为什么automake无法生成Makefile.in

Question

尝试使用automake/autoconf(分别为1.10和2.61版本).一切都运行正常,除了automake没有生成Makefile.in.

产生了一些警告,但我认为它们并不重要.然而,最后一行让我觉得它产生的东西应该不会停在那里.项目中有一个md5.cc和md5.c文件.

Makefile.am: object `md5.$(OBJEXT)' created by `md5.cc' and `md5.c'

configure.ac的相关内容:

AC_INIT(testapp, 1.1, user@blah.com)
AM_INIT_AUTOMAKE(testapp,1.1)
AC_OUTPUT(Makefile)

Makefile.am的内容:

AUTOMAKE_OPTIONS = foreign

CFLAGS=-O2
bin_PROGRAMS = testapp
testapp_SOURCES = interface.cc interface.hh keymgr.cc keymgr.hh main.cc manage.cc manage.hh md5.c md5.cc md5.h mm.cc mm.hh mysqldb.cc mysqldb.h testapp.cc testapp.h

我一直在谷歌搜索该问题,但没有发现任何有用的东西.

命令运行是:

autoscan
mv configure.scan configure.ac
(edit configure.ac)
autoconf
(edit Makefile.am)
aclocal
automake --add-missing

有人之前看过这样的事情,或者知道我怎么可以打开一些额外的调试来解决这个问题？

Answer 1

Makefile.am: object `md5.$(OBJEXT)' created by `md5.cc' and `md5.c'

是一个导致Automake中止的错误消息.这两个文件必须编译成md5.o,所以这是一个问题.

你能重命名这两个文件中的一个吗？
