This may be a stupid question, but I didn't find anything by googling
gcc, g++, STL. So:
There are no STL header files in some versions of g++:
The program works on some g++'s, but not on others:
#include <algorithm>
#include <iostream>
#include <functional>
using namespace std;
template <class T>
class PrintGt5: public unary_function<T, void>
{
public:
PrintGt5(){}
void operator()(T a) { if (a > T(5)) cout << a << ' '; }
};
main()
{
int ar [10], i;
for(i=0; i < 10; i++) ar[i] = i;
for_each(ar, ar+10, PrintGt5<int>());
cout << endl;
return 0;
}

STLport also won't compile, because it seems to expect _some_ headers
from g++. I configured gcc for c,c++,ada support. Version is gcc
3.4.6 with ada-2005.
The above program won't work on this:
g++ -v
Reading specs from
/usr/local/lib/gcc/sparc-unknown-linux-gnu/3.4.6/specs
Configured with: ../gcc-34/configure --enable-shared
--enable-threads=posix --disable-checking --with-cpu=v7
--enable-languages=c,c++,ada
Thread model: posix
gcc version 3.4.6 for GNAT GPL 2006 (20060522)
The above program works on this one:
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--host=i386-redhat-linux
Thread model: posix
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
What's up with STL support in g++? Is there some add-on for STL?
Thanks,
