我在binutils-2.29 / binutils目录中更改了Makefile.am以创建新库。所以我运行以下命令来创建一个新的Makefile
dinesh@dinesh-HP-Ubuntu:/home/packages/binutils-2.29$ sudo libtoolize && aclocal -I./ && autoreconf && automake
它给了我以下错误：
dinesh@dinesh-HP-Ubuntu:/home/packages/binutils-2.29$ sudo libtoolize && aclocal -I./ && autoreconf && automake
libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
autom4te: cannot open autom4te.cache/requests: Permission denied
aclocal: error: echo failed with exit status: 1
但是在Parent目录中没有Makefile.am，子目录中有Makefile.am。 当我搜索Makefile.am时，我得到了这个：
dinesh@dinesh-HP-Ubuntu:/home/packages/binutils-2.29$ find -iname "Makefile.am" | xargs grep -inr "ACLOCAL_AMFLAGS"
./gas/Makefile.am:21:ACLOCAL_AMFLAGS = -I .. -I ../config -I ../bfd
./gold/Makefile.am:26:ACLOCAL_AMFLAGS = -I ../bfd -I ../config
./opcodes/Makefile.am:21:ACLOCAL_AMFLAGS = -I .. -I ../config -I ../bfd
./binutils/Makefile.am:21:ACLOCAL_AMFLAGS = -I .. -I ../config -I ../bfd
./ld/Makefile.am:21:ACLOCAL_AMFLAGS = -I .. -I ../config -I ../bfd
./zlib/Makefile.am:5:ACLOCAL_AMFLAGS = -I .. -I ../config
./gprof/Makefile.am:21:ACLOCAL_AMFLAGS = -I .. -I ../config -I ../bfd
./bfd/Makefile.am:21:ACLOCAL_AMFLAGS = -I . -I .. -I ../config
我应该在哪个Makefile.am中添加-I m4？
同样在父目录中，有不同扩展名的Makefile
dinesh@dinesh-HP-Ubuntu:/home/packages/binutils-2.29$ ls Makefile.*
Makefile.def Makefile.in Makefile.tpl
