Control: tags -1 + patch Hi,
Michael Crusoe a écrit le 04/10/2019 à 16:01 : > Attached is a patch to force gcc 8; so far it has gotten farther than > the previous failure for me (but my local build is still at 86%) Looking at the related lines of /usr/include/c++/9/bits/stl_function.h, it seems that __builtin_is_constant_evaluated is used only for C++ standard greater or equal to c++14: > #if __cplusplus >= 201402L > #ifdef _GLIBCXX_HAVE_BUILTIN_IS_CONSTANT_EVALUATED > if (__builtin_is_constant_evaluated()) > #else > if (__builtin_constant_p(__x > __y)) > #endif > return __x > __y; > #endif > return (__UINTPTR_TYPE__)__x > (__UINTPTR_TYPE__)__y; Then I tried using '-std=c++11' and the build was successful. Patch attached. Thanks, _g.
