How to fix octave Library not loaded and Abort trap: 6 bug?

Question

Whenever I try to run octave:

$ octave

I get this error:

dyld: Library not loaded: /usr/local/opt/hwloc/lib/libhwloc.15.dylib
  Referenced from: /usr/local/opt/open-mpi/lib/libmpi_usempif08.40.dylib
  Reason: image not found
Abort trap: 6

How do I fix this?

Details:

• Operating system: macOS.

• Octave installed via homebrew command - brew install octave

• Note- I tried to run brew reinstall --build-from-source octave,

But it freezes midway at:

---

==> ./configure --prefix=/usr/local/Cellar/octave/5.1.0_4 --disable-silent-rules

==> make all

---

Answer 1

Make sure hwloc is installed by typing brew install hwloc in your terminal.

---

If that doesn't work, try navigating to the directory its looking for the file in your terminal:

cd /usr/local/opt/hwloc/lib/
ls

Look for a similar library and make a copy of it, renaming it to libhwloc.15.dylib . If there is a file called libhwloc.5.dylib type

cp libhwloc.5.dylib libhwloc.15.dyli
