我有一个使用 qemu 创建的 NetBSD VM，我正在尝试使用我使用NetBSD 源代码附带Hello World.c的脚本构建的交叉编译工具链来编译一个简单的程序。build.sh但是，我无法编译程序。

我使用以下命令构建了工具链，

./build.sh -m evbarm tools

./build.sh -m evbarm -U distribution

上述命令的输出产生，

但是，当我尝试helloARM.c使用nbmake-evbarm包装器进行编译时，我得到以下输出，

$ nbmake-evbarm ./helloARM

Stop.

不要将./路径前缀放在目标名称上。

即运行：

nbmake-evbarm helloARM

我当然假设你Makefile在同一个目录中有一个看起来有点像这样的，至少：

PROG = helloARM

.include <bsd.prog.mk>

您必须有这样一个Makefile使用标准 NetBSD 宏的本地程序，因为当没有 makefile 时（或者当 makefile 没有使用正确的 NetBSD 宏时，即<bsd.prog.mk>）使用默认sys.mk宏并且它们不包括${DESTDIR}访问所需的所有魔法目标系统的头文件和库等。
