Answer 1

A linker error means that you have the correct header files included (so your #include's are fine), but you're not linking to the correct libraries (usually .lib files). You need to find the libraries (usually in a lib folder near the include files) and tell the linker to use them.

Answer 2

I read this twice. The way you layer longer story-related prose is admirable, and something I have much trouble with. You make it seem effortless, natural, but all of us who write know the opposite is true. I often measure the effectiveness of a piece by the number of TD's........Jealousy rears it's green head. Kudos to you, Mr Carney.

Answer 3

these errors r generally encountered when u change ur directory or u wanna save files in a different folder..



try copying all the header files to the forder 're using.... or change the settings(for directory of header files) in the IDE that u're using..

Answer 4

i think your bin directory is not defined properly. i programmed in turbo c++, so i dont really know where it would be in bloodshed, but it should be somewhere around "Directories" setting under some tools/options/preferences thingies
