse() name_conf: "device:/dev/tpmrm0"

Is there a way to achieve pure static linking? thank you

Have you had a look at the configure option --enable-nodl? This might be what you are searching for.
