automake 用于创建库和使用它的程序
我正在尝试开发一个程序，该程序使用在同一项目中完成的另一个内部库。
我想将两者链接起来。该库已在 ./lib/mylib 下存储并成功编译，并创建了 mylib.a。问题是我需要在 INCLUDE 搜索中包含 ./lib/mylib 目录，并将程序链接到库。
是否有任何自动定义的变量，或者我必须像下面的 Makefile.am 中那样自己定义变量？
SUBDIRS = lib .
# set the include path found by configure
INCLUDES = $(all_includes) -Ilib/mylib
bin_PROGRAMS = myprogram
myprogram_SOURCES = main.c
myprogram_CPPFLAGS = $(libmylib_CFLAGS) $(AM_CFLAGS) $(CFLAGS)
nfc_network_config_LDADD =$(LIB_MYLIB)
I'm trying to develop a program that uses another internal library done in the same project.
I want to link both. The lib is stored and succesfully compiled under ./lib/mylib and a mylib.a is created. The issue is that I need to include ./lib/mylib directory in the INCLUDE search and also link the program against the library.
Are there any automatically defined variables or do I have to do it by my own like in the Makefile.am below?
SUBDIRS = lib .
# set the include path found by configure
INCLUDES = $(all_includes) -Ilib/mylib
bin_PROGRAMS = myprogram
myprogram_SOURCES = main.c
myprogram_CPPFLAGS = $(libmylib_CFLAGS) $(AM_CFLAGS) $(CFLAGS)
nfc_network_config_LDADD =$(LIB_MYLIB)

您的
Makefile可能如下所示。请注意，
*_CPPFLAGS通常不应与*_CFLAGS混合使用，并且$(CFLAGS)和$(CPPFLAGS)< /code> 变量总是被使用（它们是用户变量），所以你不必提及它们。另外INCLUDES是一个过时的变量（您应该使用*_CPPFLAGS代替），如果您使用-Wall运行它，automake 会发出警告。选项。Your
Makefilecould look something like this.Note that
*_CPPFLAGSshould usually not be mixed with*_CFLAGS, and that the$(CFLAGS)and$(CPPFLAGS)variables are always used (they are user variables) so you should not have to mention them. AlsoINCLUDESis an obsolete variable (you should use*_CPPFLAGSinstead), and automake will warn about it if you run it with the-Walloption.
