我正确使用 libtool 吗？
我正在运行 Linux，Ubuntu 10.04 。
这不是我第一次尝试使用自动工具。我做了很多研究并遵循了很多教程：这是我想做的、我尝试过的以及我面临的问题。
目标：
- 使用 libtool、autoconf 和 automake 编译（然后交叉编译，但这将是另一项工作）我自己的用 C 编写的库
我尝试过的内容以及我所处的位置 :
库名称为FXPLib，包名称为libfxplib-0.1
我的项目文件夹是：
Makefile.am（唯一的一个） 包括 include/fxplib.h（主头文件） 包括/FXPLib include/FXPLib/header1.h（这些是公共标头） 包含/FXPLib/header2.h 包括/FXPLib/... 源代码 src/sub1/file1.c src/sub2/file1.c src/sub3 ...我运行了自动扫描，得到了一个configure.ac，如下编辑：
<前><代码># -*- Autoconf -*- # 使用 autoconf 处理此文件以生成配置脚本。 AC_PREREQ([2.65]) AC_INIT([libfxplib-0.1], [0.1], [<>]) AC_CONFIG_SRCDIR([src/object_system/FXP_image_s.h]) AC_CONFIG_HEADERS(config.h) AC_CONFIG_MACRO_DIR([m4]) AM_INIT_AUTOMAKE AM_PROG_LIBTOOL LT_PREREQ([2.2]) LT_INIT # 检查程序。 AC_PROG_CC AC_PROG_MAKE_SET # 检查库。 # 检查头文件。 AC_CHECK_HEADERS([stdlib.h]) # 检查类型定义、结构和编译器特性。 AC_HEADER_STDBOOL # 检查库函数。 AC_FUNC_MALLOC AC_FUNC_REALLOC AC_CHECK_FUNCS([memset]) AC_CONFIG_FILES([生成文件]) 交流输出我像这样编写了Makefile.am：
lib_LTLIBRARIES = libfxplib-0.1.la libfxplib_0_1_la_CFLAGS = -I$(srcdir)/include -I$(srcdir)/include/FXPLib `sdl-config --cflags --libs` -lSDL_image libfxplib_0_1_la_SOURCES = src/sub1/file1.c \ src/sub1/file2.c \ src/sub2/file1.h \ ... nobase_include_HEADERS = include/fxplib.h \ 包括/FXPLib/header1.h \ 包括/FXPLib/header2.h \ ... ACLOCAL_AMFLAGS = -I m4- 然后我运行aclocal和autoheader来获取automake所需的文件
- 然后最重要的： autoconf
- 和：automake --add-missing --copy
从那里，一切都好。但后来我尝试编译：
$ ./configure
一切都好...
$ make
然后我得到：
...
src/graphics_engine/FXP_rendering.c:35:25: error: FXP_image_s.h: File not found
...
其中：
- “graphics_engine”相当于 src/sub
- “FXP_rendering.c”到 src/sub/file.c
- “FXP_image_s.h”到 src/sub2/header.h
这意味着： automake 可以编译子目录中的 .c 文件，但不能在这些文件中包含其他子目录中的私有 .h 文件。
我的问题是：如何告诉 automake 编译每个子目录中的每个文件，就好像它们都在同一个地方一样？
我希望我是可以理解的（对于你在我的话中可能发现的一些问题感到抱歉，因为我是法国人）
提前谢谢你。
I am running Linux, Ubuntu 10.04 .
It is not the first time I try to use autotools. I did a lot of researches and follow a lot of tutorials : here is what I want to do, what I tried and what issue I am facing.
