Error when compiling Z3

[DavidAdamczyk]

Hello,
I have question about readme instructions. The second step is compile Z3 version 4.6.2 (5651d00751a1eb40b94db86f00cb7d3ec9711c4d) but I found this error:

The error is probably solved by Z3Prover/z3#1688

So the question is which is the right commit hash (or tag, or Z3 version?)

[DavidAdamczyk]

I found the second one Z3Prover/z3#1622
Please let me know which version/hash is supported with fastsmt.

I also encountered the same problem when compiling the latest code d2330055e732dacc9423f54a271fdaa235515ad0, but when I checkout to release 4.8.10, it could be compiled successfully.

Environment: Ubuntu 20.04.2 GCC (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0
