If you have access to news groups you really probably ought to ask programming related questions in comp.os.unix.programmer, you'll probably get much quicker and more correct responses. If you have missing pieces of the development library, it's not like you can just drop in a header file and get things to work. Also, if you are missing a file or two, chances are your development files are severly hosed and you'll find that a lot more then just one or two files are missing. FYI, iostream is part of the C++ library, and fstream.h is part of the C library. I'm surprised that when doing an installation there that the developer type is a choice, it would seem that Mandrake would force you to get this regardless of what kind of installation you get because, eventually, if you are downloading software for you system you'll have to compile something sooner or later. -----Original Message----- From: Tyler Longren [mailto:[EMAIL PROTECTED]] Sent: Sunday, October 15, 2000 12:08 PM To: Mandrake Newbie Subject: [newbie] where's the iostream library? Hi everybody, I need iostream to compile jags (smbclient frontend), but it can't be found on my system. Actually, I need fstream.h, and I think that's part of iostream. Can anybody help me find it? Thanks! Tyler Longren
