Question

我正在测试一些autotools的东西，我注意到我得到了一个双重链接，这是主要文件：

configure.ac

AC_INIT([galarm], [1.0], [aullidolunar@gmail.com])
AC_CONFIG_SRCDIR([src/main.c])
AC_CONFIG_AUX_DIR([build-aux])
AM_INIT_AUTOMAKE([-Wall -Werror foreign subdir-objects])
AM_SILENT_RULES([yes])
AC_CONFIG_HEADERS([config.h])
LT_INIT([disable-static])
AC_PROG_LIBTOOL
IT_PROG_INTLTOOL([0.40.0])
AC_CONFIG_MACRO_DIR([m4])

# Checking debug or release enable
AC_ARG_ENABLE(debug, AS_HELP_STRING([--enable-debug], [Build with debug information [default=no]]), [], [enable_debug=no])
AM_CONDITIONAL([ENABLE_DEBUG], [test "x$enable_debug" != "xno"])

# Checking for local mode
AC_ARG_ENABLE(local, AS_HELP_STRING([--enable-local], [Build with local data resource [default=no]]), [], [enable_local=no])
AM_CONDITIONAL([ENABLE_LOCAL], [test "x$enable_local" != "xno"])

# Checking gtk+-2.0: requiered
PKG_CHECK_MODULES([gtk2], [gtk+-2.0])

GETTEXT_PACKAGE=$PACKAGE
AC_SUBST(GETTEXT_PACKAGE)
AC_DEFINE_UNQUOTED(GETTEXT_PACKAGE,"$GETTEXT_PACKAGE", [package name for gettext])

AC_CONFIG_FILES([
    po/Makefile.in
    src/Makefile
    Makefile
])

AC_OUTPUT

的src / Makefile.am

ACLOCAL_AMFLAGS = -I m4 ${ACLOCAL_FLAGS}

if ENABLE_LOCAL
my_data_dir = "$(abs_top_builddir)/data"
my_locale_dir = "$(abs_top_builddir)/po"
else
my_data_dir = "$(datadir)/$(PACKAGE)"
my_locale_dir = "$(my_data_dir)/locales"
endif

if ENABLE_DEBUG
my_build_type = -g3 -O0
else
my_build_type = -O2
endif

bin_PROGRAMS = galarm
galarm_SOURCES = main.c
noinst_HEADERS = 

DEFS = -DDATA_DIR=\"$(my_data_dir)\" -DLOCALEDIR=\"$(my_locale_dir)\"
galarm_CFLAGS = $(my_build_type) $(gtk2_CFLAGS)
galarm_LDADD = $(gtk2_LIBS) $(LTLIBINTL)
galarm_LDFLAGS = -rdynamic

这是详细的输出：

如您所见，有一个双重链接调用。这是正常的吗？任何方式只使用一次？感谢。

我认为你的帖子的换行符被破坏了，所以很难说出你想要点什么的人。

但总的来说，您所看到的是../libtool与--mode=link的通话，然后是脚本本身报告libtool: link:（因为这就是它的问题。）

只有一个gcc来电有效执行。

为什么我会获得双倍链接？
