I'm not fully understanding how to use it maybe. However, I tried basing it on the dump example, and my guesses were as follows: for every track, I'm supposed to get an enum midi_parser_status of MIDI_PARSER_TRACK once, followed by multiple times of MIDI_PARSER_TRACK/MIDI_PARSER_TRACK_META/MIDI_PARSER_TRACK_SYSEX until I reach the end of that particular track. Followed by all that again for every new track. So far, so good.

However, with the following midi file the header reports 14 tracks, but I only get 3 times MIDI_PARSER_TRACK before the end of file, and there are basically almost no note on/offs even though this is clearly a very busy song, and most events are just of status type "unknown" (as per midi_status_name). So something seems to be going wrong here. Or should I be doing something to extract note info from these unknown events? But how?

Here is the midi file:
test.mid.zip

~/Desktop/midi-parser-master/src$ gcc midi-parser.c -o midi-parser
Undefined symbols for architecture arm64:
"_main", referenced from:
implicit entry/start for main executable
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

// same with make

Hi. I am not an experienced C developer, just a halfwit able to run the media-autobuild suite to build ffmpeg and related linked projects, and interpreting error messages when anything fails.

Here I tried to use an interactive MinGW shell to build your midi-parser. I learned that the file mman.h does not exist by default in an MSYS2 installation, so I installed the package msys2-runtime-devel. Now I have the file /usr/include/sys/mman.h. Yet it seems not to be included by default in the includes paths, which confuses me.

BTW, running cmake . generates a ninja build script in the MSYS2 environment of MABS, but that should be quite equal to a makefile.

$ ninja

I wonder if I should help cmake finding include paths by adding parameters, but I have no clue which would be appropriate.
