【问题描述】：
我正在尝试从源代码构建 GCC，当我尝试使用 ./configure --prefix=/tmp/gcc 配置 gmp 4.3.2 时，我收到以下错误消息
checking if globals are prefixed by underscore... ./configure: line 30083: nm: command not found
unknown

我已经安装了binutils-2.34-6ubuntu1，我在网上找到了nm命令所在的位置，但是我通过which命令找不到它。如果有解决此问题所需的任何其他信息，请告诉我。
提前感谢您的帮助。
【问题讨论】：
-
你是如何安装 binutils 的？您能否在您的文件系统中找到
nm命令（例如，它是否位于/usr/bin/nm）？PATH变量（即echo $PATH）的内容是什么？ -
除上述之外，尝试：
dpkg -L binutils它将列出该软件包安装的文件的位置。以良好的 IT 方式，也许只是尝试重新启动，因为这些是相当低级的工具...... -
我通过
sudo apt-get install binutils安装了binutils。我的路径看起来像这样/home/"the name of the user"/ARMCompiler6.15/bin /home/"the name of the user"/.local/bin /usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin /usr/games /usr/local/games -
dpkg -L binutils给了我这个输出/usr/bin/nm，而/usr/bin/似乎在我的路径中 -
我浏览了
/usr/bin，但找不到nm。
