大型工程makefile
这几天学习makefile, 读了几遍GNU 文档，感觉不过瘾，求一些大型工程的makefile。

要求：
1、不要小白式的，尽量复杂些。因为个人已经分析了几个大型工程的makefile，以及eclipse CDT 自动生成的makefile。
2、条理清晰一些，比如这种类型的makefile是我喜欢的make_rules/make_conf/Makefile。
3、只要是想探索下思路，然后形成一个比较完备的个人写makefile风格。

真想把分全散掉~~~

[解决办法]
那么真正建议楼主读读autobook（http://www.sourceware.org/autobook/autobook/autobook_toc.html），意味着改转弯了。
[解决办法]
随便找个 C 语言的开源库，都有相当完善的 Makefile.

# Things you might add to DEFS:

# -DPOSIX If you have POSIX.1 headers and

# -DBSD42 If you have sys/dir.h (unless
# you use -DPOSIX), sys/file.h,
# and st_blocks in `struct stat'.
# -DUSG If you have System V/ANSI C
# string and memory functions
# and headers, sys/sysmacros.h,

# -DDIRENT If USG and you have dirent.h
# instead of ndir.h.
# -DSIGTYPE=int If your signal handlers
# return int, not void.

# -DNO_MTIO If you lack sys/mtio.h
# (magtape ioctls).
# -DNO_REMOTE If you do not have a remote shell
# or rexec.
# -DUSE_REXEC To use rexec for remote tape
# operations instead of
# forking rsh or remsh.
# -DVPRINTF_MISSING If you lack vprintf function
# (but have _doprnt).
# -DDOPRNT_MISSING If you lack _doprnt function.
# Also need to define
# -DVPRINTF_MISSING.
# -DFTIME_MISSING If you lack ftime system call.
# -DSTRSTR_MISSING If you lack strstr function.
# -DVALLOC_MISSING If you lack valloc function.
# -DMKDIR_MISSING If you lack mkdir and
# rmdir system calls.
# -DRENAME_MISSING If you lack rename system call.
# -DFTRUNCATE_MISSING If you lack ftruncate
# system call.
# -DV7 On Version 7 Unix (not
# tested in a long time).
# -DEMUL_OPEN3 If you lack a 3-argument version
# of open, and want to emulate it

# with system calls you do have.
# -DNO_OPEN3 If you lack the 3-argument open
# and want to disable the tar -k
# option instead of emulating open.
# -DXENIX If you have sys/inode.h
# and need it 94 to be included.

大型项目一般会用automake或者cmake,来代替直接手写makefile。不过也有手写通用makefile的
[解决办法]
GTK用arm-linux-gcc编了半个月也没编过
楼主有空帮我研究一下！

mark！
[解决办法]
期待，mark下。

奶奶地，好久没看了，，搞不定了，，，，好多函数我认得她 ，不了解她
[解决办法]
手工写makefile太累了，还是用cmake这些工具来完成好些。

我也贴个makfile，在顶层编译整个项目文件，不是很难，不过还是可以研究下：
