error: too many template arguments for class template 'Scoped'

[ryandesign]

I can't compile gpick 0.3 at the moment due to its lua-c++ requirement so I'm trying to compile gpick 0.2.6 which fails on macOS with:

In file included from source/dynv/Xml.cpp:23:
source/common/Scoped.h:94:9: error: too many template arguments for class template 'Scoped'
        return Scoped<Callable, Args...>(callable, args...);
               ^                ~~~~~~~~
source/common/Scoped.h:37:8: note: template is declared here
struct Scoped;
       ^

I didn't see any other ticket reporting this error. The only hit on Google for this error was this summary of Debian builds that failed with clang but no solution mentioned there.

Hi, I managed to successfully build version 0.2.6 with clang 14.0.6 after making the following change to source/common/Scoped.h file:

--- source/common/Scoped.h
+++ source/common/Scoped.h
@@ -33,7 +33,7 @@
    return apply(f, t, std::make_index_sequence<size> {});
 }
 }
-template<typename>
+template<typename...>
 struct Scoped;
 template<typename... Args>
 struct Scoped<void (*)(Args...)> {

If compilation with this fix applied still fails for you, then I will need full error and compiler version.

Thanks, that lets me get past that error.
