vst plugin in lmms 1.2.2 - missing wine libraries

[DeIM]

Hi, I'm trying to enable vst plugin in lmms (vestige). I've overrided mask for vst use flag. I have app-emulation/wine-vanilla 7.2 installed but in log there is:

Code: Select all

-- Could NOT find Wine (missing: WINE_LIBRARIES)
...
* VST-instrument hoster       : not found, please install (lib)wine-dev (or similar) - 64 bit systems additionally need gcc-multilib and g++-multilib
* VST-effect hoster           : not found, please install (lib)wine-dev (or similar) - 64 bit systems additionally need gcc-multilib and g++-multilib

Also noticed there are no .pc files with wine-vanilla installation. Could this be the reason build of lmms don't found wine?

Tried lmms-1.2.2-linux-x86_64.AppImage from upstream pages and vestige is present here.
I've tried to download some free vst plugins but I had no luck.
Output when loading plugin to vestige's dialog:

Code: Select all

002c:err:winediag:getaddrinfo Failed to resolve your host name IP

Returning to this - it seem on another distros VSTs works:

https://github.com/LMMS/lmms/issues/3915
If it works on another (even 64bit) distros, why not Gentoo?
Is there something I can dig in source? It seem configure phase doesn't find wine installation in Gentoo.
Does anyone tried since 2014?

I did

LMMS uses CMake to configure and build the project and both the 1.2.2 and git versions call FIND_PACKAGE(Wine) in the CMakeLists.txt to check for VST support

FIND_PACKAGE(Wine) pulls cmake/modules/FindWine.cmake, this file differs significantly between the 1.2.2 and git version

1.2.2's FindWine.cmake calls FIND_LIBRARY(WINE_LIBRARY NAMES wine ...), which doesn't make sense for me since there is no such thing as libwine.so, version 1.2.2 was released mid 2020 so I suppose this is deprecated functionality since then.

git LMMS's FindWine.cmake instead searches for winegcc (and wineg++) and then extracts the necessary flags to build for wine from it, however, currently it does not find winegcc on Gentoo since it searches on /opt/wine-staging, /opt/wine-devel, /opt/wine-stable (Debian and Ubuntu folders for wine) and /usr/lib/wine

while Gentoo's winegcc resides on /etc/eselect/wine, for the sake of eselect shenanigans

simply adding /etc/eselect/wine on the list(APPEND WINE_LOCATIONS ...) line on git LMMS's FindWine.cmake just works, which deserves a pull request I have already made:

@slidey good job
Can't wait to try it out.
Since original post I moved to git versions and didn't notice any bad behavior, new features are cool.
