This file should be updated too, since it is linked from the download page.

I've mirrored the file on the DRD ZDoom SVN build dowload page. Thank you.

Fantastic! :o Yes, the memory leak is fixed. I removed the link to the alternate dll from my post as it's no longer needed.

That seems to fix it. Several map swaps and memory usage barely changed.

Here, I made a new build. This time with fluidsynth 1.1.6 instead of 1.1.1. Watching memory usage in task manager, it seems fine. Would anyone care to confirm?

My "secrets" are that I had to muck about in config file and Makefiles and track down dependencies. It was a pain in the butt. Not so much building Fluidsynth as building glib.

Also, using a libintl replacement that uses the built-in Windows functions instead GNU's libintl saved a lot of space.

I guess that's an efficient compiler (MSVC) versus an inefficient one (gcc).
I have seen it quite often that GCC produces significantly larger binaries, especially when using C++ exceptions. The exception code in there is a lot more complex because it completely sidesteps Windows's exception mechanisms and rolls out its own implementation that also needs to include everything that's normally done by the system itself.

Randy managed to get them to link statically I suppose. If he wants to share his secrets on the topic, I know several people who would be interested.

Probably because it's simply compiled differently? :wink:

Do you know why it needs libglib-2.0-0.dll and libgthread-2.0-0.dll as well when Randy's one only needs fluidsynth.dll (which is also smaller than the one from the jOrgan program)?

I did some further testing and found that the memory leak seems to be present in Randy's compiled fluidsynth.dll, not the ZDoom code.

There is a compiled fluidsynth dll out on the net that works flawlessly with ZDoom, does not have the memory leak and is based on the latest FluidSynth version 1.1.6. I found it in a program called jOrgan.

Have you tried using BASSMIDI driver?

This is really nasty. Any chance of seeing this fixed in the near future? I too ran into this bug though I did not relate it to the Fluidsynth code but rather to the sound font used, and that will probably happen to others, too.

I've encountered the same issue. Music stops playing and will only resume if the [wiki]MIDI device[/wiki] is changed to a non-Fluidsynth one or if quitting and restarting ZDoom.

When using Fluidsynth, soundfonts seem to get loaded each time the music changes, but the old one is still held in memory. This fills the available memory within as much as 4 song changes with a 200MB soundfont.
Also, the error when Fluidsynth fails to load a soundfont when there isn't enough memory available is a somewhat misleading "Failed to load any MIDI patches" message.
