Hello, I use the 1.9.44 version of the library and GCC 4.1.2. I realize that static assertions are not fired when they are attended. I check the STLSOFT_CF_STATIC_ASSERT_SUPPORT definition in stlsoft/stlsoft.h ----------------------------------------------- #if defined(STLSOFT_CF_STATIC_ASSERT_SUPPORT) ( __GNUC__ < 3 || \ ( __GNUC__ == 3 && \ __GNUC_MINOR__ < 4))) || \ defined(STLSOFT_COMPILER_IS_INTEL) 1 : -1]; } while(0) 0]; } while(0) ------------------------------------------------- So with gcc 4.x, STATIC_ASSERT expands to ...ai[0].... But accordingly to http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Zero-Length.html#Zero-Length array of 0 length are allowed. That explains why the static assertion cannot make the trick. We have to define -1 length. I really have not the knowledge of gcc, have I missunderstand something ? Thanks you Manfred

Matthew Wilson <no-one nowhere.none.com> Manfred Thanks for the heads-up. I'll adjust accordingly in the next release Cheers Matt ehrhart.dev.nospam free.fr Wrote:Hello, I use the 1.9.44 version of the library and GCC 4.1.2.
