And which is the best.<BR /><BR />Thanks a lot,<BR />Dinghou Fri, 12 Apr 2002 10:47:52 GMT https://community.hpe.com/t5/operating-system-hp-ux/c-c-comparision/m-p/2702499#M723476 Dinghou Jin 2002-04-12T10:47:52Z https://community.hpe.com/t5/operating-system-hp-ux/c-c-comparision/m-p/2702500#M723477 Hi Dinghou,<BR /><BR />I really cannot which of the mentioned HW vendors produces/ships *the* best compiler.<BR />But I think it goes without saying that the compiler native to a certain platform should produce the most efficient binaries on its own platform, and excel those produced by a cross-platform compiler.<BR /><BR />However, most times it's simply a matter of availability which forces you to rely on e.g. GNUs' gcc (as in my case).
