我有以下Makefile来构建我的erlang项目:

.SUFFIXES: .erl .beam .yrl

ERL_SRC := $(wildcard src/*.erl)
ERL_OBJ := $(patsubst src/%.erl,ebin/%.beam,${ERL_SRC})

all: main

main: ${ERL_OBJ}

ebin/%.beam: src/%.erl
        erlc +debug_info -W -o ebin $<

clean:
        rm -fr ebin/*.beam

我正在尝试更新这个以在test/eunit文件夹中构建我的eunit测试,并让输出转到与src相同的ebin文件夹,如下所示:

.SUFFIXES: .erl .beam .yrl

ERL_SRC := $(wildcard src/*.erl)
ERL_OBJ := $(patsubst src/%.erl,ebin/%.beam,${ERL_SRC})
EUNIT_SRC := $(wildcard test/eunit/*.erl)
EUNIT_OBJ := $(patsubst test/eunit/%.erl,ebin/%.beam,${EUNIT_SRC})

all: main

main: ${ERL_OBJ}

ebin/%.beam: src/%.erl test/eunit/%.erl
        erlc +debug_info -W -o ebin $<

clean:
        rm -fr ebin/*.beam

eunit: ${EUNIT_OBJ}

test: main eunit

使主要工作正常,但如果我尝试进行测试它失败了:

make: *** No rule to make target …
