Make Trait does not work for types with static members with non-standard types #67

Closed gladijos closed 1 year ago

gladijos commented 4 years ago

When I make trait for type with static memder of standard type (int, double, etc.) it works fine. When I make trait for type1 with static memder of non-standard type2 (my own class), even I previously make traits for type2, making trait fore type1 does not work.

A minimal compilable example of that features the bug.

main.cpp

include

include <ThorSerialize/JsonThor.h>

include <ThorSerialize/SerUtil.h>

struct Type1 { int a; }; struct Type2 { static int b; static Type1 c; };

ThorsAnvil_MakeTrait(Type1, a); ThorsAnvil_MakeTrait(Type2, b, c);

using ThorsAnvil::Serialize::jsonExport; using ThorsAnvil::Serialize::jsonImport; int main(int argc, char* argv[]) { std::fstream fileStream; Type2 entity; fileStream >> jsonImport(entity); fileStream << jsonExport(entity); return 0; }

A description of how to build and run the code

g++ -std=c++14 -I/usr/local/include -L/usr/local/lib -lThorSerialize17 main.cpp
cat stuff | ./a.out

Expected behavior

compile OK
