自动工具包含路径 [英] Autotools include path

问题描述

我有一个类似

Makefile.am
Configure.ac
         src/
             hello.c
             Makefile.am

         include/
             hello.h

如何在src的Makefile.am中指定包含路径，以使其包含来自include/dir的头文件以及c文件取决于头文件. 因此，如果我修改任何.h文件，它将强制重新编译.cc文件.

How to specify the include path in Makefile.am of src so that it includes header files from include/ dir as well as c file depends on header file. So if I modify any .h file it force to recompile .cc file.

定义AM_CPPFLAGS'会发出警告

Defining AM_CPPFLAGS' is giving warning

configure.ac:5: warning: macro `AM_CPPFLAGS' not found in library

推荐答案

在 src/Makefile.am 中，输入:

AM_CPPFLAGS = -I$(top_srcdir)/include
bin_PROGRAMS = hello
hello_SOURCES = hello.c

无需标记 hello.c 和 hello.h 之间的依赖关系，

There is no need to mark the dependency between hello.c and hello.h, it will be recorded automatically the first time you build your project.
