Hi @coderofsalvation, it seems that something might be wrong with the pizmidi plugin. You might try moving it out of the way just to see that the other ones are correctly detected. Also maybe try re-running mw with the --error-report option and attach the corresponding report. I don't have a Linux machine at the moment but I will try to investigate it next time I'm on my Windows box with a Linux VM.

coderofsalvation commented 8 years ago

Hm I think it's not the pizmidi plugin, as it happens even without any plugins installed. mrswatsontest seems to run fine.

MrsWatson is now running in error report mode, which will generate a report on
your desktop with any input/output sources and error logs. This also enables
some extra arguments and will disable console logging.

SUSPECT #2: missing library

$ ldd mrswatson64 
        linux-vdso.so.1 (0x00007ffd4b1a1000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f360aa4d000)

everything seems present. (linux-vdso is a virtual linker-thingie which is never present on a filesystem)

bikubi commented 7 years ago

Same here, on Arch, installed from AUR

Linux xzzo 4.12.13-1-ARCH #1 SMP PREEMPT Fri Sep 15 06:36:43 UTC 2017 x86_64 GNU/Linux

MrsWatson version 0.9.8, build 20150122

UPDATE: whoops, got it to work by specifying an absolute plugin path, like so:

mrswatson64 -m test.mid -p /usr/lib/vst/amsynth_vst.so -o test.wav

...so might be unrelated, or this is about the file scan process (--list-plugins doesn't work).

williamsharkey commented 5 years ago

Source/base/platform.c may read /etc/lsb-release for system info for Linux. I am not sure if Peach Linux has this file, or if it only has /etc/os-release

jussisaurio commented 5 years ago

@williamsharkey this is indeed causing a crash

williamsharkey commented 5 years ago

If someone has a Linux system they want to debug, it might be a good exercise to see if you can clone and build this project. If there are issues getting it to compile, remove everything except the base/platform test. Let me know if you get this working as there are some parts of platform.c I have questions about and would like to break down.

For what it’s worth, the Linux version works on Ubuntu 16 (and probably all newer ones as well)

noobiek commented 4 years ago

Hi all. Ubuntu 18.04 works well.

nikreiman commented 4 years ago

I'm closing this issue, since it seems to be plugin-related (and also quite old). As noted, newer Ubuntu versions (among others) work fine.
