我有一个来自示例项目的makefile，它试图将父目录引用为“../bin”。运行“make install”时，这似乎不起作用。我得到的错误是：
cp: cannot stat `/bin/build/*': No such file or directory
项目布局如下：
/bin
/src/makefile
（所以当我运行makefile时，当前目录是/src/）
似乎用“..”引用父目录是不正确的。我知道我可以使用 {$CURDIR} 变量引用当前目录，但我需要知道正确的变量或引用父目录的方法，以便正确引用 /bin/。我想我可以通过移动makefile来解决这个问题，但我想知道这样做的真正方法以备将来使用。
makefile 看起来像这样（问题用##### 问题###### 突出显示）

我在 Linux Mint 12 上使用 GNU Make 3.81。
谢谢。
的输出
@echo "Installing in profile folder: $(profile_location)"
@echo ${build_dir}
@echo ${profile_location}
是 ：
Installing in profile folder: ~/.mozilla/firefox/8mtbjosv.development/extensions/
../bin/build
