One problem with the PKGBUILD is it's referencing the wrong tarball. It should at least be coming from the release page on github, or from sourceforge. I'm not sure which one should be considered the source.

Yes, then autoreconf shouldn't be required in the PKGBUILD. The files at both sources are identical. I'd say go with sourceforge since the website is still there.

In the OPTDEPENDS I'd suggest changing "ogg support" and "mp3 support" to "ogg export" and "mp3 export", so people don't feel let down when they find the support is only for export.

For GCC 10, add -fcommon to CFLAGS to get the build to succeed:

    CFLAGS=-fcommon ./configure --prefix=/usr

OR

https://sourceforge.net/projects/gwc/files/gwc2/0.22-4/gtk-wave-cleaner-0.22-04.tar.gz/download

Then do the standard "./configure; make". However there are multiple problems with the code (mismatched preprocessor 'else', defining globals inside header files without 'extern', not using 'static' on variables inside c files)

After those are fixed, it works.

There is bug in gcc, or code is not compliant with newer standard. It builds for me with clang, you have to add CC=clang where make is invoked.

@mwohah Could you please try new version? machine.h is part of gwc sources.

I get an error pertaining to "machine.h" not being found.

I have no idea what package this header is supposed to belong to, but it should probably be listed as make dependency.
