gcc-4.8.5: "error: use of an operand of type‘ bool ’in‘ operator ++ ’is forbidden in C ++ 17"

[BlackMage2]

I get with gcc-4.8.5 a error: use of an operand of type‘ bool ’in‘ operator ++ ’is forbidden in C ++ 17
what gcc Versions are supported?

the complete report is:

i use fedora 34

The gcc of you host is to new to build the old gcc for the toolchain

• use an old linux with old gcc
• or use precompiled toolchains
• or change a .mk file somewhere in toolchains/ and set the gcc compatibility mode, like 94403ec

Are you using the latest version of freetz? I think it should work. Check the commands above the log part how it is compiled

I made a similar issue when building gcc 5.4.0, I am wondering how to bypass this error...

error: use of an operand of type 'bool' in 'operator++' is forbidden in C++17

[fda77]

Its the same, the compile of your system is to new...

There should be a generic solution for this c++-version problem
