“使校验”在VPATH中失败

Question

我正在尝试创建一个基于自动工具的项目，其中包含一个libtool目标和测试。

除了VPATH中的make check (或make distcheck)之外，一切都正常工作。

下面是用于测试的Makefile.am：

AM_CPPFLAGS = -I$(top_srcdir)/include
LDADD = $(top_srcdir)/lib/libboilerplate.la

check_PROGRAMS = test test_fail
test_SOURCES = test.c
test_fail_SOURCES = test_fail.c

TESTS = $(check_PROGRAMS)
XFAIL_TESTS = test_fail

以下是make check的输出

以及VPATH的make check输出：

有人知道为什么会这样吗？

Answer 1

你写道：

LDADD = $(top_srcdir)/lib/libboilerplate.la

但是，这会将输出文件放入源树中--这是错误的。使用$(top_builddir)代替。
