I'm trying to build GCC from source, and when I tried to configure gmp 4.3.2 using ./configure --prefix=/tmp/gcc, I get the following error message

checking if globals are prefixed by underscore... ./configure: line 30083: nm: command not found

I have already install binutils-2.34-6ubuntu1, which I found online to be where the command nm is located, but I cannot find it through the which command. If there is any other information necessary to solve this issue, please let me know.

Thank you for your help in advance.

  • How did you install binutils? Can you find the `nm` command in your file system (for example, is it located at `/usr/bin/nm`)? What is the content of the `PATH` variable (i.e. `echo $PATH`)? – f9c69e9781fa194211448473495534 Nov 11 '20 at 20:43
  • in addition to the above, try: `dpkg -L binutils` Which will list the locations of files installed by that package. In good IT fashion, perhaps just try rebooting as these are pretty low level tools... – LT 'syreal' Jones Nov 11 '20 at 20:46
  • I installed binutils through `sudo apt-get install binutils`. My path looks like this `/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` – Arkan Abuyazid Nov 12 '20 at 18:41
  • `dpkg -L binutils` gives me this output `/usr/bin/nm`, and `/usr/bin/` seems to be in my PATH – Arkan Abuyazid Nov 12 '20 at 18:43
  • I looked through `/usr/bin` and I could not find `nm`. – Arkan Abuyazid Nov 12 '20 at 18:48

Doing sudo apt-get install --reinstall binutils solved the problem.
