Question

我想为服务器列表执行多个目标。从makefile输出看来，只有$（SERVERS）目标执行了两次。我希望Launch-％执行两次。我怎样才能让它发挥作用。如何访问目标Launch-％中的每个IP地址？请帮帮我。我有以下make文件源代码和输出。提前谢谢。

Makefile source code:
SERVERS=172.16.0.17 172.16.0.100
test-all: test-port-connectivity
test-port-connectivity: Launch-$(SERVERS)
        echo "Test suit 1: Port Connectivity $<"

Launch-%: $(SERVERS)
        echo "Launch Server $<"

$(SERVERS):
        echo "Server IP - $@"

Output of Makefile:
# make 
echo "Server IP - 172.16.0.17"
Server IP - 172.16.0.17
echo "Server IP - 172.16.0.100"
Server IP - 172.16.0.100
echo "Launch Server 172.16.0.17"
Launch Server 172.16.0.17
echo "Test suit 1: Port Connectivity Launch-172.16.0.17"
Test suit 1: Port Connectivity Launch-172.16.0.17

Answer 1

SERVERS=172.16.0.17 172.16.0.100
LAUNCHES=$(addprefix Launch-, $(SERVERS)) # this will be Launch-172.16.0.17 Launch-172.16.0.100

test-all: test-port-connectivity
test-port-connectivity: $(LAUNCHES)
    echo "Test suit 1: Port Connectivity $^"

$(LAUNCHES): Launch-%: %
    echo "Launch Server $<"

$(SERVERS):
    echo "Server IP - $@"

请注意，$(LAUNCHES)规则是static pattern rule。（更简单的pattern rule也足够了，但不够整洁。）另请注意在test-port-connectivity规则中使用$^。

在make文件中涉及目标名称的模式
