Automake錯誤建築庫 - 幻影文件

Question

我將autotools功能添加到個人圖書館，但我遇到了一些問題。我確定自動工具對我來說是全新的。

. 
|-- Makefile.am 
|-- configure.ac 
`-- socket++ 
    |-- Makefile.am 
    |-- base_socket.cpp 
    |-- base_socket.hpp 
    |-- client.cpp 
    |-- client.hpp 
    |-- config.h 
    |-- config.h.in 
    |-- refcount++.hpp 
    |-- server.cpp 
    |-- server.hpp 
    |-- server.imp.hpp 
    `-- types 
     |-- Makefile.am 
     |-- simple_socket.cpp 
     |-- simple_socket.hpp 
     |-- simple_socket_stop.cpp 
     |-- simple_socket_stop.hpp 
     |-- text_buffered.hpp 
     `-- text_buffered.imp.hpp 

這裏是configure.ac

AC_INIT([socket++], [1.2], [xcodexif@xif.fr], [socket++], [http://dev.xif.fr/socketxx]) 
AM_INIT_AUTOMAKE([foreign -Wall]) 
AC_CONFIG_HEADERS([socket++/config.h]) 
AC_CONFIG_SRCDIR([socket++/base_socket.cpp]) 
AC_CONFIG_FILES([Makefile socket++/Makefile socket++/types/Makefile]) 
AC_CONFIG_MACRO_DIR([m4]) 

# Distribute additional compiler and linker flags 
AC_SUBST([AM_CXXFLAGS]) 
AC_SUBST([AM_LDFLAGS]) 

# Checks for compilers 
AC_PROG_CXX 
AC_PROG_CC 
AX_CXX_COMPILE_STDCXX_11 

# Libtool 
LT_INIT 
LT_LANG([C++]) 

# Checks for header files 
AC_CHECK_HEADERS([arpa/inet.h inttypes.h netdb.h netinet/in.h stddef.h sys/ioctl.h sys/socket.h unistd.h]) 

# Checks for typedefs, structures, and compiler characteristics

AC_OUTPUT 

這裏是socket++/Makefile.am

AUTOMAKE_OPTIONS = subdir-objects 
ACLOCAL_AMFLAGS = ${ACLOCAL_FLAGS} 
AM_CXXFLAGS = -I$(top_srcdir)/socket++ @AM_CXXFLAGS@ 
ACLOCAL_AMFLAGS = -I m4 

SUBDIRS = types 

lib_LTLIBRARIES = libsocket++.la 
library_includedir=$(includedir)/socket++ 
library_include_HEADERS = refcount++.hpp base_socket.hpp client.hpp server.imp.hpp server.hpp 
libsocket++_la_SOURCES = base_socket.cpp client.cpp server.cpp 
socket++_libincludedir = $(libdir)/socket++/include 
nodist_socket++_libinclude_HEADERS = config.h 
libsocket++_la_LIBADD = types/libsocket++types.a 

最後socket++/types/Makefile.am

noinst_lib_LTLIBRARIES = libsocket++types.la 
library_includedir=$(includedir)/socket++/types 
library_include_HEADERS = simple_socket_stop.hpp simple_socket.hpp text_buffered.imp.hpp text_buffered.hpp 
libsocket++types_la_SOURCES = simple_socket_stop.cpp simple_socket.cpp 

全部是罰款./configure 但是，當我make，我有這樣的錯誤：

make[3]: Entering directory '/root/socket++/socket++/types' 
make[3]: *** No rule to make target 'libsocket++types.c', needed by 'libsocket++types.lo'. Stop. 

，由於libsocket++types.c從未在libsocket++types_la_SOURCES

定義我搜索了一段時間，但沒有發現任何有關文件的幻影像這樣奇怪。 在此先感謝您的幫助！

只是有與使用<prefix>_初選的幾個問題：

lib_LTLIBRARIES = libsocket++.la導致libsocket__的derived variable name

libsocket___includedir = $(includedir)/socket++ 
libsocket___include_HEADERS = ... 
libsocket___la_SOURCES = ... 

你可以把頭文件中_SOURCES名單。即，如果標題被改變，make將會看到該庫或其他依賴項必須被重新編譯。

你稱之爲「幻影」目標，通常稱爲convenience library，其中：libsocket++types.la轉換爲libsocket__types_前綴。父母Makefile.am應添加包含路徑到AM_CPPFLAGS。由於subdirs會先下降，您可以添加便利庫：

libsocket___la_LIBADD = types/libsocket++types.la

此外，它noinst_LTLIBRARIES不noinst_lib_LTLIBRARIES。
