I’ve been trying to compile MongoDB 6.0.15 for Alpine Linux 3.19, and it’s been quite challenging, largely due to the use of musl instead of libc.

Among the errors faced are:

In src/mongo/util/aligned.h:
code

src/mongo/util/aligned.h:135:77: warning: use of 'std::hardware_destructive_interference_size' [-Winterference-size]
  135 | using CacheAligned = Aligned<T, stdx::hardware_destructive_interference_size>;
Even when trying to pass the flags -mtune, -mcpu, or --param hardware_destructive_interference_size=64, the error still persists.

Another error that has been hindering me is when compiling src/mongo/util/dns_query_posix_imp.h, I am informed that ‘res_nclose’, ‘res_ninit’, and ‘res_nstatus’ are not referenced. I have checked the file, and it contains the include for resolv.h, which I also have in my system.

I tried

python3 buildscripts/scons.py DESTDIR=/usr/bin/mongod/ install-mongod CXXFLAGS="--param hardware_destructive_interference_size=64"

but
