Build Failure in Intel_Gaudi3_Software Due to Incompatible hl-thunk References

[ywtien]

Issue Description

I am encountering a build issue with the Intel_Gaudi3_Software repository. The build fails during the build_scal step due to missing or incompatible references in the hl-thunk library.

The initial error during the build process is as follows:

make[2]: *** No rule to make target '/home/ywtien/Intel_Gaudi3_Software/builds/latest/libhl-thunk.so', needed by 'lib/libscal.so'.  Stop.

To address this, I attempted to build libhl-thunk.so using the hl-thunk-open project. However, the resulting library appears to be incompatible with the Intel_Gaudi3_Software repository. During the linking phase, the following errors occurred:

/usr/bin/ld: CMakeFiles/scal_tests.dir/scal_gaudi3_test_nic_basic.cpp.o: in function `SCALGaudi3NicTest::initNics()':
/home/ywtien/Intel_Gaudi3_Software/scal/tests/scal_gaudi3_test_nic_basic.cpp:80: undefined reference to `hlthunk_nic_get_ports_masks'
/usr/bin/ld: ../lib/libscal.so: undefined reference to `hlthunk_nic_user_db_fifo_set'
/usr/bin/ld: ../lib/libscal.so: undefined reference to `hlthunk_nic_alloc_user_db_fifo'
collect2: error: ld returned 1 exit status

It seems that the symbols required by Intel_Gaudi3_Software are not present or differ in the hl-thunk-open library. Could you provide guidance on how to resolve this issue or specify the correct steps to obtain a compatible hl-thunk library for this repository?
