Warnings "__VA_ARGS__ is a GNU extension" in clang-3.7 compiler
(This issue was migrated from the old bug tracker of SQLiteStudio)
Original ID from old bug tracker: 3100 Originally created at: Thu Jun 16 21:35:41 2016 Originally last updated at: Thu Jun 16 21:35:41 2016
Seeing a lot of these warnings: ./config_builder.h:14:90: warning: token pasting of '','' and VA_ARGS is a GNU extension [-Wgnu-zero-variadic-macro-arguments]
Operating system: FreeBSD 64-bit
Version: 3.1.0

Yes, SQLiteStudio sourcecode uses variadic macros. For now I don't know a standarized way to implement features I needed, so for now they have to stay.

Clang says that to silence the warning -Wgnu-zero-variadic-macro-arguments needs to be added, I think.

It's a bit more complicated. I think they have answer here http://stackoverflow.com/questions/26932749/how-can-wgnu-zero-variadic-macro-arguments-warning-be-turned-off-with-clang
I will try it out when I have a little time for it.

Status changed to assigned
fwiw, the warning is still shown with clang 13 on OpenBSD:
../../../SQLiteStudio3/coreSQLiteStudio/config_builder.h:14:90: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments]
Yes. The issue is still open, as there are more important things than getting rid of a warning, which actually is not that simple as it may look like.
