Installing MeCab

If you're not on Windows you'll need to install MeCab yourself.

macOS

MeCab is available through Homebrew and MacPorts.

Troubleshooting

Executable not found

If trying to use the add-on's syntax generator results in Mecab error: executable not found you'll need to manually set the path to your MeCab executable:

  1. Determine the location of the executable by running which mecab in the terminal.
    If that command doesn't return a path try looking for a file named mecab in /opt/homebrew/bin/ (Homebrew) or /opt/local/bin/ (MacPorts).
  2. Enter the full path including the final mecab into MeCab executable path in the add-on's preferences (Tools → JRP Add-on Preferences...) and uncheck Use system-wide MeCab executable.

Missing mecabrc

If you get an error like Mecab error: invalid line: param.cpp(69) [ifs] no such file or directory: /path/to/mecabrc, run touch /path/to/mecabrc to create the file in question, where the path is whatever was reported in the error message.

Please report any macOS-related issues that aren't mentioned here. Since I don't own any macOS devices I can't test the add-on on macOS myself.

Linux

Your distro might have a MeCab package, for example:

If you can't find anything, compile MeCab yourself by following the instructions below.

Requirements

  • A C++ compiler. Ideally g++ which, if it isn't installed already, should be available in a package called gcc, g++, or similar on most distros. Check if it works by running g++ --version.
  • libiconv. Probably already present as part of glibc.
  • git, for cloning the repo. You can also skip step 1 below by using the source tarball linked here instead: https://taku910.github.io/mecab/#download

Compile & Install

  1. Clone the repository: git clone https://github.com/taku910/mecab.git
  2. cd into the mecab directory in the repo. It should contain a file called configure.
  3. Run this command:
    ./configure --prefix=/usr --sysconfdir=/etc --libexecdir=/usr/lib --with-charset=utf-8
    For some distros the prefix and directories might be different.
  4. If configure finished without errors, run make (and ensure it succeeds).
  5. Create a temporary target directory.
  6. Run make DESTDIR="<tgt dir>" install, where <tgt dir> is the absolute path of the directory you just made.
  7. Copy or move <tgt dir>/usr/bin/mecab and <tgt dir>/usr/lib/libmecab.so.2 to a new directory. Create an empty file named mecabrc in the same directory.
  8. In the add-on's preferences menu, uncheck Use system-wide MeCab executable and set MeCab executable path to where you put the mecab executable in the previous step.

Alternative to step 5-8 you could also create and install a custom package, in which case you can leave the add-on settings on their default values.
