Bug ID: 104605
Summary: _GLIBCXX_USE_C99_STDINT_TR1 macro is not defined for
canadian cross freestanding C++ toolchain
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: unlvsur at live dot com
Target Milestone: ---
#include<cstdint>
int main()
{
std::uintptr_t p{};
}
This code works on x86_64-elf cross toolchain on linux, but fails to work after
i perform Canadian cross-compilation from linux to windows since
_GLIBCXX_USE_C99_STDINT_TR1 is not defined.
Also stdint.h in GCC is not correctly defined without -ffreestanding flag.
I believe it can be trivialized as just do this
#if __has_include_next(<stdint.h>)
# include_next <stdint.h>
#else
# include "stdint-gcc.h"
#endif
