Two problems in the Quickstart Guide

[yttriumzz]

1. mbedtls builds static libraries by default, which will cause an opentee build error.

   build fail:

   /usr/bin/ld: //usr/local/lib/libmbedcrypto.a(bignum.o): relocation R_X86_64_PC32 against symbol `mbedtls_mpi_free' can not be 
   used when making a shared object; recompile with -fPIC
   /usr/bin/ld: final link failed: Bad value
   collect2: error: ld returned 1 exit status
   Makefile:815: recipe for target 'libInternalApi.la' failed
   make[1]: *** [libInternalApi.la] Error 1
   make[1]: Leaving directory '/home/code/VirtualTEE/build/emulator'
   Makefile:327: recipe for target 'all-recursive' failed
   make: *** [all-recursive] Error 1

   solution:

   wget https://github.com/ARMmbed/mbedtls/archive/refs/tags/v3.1.0.tar.gz
   tar -xf v3.1.0.tar.gz && cd mbedtls-3.1.0
   cmake -DUSE_SHARED_MBEDTLS_LIBRARY=On . # <-- this command causes mbedtls to build a dynamic library.
   make -j4 && make install

2. opentee/TAs/example_conversion/sign_ecdsa_256.c encoding error

   build fail:

   ../../opentee/TAs/example_conversion/sign_ecdsa_256.c: In function ‘TA_InvokeCommandEntryPoint’:
   ../../opentee/TAs/example_conversion/sign_ecdsa_256.c:137:2: error: case label does not reduce to an integer constant
     case SIGN_ECDSA_256_SIGN:
     ^~~~
   Makefile:949: recipe for target 'example_conversion/libsign_ecdsa_256_la-sign_ecdsa_256.lo' failed
   make[1]: *** [example_conversion/libsign_ecdsa_256_la-sign_ecdsa_256.lo] Error 1

   solution:

   opentee/TAs/example_conversion/sign_ecdsa_256_ctrl.h, line26

   - const uint32_t SIGN_ECDSA_256_SIGN = 1234;
   + #define SIGN_ECDSA_256_SIGN 1234

Finally, thanks for the recent update ! 😘

Thank you and it is a good catch! I will update a quickstart guide as soon as possible and fixing compile error.

Still processing recent update and therefore documentation might not yet be fully up to date.
