According to https://zcash.readthedocs.io/en/latest/rtd_pages/zcashd.html, I tried to update zcashd to the v4.0.0 on two servers running with CentOS Linux 7.6.XXXX.
For both I got something like the following:
At global scope:
cc1plus: warning: unrecognized command line option “-Wno-builtin-declaration-mismatch” [enabled by default]
make: *** [libbitcoin_server_a-sendalert.o] Error 1
make: Leaving directory
/home/zcash/src' make: *** [all-recursive] Error 1 make: Leaving directory /home/zcash/src’
make: *** [all-recursive] Error 1
Tried a “make clean” before building the update, with no success.
Any idea ?
