Building p7zip with GCC 11 or newer normally fails with error messages like
|
||
|
||
../../../../CPP/7zip/Archive/Wim/WimHandler.cpp:308:11: error: use of an
|
||
operand of type ‘bool’ in ‘operator++’ is forbidden in C++17
|
||
308 | numMethods++;
|
||
| ^~~~~~~~~~
|
||
|
||
This patch causes GCC to interpret the code using the GNU dialect of the C++14
|
||
standard, as GCC 10 did by default, and reduces these errors to warnings.