Goal :
- compile (and then cross-compile, but this will be an other job) my own library coded in C using libtool, autoconf and automake
What I tried and where I am :
The library name is FXPLib, the package name is libfxplib-0.1
My project folder is :
Makefile.am (the only one) include include/fxplib.h (main header) include/FXPLib include/FXPLib/header1.h (these are public headers) include/FXPLib/header2.h include/FXPLib/... src src/sub1/file1.c src/sub2/file1.c src/sub3 ...I ran autoscan, got a configure.ac, edited it as here :
# -*- Autoconf -*- # Process this file with autoconf to produce a configure script. AC_PREREQ([2.65]) AC_INIT([libfxplib-0.1], [0.1], [<>]) AC_CONFIG_SRCDIR([src/object_system/FXP_image_s.h]) AC_CONFIG_HEADERS(config.h) AC_CONFIG_MACRO_DIR([m4]) AM_INIT_AUTOMAKE AM_PROG_LIBTOOL LT_PREREQ([2.2]) LT_INIT # Checks for programs. AC_PROG_CC AC_PROG_MAKE_SET # Checks for libraries. # Checks for header files. AC_CHECK_HEADERS([stdlib.h]) # Checks for typedefs, structures, and compiler characteristics. AC_HEADER_STDBOOL # Checks for library functions. AC_FUNC_MALLOC AC_FUNC_REALLOC AC_CHECK_FUNCS([memset]) AC_CONFIG_FILES([Makefile]) AC_OUTPUTI wrote Makefile.am like this :
lib_LTLIBRARIES = libfxplib-0.1.la libfxplib_0_1_la_CFLAGS = -I$(srcdir)/include -I$(srcdir)/include/FXPLib `sdl-config --cflags --libs` -lSDL_image libfxplib_0_1_la_SOURCES = src/sub1/file1.c \ src/sub1/file2.c \ src/sub2/file1.h \ ... nobase_include_HEADERS = include/fxplib.h \ include/FXPLib/header1.h \ include/FXPLib/header2.h \ ... ACLOCAL_AMFLAGS = -I m4- Then I ran aclocal and autoheader to get files needed by automake
- Then the most important : autoconf
- And : automake --add-missing --copy
From there, everything is ok. But then I try to compile :
$ ./configure
Everything ok too...
$ make
and then I get :
...
src/graphics_engine/FXP_rendering.c:35:25: error: FXP_image_s.h: File not found
...
where :
- "graphics_engine" is equivalent to src/sub
- "FXP_rendering.c" to src/sub/file.c
- "FXP_image_s.h" to src/sub2/header.h
This means : automake can compile .c files in a sub directory, but can't include in these files a private .h file that is in an other sub directory.
My problem is : How to tell automake to compile every files in every subdirectories as if they were all in the same place ?
I hope I am understandable (and sorry for some problems you could find in my words, cause I am French)
Thank you by advance.

您的
configure.ac和Makefile.am文件看起来您一定投入了大量的精力来学习。恭喜！一个有用的提示是，您可以只运行autoreconf而不是整个aclocal、autoheader、autoconf链，automake等。这种情况下的问题实际上不是 autotools，而是 C 编译器本身 - 您正在项目的根目录中执行编译器来编译
src/sub< 中的文件/code>，但由于 src/sub2 既不是当前目录，也不是包含路径，编译器不知道在哪里找到它。尝试将
-I$(srcdir)/src/sub2添加到Makefile.am中的libfxplib_0_1_la_CFLAGS行。这将更改包含路径，以便指示编译器在 src/sub2 中查找头文件，因此您必须为包含以下内容的每个sub目录添加类似的指令在另一个目录中使用的头文件。Your
configure.acandMakefile.amfiles look like you must have put a lot of effort into learning. Congratulations! One useful tip is that you can just runautoreconfinstead of the whole chain ofaclocal,autoheader,autoconf,automake, etc.The problem in this case is actually not the autotools, but the C compiler itself - you are executing the compiler in your project's root directory to compile a file in
src/sub, but sincesrc/sub2is neither the current directory nor in the include path, the compiler doesn't know where to find it.Try adding
-I$(srcdir)/src/sub2to yourlibfxplib_0_1_la_CFLAGSline inMakefile.am. This will change the include path so as to instruct the compiler to look for header files insrc/sub2, so you will have to add a similar instruction for everysubdirectory containing header files used in another directory.
