If you get the error:
amidiminder.cpp:2:28: fatal error: alsa/asoundlib.h: No such file or directory

Then you can fix this by installing libasound2-dev:
sudo apt-get install libasound2-dev

Steps to repro:

1. Create your own /etc/amidiminder.rules file.
2. Make a new version of amidiminder.
3. Use sudo dpkg -i ... to install the new version.

Your /etc/amidiminder.rules file is now the default. :(

Hi there!

I've got amidiminder working on a Libre Le Potato single board computer, running their customize Raspbian, based on Debian 11.6. I had no problems building and installing it, it seems to be working, hooray!

I'm developing the MIDI tool I'm using mostly on my Ubuntu Studio 22.04 laptop, however, a regular amd64 machine running g++ 11.3.0. When I try to build amidiminder there it fails trying to compile the rule.cpp file. It doesn't like the usage of the Parse class, raising errors like this:

rule.cpp: In function ‘ClientSpec {anonymous}::parseClientSpec(const string&)’:
rule.cpp:168:56: error: cannot bind non-const lvalue reference of type ‘std::ostream&’ {aka ‘std::basic_ostream<char>&’} to an rvalue of type ‘std::basic_ostream<char>’
  168 |       throw Parse(Error() << "malformed client '" << s << "'");
      |                   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~
rule.cpp:159:27: note:   initializing argument 1 of ‘{anonymous}::Parse::Parse(std::ostream&)’
  159 |       Parse(std::ostream& o) : std::string(errormsg(o)) { }
      |             ~~~~~~~~~~~~~~^

I don't know c++ at all, so I don't really know where to start with this. I tried removing the & from Parse(std::ostream& o) since the error talks about a mismatch between std::basic_ostream<char>& and std::basic_ostream<char>, but that also fails, with messages like this:

rule.cpp:168:62: error: ‘std::basic_ostream<_CharT, _Traits>::basic_ostream(std::basic_ostream<_CharT, _Traits>&&) [with _CharT = char; _Traits = std::char_traits<char>]’ is protected within this context

Is there an easy fix to get this to build on my laptop?

Thanks!

Awesome project! I have been looking for a good mapping solution for hours and I was about to write my own in python. But this is just what I had in mind. Luckily I found this.

However, the check command does not seem to work (logically)

$ amidiminder -C
no rules file specified, so no rules added

After making changes I need to run

$ systemctl restart amidiminder

It'd be great if this was explicitly mentioned as a requirement to apply changes in the readme / example config. It would be good to mention what the amidiminder does when it's executed without any parameters.

sudo amidiminder -C
no rules file specified, so no rules added

I setted my simple rules at the /etc/amidiminder.rules , but I cant get it to read them

Running on raspberry pi with PatchBox OS. Works like a charm otherwise , thanks for this marvellous tool !
