Description
Hi!
I don't really know what I'm doing, but following the stdlib fpm build instructions I get to here:
at which point I get the error message:
gfortran -c ./src/stdlib_hash_64bit.f90 -O3 -funroll-loops -Wimplicit-interface -fPIC -fmax-errors=1 -fcoarray=single -J build/gfortran_EDF3F128DBFCA123 -Ibuild/gfortran_EDF3F128DBFCA123 -o build/gfortran_EDF3F128DBFCA123/stdlib/src_stdlib_hash_64bit.f90.o ./src/stdlib_hash_64bit.f90:66:29:
66 | pow64_over_phi = int(z'9E3779B97F4A7C15', int64) | 1 Error: Arithmetic overflow converting INTEGER(16) to INTEGER(8) at (1). This check can be disabled with the option '-fno-range-check' compilation terminated due to -fmax-errors=1.
It's probably something that someone more up on things than me would be able to fix (see see comment below), but figured might be worth reporting anyway. I tried updating gfortran (not sure if this impacts fpm) from conda-forge but still no joy.
I also get the same error when trying to include stdlib in an fpm project toml file.
Expected Behaviour
I expected the build to work :-)
Version of stdlib
v0.1.0
Platform and Architecture
Ubuntu 20.04.3 (x86_64)
