make: *** [Makefile:5497: Simulator/src/tpm2_simulator-TcpServer.o] Error 1

Fix this in your source. I have fixed myself this locally, built and generated tpm2-simulator by running make install-exec

when running this executable,

root@host:/usr/local/bin# ./tpm2-simulator
LIBRARY_COMPATIBILITY_CHECK is ON
TPM command server listening on port 2321
Platform server listening on port 2322

My question here is, as it is Linux machine and running this simulator on linux, will this simulator create /dev/tpm0 and /dev/tpmrm0 files to run and work with tpm2 commands??

I don't see these files created. How is this simulator working and how to confirm this??

in one terminal I have run this executable and opened another terminal and ran, tpm2_pcrread command which has to show pcr data,

tpm2_pcrread

it fails because there is no /dev/tpm0 file. But in server log,
