# Default build: dynamically linked so go-nvml can dlopen libnvidia-ml at
# runtime for GPU metrics. Requires cgo (CGO_ENABLED=1, the default).
build:
go build -o parca-agent -buildvcs=false -ldflags="-extldflags=-static" -tags osusergo,netgo
go build -o parca-agent -buildvcs=false -tags osusergo,netgo

# Fully-static build without NVML GPU metrics. go-nvml cannot dlopen in a static
# binary, so the "nonvml" tag swaps in a no-op producer (gpumetrics/nvidia_stub.go).
build-static:
go build -o parca-agent -buildvcs=false -ldflags="-extldflags=-static" -tags osusergo,netgo,nonvml

build-debug:
go build -o parca-agent-debug -buildvcs=false -ldflags="-extldflags=-static" -tags osusergo,netgo -gcflags "all=-N -l"
go build -o parca-agent-debug -buildvcs=false -tags osusergo,netgo -gcflags "all=-N -l"
