Dear list,
I was playing around with g++ when I got this weird behavior:
% cat a.cpp
#include <iostream>
#include <limits>
int main() {
}
% g++ a.cpp
% g++ -m32 a.cpp
In file included from a.cpp:2:0:
/usr/include/c++/4.8.2/limits:1405:35: error: template argument 1 is invalid
struct numeric_limits<__int128>
^
/usr/include/c++/4.8.2/limits:1479:44: error: template argument 1 is invalid
struct numeric_limits<unsigned __int128>
^
%
Compiling with -m32 breaks programs which include <limits>.
Is that a bug? Is there a work-around? Thanks.
Compile with the -v flag and compare the include search paths for -m64 and
for -m32. g++ is using the wrong bits/c++config.h with -m32, probably
because of some variable in your environment.
