Error: Cannot load library /usr/lib/tiled/plugins/libyy.so

Hi, somehow when I list --export-formats I got an error message:

$ tiled --export-formats
Error: Cannot load library /usr/lib/tiled/plugins/libyy.so: (/usr/lib/tiled/plugins/libyy.so: undefined symbol: _ZN2Yy10JsonWriter19writeUnquotedMemberEPKcRK10QByteArray)
Map export formats:

Tiled still working fine but I'm curious what is libyy.so?

Hmm, libyy.so is the new GameMaker Studio 2 export plugin. The undefined symbol problem is a little unexpected, especially considering it doesn't happen in the distributed AppImage. When we demangle this symbol, we get:

Yy::JsonWriter::writeUnquotedMember(char const*, QByteArray const&)

Which is defined here:

tiled/src/plugins/yy/jsonwriter.cpp

Lines 178 to 185 in d81fe47

	void JsonWriter::writeUnquotedMember(const char *key,
	const QByteArray &value)
	{
	writeKey(key);
	write(value);
	m_newLine = false;
	m_valueWritten = true;
	}

But, then I realized that Arch Linux builds are based on qmake and I checked the qmake project of the plugin:

tiled/src/plugins/yy/yy.pro

Line 5 in d81fe47

SOURCES += yyplugin.cpp

And it doesn't list jsonwriter.cpp. This being a library that unfortunately doesn't lead to a compile-time error, so we're running into it at runtime instead. :-(

Fortunately the fix is easy. Thanks for the report! :-)

I guess a bug report would have been more appropriate for this, but unfortunately it doesn't appear GitHub provides a way to convert a discussion to an issue. I've pushed a fix in e4ba212, so I've marked this discussion as answered. :-)
