error: missing binary operator before token "("

[Schildkroet]

Hello,

When trying to compile tinyUSB with MRS2 v230 (GCC12) for CH32V307, i get following error:

In file included from /home/user/MounRiverStudio/230/CH32V307VCT/User/TUSB/tusb_option.h:29:
/home/user/MounRiverStudio/230/CH32V307VCT/User/TUSB/common/tusb_compiler.h:102:90: error: missing binary operator before token "("

tinyusb/src/common/tusb_compiler.h

Line 102 in 6e891c6

#define TU_ARGS_APPLY(_X, _s, ...) TU_XSTRCAT(TU_ARGS_APPLY_, TU_ARGS_NUM(__VA_ARGS__))(_X, _s, __VA_ARGS__)

The compiler doesnt seem to be able to handle this special kind of macro. Do i need some extra flags etc to make it work?

it should work with gcc, maybe something missing on your setup. Try to compile with stock example using provided make/cmake to see if that works for you.
