I've tried to build sage-4.3.2 on Solaris 10 using gcc 4.4.3 (the latest
version). It is complaining about some code in NTL, specicially the use of 'if'
and 'define' include/NTL/config.h.
I'm not a C++ programmer. It is normal to put 'if' and 'define' on two lines
like this below?
#if /* This is line 57, the first errror */
#define NTL_STD_CXX
I know in C, I'd use
#ifdef NTL_STD_CXX
But perhaps C++ is supposed to permit this. Anyway, for whatever reason, gcc
4.4.3 on Solaris will not accept this - see below. But it does not seem to find
iostream.h, which might be a result of, or a cause of the error.
Any thoughts you C++ programmers?
