# Build the executable binary (CGO_ENABLED=1 is required for go boring).
# Even though we need cgo to call the boring crypto C functions, these
# functions are statically linked into the binary. We also want to statically
# link any libc bits hence we pass "-linkmode=external -extldflags -static"
# to the ldflags directive. We do not pass "-s" to ldflags because we do
# not want to strip symbols - those are used to verify if we compiled correctly.
# We do not pass in GOCACHE (build cache) and GOMODCACHE (module cache)
# because there have been bugs in the Go compiler caching when using cgo
# (it will sometimes use cached artifiacts when it should not). Since we
# use gcc as the C compiler, the following warning is emitted:
# /boring/boringssl/build/../crypto/bio/socket_helper.c:55: warning:
# Using 'getaddrinfo' in statically linked applications requires at
# runtime the shared libraries from the glibc version used for linking
# This is referring to the code in
# https://github.com/google/boringssl/blob/af34f6460f0bf99dc267818f02b2936f60a30de7/crypto/bio/socket_helper.c#L55
# which calls the getaddrinfo function. This function, even when statically linked,
# uses dlopen to dynamically fetch networking config. It is safe for us to ignore
# this warning because the go boring cypto code does not create netowrking connections:
# https://github.com/golang/go/blob/9d6ab825f6fe125f7ce630e103b887e580403802/src/crypto/internal/boring/goboringcrypto.h
# The osusergo and netgo tags are used to make sure that the Go implementations of these
# standard library packages are used instead of the libc based versions.
# We want to have no reliance on any C code other than the boring crypto bits.
# Setting GOOS=linux GOARCH=amd64 is a hard requirment for boring crypto:
# https://github.com/golang/go/blob/9d6ab825f6fe125f7ce630e103b887e580403802/misc/boring/README.md?plain=1#L95
# Thus trying to compile the pinniped CLI with boring crypto is meaningless
# since we would not be able to ship windows and macOS binaries.
