Hello everyone, I am trying out cryptopp-565 to see if it resolves the problems I have been seeing on Solaris 11 using the Sun compiler version 12.4. To this end I have written a standalone program that shows the problem. When I got version 565 I thought I would try building my test program with g++ first. The cryptopp lib itself builds fine and the tests all run and pass. The benchworks also seem ok. And it all works on RHEL 6.8 and my test program works ok there also. But on solaris 11 where I have g++ version 4.8.2 I get a compilation error:
g++ -DNDEBUG -g2 -O2 -fPIC -pipe -c apmtest.cpp In file included from apmtest.cpp:6:0: config.h:582:34: error: operator '>=' has no left operand #if ((__ILP32__ >= 1) || (_ILP32 >= 1)) && defined(__x86_64__) Since this is fine on RHEL I presume the problem is related to the solaris environment. It looks like there the _IP32 macro is not defined. I notice that the Sun/Oracle documentation at https://docs.oracle.com/cd/E19683-01/806-6543/chapter4-2/index.html says that this macro is used to say that the sizes of int, long, and pointer are all 32 bits. There is something strange about that macro though. Here is another little program that fails to compile:- #include <iostream> int main() { #if defined(_ILP32) std::cout << "_ILP32 macro is [" << _ILP32 << "]\n"; #else std::cout << "_ILP32 macro is not defined.\n"; #endif return 0; } This fails with: huh.cpp: In function int main(): huh.cpp:6:48: error: expected primary-expression before << token std::cout << "_ILP32 macro is [" << _ILP32 << "]\n"; Is anyone else seeing this issue with g++? This program compiles ok on RHEL and outputs that _ILP32 is not defined. If I change the cryptopp header config.h bit to read: #if defined(__x86_64__) && ((__ILP32__ >= 1) || defined(_ILP32)) then the problem goes away. This indicates to me that it is a bug in cryptopp-585 in that one is not supposed to use or test the macro value for _ILP32, only that it is defined.
